Abstract
Background: Evidence suggests that high-dose statin pretreatment may
reduce the risk of periprocedural myocardial infarction (PMI) and major
adverse cardiac events (MACE) for certain patients; however, previous
analyses have not considered patients with a history of statin maintenance
treatment. In this meta-analysis of randomized controlled trials (RCTs),
we reevaluated the efficacy of short-term high-dose statin pretreatment to
prevent PMI and MACE in an expanded set of patients undergoing elective
percutaneous coronary intervention.
Methods: We searched the PubMed/Medline database for RCTs that compared
high-dose statin pretreatment with no statin or low-dose statin
pretreatment as a prevention of PMI and MACE. We evaluated the incidence
of PMI and MACE, including death, spontaneous myocardial infarction, and
target vessel revascularization at the longest follow-up for each study
for subgroups stratified by disease classification and prior low-dose
statin treatment.
Results: Twenty-four RCTs with a total of 5,526 patients were identified.
High-dose statin pretreatment was associated with 59% relative reduction
in PMI (odds ratio [OR]: 0.41; 95% confidence interval [CI]: 0.34-0.49;
P<0.00001) and 39% relative reduction in MACE (OR: 0.61; 95% CI:
0.45-0.83; P=0.002). The benefit of highdose statin pretreatment on MACE
was significant for statin-naive patients (OR: 0.69; 95% CI: 0.50-0.95;
P=0.02) and prior low dose statin-treated patients (OR: 0.28; 95% CI:
0.12-0.65; P=0.003); and for patients with acute coronary syndrome (OR:
0.52; 95% CI: 0.34-0.79; P=0.003), but not for patients with stable angina
(OR: 0.71; 95% CI 0.45-1.10; P=0.12). Long-term effects on survival were
less obvious.
Conclusions: High-dose statin pretreatment can result in a significant
reduction in PMI and MACE for patients undergoing elective PCI. The
positive effect of highdose statin pretreatment on PMI and MACE is
significant for statin-naive patients and patients with prior treatment.
The positive effect of high-dose statin pretreatment on MACE is
significant for patients with acute coronary syndrome.

Abstract
Objectives: Remote ischemic conditioning (RIC) by repetitive blood
pressure cuff inflation/deflation around a limb provides cardioprotection
in patients undergoing coronary artery bypass grafting (CABG).
Cardioprotection is confounded by risk factors, comorbidities and
comedications. We aimed to identify confounders that possibly attenuate
the protection provided by RIC. Methods: In a retrospective analysis of
our single-center, randomized, double-blind trial of patients undergoing
elective CABG with/without RIC prior to ischemic cardioplegic arrest, we
analyzed demographics, medications and intraoperative variables. The
primary end point was myocardial injury, as reflected by the area under
the curve for serum troponin I (TnI) from baseline to 72 h after surgery.
Results: In models with 2 independent variables and in the multivariate
analysis, age and aortic cross-clamp time impacted on TnI release.
Subgroup analyses confirmed RIC-induced protection in all age tertiles.
There was no protection with an aortic cross-clamp time . 56 min
(RIC/control = 1.026 not significant), but there was protection with 57.75
min (RIC/control = 0.757; p = 0.0348) and . 76 min (RIC/control = 0.735; p
= 0.0277). Gender, A-blockers, statins, angiotensin-converting enzyme
(ACE) inhibitors or angiotensin receptor blockers (ARBs) and
intraoperative nitroglycerine did not impact on TnI release. Conclusion:
Age, gender,-blockers, statins, ACE inhibitors, ARBs and intraoperative
nitroglycerine have no significant impact on RIC-induced cardioprotection
during CABG. However, greater myocardial ischemia/reperfusion injury at
longer cross-clamp time facilitates the detection of protection by RIC.

Abstract
background: Evidence regarding the effectiveness of incentive spirometry
(ISy) on postoperative pulmonary outcomes after thoracic, cardiac and
abdominal surgery remains inconclusive. This is attributed to various
methodological issues inherent in ISy trials. Patient compliance has also
been highlighted as a possible confounding factor; however, the status of
evidence regarding patient compliance in these trials is unknown.
Objective: To explore the status of evidence on patient compliance with
ISy interventions in randomized controlled trials (RCTs) in the above
contexts. Method: A systematic search using MEDLINE, EMBASE and CINAHL
databases was conducted to obtain relevant RCTs from 1972 to 2015 using
the inclusion criteria. These were examined for specific ISy parameters,
methods used for determining compliance and reporting on compliance. Main
outcome measures were comparison of ISy parameters prescribed and
assessed, and reporting on compliance. RESULTS: Thirty-six relevant RCTs
were obtained. Six ISy parameters were identified in ISy prescriptions
from these trials. Almost all (97.2%) of the trials had ISy prescriptions
with specific parameters. Wilcoxon signedrank test revealed that the ISy
parameters assessed were significantly lower (Z=-5.433; P<0.001) than
those prescribed; 66.7% of the trials indicated use of various methods to
assess these parameters. Only six (16.7%) trials included reports on
compliance; however, these were also incomprehensive. Conclusions: There
is a scarcity and inconsistency of evidence regarding ISy compliance.
Compliance data should be obtained using reliable and standardized methods
to facilitate comparisons between and among trials. These should be
reported comprehensively to facilitate valid inferences regarding ISy
intervention effectiveness.

Abstract
Background: The effects of neuromuscular electrical stimulation (NMES) in
critically ill patients after cardiothoracic surgery are unknown. The
objectives were to investigate whether NMES prevents loss of muscle layer
thickness (MLT) and strength and to observe the time variation of MLT and
strength from preoperative day to hospital discharge. Methods: In this
randomized controlled trial, 54 critically ill patients were randomized
into four strata based on the SAPS II score. Patients were blinded to the
intervention. In the intervention group, quadriceps muscles were
electrically stimulated bilaterally from the first postoperative day until
ICU discharge for a maximum of 14 days. In the control group, the
electrodes were applied, but no electricity was delivered. The primary
outcomes were MLT measured by ultrasonography and muscle strength
evaluated with the Medical Research Council (MRC) scale. The secondary
functional outcomes were average mobility level, FIM score, Timed Up and
Go Test and SF-12 health survey. Additional variables of interest were
grip strength and the relation between fluid balance and MLT. Linear mixed
models were used to assess the effect of NMES on MLT, MRC score and grip
strength. Results: NMES had no significant effect on MLT. Patients in the
NMES group regained muscle strength 4.5 times faster than patients in the
control group. During the first three postoperative days, there was a
positive correlation between change in MLT and cumulative fluid balance
(r=0.43, P=0.01). At hospital discharge, all patients regained
preoperative levels of muscle strength, but not of MLT. Patients did not
regain their preoperative levels of average mobility (P=0.04) and FIM
score (P=0.02) at hospital discharge, independent of group allocation.
Conclusions: NMES had no effect on MLT, but was associated with a higher
rate in regaining muscle strength during the ICU stay. Regression of
intramuscular edema during the ICU stay interfered with measurement of
changes in MLT. At hospital discharge patients had regained preoperative
levels of muscle strength, but still showed residual functional disability
and decreased MLT compared to pre-ICU levels in both groups. Trial
registration: Clinicaltrials.gov identifier NCT02391103. Registered on 7
March 2015.

Abstract
Patients with chronic kidney disease (CKD) and end-stage renal disease
(ESRD) on dialysis have an increased risk for cardiovascular mortality and
morbidity secondary to occlusive coronary artery disease. Optimal
revascularization strategy is unclear in this high-risk population. We
have performed a meta-analysis to compare coronary artery bypass grafting
(CABG) versus percutaneous coronary intervention (PCI) in patients with
ESRD and CKD. We searched PubMed, Ovid, MEDLINE, CINAHL, and EMBASE
(19802013) and found 17 trials (N 5 33,584) in the ESRD arm and 6 studies
(n 5 15,493) in the CKD arm. Two investigators independently collected the
data. All the studies were retrospective trials. In the ESRD and CKD
groups, we found significantly reduced early mortality with the PCI group
with the odds ratio of 2.08 (1.902.26; P , 0.00001) and 2.55 (1.454.51; P
5 0.001), respectively. Contrary to the early mortality results, we found
decreased late mortality with the CABG group when compared with the PCI
group [odds ratio: 0.86 (0.830.89; P , 0.000001) and 0.82 (0.760.88; P ,
0.00001)] in the ESRD and CKD arm, respectively. When compared with PCI,
there was decreased cardiovascular mortality with an odds ratio of 0.61
(0.400.92; P 5 0.02) in patients who underwent CABG in ESRD population.
Similar trends were observed in the incidence of myocardial infarction and
repeat revascularization. There is a strong trend for decreased risk of
stroke with PCI when compared with CABG in ESRD and CKD populations.

Abstract
Objective: To determine the effect of preoperative patient and hospital
factors on resource use, cost and length of stay (LOS) among patients
undergoing offpump coronary artery bypass grafting (OPCAB). Design:
Observational retrospective study. Settings: Data from the Japanese
Administrative Database. Participants: Patients who underwent isolated,
elective OPCAB between April 2011 and March 2012. Primary outcome
measures: The primary outcomes of this study were inpatient cost and LOS
associated with OPCAB. A two-level hierarchical linear model was used to
examine the effects of patient and hospital characteristics on inpatient
costs and LOS. The independent variables were patient and hospital
factors. Results: We identified 2491 patients who underwent OPCAB at 268
hospitals. The mean cost of OPCAB was $40 665 +/-7774, and the mean LOS
was 23.4+/-8.2 days. The study found that select patient factors and
certain comorbidities were associated with a high cost and long LOS. A
high hospital OPCAB volume was associated with a low cost (-6.6%; p=0.024)
as well as a short LOS (-17.6%, p<0.001). Conclusions: The hospital OPCAB
volume is associated with efficient resource use. The findings of the
present study indicate the need to focus on hospital elective OPCAB volume
in Japan in order to improve cost and LOS.

Abstract
Background The systolic forward travelling compression wave (sFCW) and
diastolic backward travelling decompression waves (dBEW) predominantly
accelerate coronary blood flow. The effect of a coronary stenosis on the
intensity of these waves in the distal vessel is unknown. We investigated
the relationship between established physiological indices of hyperemic
coronary flow and the intensity of the two major accelerative coronary
waves identified by Coronary Wave Intensity analysis (CWIA). Methodology /
Principal Findings Simultaneous intracoronary pressure and velocity
measurement was performed during adenosine induced hyperemia in 17
patients with pressure / Doppler flow wires positioned distal to the
target lesion. CWI profiles were generated from this data. Fractional Flow
Reserve (FFR) and Coronary Flow Velocity Reserve (CFVR) were calculated
concurrently. The intensity of the dBEW was significantly correlated with
FFR (R = -0.70, P = 0.003) and CFVR (R = -0.73, P = 0.001). The intensity
of the sFCW was also significantly correlated with baseline FFR (R = 0.71,
p = 0.002) and CFVR (R = 0.59, P = 0.01). Stenting of the target lesion
resulted in a median 178% (interquartile range 55-280%) (P0.0001) increase
in sFCW intensity and a median 117% (interquartile range 27-509%) (P =
0.001) increase in dBEW intensity. The increase in accelerative wave
intensity following PCI was proportionate to the baseline FFR and CFVR,
such that stenting of lesions associated with the greatest flow limitation
(lowest FFR and CFVR) resulted in the largest increases in wave intensity.
Conclusions Increasing ischemia severity is associated with proportionate
reductions in cumulative intensity of both major accelerative coronary
waves. Impaired diastolic microvascular decompression may represent a
novel, important pathophysiologic mechanism driving the reduction in
coronary blood flow in the setting of an epicardial stenosis.

Abstract
Purpose: To conduct a systematic review and meta-analysis of complication
rates and outcomes in patients undergoing endovascular procedures who
receive uninterrupted versus interrupted warfarin therapy. Materials and
Methods: Literature published between 1990 and 2014 was searched for
reports of comparative studies of vascular procedures. Information on
periprocedural complications and patient deaths less than 30 days after
the procedure was extracted. A random effects model was used and odds
ratios (ORs) were reported. An OR of less than 1 was considered to
indicate lower risk of the outcome with uninterrupted warfarin therapy.
Meta-analysis was conducted by using meta-analysis software. Results: A
total of 27 studies of 20 376 patients were included. For arterial
procedures, there were no significant differences between the
uninterrupted and interrupted warfarin therapy groups in access site
hematoma (OR, 0.59; 95% confidence interval [CI]: 0.33, 1.03; P = .06),
any bleeding complications (OR, 0.56; 95% CI: 0.30, 1.06; P = .07),
mortality (OR, 1.40; 95% CI: 0.37, 5.25; P = .62), intracranial hemorrhage
(OR, 0.55; 95% CI: 0.03, 8.91; P = .68), ischemic stroke (OR, 0.85; 95%
CI: 0.12, 5.84; P = .87), and major bleeding (OR, 0.56; 95% CI: 0.21,
1.51; P = .25). For venous procedures, uninterrupted warfarin was
associated with lower odds of access site hematoma (OR, 0.70; 95% CI:
0.50, 0.99; P = .04), any bleeding complications (OR, 0.61; 95% CI: 0.48,
0.77; P <01), ischemic stroke (OR, 0.21; 95% CI: 0.10, 0.45; P <01), and
major bleeding (OR, 0.64; 95% CI: 0.51, 0.80; P <01). For arterial and
venous procedures combined, uninterrupted warfarin was associated with
lower odds of access site hematoma (OR, 0.68; 95% CI: 0.51, 0.91; P =
.01), bleeding complications (OR, 0.59; 95% CI: 0.48, 0.74; P <01),
ischemic stroke (OR, 0.25; 95% CI: 0.12, 0.50; P <01), and major bleeding
(OR, 0.61; 95% CI: 0.49, 0.77; P <01). Heterogeneity in most analyses was
low, and confidence in the estimates was moderate. Conclusion:
Uninterrupted perioperative warfarin therapy is safe for patients
undergoing arterial procedures, but interrupted warfarin may be preferred
for those undergoing venous procedures; no differences in outcome rates
were found in the randomized controlled trials. Future studies should be
performed to validate these results.

Abstract
Aims: To review the outcomes of studies and the safety of newer
transcatheter aortic valves (THV). Methods and results: All studies
reporting on second-generation THV were identified and pooled using the
systematic review guidelines. Twenty-four reports on 1,708 patients and
eight THV were included in the analysis. The pooled 30-day event rate for
mortality after transcatheter aortic valve implantation (TAVI) was 5.7%
(95% CI: 4.0-7.8), myocardial infarction (MI) was 1.7% (95% CI: 1.1-2.6),
stage 3 acute kidney injury (AKI) was 3.4% (95% CI: 2.0-5.6),
life-threatening bleeding was 5.1% (95% CI: 3.3-7.8), major vascular
complications was 4.9% (95% CI: 3.5-6.6%), major bleeding was 10.5% (95%
CI: 5.1-20.4), major stroke was 2.4% (95% CI: 1.7-3.4), permanent
pacemaker utilisation was 13.5% (95% CI: 10.8-16.9), and coronary
obstruction was 1.2% (95% CI: 0.6%-2.4%). Moderate or severe aortic
insufficiency (AI) after TAVI was 4.2% (95% CI: 2.0-8.5). The pooled
30-day mean gradient and effective orifice area (EOA) were 11.63 mmHg (95%
CI: 10.19-13.07) and 1.60 cm2 (95% CI: 1.5-1.7), respectively. All
estimates compare favourably to events reported for first-generation
valves. Conclusions: Our findings suggest that the new THV have a low risk
of TAVI-related short-term complications.

Abstract
Background Transcatheter aortic valve replacement (TAVR) and surgical
aortic valve replacement (SAVR) are treatment options for aortic stenosis
in patients with prior coronary artery bypass graft surgery. We assessed
the major clinical outcomes of such patients enrolled in the CoreValve
High Risk (CHR) study. Methods Of the 795 CHR study patients, 226 had
prior coronary artery bypass graft surgery; 115 underwent TAVR and 111
underwent SAVR. The primary endpoint was a comparison of all-cause
mortality at 1 year. Important secondary clinical endpoints were assessed.
Results At 1 year, all-cause mortality was 9.6% for TAVR versus 18.1% for
SAVR (p = 0.06); cardiovascular mortality was 7.0% for TAVR versus 13.8%
for SAVR (p = 0.09). A combination of The Society of Thoracic Surgeons
risk score greater than 7 and age greater than 80 years was a significant
predictor of mortality, with TAVR demonstrating a survival advantage (p =
0.03). No differences were seen for stroke. The SAVR group had longer
intensive care unit and hospital stays, increased incidence of acute
kidney injury, life-threatening or disabling bleeding, and major adverse
cardiac and cerebrovascular events (p < 0.05). Pacemaker implantation and
paravalvular regurgitation were greater with TAVR at all timepoints.
Conclusions For patients with prior coronary artery bypass graft surgery
and aortic stenosis, TAVR offers a significant morbidity advantage and a
strong trend toward improved survival over SAVR at 1 year.

Abstract
Background: Postoperative delirium (POD) is a serious complication after
cardiac surgery. Use of dexmedetomidine to prevent delirium is
controversial. The authors hypothesized that dexmedetomidine sedation
after cardiac surgery would reduce the incidence of POD. Methods: After
institutional ethics review board approval, and informed consent, a
single-blinded, prospective, randomized controlled trial was conducted in
patients 60 yr or older undergoing cardiac surgery. Patients with a
history of serious mental illness, delirium, and severe dementia were
excluded. Upon admission to intensive care unit (ICU), patients received
either dexmedetomidine (0.4 mug/kg bolus followed by 0.2 to 0.7 mug
kg^-1 h^-1 infusion) or propofol (25 to 50 mug
kg^-1 min^-1 infusion) according to a
computer-generated randomization code in blocks of four. Assessment of
delirium was performed with confusion assessment method for ICU or
confusion assessment method after discharge from ICU at 12-h intervals
during the 5 postoperative days. Primary outcome was the incidence of POD.
Results: POD was present in 16 of 91 (17.5%) and 29 of 92 (31.5%) patients
in dexmedetomidine and propofol groups, respectively (odds ratio, 0.46;
95% CI, 0.23 to 0.92; P = 0.028). Median onset of POD was on postoperative
day 2 (1 to 4 days) versus 1 (1 to 4 days), P = 0.027, and duration of POD
2 days (1 to 4 days) versus 3 days (1 to 5 days), P = 0.04, in
dexmedetomidine and propofol groups, respectively. Conclusions: When
compared with propofol, dexmedetomidine sedation reduced incidence,
delayed onset, and shortened duration of POD in elderly patients after
cardiac surgery. The absolute risk reduction for POD was 14%, with a
number needed to treat of 7.1.

Abstract
Objectives The purpose of this study was to determine the safety and
effectiveness of the SAPIEN XT versus SAPIEN systems (Edwards
Lifesciences, Irvine, California) in patients with symptomatic, severe
aortic stenosis (AS) who were not candidates for surgery. Background
Transcatheter aortic valve replacement (TAVR) has become the standard of
care for inoperable patients with severe, symptomatic AS. In the PARTNER
(Placement of Aortic Transcatheter Valves) IB trial, a reduction in
all-cause mortality was observed in patients undergoing TAVR with the
balloon-expandable SAPIEN transcatheter heart valve compared with standard
therapy, but the SAPIEN valve was associated with adverse periprocedural
complications, including vascular complications, major bleeding, and
paravalvular regurgitation. The newer, low-profile SAPIEN XT system was
developed to reduce these adverse events. Methods A total of 560 patients
were enrolled at 28 sites in the United States from April 2011 to February
2012. Patients were randomized to receive the SAPIEN or SAPIEN XT systems.
The primary endpoint was a nonhierarchical composite of all-cause
mortality, major stroke, and rehospitalization at 1 year in the
intention-to-treat population, assessed by noninferiority testing.
Pre-specified secondary endpoints included cardiovascular death, New York
Heart Association functional class, myocardial infarction, stroke, acute
kidney injury, vascular complications, bleeding, 6-min walk distance, and
valve performance (by echocardiography). Results Both overall and major
vascular complications were higher at 30 days in patients undergoing TAVR
with SAPIEN compared with SAPIEN XT (overall: 22.1% vs. 15.5%; p = 0.04;
major: 15.2% vs. 9.5%; p = 0.04). Bleeding requiring blood transfusions
was also more frequent with SAPIEN compared with SAPIEN XT (10.6% vs.
5.3%; p = 0.02). At 1-year follow-up, the nonhierarchical composite of
all-cause mortality, major stroke, or rehospitalization was similar (37.7%
SAPIEN vs. 37.2% SAPIEN XT; noninferiority p value <0.002); no differences
in the other major pre-specified endpoints were found. Conclusions In
inoperable patients with severe, symptomatic AS, the lower-profile SAPIEN
XT is noninferior to SAPIEN with fewer vascular complications and a lesser
need for blood transfusion. (The PARTNER II Trial: Placement of AoRTic
TraNscathetER Valves; NCT01314313).

Abstract
Background-There is currently no accepted standard for reporting outcomes
following cardiac surgery. The objective of this paper was to
systematically review the literature to evaluate the current use and
definition of perioperative outcomes reported in cardiac surgery trials.
Methods and Results-We reviewed 5 prominent medical and surgical journals
on Medline from January 1, 2010, to June 30, 2014, for randomized
controlled trials involving coronary artery bypass grafting and/or valve
surgery. We identified 34 trials meeting inclusion criteria. Sample sizes
ranged from 57 to 4752 participants (median 351). Composite end points
were used as a primary outcome in 56% (n=19) of the randomized controlled
trials and as a secondary outcome in 12% (n=4). There were 14 different
composite end points. Mortality at any time (all-cause and/or
cardiovascular) was reported as an individual end point or as part of a
combined end point in 82% (n=28), myocardial infarction was reported in
68% (n=23), and bleeding was reported in 24% (n=8). Patient-centered
outcomes, such as quality of life and functional classification, were
reported in 29% (n=10). Definition of clinical events such as myocardial
infarction, stroke, renal failure, and bleeding varied considerably among
trials, particularly for postoperative myocardial infarction and bleeding,
for which 8 different definitions were used for each. Conclusions-Outcome
reporting in the cardiac surgery literature is heterogeneous, and efforts
should be made to standardize the outcomes reported and the definitions
used to ascertain them. The development of standardizing outcome reporting
is an essential step toward strengthening the process of evidence-based
care in cardiac surgery.

Abstract
Background Anticoagulation is required during transcatheter aortic valve
replacement (TAVR) procedures. Although an optimal regimen has not been
determined, heparin is mainly used. Direct thrombin inhibition with
bivalirudin may be an effective alternative to heparin as the procedural
anticoagulant agent in this setting. Objectives The goal of this study was
to determine whether bivalirudin offers an alternative to heparin as the
procedural anticoagulant agent in patients undergoing TAVR. Methods A
total of 802 patients with aortic stenosis were randomized to undergo
transfemoral TAVR with bivalirudin versus unfractionated heparin during
the procedure. The 2 primary endpoints were major bleeding within 48 h or
before hospital discharge (whichever occurred first) and 30-day net
adverse clinical events, defined as the combination of major adverse
cardiovascular events (all-cause mortality, myocardial infarction, or
stroke) and major bleeding. Results Anticoagulation with bivalirudin
versus heparin did not meet superiority because it did not result in
significantly lower rates of major bleeding at 48 h (6.9% vs. 9.0%;
relative risk: 0.77; 95% confidence interval [CI]: 0.48 to 1.23; p = 0.27)
or net adverse cardiovascular events at 30 days (14.4% vs. 16.1%; relative
risk: 0.89; 95% CI: 0.64 to 1.24; risk difference: -1.72; 95% CI: -6.70 to
3.25; p = 0.50); regarding the latter, the prespecified noninferiority
hypothesis was met (p<inf>noninferiority</inf> < 0.01). Rates of major
adverse cardiovascular events at 48 h were not significantly different
(3.5% vs. 4.8%; relative risk: 0.73; 95% CI: 0.37 to 1.43; p = 0.35). At
48 h, the bivalirudin group had significantly fewer myocardial infarctions
but more acute kidney injury events than the heparin group; at 30 days,
these differences were no longer significant. Conclusions In this
randomized trial of TAVR procedural pharmacotherapy, bivalirudin did not
reduce rates of major bleeding at 48 h or net adverse cardiovascular
events within 30 days compared with heparin. Although superiority was not
shown, the noninferiority hypothesis was met with respect to the latter
factor. Given the lower cost, heparin should remain the standard of care,
and bivalirudin can be an alternative anticoagulant option in patients
unable to receive heparin in TAVR. (International, Multi-center,
Open-label, Randomized Controlled Trial in Patients Undergoing TAVR to
Determine the Treatment Effect [Both Safety and Efficacy] of Using
Bivalirudin Instead of UFH [BRAVO-2/3]; NCT01651780)

Abstract
Background In EVEREST II (Endovascular Valve Edge-to-Edge Repair Study),
treatment of mitral regurgitation (MR) with a novel percutaneous device
showed superior safety compared with surgery, but less effective reduction
in MR at 1 year. Objectives This study sought to evaluate the final 5-year
clinical outcomes and durability of percutaneous mitral valve (MV) repair
with the MitraClip device compared with conventional MV surgery. Methods
Patients with grade 3+ or 4+ MR were randomly assigned to percutaneous
repair with the device or conventional MV surgery in a 2:1 ratio (178:80).
Patients prospectively consented to 5 years of follow-up. Results At 5
years, the rate of the composite endpoint of freedom from death, surgery,
or 3+ or 4+ MR in the as-treated population was 44.2% versus 64.3% in the
percutaneous repair and surgical groups, respectively (p = 0.01). The
difference was driven by increased rates of 3+ to 4+ MR (12.3% vs. 1.8%; p
= 0.02) and surgery (27.9% vs. 8.9%; p = 0.003) with percutaneous repair.
After percutaneous repair, 78% of surgeries occurred within the first 6
months. Beyond 6 months, rates of surgery and moderate-to-severe MR were
comparable between groups. Five-year mortality rates were 20.8% and 26.8%
(p = 0.4) for percutaneous repair and surgery, respectively. In
multivariable analysis, treatment strategy was not associated with
survival. Conclusions Patients treated with percutaneous repair more
commonly required surgery for residual MR during the first year after
treatment, but between 1- and 5-year follow-up, comparably low rates of
surgery for MV dysfunction with either percutaneous or surgical therapy
endorse the durability of MR reduction with both repair techniques.

Abstract
The objective was to evaluate the effect of epinephrine and levosimendan
on the left ventricle myocardial performance index in patients undergoing
on-pump coronary artery by-pass grafting (CABG). Methods In a
double-blind, randomized clinical trial, 81 patients (age: 45a"65 years)
of both genders were randomly divided to receive either epinephrine at a
dosage of 0.06 mcg.kg1.min-1 (epinephrine group, 39 patients) or
levosimendan at 0.2 mcg.kg1.min-1 (levosimendan group, 42 patients) during
the rewarming of cardiopulmonary by-pass (CPB). Hemodynamic data were
collected 30 minutes after tracheal intubation, before chest open
(pre-CPB) and 10 minutes after termination of protamine (post-CPB). As the
primary outcome, we evaluated the left ventricle myocardial performance
index by the Doppler echocardiography. The myocardial performance index is
the sum of the isovolumetric contraction time and the isovolumetric
relaxation time, divided by the ejection time. Secondary outcomes were
systolic and diastolic evaluations of the left ventricle and postoperative
troponin I and MB-CK levels. Results Of the 81 patients allocated to the
research, we excluded 2 patients in the epinephrine group and 6 patients
in the levosimendan group because they didnaTMt wean from CPB in the first
attempt. There was no statistical difference between the groups in terms
of patient characteristics, risk factors, or CPB time. The epinephrine
group had a lower left ventricle myocardial performance index (p =
0.0013), higher cardiac index (p = 0.03), lower systemic vascular
resistance index (p = 0.01), and higher heart rate (p = 0.04) than the
levosimendan group at the post-CPB period. There were no differences
between the groups in diastolic dysfunction. The epinephrine group showed
higher incidence of weaning from CPB in the first attempt (95% vs 85%, p =
0.0001) when compared to the levosimendan group and the norepinephrine
requirement was higher in the levosimenandan group than epinephrine group
(16% vs. 47%; p = 0.005) in post-CPB period. Twenty-four hours after
surgery, the plasma levels of troponin I (epinephrine group: 4.5 A+/- 5.7
vs. levosimendan group: 2.5 A+/- 3.2 g/dl; p = 0.09) and MB-CK
(epinephrine group: 50.7 A+/- 31 vs. levosimendan group: 37 A+/- 17.6
g/dl; p = 0.08) were not significantly different between the two groups.
Conclusion When compared to levosimendan, patients treated with
epinephrine had a lower left ventricle myocardial performance index in the
immediate post-CPB period, encouraging an efficient weaning from CPB in
patients undergoing on-pump CABG.

Abstract
Background Evidence is accumulating that mindfulness training has
favorable effects on psychological outcomes, but studies on physiological
outcomes are limited. Patients with heart disease have a high incidence of
physiological and psychological problems and may benefit from mindfulness
training. Our aim was to determine the beneficial physiological and
psychological effects of online mindfulness training in patients with
heart disease. Methods The study was a pragmatic randomized controlled
single-blind trial. Between June 2012 and April 2014 we randomized 324
patients (mean age 43.2 years, 53.7%male) with heart disease in a 2:1
ratio (n = 215 versus n = 109) to a 12-week onlinemindfulness training in
addition to usual care (UC) compared to UC alone. The primary outcome was
exercise capacity measured with the 6 minute walk test (6MWT). Secondary
outcomes were other physiological parameters (heart rate, blood pressure,
respiratory rate, and NT-proBNP), subjective health status (SF-36),
perceived stress (PSS), psychological well-being (HADS), social support
(PSSS12) and a composite endpoint (all-cause mortality, heart failure,
symptomatic arrhythmia, cardiac surgery, and percutaneous cardiac
intervention). Linear mixed models were used to evaluate differences
between groups on the repeated outcome measures. Results Compared to UC,
mindfulness showed a borderline significant improved 6MWT (effect size,
meters: 13.2, 95%CI: -0.02; 26.4, p = 0.050). There was also a significant
lower heart rate in favor of the mindfulness group (effect size, beats per
minute: -2.8, 95%CI: -5.4;-0.2, p = 0.033). No significant differences
were seen on other outcomes. Conclusions Mindfulness training showed
positive effects on the physiological parameters exercise capacity and
heart rate and it might therefore be a useful adjunct to current clinical
therapy in patients with heart disease.

Abstract
Introduction: Hypotensive state is frequently observed in several critical
conditions. If an adequate mean arterial pressure is not promptly
restored, insufficient tissue perfusion and organ dysfunction may develop.
Fluids and catecholamines are the cornerstone of critical hypotensive
states management. Catecholamines side effects such as increased
myocardial oxygen consumption and development of arrhythmias are well
known. Thus, in recent years, interest in catecholamine-sparing agents
such as vasopressin, terlipressin and methylene blue has increased;
however, few randomized trials, mostly with small sample sizes, have been
performed. We therefore conducted a meta-analysis of randomized trials to
investigate the effect of non-catecholaminergic vasopressors on mortality.
Methods: PubMed, BioMed Central and Embase were searched (update December
31^st, 2014) by two independent investigators. Inclusion
criteria were: random allocation to treatment, at least one group
receiving a non-catecholaminergic vasopressor, patients with or at risk
for vasodilatory shock. Exclusion criteria were: crossover studies,
pediatric population, nonhuman studies, studies published as abstract
only, lack of data on mortality. Studied drugs were vasopressin,
terlipressin and methylene blue. Primary endpoint was mortality at the
longest follow-up available. Results: A total of 1,608 patients from 20
studies were included in our analysis. The studied settings were sepsis
(10/20 studies [50%]), cardiac surgery (7/20 [35%]), vasodilatory shock
due to any cause (2/20 [19%]), and acute traumatic injury (1/20 [5%]).
Overall, pooled estimates showed that treatment with non-catecholaminergic
agents improves survival (278/810 [34.3%] versus 309/798 [38.7%], risk
ratio = 0.88, 95%confidence interval = 0.79 to 0.98, p = 0.02). None of
the drugs was associated with significant reduction inmortality when
analyzed independently. Results were not confirmed when analyzing studies
with a low risk of bias. Conclusions: Catecholamine-sparing agents in
patients with or at risk for vasodilatory shock may improve survival.
Further researches on this topic are needed to confirm the finding.

Abstract
Introduction: Potassium cardioplegia-induced transient asystole may
conserve myocardial energy and improve outcome in ventricular fibrillation
(VF) cardiac arrest. Hypothesis: We hypothesized potassium infusion during
VF arrest would lead to an increase in intra-arrest amplitude spectrum
area (AMSA) prior to defibrillation, and improved hemodynamic parameters
in those animals that attained return of spontaneous circulation (ROSC).
Methods: Twelve swine were randomized to KCl or placebo in a randomized
controlled trial, and 10 were included in an amended protocol. After
initiation of monitoring, induction of anesthesia, and instrumentation of
the aorta and right atrium, VF was electrically induced. After 4 minutes,
1.5 meq/kg KCl or placebo was infused in blinded fashion in a peripheral
ear vein and mechanical chest compressions and ventilations were begun.
Initial defibrillation was performed 10 minutes post VF induction, as
appropriate. Animals without ROSC received continued resuscitation per
Advanced Cardiac Life Support(ACLS) guidelines for 10 more minutes.
Animals that achieved ROSC were monitored for 30 more minutes. The primary
outcome, change in AMSA from just before study drug infusion to 5 minutes
post infusion, was compared using nonparametric statistics. Results: Six
animals were randomized to KCl and 4 to Placebo. KCl infusion induced
approximately 1 minute of transient asystole at the dosage used. The mean
change in normalized AMSA was -0.24 in the KCl and 0.21 in the Placebo
group, with a median difference of -0.50 (95%CI -0.79 to -0.09), p=0.038,
favoring Placebo. Five of 6 (83%) animals in the KCl group and 2 of 4
(50%) in the Placebo group developed an organized, though not necessarily,
perfusing rhythm with the difference in proportion 33% (95% CI -33 to 86).
One of 6 (17%) animals in the KCl and 2 of 4 (50%) in the Placebo group
achieved ROSC with the difference in proportion -33% (95%CI -93 to 33).
Hemodynamics were not quantitatively compared post ROSC due to limited
survivors. One animal in each group required norepinephrine infusion.
Conclusions: Potassium as a single agent did not benefit AMSA or ROSC in
this porcine model of VF arrest.

Abstract
Aim: Tradition-based care dictates that patients fast for several hours
post-cardiothoracic (CT) surgery due to concerns for adverse events
(nausea, vomiting, dysphagia, aspiration pneumonia), although evidence is
lacking to support this practice. Prolonged fasting causes patients
significant distress from thirst. Our aim was to determine the effect of
an early liberal regimen of ice chips and water on adverse events and
thirst after CT surgery. We hypothesized that a liberal regimen vs. usual
care (UC) would not increase adverse events and would reduce thirst.
Method: We used a randomized controlled trial design with a sample of 149
patients from an 18-bed CTICU. Written informed consent was obtained and
patients were randomized to UC (6-hour fast post-extubation) or liberal
regimen during the pre-operative visit. After fasting 1 hour
post-extubation, patients in the liberal regimen were first assessed with
a 6-item protocol for oral intake readiness, and then offered ice chips.
An hour later, they were advanced to water. Results: The mean age was
66+/-12.4 years; 73.8% were male; 91.3% had coronary artery and/or valve
surgery. The two groups were equivalent except for the post-operative mean
dose of ketorolac that was higher in the UC group (p=.04). The table below
shows no differences in nausea, vomiting, or dysphagia between the UC vs.
liberal group, and no aspiration pneumonia. Complaints of high thirst
levels 6 hours after extubation were greater in the UC group. In analysis
adjusted for relevant demographic and clinical variables (logistic
regression), patients in the liberal group were less likely to report high
thirst levels, compared with UC patients (B=-.299, OR=.273, 95% CI
.118-.630). Conclusion: Early initiation of ice chips and water
post-extubation after CT surgery was not associated with adverse events,
but was associated with significantly less thirst. In appropriate
patients, early oral intake can reduce thirst, a distressing symptom.

Abstract
Background: Several early small trials have concerned about the renal
effect of periprocedural remote ischemic conditioning(RIC) in patients
with coronary artery disease(CAD), however, negative results were widely
obtained. Hence, we sought to summarize the renal evidence of RIC in
patients undergoing coronary artery bypass grafting(CABG) or percutaneous
coronary intervention(PCI). Methods: A systematic search was performed in
Pubmed, Embase, Cochrane library, and scientific sessions of AHA, ACC and
ESC (up to April 2015). Randomized controlled trials with data on
postoperative acute kidney injury(AKI) during elective coronary
revascularization were included. Odds ratio(OR) with 95% confidence
interval(CI) was calculated. Random-effect models were used for the
potential clinical inconsistency. Publication bias assessment and
sensitivity analysis were performed to evaluate the robustness of the
results. Results: Thirteen RCTs with a total of 1861 CAD patients were
identified and selected. Compared with controls, RIC significantly reduced
the incidence of AKI (6.61% vs 11.6%;OR= 0.54; 95% CI, 0.37 to 0.78;
P=0.001; I2=8.5%; Figure 1). No evidence of significant publication bias
were observed (P=0.784, Begg's test; P=0.096, Egger's test). Sensitivity
analysis of mortality excluding each included study at one time revealed
that most individual study was consisted with the direction and size of
the overall effect (All P>0.01).There was no significant difference
between CABG subgroup (9.8% vs 16.6%;OR=0.54;95%CI, 0.32 to 0.92; P=0.02;
I2=0.0%) and PCI subgroup(5.3% vs 9.4%;OR=0.54; 95% CI, 0.30 to
1.00;P=0.05; I2=36.5%) (P=1.00 for subgroup difference). Conclusions:
Based on the available evidence, RIC provides renal protection by reducing
the postprocedural AKI in elective coronary revascularization. Such effect
is similar between CABG and PCI.

Abstract
Introduction:The optimal treatment for congenital aortic stenosis (AS) is
debated despite decades of experience with both balloon aortic
valvuloplasty (BAV) and surgical aortic valve repair (SAV). While BAV has
been the mainstay of therapy for AS, recent single-center reports suggest
optimal results following SAV. Hypothesis: We propose that reintervention
rates following SAV and BAV are equivalent. Methods: We queried Medline,
EMBASE and Web of Science for eligible studies using the keywords:
"congenital aortic stenosis", "balloon valvotomy", "aortic valve stenosis
surgery" and "treatment outcome or reintervention". Studies were excluded
when cohort size was <20 pts, when follow-up was < 2.5 yrs from primary
intervention, and when primary indication was not AS (e.g. SAV in the
setting of aortic valve regurgitation (AR)). Outcomes analyzed included
death, reintervention and moderate or severe AR. Analysis was performed
using Comprehensive Meta Analysis v3 using random effects models. Results:
A total of 20 studies were included in our meta-analysis: SAV alone (n=3),
BAV alone (n=12), and both (n=5). The mean age at BAV was 3.1 years
(range, 4 days - 7 years) with a mean follow-up duration of 6.8 years,
while mean age at SAV was 2.8 years (range, 14.2 days - 7.1 years) with a
mean follow-up duration of 9.1 years. Mortality rates following BAV and
SAV were 12.3% (95% CI: 7.7 - 19.1) and 10.2% (95% CI: 7.0 - 14.5),
respectively (p=0.27). Reintervention following initial procedure for
treatment of AS was higher following BAV (35.7% [95% CI: 29 - 43.1])
compared to SAV (25.2% [95% CI: 19.9 - 31.3])(p=0.012). Long-term and
mid-term follow-up in these studies showed moderate to severe AR was
present in 24.1% and 28.1% of BAV and SAV patients, respectively.
Conclusions: Notwithstanding publication bias, both survival rates and
development of late AR following BAV and SAV are similar. However,
reintervention rates are significantly higher following BAV compared to
SAV.

Abstract
Introduction: Infants and children after cardiac surgery may develop
hyper- or hypoglycemia, associating with higher nosocomial infection or
neurological morbidities. Hypothesis: The hypothesis of this perspective
randomized control study is moderate glucose control may improve clinical
outcomes. Methods: We randomly assigned children(<3 years of age) who were
admitted to the pediatric cardiac intensive care unit (PICU) after
cardiopulmonary bypass surgery into either moderate glucose control group
(target blood glucose: 110-143mg per deciliter) or conventional glucose
control group (target level below 200mg per deciliter). The primary
outcome was the rate of nosocomial infection in PICU. Second outcomes
include hospital mortality, duration of mechanical ventilation and PICU
stay, and a composite morbidity variable included events of requiring
extracorporeal membrane oxygenation, delayed sternal closure,
dialysis-dependent renal failure and hypoglycemia. Results: A total of 593
patients underwent randomization: 293 to moderate glucose control group
and 300 to conventional glucose control group. The baseline data were
balanced between these two groups. Mean 72 hours time-weighted blood
glucose average was lower in the moderate control group than in the
conventional group (129.9+/-22.1 mg per deciliter vs. 138.8+/-28.6 mg per
deciliter, p<0.001). Although no statistically significance reached, there
is a trend that nosocomial infection occurred less in moderate glucose
group (17 (5.80%) vs. 29 (9.67%), P=0.054). Duration of mechanical
ventilation was shorter in the moderate control group (18 (range, 4-300)
hours vs 22 (range 3-771) hours, p=0.046). Hypoglycaemia (blood glucose
<65mg per deciliter) which occurred in 7(2.39%) patients in the moderate
group versus 8 (2.67%) in the conventional group, was statistically
similar between groups. Other secondary outcomes did not differ
significantly between groups. Conclusions: With moderate glucose control,
although the major clinical outcomes did not change, this randomized
control study showed shorter ventilation time after pediatric cardiac
surgery, substantially benefit for patients with complex congenital
cardiac anomalies.

Abstract
Background: Children requiring cardiac surgery with cardiopulmonary bypass
(CPB) frequently develop Low Cardiac Output Syndrome (LCOS), particularly
when very young, A pilot study of 16 children by Checchia et al. (2013)
showed that the delivery of nitric oxide (NO) to the CPB circuit shortened
duration of mechanical ventilation and ICU stay. We hypothesized that
administering NO to oxygenator gas flow during CPB would decrease the
incidence of LCOS and effect subsequent clinical outcomes. Methods: We
conducted a prospective, blinded, randomized controlled trial in children
with congenital heart disease having surgery with CPB. Randomization was
stratified by age and 'blocked' at six in each group. Children received
oxygen alone or 20 ppm gaseous NO and oxygen to the CPB gas administration
line. Only the study perfusionist was aware of the allocation and all
equipment and devices were otherwise identical in each group; in
particular the cardiac surgeon and anesthetist remained blinded to patient
allocation. Results: 198 children were enrolled following written consent.
There were no differences in patient characteristics, diagnoses or
surgeries between groups. 101 children received NO and had a significant
reduction in LCOS (14% vs 31%, p=0.004), use of ECMO (1% vs 8%, p=0.014)
and a non-significant reduction in ICU length of stay (48hrs vs 72hrs,
p=0.111), compared to the 97 children who did not receive NO. The
reduction in LCOS was most pronounced in children less than 6 weeks of age
(20% vs 52%, p=0.012) and in those aged 6 weeks to 2 years (6% vs 24%,
p=0.026), who also had significantly reduced ICU length of stay (43hrs vs
84hrs, p=0.031). LCOS occurred equally between groups in children greater
than 2 years of age (17% vs 21%, p=0.678). There was no difference in the
amount of post-operative bleeding in any age group. Children greater than
2 years of age who received NO required fewer blood transfusions (8.3% vs
24.1%, p=0.096). Conclusions: Delivery of NO to the CPB circuit for
children undergoing cardiac surgery significantly reduces the incidence of
LCOS, use of ECMO and ICU length of stay by varying degrees, according to
age group.

Abstract
Objectives: Acute kidney injury (AKI) is a frequent and serious
complication in infants after cardiac surgery with cardiopulmonary bypass
(CPB). Often the earliest sign is oliguria, which can lead to fluid
overload, prolonged mechanical ventilation and ICU stay, abnormal
electrolytes and increased mortality. We hypothesized that the use of
peritoneal dialysis (PD) compared to furosemide use would mitigate these
complications. Methods: This is a single-center, surgical
complexity-stratified, randomized controlled trial performed within a
cohort of patients younger than 6mo undergoing cardiac surgery with a
preoperative plan of PD catheter placement due to risk of post-CPB kidney
injury. If enrolled patients had urine output < 1mL/kg/hour for 4 hours
during the first postoperative day, the patient was randomized to either a
standardized regimen of furosemide or PD. If the patient demonstrated poor
response to furosemide, PD could be initiated on postoperative day 2.
Results: A total of 73 patients were randomized and completed the trial,
including 2 patients who were randomized to furosemide and subsequently
received PD. Using intention-to-treat analysis, the PD group was less
likely to have fluid overload, had a lower delayed-extubation rate and
fewer electrolyte replacements. There were no differences in mortality or
ICU/hospital stay. No serious PD related complications were observed. PD
was discontinued early in 9 patients due to pleural-peritoneal
communication. Conclusions: Our study demonstrates that the use of PD in
neonates with oliguria after CPB is associated with reduced morbidity but
not differences in mortality or ICU/hospital stay. A multi-center study is
necessary to further support these findings as well as determine
association with mortality.

Abstract
Introduction: Aspirin for prolonged duration is commonly prescribed to
patients with a history of cardiovascular events who are at continued risk
for occlusive vascular events (secondary prevention). Patients in the
peri-operative period are not only at an increased risk of bleeding but
also for thrombotic vascular events because of the pro-thrombotic milieu.
Hypothesis: The objective of our study was to do a systematic review and
meta-analysis to compare the risk of thrombotic events and the risk of
bleeding in patients with early (3-5 days) versus late discontinuation/no
discontinuation of aspirin. Methods: PubMed and Embase were searched to
identify the studies that report discontinuation or non-adherence of
aspirin in patients undergoing surgery. The studies were included if they
reported thrombotic events (stroke, all-cause mortality, MI, stent
thrombosis & restenosis, stroke, heart failure, VTE, acute limb ischemia,
perioperative cardiovascular complications) and perioperative bleeding.
Odds ratio was calculated for the measured outcomes. The outcomes were
pooled by generic inverse variance method in a random effects model and
corresponding forest plots were made. Quality assessment was done as per
Newcastle-Ottawa scale. Results: Our search strategy revealed 1018 studies
out of which 6 observational studies (3 evaluating cardiac and 3
non-cardiac surgeries) met the inclusion criteria. There was no difference
in the risk of thrombotic events both in early or late discontinuation of
aspirin (OR 1.17, 95% CI= 0.74-1.84, p =0.50; I2 = 56%) (Figure 1). Early
discontinuation of aspirin showed a decreased risk of peri-operative
bleeding (OR 0.82, 95% CI= 0.67-0.99; p =0.04; I2 = 42%) (Figure 2).
Conclusion: Planned discontinuation of aspirin is acceptable with no
increased risk of thrombotic events and with a decreased risk of bleeding.
Moreover the decreased risk of peri-operative complications may help
reduce the length of stay and associated co-morbidities.

Abstract
Background: The efficacy of transcatheter aortic valve replacement (TAVR)
in patients at high surgical risk has been established. The data in
patients with low-moderate risk for surgery is still not conclusive. We
sought to perform a meta-analysis of studies comparing the safety and
efficacy of TAVR with surgical aortic valve replacement (SAVR). Methods:
Several databases were searched from inception to February 2015, which
yielded 10 eligible studies. Studies were selected if they compared TAVR
to SAVR in patients at low-moderate risk for surgery. The measured
outcomes of efficacy were all-cause and cardiovascular mortality. Data on
safety included cerebrovascular events (CVA), permanent pacemaker
implantation (PPI), aortic regurgitation (AR), vascular access
complications and major bleeding reported during the procedure. Outcomes
were pooled and relative risk was calculated using the Mantel-Haenszel
method using a random effects or a fixed effect model based on
heterogeneity. If studies had zero events in any of the arms, Peto odds
ratio was used to pool data. Results: There were 10 studies with 3107
participants in our analysis. There was no difference in either short-term
(RR, 0.85; CI: 0.57-1.28; p=0.44; I2=0%) or medium to long-term all-cause
mortality (RR, 0.97; CI: 0.80-1.18; p=0.78; I2=0%). Our analysis suggested
a decreased risk of cardiovascular mortality in the short-term (RR, 0.42;
CI: 0.19-0.91; p=0.03; I2=0%) and a statistically non-significant trend
towards decrease in long-term mortality (RR, 0.53; CI: 0.26-1.08; p=0.08;
I2=0%) with TAVR. There was increased incidence of AR (RR, 4.01; CI:
2.24-7.19; p< 0.00001; I2=0%), PPI (RR, 5.00; CI: 3.47-7.19; p< 0.00001;
I2=21%) and vascular access complications (RR, 6.36; CI: 3.75-10.76; p<
0.00001; I2=27%) in patients with TAVR. There was no difference in the
risk of stroke between TAVR and SAVR (RR, 1.17; CI: 0.62-2.21; p=0.64;
I2=15%) and an increased risk of major bleeding with SAVR was found (RR,
1.81; CI: 1.08-3.03; p< 0.0001; I2=86%). Conclusions: In this
meta-analysis we found that TAVR may be an acceptable alternative to SAVR
in patients with low-moderate risk for surgery. However, more evidence is
needed from the current randomized trials before more widespread adoption
of the procedure.

Abstract
Background: There is not a single established effective and safe
intervention to prevent major perioperative vascular complications that
commonly occur in the first 30 days after noncardiac surgery. Hypothesis:
We evaluated the feasibility of a multicenter randomized controlled trial
(RCT) testing the perioperative effects of statins. Methods: This is a
double blind, placebo-controlled RCT testing a short course of
atorvastatin 80mg before surgery, followed by 40mg 12 hours after surgery
and then 40mg/day for 7 days in patients undergoing noncardiac surgery who
were at risk of a major perioperative vascular complication. The primary
outcome (major vascular events) was a composite of all-cause mortality,
nonfatal myocardial infarction, MINS (myocardial injury after noncardiac
surgery) without myocardial infarction and nonfatal stroke at 30 days
after randomization. All analysis followed the intention-to-treat
principle. Results: We enrolled 587 patients from 30 centers in Brazil.
Mean age was 66.6 years, 37.1% were males, 22.0% had previous
cardiovascular disease, 50.2% had diabetes and 89.7 % had hypertension.
The majority of participants underwent general (35.9%), orthopedic
(30.0%), gynecologic (8.4%), urologic (7.3%), and vascular (6.6%) surgery.
A total of 51 out of 300 patients (17.0%) suffered a major vascular
complication in the atorvastatin group compared to 49 out of 287 patients
(17.1%) in the control group at 30 days (hazard ratio [HR] 1,02; 95%
confidence interval (CI) 0.68 to 1.52; P = 0.93). No significant effect
was observed on the 30-day secondary outcomes of death or myocardial
infarction (8.0% versus [vs.] 7.7%, respectively; HR 0.94; 95% CI 0.52 to
1.70; P = 0.84), myocardial infarction (3.7% vs. 4.5%, respectively; HR
0.84; 95% CI 0.37 to 1.93; P = 0.68), MINS (14.0% vs.15.0%; HR 0.94; 95%
CI 0.53 to 1.67; P = 0.84), and all-cause mortality (4.7% vs. 4.5%; HR
1.22; 95% CI 0.53 to 2.78; P = 0.64). Conclusions: The LOAD Trial confirms
that a multicenter perioperative statin trial is feasible and highlights
the need for large RCTs to establish effective and safe interventions. The
study also suggests that effects of a perioperative statin on major
vascular complications are, at best, moderate in size, questioning the
robustness of prior data.

Abstract
Introduction: Multivessel coronary artery disease is present in about half
of the patients presenting with STEMI. Timing of revascularization for the
non-culprit vessels has been a long debate, with few trials suggesting
benefit at index hospitalization rather than staging them at a later time.
Current ACCF/AHA 2013 STEMI guidelines do not recommend PCI of non-infarct
artery at the time of primary PCI but recommend it at a later time if
patients are symptomatic. We hypothesized, complete revascularization
during primary PCI or index hospitalization would have favorable outcomes
compared to culprit vessel only revascularization. Aim: We performed
meta-analysis of randomized control trials comparing multivessel vs.
infarct artery only revascularization during primary PCI or index
hospitalization. Methods and Results: Pubmed, Embace and Google scholar
databases were searched for randomized control trials comparing
multivessel vs. culprit vessel only revascularization during primary PCI
or index hospitalization. We compared deaths, non-fatal MI and repeat
revascularization events for the groups. Total number of patients in our
study was 1819, with 919 patients in multivessel revascularization and 900
patients in infarct artery only revascularization groups. Mean follow up
period was 28 months. Pooled analysis showed significant favorability for
multivessel coronary revascularization comparing events of repeat
revascularization (OR= 0.39, p<0.0001). There was also non-significant
decrease in mortality (OR=0.92, p=0.7) and non-fatal MI (OR=0.68, p=0.09)
with complete revascularization. Conclusions: In our study of STEMI
patients, complete revascularization during primary PCI or index
hospitalization has significantly decreased need for repeat
revascularization and there was also non-significant decrease in mortality
and non-fatal MI. Studies with larger sample size and longer follow up are
needed for stronger evidence.

Abstract
Introduction: Atrial fibrillation is a common postoperative complication
of surgical aortic valve replacement (SAVR). However, it is not known if
the incidence of post procedure AF is impacted by performing Transcatheter
Aortic Valvular Replacement (TAVR) instead of SAVR. Hypothesis: There is
no difference in risk of post procedure incident AF in patients undergoing
TAVR vs. SAVR. Methods: We systematically reviewed studies evaluating TAVR
vs. SAVR and risk of post procedure AF. We searched MEDLINE, EMBASE,
CINAHL, Web of Science, meeting abstracts, presentations and Cochrane
central databases from inception through May 2015. For a study to be
selected, it had to report the rates of incident AF in individuals
undergoing TAVR. Data were extracted by 2 independent authors (WTQ and
UBN). Forrest plot was created to show the effect sizes (Figure 1).
Results: A total of 8 studies including 2483 patients (mean age 81.4
years, 70.3% male) were analyzed. There were 1293 patients that underwent
TAVR and 1190 patients that underwent SAVR. The 1- year incidence of AF
was 231 (17.9%) in TAVR group vs. 377 (31.6%) in SAVR group. In a random
effects model, patients treated with TAVR had a 48% decreased risk of post
procedural 1 year risk of AF [pooled Risk Ratio (95% confidence interval)
0.52 (0.37-0.73), p <0.001]. There was moderate heterogeneity in the
results (I2 = 80%). The risk of AF was higher in studies with older
patients and was lower in studies with higher proportion of patients that
underwent transfemoral TAVR vs. transapical TAVR. Conclusions: In this
meta-analysis, the post procedure risk of AF was lower in TAVR group as
compared to SAVR group. The risk of post procedure AF should be considered
while making decision for TAVR vs. SAVR.

Abstract
Introduction: Surgical left atrial appendage (LAA) closure is an option in
patients undergoing cardiac surgery who have a history of atrial
fibrillation. Despite multiple studies, it is not clear whether LAA
closure during cardiac surgery results in improved outcomes. Hypothesis:
We hypothesized that LAA closure is associated with significant decrease
in risk of stroke and mortality. Methods: We conducted Pubmed, EMBASE and
CENTRAL searches for studies comparing cardiac surgery alone or with
concomitant LAA closure. Efficacy outcome was future risk of stroke.
Safety outcomes were total mortality and postoperative bleeding. Results:
A total of six studies with 3267 patients fulfilled the inclusion
criteria. Primary surgeries were mitral valve surgeries in four studies
and coronary artery bypass grafting in 2 studies. Successful LAA closure
confirmed by trans-esophageal echocardiography was achieved in 97.8% of
patients. Concomitant left atrial appendage closure was not associated
with any significant difference in risk of future stroke (Odds ratio (OR)
0.61, 95% Confidence Interval (CI) 0.30 to 1.24, p=0.12) or recurrence of
atrial fibrillation (OR 0.92, 95% CI 0.66 to 1.29, p=0.63). However, the
combined procedure was associated with lower long-term mortality (OR 0.41,
95% CI 0.22 to 0.77, p=0.005) when compared to cardiac surgery alone.
Conclusions: Concomitant left atrial appendage closure is a safe procedure
but is not associated with a significant decrease in future risk of
stroke. Patients with LAA closure had significantly lower mortality but
this may be related to lower long term use of anticoagulants and bleeding
events in this group. These findings need to be investigated further in
large prospective studies.

Abstract
Introduction: Randomised controlled trials demonstrate that Off-Pump
Coronary Artery Bypass (OPCAB) is equivalent to On-Pump Coronary artery
bypass graft (ONCAB) for in-hospital and short-term outcomes. Recent
observational data, however, suggests that OPCAB may be associated with
increased mid-term mortality although there are several conflicting
studies. There is little data on long-term survival after OPCAB. The
objective of this study was to determine the impact of OPCAB on long-term
survival compared to ONCAB. Methods: We conducted a retrospective cohort
study using the Bristol PATS database of all patients who underwent
primary isolated CABG surgery from 1996 to 2011. Mortality data was
obtained from the Office of National Statistics. Multivariate regression
models were used to estimate the association between OPCAB and long-term
survival. Results: We evaluated long-term survival in 11,981 patients
(mean age 65.5+/-9.3 years, 2202 females) who underwent CABG (OPCAB,
n=6133; ONCAB, n=5848). Survival data was complete in 99.2% of patients,
with a median follow-up duration of 8 years (interquartile range: 4.8 to
11.8 years; maximum 17.3 years). Both groups were similar in terms of
baseline characteristics and intraoperative variables. Euroscore was 3.7
(0.03) and 3.8 (0.03) and number of distal anastomoses performed were 2.53
(0.81) and 2.92 (0.78) in the OPCAB and ONCAB groups, respectively.
Long-term survival was similar between patients undergoing OPCAB and ONCAB
(HR for death: 0.94, 95%CI 0.87 - 1.01, p=0.087). Conclusions: In patients
undergoing coronary revascularisation both ONCAB and OPCAB offer excellent
long-term survival.

Abstract
Introduction: Allogeneic red blood cell (RBC) transfusion in cardiac
surgery patients increases the risk of pulmonary and renal morbidity.
These associations are attributable to the 'storage lesion' - accumulation
of metabolites in the RBC supernatant that includes pro-inflammatory
lipids, cell-free hemoglobin and energy depletion. Hypothesis: Storage
lesion components trigger different events that lead to organ injury.
Reducing storage lesion by RBC washing or rejuvenation will reduce organ
injury. Methods: Samples from 60 cardiac patients participating in a
randomized controlled trial of RBC washing prior to transfusion versus
standard care were analysed for inflammatory markers. In a complementary
experiment, 4 groups of pigs received crystalloid infusion or 14-day old
RBC that were left untreated, washed or rejuvenated (Rejuvesol, Citra
Labs, IN). Inflammatory markers, free hemoglobin and iron were measured in
blood. Leukocyte invasion was determined by immunohistochemistry. The
results were verified and further analysed in an in vitro inflammatory
model. Results: Transfusion of stored RBC (~22 days) into humans or pigs
was associated with leukocyte activation, and attenuated by washing. That
was attributed to oxidised lipids on transfused RBC derived microvesicles
that activated monocytes and platelets, as revealed in depletion
experiments. Unexpectedly, transfusion of washed RBC increased kidney
injury, which correlated with higher free haemoglobin levels, oxidative
stress (confirmed by HMOX-1 levels and protein carbonylation), and
endothelial injury in washed RBC recipients. Oxidative stress triggered
non-standard endothelial activation defined by expression of VLA5 and
fibronectin retention. Either pathway was reduced when rejuvenated blood
was transfused. Conclusion: Monocytes/platelets and endothelium are
activated by oxidized lipids/MV and reactive free haem, respectively, and
can be alleviated by RBC rejuvenation.

Abstract
Introduction: Statins, through their immunomodulatory effects, may prevent
cardiac allograft dysfunction in heart transplant recipients. Current
International Society of Heart and Lung Transplantation (ISHLT) guidelines
recommend the use of statins in these patients. Though several studies
have demonstrated significant survival benefit with statin use, a pooled
analysis evaluating the role of statins in heart transplant recipients has
not been performed to date. We conducted a meta-analysis to study the
effect of statins on outcomes in heart transplant recipients. Methods: We
searched PubMed for all published studies comparing statins with controls
in heart transplant recipients. Outcomes studied included all-cause
mortality and hemodynamically significant / fatal rejection. All studies
reporting these outcomes were included in the pooled analysis. Random
effects model with Mantel-Haenszel method was used to analyze the
outcomes. Results: We identified 9 studies (n = 2062) which compared
outcomes in heart transplant recipients receiving statins (n = 1449) with
that of those not receiving statins (n = 613). Of the 9 studies, 4 were
randomized controlled trials and 5 were retrospective studies. There was
no heterogeneity across the studies (mortality - I2 = 0%, rejection - I2 =
19%). The use of statins was associated with a significant reduction in
all-cause mortality (OR 0.28, 95% CI 0.21-0.37, p < 0.0001). Statins also
significantly decreased hemodynamically significant / fatal rejections (OR
0.41, 95% CI 0.25-0.69, p < 0.0001) Conclusion: Statins provide
significant survival benefit and reduce cardiac allograft rejection in
heart transplant recipients.

Abstract
Background: The American College of Cardiology (ACC) guidelines recommend
three months of anticoagulation (AC) after replacement of the aortic valve
with a bioprosthesis (BP). However, there remains great variability in the
current clinical practice and conflicting results from clinical studies.
To assist clinical decision making, we pooled the existing evidence to
assess whether AC in the setting of a new BP was associated with improved
outcomes and/or greater risk of bleeding. Methods: We searched the PubMed
database from the inception of these databases until April 2015 to
identify original studies (observational studies or clinical trials) that
assessed AC with warfarin in comparison with either aspirin or no
antiplatelet or anticoagulant therapy. We included the studies if their
outcomes included thromboembolism or stroke/transient ischemic attacks
(TIA) and bleeding events. Quality assessment was performed in accordance
with the Newland Ottawa scale and random effects was used to pool the data
from the available studies. I2 testing was done to assess the
heterogeneity of the included studies. Results: After screening through
170 papers, a total of 13 studies (cases=6431, controls=18210) were
included in the final analyses. Use of warfarin use was associated with a
significantly increased risk of overall bleeding (OR= 1.96, 95% CI
1.25-3.08, P<0.0001) or bleeding risk at 3 months (OR= 1.92, 95% CI
1.10-3.34), P<0.0001) compared with aspirin or placebo. With regard to
composite primary outcome variables (risk of venous thromboembolism,
stroke or TIA) at 3 months, no significant difference was seen with
warfarin (OR= 1.13, 95% CI 0.82-1.56, P=0.67). Moreover AC was also not
shown to improve outcomes at time interval >3 months (OR= 1.12, 95% CI
0.80-1.58, P=0.79). Conclusion: Contrary to the current guidelines, a
meta-analysis of prior studies suggests that AC in the setting of an
aortic bioprosthesis significantly increases bleeding risk without a
favorable impact on thromboembolic events. Larger, randomized controlled
studies should be performed to further guide this clinical practice.

Abstract
Introduction: A previous meta-analysis found that pregnancy increases the
risk of structural valve deterioration (SVD) of bioprosthetic valves.
However both homografts and xenografts were included indistinctly in the
analysis. The purpose of this study is to conduct a meta-analysis to
determine if pregnancy independently increases the risk of SVD in women
recipient of homograft and xenograft valves. Methods: We searched MEDLINE,
EMBASE, CINAHL, Web of Knowledge, and Cochrane Library databases for
articles published from inception until May 2015. Only cohort and case
control studies were included. We calculated the relative risk (RR) and
the corresponding 95% confidence interval (CI) of having SVD by pregnancy
status using the DeSirmonian-Laird method. Meta-regression examined the RR
of SVD by age, number of pregnancies and time from valve replacement to
delivery. Results: Our search strategy yielded 23 publications; nine
studies met inclusion criteria. Two studies (75 women) were performed in
recipients of homografts. They were divided in two groups according to
their history of pregnancies, 22 who were pregnant at least once and 53
who never were pregnant. Eight studies (1071 women) assessed SVD in women
recipient of xenografts, including 282 women who had been pregnant and 789
who never were pregnant. Twenty (26.6%) and 341 (31.8%) women recipients
of homografts and xenografts respectively developed SVD. Among the
recipients of xenografts, the RR of having SVD in pregnant women was 1.70;
95% CI 1.26-2.29; p<0.01 (Figure), whereas it was 1.03 (95% CI 0.45-2.33;
p<0.01) in recipients of homografts. None of the factors evaluated in
meta-regression in recipients of xenografts were statistically
significant. Conclusion: Pregnancy does increase the risk of SVD in
recipients of xenografts, but no homografts. Homografts would be a better
option than xenografts in women of childbearing age non suitable for
long-term anticoagulation.

Abstract
Background: Transcatheter Aortic valve replacement (TAVR) has emerged as
new technique for the management of patient with severe Aortic Stenosis
(AS). Stroke is a potential complication associated with the procedure,
when performed via both transfemoral (TF) and transapical approach (TA).
Due to limited data, we performed a comprehensive meta-analysis comparing
30-day and 1-year stroke rates with TAVR performed using TF vs TA
approach. Methods: We searched SCOPUS since inception to July 2014 using
pre-defined criteria. The cerebrovascular event rates and type were
estimated at different time points using standard random effects model.
Results: 5 studies, with total 1956 valves placed, reported 30-day stroke
rates with TA approach, and 9 studies, with 1146 valves, reported stroke
rates with TF approach. No significant difference (p=0.313) was noted with
TA vs TF approach with stroke rates 1.74 (0.61-2.87), 1.52 (0.71-2.33)
respectively (Figure 1, Panel A). Similarly, 4 studies, with total 1657
valves, reported 1-year stroke rates with TA approach, and 8 studies, with
1034 valves, reported stroke using TF approach. Again, no significant
difference (p=0.161) was noted with TA vs TF approach with adjusted stroke
rates 3.78 (1.72-5.85), 3.11 (1.49-4.74) respectively (Figure 1, Panel B).
Conclusion: We did not observe any difference in stroke rates when TAVR is
performed using transapical versus transfemoral approach..

Abstract
Background: Combined use of dual antiplatelet therapy with oral
anticoagulation (OAC) is required in some patients with after coronary
artery stenting or acute coronary syndrome (ACS) Methods: We performed a
meta-analysis of the comparative effects of triple antithrombotic therapy
(TT) vs OAC with single antiplatelet therapy (DT) on all-cause mortality,
stroke, cardiovascular death, myocardial infarction, target vessel
revascularization and major bleeding. We conducted an EMBASE and MEDLINE
search for prospective controlled trials and cohort studies of patients
requiring anticoagulation after coronary stenting Results: We identified 3
prospective controlled studies and 5 cohort studies, which compared TT vs
dual therapy (DT). We identified 4 prospective controlled and 6 cohort
studies with 4564 patients on TT and 1848 on DT with an average follow up
duration of 10.1 months. TT is associated with similar rates of all-cause
mortality, stroke and major bleeding but significantly lower rates of
myocardial infarction compared to DT (mainly OAC plus clopidogrel)
Conclusion: Triple antithrombotic therapy is associated with similar
mortality and bleeding rates but less myocardial infarctions compared with
OAC and single antiplatelet therapy.

Abstract
Background: Dual antiplatelet therapy (DAPT) is recommended for 6-12 month
after drug-eluting stent (DES) implantation to prevent ischemic events and
late stent thrombosis. The optimal duration of DAPT has not been
established Methods: We performed a meta-analysis of the comparative
effects of short- and long- vs standard DAPT duration on adverse
cardiovascular and major bleeding. We conducted an EMBASE and MEDLINE
search for studies in which patients were randomized to treatment with a
different duration of DAPT Results: We identified 5 prospective randomized
studies comparing short- vs standard DAPT and 3 comparing long vs.
standard DAPT duration with a total of 28,343 patients. Short term DAPT
has similar incidence of stent thrombosis, MI and death compared to
standard DAPT whereas major bleeding was significantly lower in short DAPT
therapy. Long term DAPT was associated with lower rates of stent
thrombosis and MI but significantly increased major bleeding and all-cause
mortality compared to standard therapy Conclusion: We found that short
DAPT is safer and as effective as standard DAPT in patients with second
generation DES. Extended DAPT is associated with less ischemic events at
the expense of high bleeding and mortality rates.

Abstract
Introduction: The benefits of optimal medical therapy (OMT) with or
without percutaneous coronary intervention (PCI) or coronary artery bypass
graft (CABG) surgery have been evaluated in patients with Type 2 Diabetes
Mellitus (T2DM) and stable coronary artery disease (CAD) but analyses have
not been stratified by detailed angiographic CAD burden or left
ventricular ejection fraction (LVEF) Methods: A patient-level
meta-analysis was undertaken among T2DM patients enrolled in COURAGE, BARI
2D and FREEDOM to assess the impact of randomization to OMT, PCI + OMT, or
CABG + OMT on a composite end-point of Death/MI/Stroke and stratified by
LVEF (> 50%, < 50%), 1, 2 or 3 vessel disease (VD) (% diameter stenosis >
50%) and presence or absence of proximal left anterior descending (pLAD)
disease. Hazard ratios (HR) for treatment groups were calculated from Cox
regression models including all patients adjusting for trial and
revascularization stratum in BARI 2D. Multivariable adjustment for risk
factors was performed as a sensitivity analysis Results: There were 5,034
patients included in the analysis (BARI 2D: n=2,368, COURAGE: n=766,
FREEDOM: n=1,900) of whom 17% had LVEF < 50%, 29% had pLAD, and 77% had 2
or 3 VD. A total of 1,591 patients were randomized to OMT alone, 2,118 to
PCI + OMT, and 1,325 to CABG + OMT. There were 1,116 events during a
median 4.5 year follow-up. There was no significant effect on outcomes
with OMT vs PCI + OMT irrespective of LVEF, presence/absence of pLAD and
number of VD. By contrast, CABG + OMT significantly reduced the risk of
Death/MI/Stroke in patients with 2 or 3 VD, irrespective of LVEF and
presence/absence of pLAD (see Table). Results were similar with
multivariable adjustment Conclusions: In patients with T2DM and stable
CAD, OMT alone appears to be as effective as PCI + OMT while CABG + OMT
significantly reduces cardiovascular events in those with multivessel CAD,
irrespective of LVEF or presence of pLAD.

Abstract
Introduction: More than 37 million non cardiothoracic operations are
performed in the USA per annum. Single studies have reported that
peri-operative atrial fibrillation (POAF) complicates non-cardiac surgery
in <12% of patients. It is not clear if POAF is associated with adverse
outcomes. Purpose: We conducted a systematic review to determine the
frequency and implications of POAF. Methods: We conducted a literature
search of MEDLINE, Embase, HTA, Cochrane, and Pubmed databases. We defined
POAF as a single episode of AF confirmed by ECG within 30 days of non
cardiothoracic surgery. Inclusion criteria were published manuscripts and
abstracts containing patient level information. We excluded studies which
were not published in English, described cardiothoracic surgery, were
missing patient-level AF data or included patients aged <18 years.
Results: Our search produced 4445 publications, from which 716 abstracts
and 534 manuscripts were identified for review. After applying
inclusion/exclusion criteria, 225 manuscripts were analysed. Combining all
studies, POAF occurred in 18789/650120 patients (2.9%, n=172, median [IQR]
2.2% [0.9-5.8]). Among 37 prospective studies, POAF occurred in 517/10990
patients (4.7%, n=37, 3.23% [1.0-8.8]). AF was prospectively identified
pre-op in 875/26596 (3.3%, n=18, 9.0% [5.5-13.1]) and post-op in 472/14719
(3.2%, n=18, 8.8% [5.5-13.0]). In 135 retrospective studies, POAF occurred
in 18272/639130 patients (2.9% n=135, 2.13 [0.8-4.4]). In retrospective
analyses, AF was pre-existent in 49756/2440489, (2.0%, n=44, 6.7%
[4.3-13.1]) and de novo in 12043/1641875, (0.7%, n=23, 6.0% [1.6-12.3]).
Stratifying by surgery type, POAF was most common in vascular (104/1380,
7.5%), followed by orthopaedic (128/2384, 5.4%), and neurosurgical
(197/4390, 4.5%) patients. Patient outcomes were not systematically
reported: at 1 year, mortality occurred in 927/4136 (22.4%) POAF patients,
compared to 8498/63746 (13.3%) non-POAF patients (n=7). Conclusions: POAF
occurred in 2.9% of 650120 patients and was associated with a 68% increase
in mortality. Prospective research is required to determine whether any
specific intervention(s) in POAF patients will improve outcomes.

Abstract
Introduction: Atrial fibrillation (AF) is common after coronary artery
bypass grafting (CABG). Ranolazine is a novel drug used in the treatment
of angina, which also has antiarrhythmic properties. Recent studies
demonstrated the benefit of ranolazine in preventing post-operative AF
(POAF) in patients undergoing CABG. Hypothesis: To assess the role of
ranolazine in preventing POAF in patients undergoing CABG surgery.
Methods: We performed comprehensive search of PubMed, MEDLINE, and
Cochrane library database on the study assessing the effectiveness of
ranolazine in preventing POAF by comparing it with standard therapy.
Meta-analysis was performed by fixed effect model by entering POAF events
and the total population from each study. Data are expressed as Odds ratio
(OR) with 95% confidence interval (CI). Results: A total of three studies
with 628 patients (259 pts in ranolazine group, 369 pts in standard
therapy group) were included in the meta-analysis. In pooled analysis,
ranolazine was associated with 54% reduction in post-operative AF events
compared to standard therapy [odds ratio = 0.46 (0.31, 0.70), P<0.001].
The number needed to be treated was 7.14. In one of the study, more
patients in ranolazine group (52.2%) had symptomatic hypotension three
days after the surgery. Conclusions: Ranolazine may prove beneficial in
the prevention of POAF following CABG. However, because of small number of
studies further research with large randomized clinical trial is warranted
to determine specific dose and duration of ranolazine therapy.

Abstract
Background: Atrial fibrillation (AF) is a known complication of orthotopic
heart transplantation (OHT). However, post-OHT AF is yet to be well
characterized as studies report diverse data on the incidence rate and
clinical characteristics of this arrhythmia. This study provides a review
and meta-analysis of the existing evidences on the incidence rate, time of
onset and association with allograft rejection of post-OHT AF. Methods: An
extensive literature search was performed on PubMed, MEDLINE and EMBASE
databases (from 1990 to August 2014) and reference lists of selected
articles for studies on the incidence of atrial fibrillation in OHT
patients. Post OHT arrhythmia incidence data along with population
characteristics were collected and pooled prevalence rate and associated
95% confidence intervals (CIs) were calculated. Results: Ten prospective
studies with 3,852 patients undergoing OHT were included in the primary
meta-analysis. The pooled prevalence of AF across studies was 5.4% (95% CI
7.0-10.1). AF was the most common early arrhythmia; 74% (95% CI 65-83) of
the reported AF episodes were observed in <30 days of OHT. The pooled
prevalence of AF was much higher with allograft rejection (41.5%, 95% CI
32-52, p<0.001). Additionally, two studies reported lower incidence of AF
following OHT compared to the AF-incidence after other cardiac surgeries
such as MAZE and double- lung transplantation, despite pulmonary vein
isolation in both groups (relative OR 0.25, 95% CI 0.07-0.56), which they
attributed to the antiarrhythmic benefit of cardiac denervation in the
transplanted heart. Conclusion: In heart transplant recipients atrial
fibrillation is uncommon; mostly seen in the early post-operative period
and often in the presence of graft rejection. Of note, cardiac autonomic
denervation may have a protective antiarrhythmic effect in the
post-operative setting of orthotopic heart transplantation.

Abstract
Objective In animal models, G-CSF based progenitor cell mobilization
combined with a DPP4 inhibitor leads to increased homing of bone marrow
derived progenitor cells to the injured myocardium via the SDF1/CXCR4 axis
resulting in improved ejection fraction and survival after acute
myocardial infarction (AMI). Research design and methods After successful
revascularization in AMI, 174 patients were randomized 1:1 in a
multi-centre, prospective, placebo-controlled, parallel group, double
blind, phase III efficacy and safety trial to treatment with G-CSF and
Sitagliptin (GS) or placebo. Diabetic and non-diabetic patients were
included in our trial. The primary efficacy endpoint hierarchically
combined global left and right ventricular ejection fraction changes from
baseline to 6 months of follow-up (DELTA<inf>LVEF</inf>,
DELTA<inf>RVEF</inf>), as determined by cardiac MRI. Results At follow-up
DELTA<inf>LVEF</inf> as well as DELTA<inf>RVEF</inf> did not differ
between the GS and placebo group. Patients in the placebo group had a
similar risk for a major adverse cardiac event within 12 months of
follow-up as compared to patients under GS. Conclusion Progenitor cell
therapy comprising the use of G-CSF and Sitagliptin after successfully
revascularized acute myocardial infarction fails to show a beneficial
effect on cardiac function and clinical events after 12 months. (EudraCT:

Abstract
To explore the protective effects of Danhong injection against cerebral
damage during on-pump coronary artery bypass graft surgery and its
mechanism. Methods. Fifty patients scheduled for on-pump CABG surgery were
randomly divided into Danhong injection group (group D) and control group
(group C). Group D was given Danhong injection while group C was given the
same volume of normal saline when the artery was cut open. Jugular bulb
blood right before the operation began (T1), when body temperature
rewarming to 36degreeC (T2), 30 min after the termination of
cardiopulmonary bypass (T3), and 6 hrs after the termination of CPB (T4)
was collected. The superoxide dismutase activity by using xanthine oxidase
method and concentration determination of malondialdehyde were examined.
Results. In group C, SOD activity was less at T2-T4 than at T1. It was
also less active comparatively in group D at T2-T4. The MDA concentration
increased in both groups but was more obvious in group C. Levels of TNF-,
IL-6, IL-8, and IL-10 increased in both groups C and D at T3 and T4,
compared to T1. Conclusions. Danhong injection shows significant
protective effects against cerebral damage during on-pump coronary artery
bypass graft surgery.

Abstract
Background Radial access for percutaneous coronary intervention is
associated with lower rates of access site complications and bleeding.
However, elderly patients have more complex vascular anatomy and radial
access may be more challenging in this population. There remains
uncertainty regarding the role of radial access in elderly patients
undergoing cardiac catheterization. Methods and Results The RIVAL trial
randomized patients with acute coronary syndromes undergoing cardiac
catheterization to radial versus femoral access. In this analysis, the
rates of access site complications and access site cross-over were
compared across different age groups. Among the 7,021 patients, 1035 (15%)
were >75 years of age. Across all age categories, radial access was
consistently associated with higher rates of access site cross over and
lower rates of major access site complications, with no significant
interaction between age and access site. Radial access was associated with
lower rates of major vascular access site complications in patients >75
years of age (3.6% vs 6.6%; P =.03) and in patients <75 years of age (1.0%
vs 3.2%; P <.001; P value for interaction =.2). The rates of access site
crossover were higher with radial access among patients >75 (12.5% vs
2.6%; P <.001) and <75 (6.7% vs 1.9%; P <.001; P value for interaction
=.9). There were no significant differences in the primary composite
outcome (death, myocardial infarction, stroke or non coronary artery
bypass graft major bleeding) or its individual components in either age
group. In patients >75 years of age undergoing primary percutaneous
coronary intervention, there was no significant difference in procedure
time (120 vs 115 minutes; P =.3). Conclusions Consistent with the overall
RIVAL trial population, elderly patients undergoing cardiac
catheterization have lower rates of major bleeding or access site
complications and higher rates of access site crossover with radial access
compared to femoral access.

Abstract
Background: Although remote ischemic preconditioning (RIPC) has emerged as
an attractive strategy to reduce cardiac injury in patients undergoing
diverse cardiac surgical procedures, it is unclear whether RIPC has
protective effects in patients undergoing aortic valve replacement surgery
without coronary artery bypass grafting (CABG). Methods: Hence, 100 adult
patients undergoing elective aortic valve replacement for aortic valve
stenosis, without combined surgery with CABG, were prospectively randomly
assigned in a 1:1 ratio to either the RIPC group or the control group. The
RIPC group underwent three cycles of 5-min inflation to 200. mmHg and
5-min deflation of an automated upper-arm cuff inflator after induction of
anesthesia. The control group had a deflated cuff placed on upper arm for
30. min. The primary endpoint was 72-h area under curve (AUC) for troponin
I (cTnI). Secondary endpoints were 72-h AUC for creatine kinase-MB
isoenzyme (CK-MB) release, incidence of acute kidney injury, extubation
time, length of stay in intensive care unit, and simplified acute
physiology score (SAPS II). Results: There were no significant differences
in cTnI AUC [195. +/-. 190 arbitrary units (a.u.) in RIPC group vs. 169.
+/-. 117 a.u. in the control group; p = 0.41] and CK-MB AUC between
groups. None of the other secondary endpoints differed between groups.
Acute kidney injury occurred in 12 patients (24.5%) in the control group
and in 13 (26.0%) in the RIPC group (p = 0.86). Conclusions: RIPC did not
exhibit significant cardiac or kidney protective effects in patients
undergoing aortic valve replacement surgery without CABG.

The Safety and Efficacy of Absorb Bioresorbable Vascular Scaffold: A
Systematic Review.

Abstract
Bioresorbable stents are novel devices designed to overcome the long-term
limitations of permanent stent implantation. The Absorb bioresorbable
vascular scaffold (BVS; Abbott Vascular, Santa Clara, CA) was the first
bioresorbable stent with Conformite Europeenne mark approval in coronary
vessels and has been the subject of multiple clinical studies. Despite its
potential advantages, the safety and efficacy of BVS remain unclear. To
address this, we conducted a systematic review to examine the safety and
efficacy of BVS. The MEDLINE, Embase, Current Index to Nursing & Allied
Health Literature (CINAHL), Cochrane, and Science Citation Index Expanded
(SCIE) databases were searched for studies examining BVS safety and
efficacy. Our search was restricted to studies published in English or
French. Outcomes of interest include cardiac death, myocardial infarction,
target-lesion revascularization, restenosis, and composite endpoints.
Eleven studies met our inclusion criteria (n = 2990), which included 1
randomized controlled trial and 10 cohort studies (2 controlled). These
studies varied in size (11-1189) and follow-up duration (1-60 months). The
incidence of major adverse cardiac events ranged from 2.6% to 15.5%, with
no statistically significant difference between BVS and control in studies
that included a comparison group. Although available data are limited,
current evidence is promising and suggests that the use of BVS is not
associated with a significant increase in major cardiac events in the
short term. Numerous randomized controlled trials are currently in
progress that will further improve our understanding of the safety and
efficacy of this device.

Background: Video-assisted thoracic surgery (VATS) has been shown to
effectively reduce postoperative pain, enhance mobilization of the
patients, shorten in-hospital length of stay, and minimize postoperative
morbidity rates. The aim of this prospective study is to evaluate
neuroendocrine and respiratory parameters as stress markers in cancer
patients who underwent lung wedge resections, using both mini
muscle-sparing thoracotomy and VATS approach. Methods: The patients were
randomly allocated into two groups: Group A (n=30) involved patients who
were operated on using the VATS approach, while in group B (n=30), the
mini muscle-sparing thoracotomy approach was used. Neuroendocrine and
biological variables assessed included blood glucose levels, Creactive
protein (CRP) levels, cortisol, epinephrine, and adrenocorticotropic
hormone (ACTH) levels. Arterial oxygen (Pao<inf>2</inf>) and carbon
dioxide (Paco<inf>2</inf>) partial pressure were also evaluated. All
parameters were measured at the following time points: 24 hours
preoperatively (T<inf>1</inf>), 4 hours (T<inf>2</inf>), 24 hours
(T<inf>3</inf>), 48 hours (T<inf>4</inf>), and 72 hours (T<inf>5</inf>),
after the procedure. Results: Pao2 levels were significantly higher 4 and
24 hours postoperatively in group A vs group B, respectively
(T<inf>2</inf>: 94.3 vs 77.9 mmHg, P=0.015, T<inf>3</inf>: 96.4 vs 88.7
mmHg, P=0.034). Blood glucose (T<inf>2</inf>: 148 vs 163 mg/dL, P=0.045,
T3: 133 vs 159 mg/dL, P=0.009) and CRP values (T<inf>2</inf>: 1.6 vs 2.5
mg/dL, P=0.024, T<inf>3</inf>: 1.5 vs 2.1 mg/dL, P=0.044) were found
increased in both groups 4 and 24 hours after the procedure. However,
their levels were significantly lower in the VATS group of patients. ACTH
and cortisol values were elevated immediately after the operation and
became normal after 48 hours in both groups, without significant
difference. Postoperative epinephrine levels measured in group A vs group
B, respectively, (T<inf>2</inf>: 78.9 vs 115.6 ng/L, P=0.007,
T<inf>3</inf>: 83.4 vs 122.5 ng/L, P=0.012, T<inf>4</inf>: 67.4 vs 102.6
ng/L, P=0.021). The levels were significantly higher in group B.
Conclusion: This study confirmed that minimally invasive thoracic surgery,
by means of VATS, significantly reduces the acute-phase response and
surgical stress, while enables better postoperative oxygenation.

Abstract
Aims: Treatment of bare metal in-stent restenosis with the
paclitaxel-coated balloon catheter based on the PACCOCATH technology has
yielded superior six-month angiographic and one-year clinical results
compared to a paclitaxel-eluting stent. The three-year clinical follow-up
is presented. Methods and results: One hundred and thirty-one patients
with coronary bare metal in-stent restenosis (>70%, length: <22 mm, vessel
diameter: 2.5-3.5 mm) were randomly treated with the paclitaxel-coated
balloon (DCB) (3 mug/mm²) or a paclitaxel-eluting stent (DES).
Clinical follow-up information was requested from the patients and from
their physicians. Quantitative angiographic and demographic baseline data
were statistically not different between the groups. Per
intention-to-treat analysis at 12 months, the lesion-related rates of
major adverse cardiac events were 7.6% and 16.9% (p=0.11) while at 36
months the respective numbers were 9.1% and 18.5% (p=0.14). These
differences were primarily due to reduced target lesion revascularisation
(TLR) in DCB 4/66 (6.2%) compared to DES patients 10/65 (15.4%) (p=0.10).
From 12 to 36 months, 1/65 (1.5%) DCB patients experienced a myocardial
infarction while neither TLR nor death occurred in any study patient in
either group during that period. Conclusions: The six-month superiority of
the paclitaxel-coated balloon compared to the paclitaxel-eluting stent in
the treatment of bare metal coronary in-stent restenosis persisted
throughout the three-year clinical follow-up period indicating stability
of the lesions treated.

Abstract
Objective: Postoperative atrial fibrillation is the most commonly observed
arrythmia following cardiac surgery. Both atrial fibrillation and
preoperative anemia hve been related to high rate of mortality and
postoperative morbidity. In this systematic review and meta-analysis, we
aimed to analyze whether levels of preoperative hemoglobin or hematocrit
were useful biomarkers for development of postoperative atrial
fibrillation after cardiac surgery or not. Methodology: The literature
screening was performed from PubMed database without any date limitation.
All patients who underwent open cardiac surgery procedures were
considered. Outcome measures included the association between preoperative
levels of hemoglobin/hematocrit and atrial fibrillation after cardiac
surgery. The results of trials were evaluated with random or fixed effect
model according to the heterogeniety. The statistical evaluation was
performed by using Open Meta Analyst programme. Results: A total of 9948
articles were found after database searching. 17 articles were included in
metaanalysis consisting of 5934 patients who fulfilled inclusion criteria.
The rate of postoperative atrial fibrillation was 35.6% (2114 cases out of
5934). Effect size was observed as heterogenous for studies including
hematocrit (Q(df): 30.76, p <0.001, I²: 73.99%). However, it
was not observed as heterogeneous for studies including hemoglobin (Q(df):
11.10, p: 0.26, I²:18.96%). Analysis results of studies
including hematocrit according to random effect model were SMD: 0.013, 95%
CI -0.21-0.18 and p: 0.89 (p > 0.05). And analysis results of studies
including hemoglobin according to fixed effect model were SMD: 0.172, 95%
CI -0.23-0.11 and p < 0.001. Conclusion: The results of quantitative
analysis showed that preoperative hemoglobin is associated with
development of atrial fibrillation, but hematocrit is not. However, more
studies may be required including both hemoglobin and hematocrit in the
same trials to clearly establish this association.

Abstract
Background and Aims: hypotensive anesthesia is preferred in craniotomy.
Current study was conducted to evaluate the effects of oral clonidine
premedication upon hemodynamic status, dural tightness and quality of
anesthesia using 3 point scoring system in patients scheduled for
craniotomy under general anesthesia. Methodology: Amongst twenty two
selected cases they were grouped equally in this randomized single - blind
comparative study. Group A and B patients received sugar tablet and oral
clonidine 3 mug/kg as a premedication respectively. Monitoring of
hemodynamic variables like heart rate, systolic arterial pressure,
diastolic arterial pressure, mean arterial pressure, SpO<inf>2</inf>,
E<inf>T</inf>CO<inf>2</inf> and dural tightness were performed. Results:
Diastolic arterial pressure was significantly low in Group B during
positioning, performing burr hole and during dura incision. Mean arterial
pressure was highly significant for Group B during positioning. Heart rate
change was significantly high for Group B during burr hole. Regarding
dural tightness, 10 patients in Group B and 6 in Group A had no dural
swelling. 1 patient in Group B and 5 patients in Group A had minimal
swelling and surgery continued. Once all results b being assessed using
'Three point scoring system', it became highly significant in Group B with
respect to Group A. Conclusion: Oral clonidine premedication provides
optimal hemodynamic stability and good neuro-surgical comprising heart
rate, mean arterial pressure and dural tightness. 'Three point scoring
system' seems to be an effective tool for intra-operative monitoring of
patients undergoing supra-tentorial craniotomy.

Abstract
Background: Levosimendan a calcium ion sensitizer improves both systolic
and diastolic functions. This novel lusitropic drug has predictable
antiischemic properties which are mediated via the opening of
mitochondrial adenosine triphosphate-sensitive potassium channels. This
action of levosimendan is beneficial in cardiac surgical patients as it
improves myocardial contractility, decreases systemic vascular resistance
(SVR), and increases cardiac index (CI) and is thought to be
cardioprotective. We decided to study whether levosimendan has any impact
on the outcomes such as the duration of ventilation, the length of
Intensive Care Unit (ICU) stay, and the hospital stay when compared with
the nitroglycerine (NTG), which is the current standard of care at our
center. Materials and Methods: Forty-seven patients undergoing elective
coronary artery bypass surgery were randomly assigned to two groups
receiving either levosimendan or NTG. The medications were started before
starting surgery and continued until 24 h in the postoperative period.
Baseline hemodynamic parameters were evaluated before beginning of the
operation and then postoperatively at 3 different time intervals.
N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) levels
were also measured in both groups. Results: In comparison to the NTG
group, the duration of ventilation and length of ICU stay were
significantly less in levosimendan group (P < 0.05, P = 0.02). NT-proBNP
level analysis showed a slow rising pattern in both groups and a
statistically significant rise in the levels was observed in NTG group (P
= 0.03, P = 0.02) in postoperative period when compared to levosimendan
group of patients. Conclusion: Levosimendan treatment in patients
undergoing surgical revascularization resulted in improved CI, decreased
SVR and lower heart rate. And, thereby the duration of ventilation and
length of ICU stay were significantly less in this group of patients when
compared with NTG group.

Abstract
Context: We hypothesized that reduced oropharyngolaryngeal stimulation
with video laryngoscopes would attenuate hemodynamic response to
laryngoscopy and intubation. Aim: Comparison of hemodynamic response to
laryngoscopy and intubation with video laryngoscopes and Macintosh (MC)
laryngoscope. Setting and Design: Superspecialty tertiary care public
hospital; prospective, randomized control study. Methods: Sixty adult
patients undergoing elective coronary artery bypass grafting (CABG) were
randomly allocated to three groups of 20 each: MC, McGrath (MG), and
Truview (TV). Hemodynamic parameters were serially recorded before and
after intubation. Laryngoscopic grade, laryngoscopy, and tracheal
intubation time, ST segment changes, and intra-/post-operative
complications were also recorded and compared between groups. Statistical
Analysis: SPSS version 17 was used, and appropriate tests applied. P <
0.05 was considered significant. Results: Heart rate and diastolic
arterial pressure increased at 0 and 1 min of intubation in all the three
groups (P < 0.05) while mean arterial pressure increased at 0 min in the
MG and TV groups and at 1 min in all three groups (P < 0.05). A
significant increase in systolic arterial pressure was only observed in TV
group at 1 min (P < 0.05). These hemodynamic parameters returned to
baseline by 3 min of intubation in all the groups. The intergroup
comparisons of all hemodynamic parameters were not significant at any time
of observation. Highest intubation difficulty score was observed with MC
(2.16 +/- 1.86) as compared with MG (0.55 +/- 0.88) and TV (0.42 +/- 0.83)
groups (P = 0.003 and P = 0.001, respectively). However, duration of
laryngoscopy and intubation was significantly less in MC (36.68 +/- 16.15
s) as compared with MG (75.25 +/- 30.94 s) and TV (60.47 +/- 27.45 s)
groups (P = 0.000 and 0.003, respectively). Conclusions: Video
laryngoscopes did not demonstrate any advantage in terms of hemodynamic
response in patients with normal airway undergoing CABG.

Abstract
Context: Frequent incidence of early postoperative memory impairment
(POMI) after cardiac surgery remains a concern because of associated
morbidity, impaired quality of life, and increased health care cost. Aim:
To assess the effect of preoperative statin therapy on POMI in patients
undergoing off-pump coronary artery bypass (OPCAB) surgery. Setting and
Design: Prospective observational study in a tertiary level hospital.
Methods: Sixty patients aged 45-65 years undergoing OPCAB surgery were
allocated into two groups of 30 each. Group A patients were receiving
statin and Group B patients were not receiving statins. All patients
underwent memory function assessment preoperatively after admission to
hospital and on the 6 ^th postoperative day using postgraduate
institute memory scale. Statistical Analysis: Appropriate tests were
applied with SPSS 20 to compare both groups. The value P < 0.05 was
considered statistically significant. Multiple regression analysis was
performed with confounding factors to determine the effect on memory
impairment. Results: Patients in Group A showed significant postoperative
deterioration in 6 of the 10 functions and in Group B showed deterioration
in 9 of 10 functions tested compared to preoperative scores. Intergroup
comparison detected less POMI in Group A compared to Group B and was
statistically significant in 8 memory functions. Multiple regression
analysis detected statin as an independent factor in preventing memory
impairment. Conclusions: Preoperative statin therapy attenuates the early
POMI in patients undergoing OPCAB. Future long-term studies will define
the efficacy of statin on POMI.

Abstract
Remote ischemic conditioning (RIC) using transient limb
ischemia/reperfusion has been reported to reduce perioperative myocardial
injury in patients undergoing coronary artery bypass grafting and/or valve
surgery. The role of intravenous glyceryl trinitrate (GTN) therapy
administered during cardiac surgery as a cardioprotective agent and
whether it interferes with RIC cardioprotection is not clear and is
investigated in the ERIC-GTN trial (http://www.clinicaltrials.gov:
NCT01864252). The ERIC-GTN trial is a single-site, double-blind,
randomized, placebo-controlled study. Consenting adult patients (age > 18
years) undergoing elective coronary artery bypass grafting +/- valve
surgery with blood cardioplegia will be eligible for inclusion. Two
hundred sixty patients will be randomized to 1 of 4 treatment groups
following anesthetic induction: (1) RIC alone, a RIC protocol comprising
three 5-minute cycles of simultaneous upper-arm and thigh cuff
inflation/deflation followed by an intravenous (IV) placebo infusion; (2)
GTN alone, a simulated sham RIC protocol followed by an IV GTN infusion;
(3) RIC + GTN, a RIC protocol followed by an IV GTN infusion; and (4)
neither RIC nor GTN, a sham RIC protocol followed by IV placebo infusion.
The primary endpoint will be perioperative myocardial injury as quantified
by the 72-hour area-under-the-curve serum high-sensitivity troponin T. The
ERIC-GTN trial will determine whether intraoperative GTN therapy is
cardioprotective during cardiac surgery and whether it affects RIC
cardioprotection.

Abstract
INTRODUCTION: High surgical risk patients with severe symptomatic aortic
stenosis (SSAS) are currently being managed with transcatheter aortic
valve implantation (TAVI). Limitations of this procedure include increased
cost, resultant paravalvular leakage, coronary occlusion, and possible
aortic rupture. A new surgical option for this group has emerged with the
advent of surgical sutureless aortic valve replacement (SU-AVR). This
study reviews the postoperative outcomes of SU-AVR in comparison with
TAVI. METHODS: A systematic review was conducted, identifying all relevant
studies with comparative data on SU-AVR vs TAVI. The primary endpoint was
the incidence of postoperative mortality and paravalvular leaks. Other
postoperative outcomes measured were the incidence of postoperative atrial
fibrillation (AF), stroke, acute myocardial infarction (AMI), and acute
renal failure (ARF). Statistical analysis was done using SPSS to calculate
odds ratios and 95% confidence intervals. RESULTS: Five studies were
quantitatively assessed and included for meta-analysis of 2 prospective
and 3 retrospective studies. There 303 SU-AVR patients and 417 TAVI
patients. The SU-AVR was associated with reduced rates of postoperative
mortality (odds ratio [OR] 0.19; 95% CI, 0.07-0.57) and paravalvular leaks
(OR 0.12; 95% CI, 0.07-0.21) when compared with TAVI. There were no
significant differences between SU-AVR and TAVI for the occurrence of
postoperative AF (OR 1.05; 95% CI, 0.59-1.89), stroke (OR 0.34; 95% CI,
0.09-1.3), AMI (OR 0.37; 95% CI, 0.04-3.3), and ARF (OR 0.74; 95% CI,
0.29-1.9). CONCLUSIONS: Surgical sutureless aortic valve replacement is a
valid alternative to TAVI in high risk surgical patients because it is
associated with lower incidence of postoperative mortality and
paravalvular leaks.

Title
Steroids In caRdiac Surgery (SIRS) trial: acute kidney injury substudy
protocol of an international randomised controlled trial.
Source
BMJ open. 4 (3) (pp e004842), 2014. Date of Publication: 2014.
Abstract
INTRODUCTION: Steroids In caRdiac Surgery trial (SIRS) is a large
international randomised controlled trial of methylprednisolone or placebo
in patients undergoing cardiac surgery with the use of a cardiopulmonary
bypass pump. At the time of surgery, compared with placebo,
methylprednisolone divided into two intravenous doses of 250 mg each may
reduce the risk of postoperative acute kidney injury (AKI).
METHODS AND ANALYSIS: With respect to the study schedule, over 7000
substudy eligible patients from 81 centres in 18 countries were randomised
in December 2013. The authors will use a logistic regression to estimate
the adjusted OR of methylprednisolone versus placebo on the primary
outcome of AKI in the 14 days following surgery (a postoperative increase
in serum creatinine of >50%, or >26.5 mumol/L, from the preoperative
value). The stage of AKI will also be considered, as will the outcome of
AKI in those with and without preoperative chronic kidney disease. After
receipt of grant funding, the authors began to record additional
perioperative serum creatinine measurements in consecutive patients
enrolled at substudy participating centres, and patients were invited to
enroll in a 6-month serum creatinine collection. In these trial
subpopulations, the authors will consider the outcome of AKI defined in
alternate ways, and the outcome of a 6-month change in kidney function
from the preoperative value.
ETHICS AND DISSEMINATION: The authors were competitively awarded a grant
from the Canadian Institutes of Health Research for this SIRS AKI
substudy. Ethics approval was obtained for additional serum creatinine
recordings in consecutive patients enrolled at participating centres. The
additional kidney data collection first began for patients enrolled after
1 March 2012. In patients who provided consent, the last 6-month kidney
outcome data will be collected in 2014. The results will be reported no
later than 2015.

Abstract
BACKGROUND: Although acute cellular rejection after heart transplantation
(HTX) can be controlled by full-dose calcineurin inhibitor (CNI)-based
immunosuppressive regimens, cardiac allograft vasculopathy (CAV),
nephrotoxicity, and malignancy remain ongoing problems. To evaluate the
potential beneficial effects of sirolimus and CNI reduction, we compared
de novo low-dose tacrolimus and sirolimus with standard tacrolimus and
mycophenolate mofetil (MMF)-based immunosuppression after HTX.
METHODS: We analyzed a long-term follow-up cohort of 126 patients who
underwent HTX during the period 1998-2005 and received either de novo
low-dose tacrolimus/sirolimus (lowTAC/SIR; n = 61) or full-dose
tacrolimus/MMF (TAC/MMF; n = 64).
RESULTS: Freedom from treatment switch was less in the low TAC/SIR group
than in the TAC/MMF group (51.7% vs 73.0%, p = 0.038) 8 years after HTX.
Freedom from acute rejection was 90.6% in the low TAC/SIR group vs 80.3%
in the TAC/MMF group (p = 0.100). There was no difference in freedom from
International Society for Heart and Lung Transplantation CAV grade > 1
(55.4% vs 60.0%, p = 0.922), time until CAV diagnosis (4.2 +/- 2.0 years
vs 3.2 +/- 2.4 years, p = 0.087), and CAV severity (p = 0.618). The
benefit of reduced early maximum creatinine for low TAC/SIR treatment (1.8
+/- 0.9 mg/dl vs 2.4 +/- 1.1 mg/dl in TAC/MMF group, p < 0.001) did not
continue 5 years and 8 years after HTX (1.4 +/- 0.4 mg/dl vs 1.7 +/- 1.2
mg/dl, p = 0.333, and 1.6 +/- 1.1 mg/dl vs 1.6 +/- 0.8 mg/dl, p = 0.957).
The trend for superior survival at 5 years with low TAC/SIR treatment
(93.1% vs 81.3% in TAC/MMF group, p = 0.051) could not be confirmed after
8 years (84.7% vs 75.0%, p = 0.138). Multivariate analysis at 8 years did
not reveal any benefit of low TAC/SIR treatment.
CONCLUSIONS: Reduction of de novo CNI did not result in superior long-term
renal function. Low-dose mechanistic target of rapamycin inhibition did
not achieve any benefit in CAV prevention compared with full-dose TAC/MMF
after HTX.

Title
Exercise training improves ambulatory blood pressure but not arterial
stiffness in heart transplant recipients.

of the International Society for Heart Transplantation. 34 (5) (pp
693-700), 2015. Date of Publication: 01 May 2015.
Abstract
BACKGROUND: Hypertension is the most prevalent comorbidity after heart
transplantation (HT). Exercise training (ET) is widely recommended as a
key non-pharmacologic intervention for the prevention and management of
hypertension, but its effects on ambulatory blood pressure (ABP) and some
mechanisms involved in the pathophysiology of hypertension have not been
studied in this population. The primary purpose of this study was to
investigate the effects of ET on ABP and arterial stiffness of HT
recipients.
METHODS: 40 HT patients, randomized to ET (n = 31) or a control group (n =
9) underwent a maximal graded exercise test, 24-hour ABP monitoring, and
carotid-femoral pulse wave velocity (PWV) assessment before the
intervention and at a 12-week follow-up assessment. The ET program was
performed thrice-weekly and consisted primarily of endurance exercise (40
minutes) at ~70% of maximum oxygen uptake (Vo2MAX).
RESULTS: The ET group had reduced 24-hour (4.0 +/- 1.4 mm Hg, p < 0.01)
and daytime (4.8 +/- 1.6 mm Hg, p < 0.01) systolic ABP, and 24-hour (7.0
+/- 1.4 mm Hg, p < 0.001) daytime (7.5 +/- 1.6 mm Hg, p < 0.001) and
nighttime (5.9 +/- 1.5 mm Hg, p < 0.001) diastolic ABP after the
intervention. The ET group also had improved Vo2MAX (9.7% +/- 2.6%, p <
0.001) after the intervention. However, PWV did not change after ET. No
variable was changed in the control group after the intervention.
CONCLUSIONS: The 12-week ET program was effective for reducing ABP but not
PWV in heart transplant recipients. This result suggests that endurance ET
may be a tool to counteract hypertension in this high-risk population.

Title
Complete versus culprit-only revascularization in patients with
multi-vessel disease undergoing primary percutaneous coronary
intervention: A meta-analysis of randomized trials.
Source
International journal of cardiology. 186 (pp 98-103), 2015. Date of
Publication: 2015.
Abstract
BACKGROUND: The best approach for revascularization of multi-vessel
coronary disease in patients with ST-elevation myocardial infarction
(STEMI) undergoing primary percutaneous coronary intervention (PCI) is
controversial.
METHODS: We searched the Medline and Web of Science databases, the
Cochrane Register of Controlled Trials, and major conference proceedings
for clinical trials that randomized STEMI patients with multi-vessel
disease to a complete versus culprit-only revascularization strategy.
Random effects summary risk ratios (RR) were constructed using a
DerSimonian-Laird model.
RESULTS: A total of 6 trials met our selection criteria, which yielded
1,190 patients. The mean follow-up duration was 20.5 months. The incidence
of major adverse cardiac events was significantly reduced in the complete
revascularization group versus the culprit-only revascularization group
(RR 0.57, 95% confidence interval (CI) 0.41-0.78, p < 0.001). This was due
to a lower risk of urgent revascularization with complete
revascularization (RR 0.55, 95% CI 0.35-0.86, p = 0.01). A non-significant
reduction was observed with complete versus culprit-only revascularization
for the combined outcome of mortality or myocardial infarction (RR 0.56,
95% CI 0.30-1.04, p = 0.06).
CONCLUSION: Complete revascularization of significant coronary lesions at
the time of primary PCI in patients with STEMI and multi-vessel disease
was associated with better outcomes. This was primarily due to a reduction
in the need for urgent revascularization. Larger trials are needed to
determine if complete revascularization reduces death or myocardial
infarction.
