Abstract
Purpose: Colloids are administered to more patients than crystalloids,
although recent evidence suggests that colloids may possibly be harmful in
some patients. The European Society of Intensive Care Medicine therefore
assembled a task force to compile consensus recommendations based on the
current best evidence for the safety and efficacy of the currently most
frequently used colloids-hydroxyethyl starches (HES), gelatins and human
albumin. Methods: Meta-analyses, systematic reviews and clinical studies
of colloid use were evaluated for the treatment of volume depletion in
mixed intensive care unit (ICU), cardiac surgery, head injury, sepsis and
organ donor patients. Clinical endpoints included mortality, kidney
function and bleeding. The relevance of concentration and dosage was also
assessed. Publications from 1960 until May 2011 were included. The quality
of available evidence and strength of recommendations were based on the
Grading of Recommendations Assessment, Development, and Evaluation (GRADE)
approach. Recommendations and conclusions: We recommend not to use HES
with molecular weight >=200 kDa and/or degree of substitution >0.4 in
patients with severe sepsis or risk of acute kidney injury and suggest not
to use 6% HES 130/0.4 or gelatin in these populations. We recommend not to
use colloids in patients with head injury and not to administer gelatins
and HES in organ donors. We suggest not to use hyperoncotic solutions for
fluid resuscitation. We conclude and recommend that any new colloid should
be introduced into clinical practice only after its patient-important
safety parameters are established. Copyright jointly held by Springer and

Abstract
Background and objectives Treatment of dilutional coagulopathy by
transfusing fresh frozen plasma (FFP) remains sub-optimal. We hypothesized
that partial replacement of transfused FFP by fibrinogen concentrate
results in improved coagulant activity and haemostasis. This was tested in
a controlled clinical intervention trial with patients experiencing
massive bleeding during major surgery. Methods Patients undergoing major
elective surgery were treated according to current protocols. When
transfusion with FFP was required, patients were randomized as follows:
group A received 4units FFP and group B received 2units FFP plus 2g
fibrinogen concentrate. Blood samples were taken before and after the
intervention. Analysts were blinded to the treatment type. Results Group A
(B) consisted of 21 (22) patients, in 16 (17) of whom bleeding stopped
after intervention. Plasma fibrinogen increased significantly more in
group B (057g/l) than in group A (005g/l). However, levels of prothrombin
and factors VIII, IX and X increased more in group A than in group B.
Rotational thromboelastometry (ROTEM) of whole blood and plasma revealed
improved fibrin clot formation in group B but not in group A. Thrombin
generation [calibrated automated thrombogram (CAT)] in plasma increased
more in group A. Principal parameters determining whole-blood
thromboelastometry were the fibrinogen level and platelet count. In vitro
addition of fibrinogen and prothrombin complex concentrate to
pre-intervention samples restored both ROTEM and CAT parameters.
Conclusions Partial replacement of transfused FFP by fibrinogen increases
fibrin clot formation at the expense of less improved thrombin generation.
Coagulation factors other than fibrinogen alone are required for full
restoration of haemostasis. 2011 International Society of Blood

Abstract
BACKGROUND: The primary care evaluation of chest pain represents a
significant diagnostic challenge. OBJECTIVE: To determine if electronic
alerts to physicians can improve the quality and safety of chest pain
evaluations. DESIGN AND PARTICIPANTS: Randomized, controlled trial
conducted between November 2008 and January 2010 among 292 primary care
clinicians caring for 7,083 adult patients with chest pain and no history
of cardiovascular disease. INTERVENTION: Clinicians received alerts within
the electronic health record during office visits for chest pain. One
alert recommended performance of an electrocardiogram and administration
of aspirin for high risk patients (FraminghamRisk Score (FRS)=10%), and a
second alert recommended against performance of cardiac stress testing for
low risk patients (FRS<10%). MAIN MEASURES: The primary outcomes included
performance of an electrocardiogram and administration of aspirin therapy
for high risk patients; and avoidance of cardiac stress testing for low
risk patients. KEY RESULTS: The majority (81%) of patients with chest pain
were classified as low risk. High risk patients were more likely than low
risk patients to be evaluated in the emergency department (11% versus 5%,
p<0.01) and to be hospitalized (7% versus 3%, p<0.01). Acute myocardial
infarction occurred among 26 (0.4%) patients, more commonly among high
risk compared to low risk patients (1.1% versus 0.2%, p<0.01). Among high
risk patients, there was no difference between the intervention and
control groups in rates of performing electrocardiograms (51% versus 48%,
p=0.33) or administering aspirin (20% versus 18%, p=0.43). Among low risk
patients, there was no difference between intervention and control groups
in rates of cardiac stress testing (10% versus 9%, p=0.40). CONCLUSIONS:
Primary care management of chest pain is suboptimal for both high and low
risk patients. Electronic alerts do not increase risk-appropriate care for
these patients. Society of General Internal Medicine 2011.

Abstract
Background. Individual randomized trials have suggested that
everolimus-eluting stents may have improved clinical outcomes compared to
paclitaxel-eluting stents, but individual trials are underpowered to
examine outcomes such as mortality and very late stent thrombosis.
Methods. Medline, Cochrane, and conference proceedings were searched for
randomized trials comparing everolimus versus paclitaxel-eluting stents
for percutaneous coronary intervention. Results. 6792 patients were
included from 4 randomized controlled trials. Stent thrombosis was reduced
with everolimus stents versus paclitaxel stents (0.7% versus 2.3%; OR:
0.32; CI: 0.20-0.51; P<0.00001). The reductions in stent thrombosis were
observed in (i) early stent thrombosis (within 30 days) (0.2% versus 0.9%;
OR: 0.24; P=0.0005), (ii) late (day 31-365) (0.2% versus 0.6%; OR: 0.32;
P=0.01), and (iii) very late stent thrombosis (365 days) (0.2% versus
0.8%; OR: 0.34; P=0.009). The rates of cardiovascular mortality were 1.2%
in everolimus group and 1.6% in paclitaxel group (OR: 0.85; P=0.43).
Patients receiving everolimus-eluting stents had significantly lower
myocardial infarction events and target vessel revascularization as
compared to paclitaxel-eluting stents. Interpretation. Everolimus compared
to paclitaxel-eluting stents reduced the incidence of early, late, and
very late stent thrombosis as well as target vessel revascularization.

Abstract
We performed a randomised trial comparing the CEL-100 videolaryngoscope
with the Macintosh laryngoscope blade in 170 patients undergoing
double-lumen tube placement for thoracic surgery. Compared with the
Macintosh laryngoscope blade, use of the CEL-100 resulted in significantly
more patients with a Cormack and Lehane Grade-1 laryngeal view (90.4% vs
61.0%, p < 0.001), a higher rate of successful intubation on the first
attempt (92.8% vs 79.3%, p = 0.012), a lower median (IQR [range])
intubation difficulty score (0 (0-0 [0-60]) vs 15 (0-30 [0-80]), p <
0.001), a higher incidence of correct positioning of the tube (90.3% vs
79.2%, p = 0.041) and significantly fewer patients requiring external
laryngeal pressure (19.3% vs 32.9%, p = 0.046). Median (IQR [range]) time
to successful intubation was 45 (38-55 [22-132]) s with the CEL-100
compared with 51 (40-61 [30-160] s using the Macintosh laryngoscope blade.
We conclude that the CEL-100 videolaryngoscope is superior to the
Macintosh laryngoscope blade for double-lumen tube insertion. 2012 The

Abstract
Objectives: This study sought to perform a weighted meta-analysis to
determine the rates of major outcomes after transcatheter aortic valve
replacement (TAVR) using Valve Academic Research Consortium (VARC)
definitions and to evaluate their current use in the literature.
Background: Recently, the published VARC definitions have helped to add
uniformity to reporting outcomes after TAVR. Methods: A comprehensive
search of multiple electronic databases from January 1, 2011, through
October 12, 2011, was conducted using predefined criteria. We included
studies reporting at least 1 outcome using VARC definitions. Results: A
total of 16 studies including 3,519 patients met inclusion criteria and
were included in the analysis. The pooled estimate rates of outcomes were
determined according to VARC's definitions: device success, 92.1% (95%
confidence interval [CI]: 88.7% to 95.5%); all-cause 30-day mortality,
7.8% (95% CI: 5.5% to 11.1%); myocardial infarction, 1.1% (95% CI: 0.2% to
2.0%); acute kidney injury stage II/III, 7.5% (95% CI: 5.1% to 11.4%);
life-threatening bleeding, 15.6% (95% CI: 11.7% to 20.7%); major vascular
complications, 11.9% (95% CI: 8.6% to 16.4%); major stroke, 3.2% (95% CI:
2.1% to 4.8%); and new permanent pacemaker implantation, 13.9% (95% CI:
10.6% to 18.9%). Medtronic CoreValve prosthesis use was associated with a
significant higher rate of new permanent pacemaker implantation compared
with the Edwards prosthesis (28.9% [95% CI: 23.0% to 36.0%] vs. 4.9% [95%
CI: 3.9% to 6.2%], p < 0.0001). The 30-day safety composite endpoint rate
was 32.7% (95% CI: 27.5% to 38.8%) and the 1-year total mortality rate was
22.1% (95% CI: 17.9% to 26.9%). Conclusions: VARC definitions have already
been used by the TAVR clinical research community, establishing a new
standard for reporting clinical outcomes. Future revisions of the VARC
definitions are needed based on evolving TAVR clinical experiences. 2012

Abstract
Routine angiographic follow-up after bare-metal stent implantation has
been associated with an increase in coronary revascularization. The impact
of angiographic follow-up after drug-eluting stent placement remains
poorly characterized. The prospective, randomized, single-blinded SPIRIT
III trial assigned patients to the everolimus-eluting stent or the
paclitaxel-eluting stent (PES). Major adverse cardiovascular events
(cardiac death, myocardial infarction, and ischemia-driven target lesion
revascularization [ID-TLR]) at 3 years were assessed by angiographic
versus clinical-only follow-up at 8 months +/- 28 days and a landmark
survival analysis from 9 months to 3 years. Of 1,002 patients, 564
patients were assigned to angiographic follow-up at 8 months +/- 28 days
and 438 patients underwent clinical follow-up alone. Three-year major
adverse cardiovascular event rates were 10.6% in the angiographic group
and 12.0% in the clinical follow-up group (p = 0.64). Ischemia-driven
revascularization increased twofold at 9 months, but no difference was
noted in ID-TLR for either device. Non-ID-TLR was significantly higher in
patients in the angiographic group (4.5% vs 1.0%, p = 0.002), a difference
resulting from PES (9.1% vs 0.7%, p = 0.0007) rather than
everolimus-eluting stent (2.2% vs 1.1%, p = 0.36) treatment. The landmark
analysis showed no significant differences between the angiographic and
clinical follow-up groups from 9 months to 3 years of major clinical
outcomes. In conclusion, routine angiographic follow-up in SPIRIT III did
not increase rates of ID-TLR compared to clinical follow-up alone. Despite
higher nonischemia-driven revascularization rates with angiographic
follow-up of patients with PESs, none of the safety end points were
adversely affected. 2012 Elsevier Inc. All rights reserved.

Abstract
Background: Few trials have examined the outcomes of patients who use
cocaine with chest pain and who have a normal or nondiagnostic
electrocardiogram (ECG) and the use of single-photon emission computed
tomography (SPECT) myocardial perfusion imaging (MPI). Hypothesis: We
sought to compare the characteristics and overall outcomes in cocaine
users vs non-cocaine users presenting to the emergency department with a
normal/nondiagnostic ECG and to assess the value of rest MPI in both of
these populations. Methods: Patients with symptoms compatible with
myocardial ischemia, suspected acute coronary syndrome (ACS), and a
normal/nondiagnostic ECG were enrolled in the Emergency Room Assessment of
Sestamibi for Evaluation of Chest Pain (ERASE Chest Pain) trial, a
randomized controlled trial designed to evaluate the impact of rest MPI on
triage decisions. Cocaine users (n = 294) were compared to non-cocaine
users (n = 2180). Cocaine users were younger than non-cocaine users, and
72% were male. Results: Among the cocaine users, 2.4% had a myocardial
infarction, 1.4% required percutaneous coronary intervention, and none of
the patients underwent coronary artery bypass graft surgery. Among cocaine
users with a final diagnosis of not ACS, randomization of patients to rest
SPECT MPI resulted in an appropriate reduction in hospital admissions in
both the cocaine users (P = 0.011) and the non-cocaine users (P < 0.001),
suggesting improved triage when MPI was used. Conclusions: Cocaine users
with a normal/nondiagnostic ECG are at low risk of cardiac events. Even
though cocaine users are at low risk of cardiac events, SPECT MPI remains
effective in the risk stratification and improves triage management
decisions resulting in lower admission rates and more discharges to home.

Abstract
BACKGROUND: Blood for transfusion is stored for up to 42 days. Older blood
develops lesions and accumulates potentially injurious substances. Some
studies report increasing toxicity as blood ages. We assessed the safety
of transfused older versus newer stored blood. STUDY DESIGN AND METHODS:
PubMed, Scopus, and Embase were searched using terms new and old and red
blood cell and storage through May 6, 2011, for observational and
randomized controlled studies comparing outcomes using transfused blood
having longer and shorter storage times. Death was the outcome of
interest. RESULTS: Twenty-one studies were identified, predominantly in
cardiac surgery (n = 6) and trauma (n = 6) patients, including 409,966
patients. A test for heterogeneity of these studies' results was not
significant for mortality (I<sup>2</sup> = 3.7%, p = 0.41). Older blood
was associated with a significantly increased risk of death (odds ratio,
1.16; 95% confidence interval [CI], 1.07-1.24). Using available mortality
data, 97 (95% CI, 63-199) patients need to be treated with only new blood
to save one life. Subgroup analysis of these trials indicated that the
increased risk was not restricted to a particular type of patient, size of
trial, or amount of blood transfused. CONCLUSION: Based on available data,
use of older stored blood is associated with a significantly increased
risk of death.

Abstract
Background: Patients with severe aortic stenosis and coexisting
non-cardiac conditions may be at high risk for surgical replacement of the
aortic valve or even be no candidates for surgery. In these patients,
transcatheter aortic valve implantation (TAVI) is suggested as an
alternative. Results of the PARTNER (Placement of AoRTic TraNscathetER
Valve) trial comparing the clinical effectiveness of TAVI with surgical
valve replacement and standard therapy were published. The authors
assessed the cost-effectiveness of TAVI in Belgium. Methods: A Markov
model of incremental costs, effects (survival and quality of life) and
incremental cost-effectiveness of TAVI was developed. The impact on
survival, number of events and quality of life was based on the PARTNER
trial. Costs per event were context specific. Results: In high-risk
operable patients, even if the minor differences in 30-day and 1-year
mortality are taken into account, the incremental cost-effectiveness ratio
(ICER) remains on average above 750 000 per quality-adjusted life-year
(QALY) gained (incremental cost: 20 400; incremental effect: 0.03 QALYs).
In inoperable patients, an ICER of 44 900 per QALY (incremental cost: 33
200; incremental effect: 0.74 QALYs) is calculated, including a life-long
extrapolation of the mortality benefit. This result was sensitive to the
assumed time horizon. The subgroup of anatomically inoperable patients had
better outcomes than medically inoperable patients, with ICERs decreasing
more than 10 000/QALY. Conclusions: It is inappropriate to consider
reimbursement of TAVI for high-risk operable patients. Reimbursing TAVI in
inoperable patients in essence is a political decision. From an economic
perspective, it would be prudent to first target patients that are
inoperable because of anatomical prohibitive conditions. In the search for
evidence, the authors identified non-published negative results from a
randomised controlled TAVI trial. The study sponsor should be more willing
to share this information to allow balanced evaluations and policy
recommendations. Payers should require these data before taking
reimbursement decisions.

Abstract
Objective: To investigate the feasibility and safety of early dressing
removal of clean wounds following thoracotomy. Subjects and Methods: A
total of 230 patients (127 males, mean age 55.6 +/- 16.7 years) were
randomly divided into study and control groups. In the study group the
cotton gauze dressing was removed 48 h after the surgery, whereas in the
control group the dressing was kept on for 7-8 days until the removal of
skin sutures. The infection and healing of the wounds were examined, and
patients were followed up for 30 days. Results: There was no statistically
significant difference in age, sex, smoking rates, concurrent illnesses
and operational characteristics between the study and control groups (p >
0.05). The wound infection rate in the study and control groups was 6
(5.2%) and 7 patients (6.1%), respectively (p = 0.775). Two patients
(1.7%) from the study group and 1 (0.9%, p = 0.561) from the control group
had partial wound approximation by day 7. Surrounding skin integrity was
normal in 106 (92.2%) of the study group and 107 (93.0%) of the control
group patients by postoperative day 7 (p = 0.801). Conclusion: Removal of
wound dressing 48 h after thoracic surgery was not associated with an
increased risk of surgical site infection. Hence the early removal of
wound dressing did not appear to have an adverse impact on wound healing.

Abstract
Objectives: To explore the prognostic value of baseline estimated
glomerular filtration rate (eGFR) in Saudi patients presenting with ST
elevation myocardial infarction (STEMI), and its impact on hospital
therapies. Methods: The STEMI patients with a baseline serum Creatinine
enrolled in the SPACE (Saudi Project for Assessment of Coronary Events)
registry were analyzed. This study was performed in several regions in
Saudi Arabia between December 2005 to December 2007. Based on eGFR levels,
patients were classified into: more than 90.1 ml/min (normal renal
function), 90-60.1 (borderline/mildly impaired renal function), 60-30
(moderate renal dysfunction), and less than 30 ml/ min/1.73 m<sup>2</sup>
(severe renal dysfunction). Results: Two thousand and fifty eight patients
qualified for this study. Of these, 1058 patients had renal dysfunction.
Patients with renal dysfunction were older, and had a higher prevalence of
risk factors for atherosclerosis. Patients with moderate or severe renal
dysfunction were less likely to be treated with beta blockers, angiotensin
converting enzymes inhibitors, statins, or reperfusion therapies.
Significantly worse outcomes were seen with lower eGFR in a stepwise
fashion. The adjusted odds ratio of in-hospital death in patients with
eGFR less than 30ml/min was 5.3 (95% CI, 1.15-25.51, p=0.0383).
Conclusion: A low baseline eGFR in STEMI patients is an independent
predictor of all major adverse cardiovascular outcomes, and a marker for
less aggressive in-hospital therapy.

Abstract
Objectives: Outcomes following prosthetic patch infection after carotid
endarterectomy (CEA). Methods: Retrospective audit and systematic review.
Results: 22 patients were treated between January 1992 and April 2012, 5
having undergone their original CEA at another institution. The commonest
infecting organism was Staphylococcus. One patient was treated by
antibiotic irrigation, one was stented, while 20 underwent debridement and
patch excision plus; carotid ligation (n = 3), vein patching (n = 3) or
vein bypass (n = 14). There was one peri-operative stroke, but no
peri-operative deaths. There were no reinfections at a median follow-up of
54 months. A systematic review identified 123 patients with prosthetic
patch infection in the world literature. Thirty-six (29%) presented <2
months, 78 (63%) presented >6 months after the original CEA. Seventy-nine
of/87 patients (91%) with a positive culture yielded Staphylococci or
Streptococci. Seventy-four patients were treated by patch excision and
autologous reconstruction. Four (5%) developed reinfection <30 days, but
later reinfections have been reported. Seven of nine patients (78%)
undergoing prosthetic reconstruction either died or suffered reinfection.
Five patients were treated with a covered stent, none developing
reinfection (median followup 12 months). Conclusion: Patch infection
following CEA is rare. Few have undergone stenting and long term data are
awaited. For now, patch excision and autologous reconstruction remains the
'gold standard'. 2012 European Society for Vascular Surgery. Published by

Title
N-Acetylcysteine supplementation for the prevention of atrial fibrillation
after cardiac surgery: a meta-analysis of eight randomized controlled
trials.
Source
BMC cardiovascular disorders. 12 (pp 10), 2012. Date of Publication:
2012.
Abstract
Atrial fibrillation is the most common type of arrhythmia after cardiac
surgery. An increasing body of evidence demonstrates that oxidative stress
plays a pivotal role in the pathophysiology of atrial fibrillation.
N-acetylcysteine (NAC) is a free radical scavenger, and may attenuate this
pathophysiologic response and reduce the incidence of postoperative AF
(POAF). However, it is unclear whether NAC could effectively prevent POAF.
Therefore, this meta-analysis aims to assess the efficacy of NAC
supplementation on the prevention of POAF. Medline and Embase were
systematically reviewed for studies published up to November 2011, in
which NAC was compared with controls for adult patients undergoing cardiac
surgery. Outcome measures comprised the incidence of POAF and hospital
length of stay (LOS). The meta-analysis was performed with the
fixed-effect model or random-effect model according to the heterogeneity.
Eight randomized trials incorporating 578 patients provided the best
evidence and were included in this meta-analysis. NAC supplementation
significantly reduced the incidence of POAF (OR 0.62, 95% CI 0.41 to 0.93;
P = 0.021) compared with controls, but had no effect on LOS (WMD -0.07,
95% CI -0.42 to 0.28; P = 0.703). The prophylactic NAC supplementation may
effectively reduce the incidence of POAF. However, the overall quality of
current studies is poor and further research should focus on adequately
powered randomized controlled trials with POAF incidence as a primary
outcome measure. 2012 Gu et al; licensee BioMed Central Ltd

Abstract
Background/Purpose: RA patients are at a 2-fold risk of coronary artery
disease (CAD) compared with the general population. Immune dysregulation
is thought to contribute to this elevated risk of CAD, but the precise
mechanisms are unknown. We hypothesized that the burden of autoimmunity,
represented by the presence of autoantibodies, or autoimmune risk alleles
are associated with increased risk of CAD in RA. We tested this hypothesis
in RA and 2 diseases with pathognomonic autoantibodies and published
genetic risk alleles, systemic lupus erythematosus (SLE) and celiac sprue.
Both SLE and celiac also share genetic risk alleles with RA. Methods: This
study was conducted in a cohort of 1335 RA subjects identified from the
electronic medical records of a large academic institution using our
published algorithm. We identified RA subjects with prevalent CAD through
medical record review. Subjects were identified with CAD if they had a CAD
diagnosis by their treating physician and documentation of CAD after
cardiac catheterization, stress test, EKG or if they underwent
angioplasty, stent placement, or a coronary artery bypass graft. We
measured anti-nuclear antibodies (ANA), antibodies to tissue
transglutaminase (tTG), and antibodies to cyclic citrullinated peptide
(CCP) in all RA cases using commercial ELISA kits. We genotyped subjects
for 34 SLE, 17 celiac, 29 RA validated risk alleles based on GWAS and
meta-analyses, and 182 ancestry informative markers (AIMs). We conducted
our analysis in European American (EU) subjects to minimize population
stratification. We calculated a SLE, celiac, and RA count genetic risk
score (GRS) by adding the number of disease specific risk alleles for each
individual. We tested the association between ANA, tTG, CCP titers and CAD
outcome using logistic regression in 3 separate models. The association
between CAD outcome and disease-specific GRS was conducted using a
student's t-test separately for SLE, celiac and RA. Results: Among 1335 RA
cases, 81% were female, 70% were CCP positive, 76% had bone erosions, and
8% (n=111) had CAD; 84% (n=1124) were EU by AIMs of which 9% (n=100) had
CAD. In EU RA cases we observed an association between the celiac GRS and
CAD outcome (p=0.03). There was a suggestive trend of higher tTG titers
associated with increased risk of CAD (p=0.06). No association was
observed between the SLE and RA GRS and CAD outcome. Similarly we found no
association between ANA and CCP titers and CAD outcome in RA cases.
Conclusion: The unexplained risk for CAD in RA patients may be partially
explained by the burden of autoimmunity, in particular genetic
predisposition for celiac disease.

Abstract
Introduction-objective: Non-pharmacological interventions are important
alternatives for pain relief during minor procedures in neonates. The
purpose of this study was to compare the efficacy of different
non-pharmacological procedures in reducing pain response during blood
sampling through heel lance. Methods: In this randomised controlled trial,
136 healthy term newborn infants at Tertiary Public Hospital (Madrid) were
randomly assigned to four groups: (i) being breastfed with skinto- skin
contact (group 1, n = 35), (ii) receiving 2 mL oral 24% sucrose with
skin-to-skin contact with the mother (group 2, n = 35), (iii) being held
in skin-to-skin contact with the mother (group 3, n = 33) or (iv)
receiving 2 mL oral 24% sucrose (group 4, n = 33). Randomisation was by
closed envelopes and nurses and parents were masked to the randomization
group. All neonates were videotaped during the painful procedure (heel
lance). Heel lance was made with an automated piercing device for routine
neonatal screening for congenital disorders at 48 h of life. Patients were
excluded if previous capillar or venous sampling were made. Breastfeeding
was initiated at least 5 min before the procedure. Sucrose was given 2 min
before the procedure. Skin to skin contact was initiated at least 5 min
before the sample. Two observers watched the videos and measured pain by
Neonatal Infant Pain Scale. Duration of crying, % of crying while making
the procedure, heart rate and duration of sampling were also measured. A
inform consent was given to parents before including in the study. Data
were analysed per intention to treat. This study was approved by Local
Ethical Committee. Results: Coincidence between observers was 90.8% (95%
CI 87.8-93.8). There were no differences between groups in gestational
age, birthweight, Apgar score and gender. Mean NIPS score was 1.6 +/- 1.6
(group 1), 2.9 +/- 1.7 (group 2); 3.8 +/- 2 (group 3); and 3.5 +/- 1.8
(group 4) (p < 0.01 between group 1 and other groups). Length of crying
was significantly reduced in groups 1 and 2 versus groups 3 and 4 (p =
0.01). Percent of crying was lower in group 1 (p = 0.01). There were no
differences in heart rate not in the duration of sampling between groups.
(See Table 1). Conclusion: This study suggests that breastfeeding
associated with skin-to-skin contact provides superior analgesia for heel
lance in healthy term newborns compared with other kinds of
nonpharmacological analgesia. (Table presented) .

Abstract
Background: The clinical benefits of dual antiplatelet treatment (aspirin
+ clopidogrel) in the management of acute coronary syndromes (ACS) are
well established. However, clopidogrel is a prodrug that requires hepatic
activation. Concerns regarding its delayed onset of action, variability in
antiplatelet effects, and prolonged recovery of platelet function after
discontinuation have prompted the development of P2Y<sub>12</sub> receptor
antagonists. Ticagrelor is the most recently developed P2Y<sub>12</sub>
receptor antagonist available in the United States. Ticagrelor is a
nonthienopyridine antiplatelet agent and is the first reversible oral
antagonist of the P2Y<sub>12</sub> receptors. Objective: This article
reviews the pharmacology, clinical efficacy, and tolerability of
ticagrelor use in management of ACS. Methods: Peer-reviewed clinical
trials, review articles, and relevant treatment guidelines published from
1966 to March 15, 2012, were identified from the MEDLINE and Current
Content databases using the search terms ticagrelor, ACS,
pharmacokinetics, pharmacodynamics, pharmacoeconomics, and
cost-effectiveness. Citations from available articles were also reviewed
for additional references. Results: Nine pharmacokinetics/pharmacodynamics
studies in humans and 1 clinical study were identified. In addition, the
findings from 6 subanalyses based on the clinical study were included.
Compared with clopidogrel, ticagrelor was associated with a significantly
reduced composite rate of death from cardiovascular causes, myocardial
infarction, or stroke (ticagrelor, 9.8%; clopidogrel, 11.7%; hazard ratio
[HR] = 0.84; 95% CI, 0.77-0.92; P < 0.001). The difference in the rates of
major bleeding was not significant (ticagrelor, 11.6%; clopidogrel,
11.2%). Ticagrelor was associated with a higher rate of non-coronary
artery bypass graft surgery related major bleeding (4.5% vs 3.8%; P =
0.03), including fatal intracranial bleeding (0.1% vs 0.01%; P = 0.02),
and fewer cases of other types of fatal bleeding (0.1% vs 0.3%; P = 0.03).
Other adverse events reported with ticagrelor use included dyspnea
(13.8%), headache (6.5%), and bradyarrhythmia (5.8%). The effects of
ticagrelor have not been compared to those of other antiplatelet agents,
including prasugrel. Conclusions: Based on the findings from the present
review, ticagrelor provides reversible inhibition of adenosine
diphosphate-induced platelet aggregation, with a faster onset of action
than clopidogrel, and is effective in the treatment of patients with ACS.
More data are required to definitively position ticagrelor with respect to
other antiplatelet agents, including prasugrel. 2012 Elsevier HS

Abstract
Background: Intracoronary (IC) abciximab administration remains a
promising approach aimed to increase a drug concentration in the target
area and possibly improve clinical outcomes in the setting of ST-segment
elevation myocardial infarction (STEMI). The goal of this literature
review and meta-analysis is to update available knowledge comparing IC and
intravenous (IV) abciximab administration in STEMI patients. Methods: A
total of 7 randomized clinical trials (RCTs) with a median follow-up of 3
months were included in the meta-analysis (n = 3311). All-cause mortality
was selected as the primary end point while recurrent myocardial
infarction (re-MI), target vessel revascularization (TVR) and major
bleeding complications were the secondary end points. Results: IC
abciximab did not provide any benefits in terms of all-cause mortality as
compared with IV abciximab (odds ratio [OR] 0.67; 95% confidence interval
[CI] 0.34-1.34). However, this neutral effect was driven by the AIDA STEMI
trial. The IC route was associated with a reduced rate of re-MI when
compared with IV administration (OR 0.61; 95% CI 0.40-0.92) but the
difference disappeared after one of the RCTs was excluded from the
analysis. Both strategies were equal regarding TVR (OR 0.66; 95% CI
0.40-1.09) and major bleeding complications (OR 1.18; 95% CI 0.76-1.83).
Conclusions: Our updated meta-analysis shows that the clinical superiority
of IC over IV abciximab administration in STEMI patients is no longer
clear after the release of the AIDA STEMI trial results. Further research
in high-risk STEMI patients is warranted to finally determine clinical
advantages of IC vs IV abciximab administration. 2012 Via Medica.

Abstract
Rheumatic fever and rheumatic heart disease (RHD) are still important
problems in developing countries. Secondary prophylaxis which is the most
cost-effective method in preventing recurrences of rheumatic fever is
fraught with problems of drug compliance. The utility of 500 mg once
weekly azithromycin (AZT), an orally effective long-acting antibiotic was
evaluated against oral penicillin (phenoxy methyl penicillin 250 mg twice
daily) in this study. Forty-eight consecutive patients (44% males, mean
age 29.4 years) with established RHD were randomised into two groups-26
patients received AZT and 22 received oral penicillin. Patients were
evaluated at randomisation, at 1 month, 3 months, and 6 months,
clinically, serologically and by throat swab culture. End points were
absence of streptococcal colonisation, infection or fever at the end of 6
months. During the study, 4 patients (15.4%) in the AZT group developed
sore throat and fever, had positive throat culture and positive serology
indicating streptococcal infection. None satisfied the criteria for
rheumatic fever reactivation. None in the oral penicillin group developed
streptococcal infection. In conclusion, weekly 500 mg of AZT is not
effective in the prevention of streptococcal throat infection compared to
oral penicillin therapy in adult patients with established RHD. 2012.

Abstract
Background-The Department of Veterans Affairs Randomized On/Off Bypass
(ROOBY) trial compared clinical and angiographic outcomes in off-pump
versus on-pump coronary artery bypass graft (CABG) surgery to ascertain
the relative efficacy of the 2 techniques. Methods and Results-From
February 2002 to May 2007, the ROOBY trial randomized 2203 patients to
off-pump versus on-pump CABG. Follow-up angiography was obtained in 685
off-pump (62%) and 685 on-pump (62%) patients. Angiograms were analyzed
(blinded to treatment) for FitzGibbon classification (A=widely patent,
B=flow limited, O=occluded) and effective revascularization. Effective
revascularization was defined as follows: All 3 major coronary territories
with significant disease were revascularized by a FitzGibbon A-quality
graft to the major diseased artery, and there were no new postanastomotic
lesions. Off-pump CABG resulted in lower FitzGibbon A patency rates than
on-pump CABG for arterial conduits (85.8% versus 91.4%; P=0.003) and
saphenous vein grafts (72.7% versus 80.4%; P<0.001). Fewer off-pump
patients were effectively revascularized (50.1% versus 63.9% on-pump;
P<0.001). Within each major coronary territory, effective
revascularization was worse off pump than on pump (all P<=0.001). The
1-year adverse cardiac event rate was 16.4% in patients with ineffective
revascularization versus 5.9% in patients with effective revascularization
(P<0.001). Conclusions-Off-pump CABG resulted in significantly lower
FitzGibbon A patency for arterial and saphenous vein graft conduits and
less effective revascularization than on-pump CABG. At 1 year, patients
with less effective revascularization had higher adverse event rates.

Abstract
Background: Myocardial infarct size is a strong independent predictor of
mortality in patients with ST-elevation myocardial infarction (STEMI). In
the Harmonizing Outcomes with RevasculariZatiON and Stents in Acute
Myocardial Infarction (HORIZONS-AMI) trial, bivalirudin compared with
unfractionated heparin plus a glycoprotein IIb/IIIa inhibitor reduced
cardiac mortality in STEMI patients, which was attributed to reduced major
bleeding. Whether a possible reduction in infarct size with bivalirudin
may have contributed to the enhanced survival with this agent is unknown.
Methods: Cardiac magnetic resonance imaging was performed within 7 days
and after 6 months in 51 randomized patients from a single center in
HORIZONS-AMI trial (N = 28 bivalirudin, N = 23 heparin plus abciximab).
Infarct size, microvascular obstruction (MVO), left ventricular ejection
fraction (LVEF), and LV end-diastolic and end-systolic volume indices were
evaluated. Results: Infarct size was not significantly different after
treatment with bivalirudin compared with heparin plus abciximab either
within 7 days (median 9.3% [interquartile range 4.9%, 26.6%] vs. 20.0%
[5.9%, 28.2%], P = 0.28) or at 6 months 6.7% [3.8%, 20.0%] vs. 8.2% [1.8%,
16.5%], P = 0.73). MVO was present in 28.6% versus 34.8% of patients
respectively (P = 0.63). LVEF and LV volume indices also did not
significantly differ between the two groups at either time period, nor
were differences in myocardial recovery evident. Conclusions: In

Abstract
The aim of this single-blind, randomized, crossover trial was to test the
effect of Touch & Talk (T&T) for infants and toddlers less than 36 months
of age (N = 65) in the pediatric intensive care unit on their
physiological stability and recovery to an invasive procedure. In the T&T
condition, mothers touched, sang, or told stories or rhymes to their child
during an invasive procedure. In the control condition, the mothers did
not have contact with their child. Physiological measures included heart
rate, heart rate variability, and oxygen saturation range during the
procedure and change from baseline. Time from the end of the procedure
until the heart rate returned to baseline levels gave the recovery time.
Analysis was conducted using repeated-measures analysis of covariance.
There were no significant differences on any of the physiological
parameters by condition during the procedure. However, when controlling
for severity of illness, recovery was faster with mothers. 2012 Elsevier

Abstract
Background: Glycemic control is important to patients' outcomes. However,
the process of maintaining glycemic control is risk laden and labor
intensive for nurses. Objectives: To examine the effects of using a
computerized insulin dose calculator to facilitate management of glycemic
control for critically ill cardiac patients. Methods: A prospective
randomized controlled trial was conducted with a sample of 300 intensive
care patients, 141 randomized to the calculator group and 159 in the
control (paper protocol) group. A convenience sample of 44 intensive care
nurses responded to a nurse satisfaction survey. Results: A significantly
higher percentage of glucose measurements were in the target range in the
calculator group than in the control group (70.4% [SD, 15.2%] vs 61.6%
[SD, 17.9%], Z = -4.423, P <.001), and glucose variance was significantly
less in the calculator group (35.5 [SD, 18.3] mg/dL vs 42.3 [SD, 21.2]
mg/dL, Z = -3.845, P <.001). Fewer hypoglycemic events occurred in the
calculator group (7 vs 18), although this difference was not statistically
significant. Nurse satisfaction was higher for the calculator group than
for the control group (8.4 [SD, 1.4] vs 4.8 [SD, 2.4], Z = -5.055, P
<.001). Nurses' deviation from the protocol was also less in the
calculator group than in the control group. Conclusions: Management of
glycemic control and nurse satisfaction were improved with use of the dose
calculator. Improving nurses' processes of care may improve nurses' use of
time and patient care overall. Studies with larger sample sizes over time
are needed to determine these relationships. 2012 American Association of

Abstract
OBJECTIVES: N-3 polyunsaturated fatty acids have been proposed as a novel
treatment for preventing postoperative atrial fibrillation due to their
potential anti-inflammatory and anti-arrhythmic effects. However,
randomized studies have yielded conflicting results. The objective of this
study is to review randomized trials of N-3 polyunsaturated fatty acid use
for postoperative atrial fibrillation. METHODS: Using the CENTRAL, PUBMED,
EMBASE, and LILACS databases, a literature search was conducted to
identify all of the studies in human subjects that reported the effects of
N-3 polyunsaturated fatty acids on the prevention of postoperative atrial
fibrillation in cardiac surgery patients. The final search was performed
on January 30, 2011. There was no language restriction, and the search
strategy only involved terms for N-3 polyunsaturated fatty acids (or fish
oil), atrial fibrillation, and cardiac surgery. To be included, the
studies had to be randomized (open or blinded), and the enrolled patients
had to be $18 years of age. RESULTS: Four randomized studies (three
double-blind, one open-label) that enrolled 538 patients were identified.
The patients were predominantly male, the mean age was 62.3 years, and
most of the patients exhibited a normal left atrial size and ejection
fraction. N-3 polyunsaturated fatty acid use was not associated with a
reduction in postoperative atrial fibrillation. Similar results were
observed when the open-label study was excluded. CONCLUSIONS: There is
insufficient evidence to suggest that treatment with N-3 polyunsaturated
fatty acids reduces postoperative atrial fibrillation. Therefore, their
routine use in patients undergoing cardiac surgery is not recommended.

Abstract
Objective: To evaluate the efficacy and safety of dexmedetomidine for
emergence agitation after tonsillectomy in children. Methods: 120 ASA
physical status I and II children, aged 5-14 years, undergoing anesthesia
for tonsillectomy, were randomly divided into 3 groups: Placebo group, the
low dexmedetomidine concentration group and the high dexmedetomidine
concentration group. Before the entrance of the operating room (OR), all
of the children received intravenous injection 40mugkg<sup>-1</sup>
midazolam to reduce anxiety at first, and then dexmedetomidine was given
intravenously at an initial loading dose of 0.5mugkg<sup>-1</sup> or
1mug/kg over a 10-min period via a computer controlled infusion pump
followed by a maintenance infusion of 0.2mugkg<sup>-1</sup>h<sup>-1</sup>
or 0.4mugkg<sup>-1</sup>h<sup>-1</sup>over the surgery. The heart rate,
SpO<sub>2</sub> and mean arterial blood pressure were recorded for each
patient in both operation room and PACU. The designated time points: at
the start of the anesthetic induction, at the discontinuation of
inhalational agents, at first opening of eyes, at time to remove
endotracheal tube were recorded. After patient arrival at the PACU, VAS
score, RSS, the occurrence of emergence agitation were recorded every 5min
for the first 30min and every 10min for the next 30min after endotracheal
tube was removed. Results: There was significant difference in the
incidence of emergence agitation between Placebo group and the high
concentration group when endotracheal tube was removed (P<0.05). There was
significant difference in the VAS pain scores and in the RSS between three
groups at the time of extubation, as well as 5. min and 10. min after
extubation (P<0.05). Conclusions: Dexmedetomidine appears to be safe and
effective to reduce the incidence of early emergence agitation in children
after tonsillectomy. Initial loading dose of 1.0mugkg<sup>-1</sup>
followed by a maintenance infusion of 0.4mugkg<sup>-1</sup>h<sup>-1</sup>
is better choice for children received tonsillectomy. 2012 Elsevier

Abstract
BACKGROUND: A paucity of studies has examined the effect of exercise
training after left ventricular assist device (LVAD) implantation.
Previous research has demonstrated that insertion of the LVAD alone
improves exercise capacity and quality of life (QOL). This study
investigated whether supervised exercise training results in a further
improvement. METHODS: This prospective, randomized controlled trial with
concealed allocation, assessor blinding, and intention-to-treat analysis
investigated the effect of exercise training on exercise capacity and QOL
in 14 patients who underwent LVAD insertion as a bridge to heart
transplantation. Exercise training consisted of 8 weeks of gym-based
aerobic and strengthening exercises 3 times a week, with a progressive
mobilization program, compared with the control group that completed
mobilization alone. Exercise capacity was measured before and after the
intervention using maximal cardiopulmonary exercise testing and 6-minute
walk distance (6MWD). QOL was measured using the Short Form 36-item
assessment. RESULTS: No adverse events were reported. There was a trend
toward greater improvement in peak oxygen consumption (Vo<sub>2</sub>),
6MWD, and QOL in the exercise group (n = 7) compared with the control
group (n = 7); however, no significant between-group difference was
detected for improvements in peak Vo<sub>2</sub> [mean difference
(exercise - control)] of 2.96 ml/kg/min (95% confidence interval, -1.04 to
6.97), 6MWD at 54 meters (-51 to 159 meters), and QOL scores over time (p
> 0.05). CONCLUSION: Exercise training is feasible and safe in patients
with a LVAD. Trends toward greater improvement in exercise capacity and
QOL after exercise training warrant further investigation in a larger
trial. Crown Copyright 2012 Published by Elsevier Inc. on behalf of the

Abstract
Introduction: Neurocognitive deficits after cardiac surgery are described
in 4 to 33% of patients in the first 7 days. Postulated explanations are
microembolization of small brain arterioles with air or solid particles
and use of the extracorporeal circulation (ECC). Despite de-airing in
valve surgery, some air always remains captured in pulmonary veins and
evacuates only after weaning from ECC. Field flooding is a technique which
aims to replace air in the surgical wound cavity with carbon dioxide,
which should pose less danger of microemboli because of its greater
solubility. Conducted research studies have shown various results, but the
matter remains unresolved. S100B is a small astroglial protein and is
released to blood plasma after brain injury. Its increase after cardiac
surgery has been connected with neurocognitive dysfunction. Method: We
conducted a randomized controlled clinical trial on mitral valve
procedures in a study group of 49 patients and 51 in a control group.
Exclusion criteria were: minimal invasive operations, concomitant aortic
valve and aorta procedures or brain damage incidents in the past. All the
operations were performed by classic access and most of them were combined
cardiac procedures. Carbon dioxide insufflation at 6 litres per minute was
administered by a multiperforated drain with closed end in the study
group, starting 60 seconds before opening the left atrium. Blood samples
for S100B measurement were taken before the operation, 2 h after
cross-clamp release and 24 h postoperatively. Results: There were no
statistically valid differences between groups in S100B increase at 2 h
and 24 h postoperatively, despite a 13% higher short term marker increase
in the control group. Increase of S100B at 2 h was statistically greater
in patients after mitral valve replacement (MVR) compared to plasty (MVP)
group and correlated with concomitant tricuspid valve plasty (TVP),
although the TVP group had greater bypass times. Conclusion: Lack of
strong evidence makes routine use of CO2 slightly unjustified, but the
matter requires further studies. MVP patients may have better neurologic
outcome than MVR, but have different organic valve disease.

Abstract
Introduction: Off-pump coronary artery bypass is frequently used in
cardiac surgery and may be useful in some clinical situations. During
OPCAB, rotating and compressing the beating heart may result in acute
deterioration of haemodynamics and monitoring of CO in continuous mode
(CCO) is clinically useful. The FloTrac/Vigileo is a minimally invasive
system to monitor CCO without calibration. The aim of this study on OPCAB
patients was 1) to assess the accuracy of the new third generation
(version 3.02) FloTrac/Vigileo software; 2) to compare the new version
with the previous one (version 1.10). Method: Twenty patients submitted to
OPCAB were included in this study. The CO was measured simultaneously with
FloTrac/Vigileo (version 3.02) and by single-bolus thermodilution (in
triplicate) at 5 time points: T1, after anaesthesia induction; T2, left
anterior descending anastomosis; T3, obtuse marginal anastomosis; T4,
posterior descending anastomosis; T5, sternal closure. Bland Altman
analysis was used to compare Trac / Vigileo and Thermodilution
measurements. Percentage Error (PE), concordance rate, and correlation
coefficient were also evaluated. Results: Table 1 shows the main results
of the study. CCO FloTrac well correlated with ther- (Table presented)
modilution measurements although PE was little higher then 30 %.
Conclusions: The new version of software shows a good correlation with
thermodilution but accuracy and precision is little below the current
benchmark. The new algorithm provides improvement over the previous
version. In the light of the recent meta-analysis on minimal invasive CO
[1] and of data of this study, FloTrac Vigileo may be a valuable tool
during OPCAB.

Abstract
Introduction: The aim was to evaluate the effect of sevoflurane compared
to propofol on the incidence of postoperative nausea and vomiting (PONV),
headache, and vertigo after major non-cardiac surgery. Method: This is a
secondary analysis of a randomized, controlled, multi-centre trial of
sevoflurane vs. propofol to reduce myocardial ischaemia. PONV, headache
and vertigo were pre-specified, systematically collected tertiary
endpoints. PONV was defined as nausea or vomiting or postoperative use of
antiemetics. Patients were induced with etomidate and maintained with
sevoflurane or propofol as allocated. Side effects were assessed by visits
on postoperative days 1, 2 and 7 or discharge day whichever occurred
first. We tested for differences across treatment groups by chi-squared or
Fisher's exact test as appropriate. Results: We enrolled 385 patients.
Five patients dropped out (3 patients in the sevoflurane group), leaving
181 patients in the sevoflurane and 199 patients in the propofol groups.
Side-effect data were missing in 1% on days 1 and 2, and in 11% on day 7.
Sex (P=0.547), smoking (P=0.561), surgery duration (P=0.489), and choice
of opioids (fentanyl P=0.508, alfentanil P=0.950, sufentanil P=0.596,
remifentanil P=0.507, methadon P=0.573) did not differ between groups.
None of the patients underwent procedures typically associated with PONV
[1].The table (Table presented) reports the results (percentages refer to
patients with available data). Conclusion: Compared to propofol,
anaesthesia maintenance with sevoflurane was associated with increased
PONV on postoperative day 1 but without persistence thereafter. In
contrast, the type of anaesthesia did not affect the incidences of
headache or vertigo.

Abstract
Introduction: The aim was to evaluate the effect of sevoflurane compared
to propofol on patients' satisfaction after major non-cardiac surgery.
Method: This is a secondary analysis of a multicentre randomized
controlled trial of sevoflurane vs. propofol to reduce perioperative
ischaemia in patients at cardiovascular risk. Patients' satisfaction was a
prespecified tertiary endpoint and was collected systematically by visual
analogue scale in 2 study centres. The scale ranges from 0 to 10 with low
values indicating low satisfaction. Patients were induced by etomidate and
maintained by sevoflurane or propofol as randomized. Research staff
visited the patients on postoperative days 1, 2, and day 7 or discharge
day whichever occurred first, and assessed satisfaction. We tested for
differences in the VAS distribution across treatment groups by
Mann-Whitney U test. We tested for dichotomous variables by chi-squared or
Fisher's exact test, as appropriate. The big majority (97%) of the
patients was enrolled in one of the centres; therefore, we did not
stratify the satisfaction analysis by centre. Results: We analysed 284
patients, thereof 57.7% underwent major vascular surgery. Four patients
dropped out (2 patients in the sevoflurane group) leaving 137 patients in
the sevoflurane and 143 patients in the propofol groups. VAS data were
missing in 2% of the patients on day 1, 1% on day 2, and 15% on day 7.
Four percent (11/280), 5% (14/280) and 3% (9/280) of the patients were not
able to quantify their satisfaction by VAS on postoperative days 1, 2 and
7, respectively. These proportions did not differ across treatments. The
median VAS was 7 (interquartile range [IQR] 5-8) on days 1 and 2 in both
the sevoflurane and the propofol group. On day 7 the median VAS was 8 (IQR
6-9) in the sevoflurane and 7 (IQR 5-9) in the propofol group. The VAS
distribution did not differ across the two groups at any time-point (P=
0.173 on day 1, P=0.734 on day 2, P=0.122 on day 7). Conclusion: The
choice of sevoflurane or propofol did not affect the patients'
satisfaction after major noncardiac surgery.

Abstract
Introduction: Remote ischaemic conditioning (RIC) is an intriguing method
to induce resistance against ischaemia reperfusion injury and can be used
in a variety of clinical settings. Available studies mostly focus on
surrogate endpoints, such as biomarker release. We performed a systematic
review and metaanalysis to investigate whether RIC reduces mortality,
major adverse cardiovascular events, length of stay in hospital and in the
intensive care unit, as well as biomarker release, in patients who suffer
from or are at risk for ischaemia reperfusion injury. Method: Medline,
EMBASE and Cochrane databases were searched for abstracts of randomized
clinical trials comparing RIC, regardless of timing, with no conditioning.
Abstracts were screened by two investigators, who independently selected
suitable trials, assessed trial quality and extracted data. Results: In
total, 23 studies were included on patients undergoing cardiac surgery (15
studies), percutaneous coronary intervention (four studies) and vascular
surgery (four studies), compromising 1878 patients. Compared to no
conditioning, RIC did not reduce mortality (odds ratio 1.22 [95%
confidence interval 0.48, 3.07]) or major adverse cardiovascular events
(0.65 [0.38, 1.14]). However, the incidence of myocardial infarction was
reduced with RIC (0.50 [0.31, 0.82], P<0.005), as was peak troponin
release (mean difference -0.28 [-0.47, -0.09], P<0.01). A subgroup
analysis of the different study populations was not performed, due to
insufficient number of trials. Conclusion: We found no evidence that RIC
reduces mortality or the incidence of associated major adverse
cardiovascular events after ischaemic injury. However, the data did show a
reduction in the incidence of peri-procedural myocardial infarction, as
well as reduced release of troponin after RIC.

Abstract
Introduction: In the last two decades, coronary artery bypass grafting
(CABG) surgery has increasingly been performed without cardiopulmonary
bypass (CPB), that is 'offpump'. A strong motivation for performing CABG
surgery off-pump was to avoid CPB which has been believed to cause
cognitive decline. However, accumulating evidence from systematic reviews
and meta-analyses comparing on- and off-pump CABG surgery indicates that
CPB may not be the cause of cognitive decline [1]. Several additional
randomized controlled trials (RCTs) comparing cognition after on- and
off-pump CABG surgery have been published since the last metaanalyses. The
aim of this study was to undertake a systematic review of the literature
and meta-analysis to compare cognition following on- and off-pump CABG
surgery. Method: RCTs comparing continuous measures of cognitive outcome
after on- and offpump CABG surgery were identified by literature
searching. Data extraction enabled data from seven psychometric tests
(Auditory Verbal Learning Test, Grooved Pegboard, Trail-Making A and B,
Digit Symbol, Digit Span, and Stroop Colour Word Test) to be amalgamated.
Data was grouped into early (< six months) and late (>= six months)
postoperative periods and analysed using Revman 5. Results: A systematic
literature search conducted in Medline, Embase, PsychINFO and The Cochrane
Library yielded 13 studies totalling 2285 patients that could be included
in the meta-analysis. No significant differences were found between on-
and off-pump groups in any of the psychometric tests in either early or
late postoperative periods. Discussion: To-date, this is the largest
metaanalysis comparing cognition following onand off-pump CABG surgery and
the absence of difference is consistent with previous systematic reviews
and meta-analyses. The results are highly suggestive that CPB may not be
the cause of cognitive decline associated with CABG surgery.

Abstract
Background: Determination of the optimal hemoglobin concentration (Hb) for
red cell (RBCs) transfusion is essential for patients undergoing cardiac
surgery as mortality may be dependent on the severity of anemia and
administration of RBCs. As there is considerable variability in
transfusion practices, a pilot feasibility study is required to ensure
that adherence to proposed strategies can be achieved before conducting a
definitive study requiring thousands of patients. The primary objective of
this study was to assess overall adherence to two transfusion strategies.
Methods: We conducted a single centre parallel randomized controlled pilot
trial to assess adherence to two transfusion strategies. The randomization
sequence was created using block randomization by age and Cardiac
Anesthesia Risk Score in groups of 4. High risk patients were allocated to
a "restrictive" transfusion strategy (RBCs if their Hb was 70 g/L or less
intraoperatively during cardiopulmonary bypass (CPB) and 75 g/L or less
postoperatively following CPB); or a "liberal" transfusion strategy (RBCs
if their Hb was 95 g/L or less during CPB and less than 100 g/L
postoperatively). We defined adherence as adherence to the transfusion
strategies for each patient for more than 90% of their days in hospital.
We also assessed reasons for non-adherence and clinical outcomes. A total
sample size of 50 patients was estimated to produce a 97% confidence
interval equal to the sample adherence prevalence plus or minus 8% when
the true prevalence of adherence was hypothesized to be 90%. We estimated
our sample size using PASS 2002 software. The significance level was set
at p<0.05 for all statistical analyses. Results: Fifty patients were
randomized, 25 in the liberal group and 25 in the restrictive group.
Overall, 99 units of RBCs were transfused in the liberal group compared 50
units in the restrictive group (p<0.01). Forty eight units of RBCs were
administered intraoperatively for the liberal group compared to 14 RBC
units for the restrictive group (p< 0.01). Ninety eight units were
transfused in the liberal group according to the transfusion strategy
compared to 42 units in the restrictive group (p=0.01). The median number
of days of adherence to the transfusion strategy was 8 (interquartile
range 12) in the restrictive arm and 6 days (interquartile range 3) in the
liberal arm (Table, p<0.05). The proportion of patients with 100%
adherence was higher in the liberal group i.e., more patients in the
restrictive group received transfusions without meeting a transfusion
criterion. This was also reflected in the proportion of red cells
administered according to the transfusion strategy. The percent of adhered
transfusion thresholds was 70% in the restrictive arm and 65% in the
liberal arm. The adherence rate was highest in the operating room followed
by the cardiovascular intensive care unit then the ward (Table). Reasons
for non adherence included attending staff opinion that transfusion not
indicated, patient refusal, the use of hemoconcentration to increase the
hemoglobin concentration, hemorrhage, use of hematocrit instead Hb to
transfuse the patient, confusion whether the transfusion strategy was to
be applied on the ward, hyperkalemia, repetition of the complete blood
count before transfusing the patient, and the staff was too busy. (Table
Presented) Conclusions: This is the first randomized controlled trial that
has assessed adherence rates to transfusion strategies in high-risk
patients undergoing cardiac surgery. Determination of adherence rates to
transfusion strategies is essential as adherence rates can impact outcomes
if a considerable proportion of enrolled patients do not receive a
transfusion according to their transfusion strategy. Poor adherence may
impact outcomes despite the subsequent use of intention to treat analysis.
Restrictive strategies can reduce transfusion, but further studies will be
required to determine whether restrictive transfusions confer risk.

Abstract
Background: It remains unclear whether angiotensin-converting enzyme
inhibitors (ACEIs) or angiotensin II type 1 receptor blockers (ARBs) have
fully delivered the expected reduction in cardiovascular diseases. We
investigated the effects of adding the direct renin inhibitor (DRI),
aliskiren, to an ACEI or an ARB on monocyte subsets and myocardial salvage
in patients with primary acute myocardial infarction (AMI). Methods and
Results: Twenty-one consecutive patients were treated with an ACEI or an
ARB (non-DRI group), and another 21 consecutive patients received
aliskiren combined with an ACEI or an ARB (DRI group). Two monocyte
subsets (CD14<sup>+</sup>CD16<sup>-</sup>and
CD14<sup>+</sup>CD16<sup>+</sup>) were measured by flow cytometry. The
extent of myocardial salvage 7 days after AMI was evaluated by cardiac
magnetic resonance imaging. Both plasma renin activity and aldosterone
levels were significantly lower in the DRI group than in the non-DRI
group. Peak levels of CD14<sup>+</sup>CD16<sup>-</sup> monocyte number and
ratio were also significantly lower in the DRI group. The extent of
myocardial salvage was significantly higher in the DRI group than in the
non-DRI group (44.8 [41.2-53.1] vs. 36.0 [28.5-42.6], P=0.001).
Conclusions: A DRI combined with an ACEI or an ARB can better improve the
extent of myocardial salvage after AMI than an ACEI or an ARB alone in
association with the decrease in circulating
CD14<sup>+</sup>CD16<sup>-</sup> monocytes.

Abstract
Although coronary arterial fistula is rare, it is one of the most common
among the coronary artery anomalies. Coronary arterial fistula most
commonly affects the right side of the heart. It may occur isolated or
along with congenital heart diseases. Angiography remains the best
investigation for diagnosing the disease. Unless very large and
hemodynamically significant, it is usually asymptomatic in younger
patients. With increasing age, symptoms begin to appear, and the incidence
of complication rises. Treatment by transcatheter or surgical closure
gives the best results, provided this is performed early in the course of
the disease. This review was prepared by searching the terms "coronary
artery fistula," "coronary cameral fistula," "surgical management of
coronary arterial fistula," "MDCT in coronary artery fistula," and
"multiple coronary artery fistulae" in Google Scholar, PubMed, and PubMed
Central and exploring the related articles shown on the side of page.

Abstract
As pain in the intensive care unit (ICU) is still common despite important
progress in pain management, we studied the efficacy of an intravenous
bolus of morphine 2.5 vs 7.5 mg for procedural pain relief in patients
after cardiothoracic surgery in the ICU. In a prospective double-blind
randomised study, 117 ICU patients after cardiothoracic surgery were
included. All patients were treated according a pain titration protocol
for pain at rest, consisting of continuous morphine infusions and
paracetamol, applied during the entire ICU stay. On the first
postoperative day, patients were randomised to intravenous morphine 2.5
(n=59) or 7.5 mg (n=58) 30 minutes before a painful intervention (turning
of patient and/or chest drain removal). Pain scores using the numeric
rating scale (Numeric Rating Scale, range 0 to 10) were rated at rest
(baseline) and around the painful procedure. At rest (baseline), overall
incidence of unacceptable pain (Numeric Rating Scale >=4) was low (Numeric
Rating Scale >4; 14 vs 17%, P=0.81) for patients allocated to morphine 2.5
and 7.5 mg respectively. For procedure-related pain, there was no
difference in incidence of unacceptable pain (28 vs 22%, P=0.53) mean pain
scores (2.6 [95% confidence interval 2.0 to 3.2] vs 2.7 [95% confidence
interval 2.0 to 3.4]) between patients receiving morphine 2.5 and 7.5 mg
respectively. In intensive care patients after cardiothoracic surgery with
low pain levels for pain at rest, there was no difference in efficacy
between intravenous morphine 2.5 mg or morphine 7.5 mg for pain relief
during a painful intervention.

Off-pump versus on-pump coronary artery bypass grafting for ischaemic
heart disease.

Date of Publication: 2012.
Abstract
Coronary artery bypass grafting (CABG) is performed both without and with
cardiopulmonary bypass, referred to as off-pump and on-pump CABG
respectively. However, the preferable technique is unclear. To assess the
benefits and harms of off-pump versus on-pump CABG in patients with
ischaemic heart disease. We searched the Cochrane Central Register of
Controlled Trials (CENTRAL) on The Cochrane Library (Issue 1, 2011),
MEDLINE (OVID, 1950 to February 2011), EMBASE (OVID, 1980 to February
2011), Science Citation Index Expanded on ISI Web of Science (1970 to
February 2011) and CINAHL (EBSCOhost, 1981 to February 2011) on 2 February
2011. No language restrictions were applied. Randomised clinical trials of
off-pump versus on-pump CABG irrespective of language, publication status
and blinding were selected for inclusion. For statistical analysis of
dichotomous data risk ratio (RR) and for continuous data mean difference
(MD) with 95% confidence intervals (CI) were used. Trial sequential
analysis (TSA) was used for analysis to assess the risk of random error
due to sparse data and to multiple updating of accumulating data.
Eighty-six trials (10,716 participants) were included. Ten trials (4,950
participants) were considered to be low risk of bias. Pooled analysis of
all trials showed that off-pump CABG increased all-cause mortality
compared with on-pump CABG (189/5,180 (3.7%) versus 160/5144 (3.1%); RR
1.24, 95% CI 1.01 to 1.53; P =.04). In the trials at low risk of bias the
effect was more pronounced (154/2,485 (6.2%) versus 113/2,465 (4.6%), RR
1.35,95% CI 1.07 to 1.70; P =.01). TSA showed that the risk of random
error on the result was unlikely. Off-pump CABG resulted in fewer distal
anastomoses (MD -0.28; 95% CI -0.40 to -0.16, P <.00001). No significant
differences in myocardial infarction, stroke, renal insufficiency, or
coronary re-intervention were observed. Off-pump CABG reduced
post-operative atrial fibrillation compared with on-pump CABG, however, in
trials at low risk of bias, the estimated effect was not significantly
different. Our systematic review did not demonstrate any significant
benefit of off-pump compared with on-pump CABG regarding mortality,
stroke, or myocardial infarction. In contrast, we observed better
long-term survival in the group of patients undergoing on-pump CABG with
the use of cardiopulmonary bypass and cardioplegic arrest. Based on the
current evidence, on-pump CABG should continue to be the standard surgical
treatment. However, off-pump CABG may be acceptable when there are
contraindications for cannulation of the aorta and cardiopulmonary bypass.
Further randomised clinical trials should address the optimal treatment in
such patients.

Title
Modeling the effects of bivalirudin in cardiac surgical patients.

Abstract
Bivalirudin is direct thrombin inhibitor used in patients with
heparin-induced thrombocytopenia. A pharmacokinetic and--dynamic model
that predicts the partial thromboplastin time (PTT) based on the past
infusion rates of bivalirudin following dose adjustment would be useful to
guide optimal therapy. In this retrospective study we randomized 132
patients to a derivation and a validation cohort, and tested two models.
The first model is a single-state linear model; the other incorporates a
non-linear element to account for renal elimination of bivalirudin. Both
models predicted PTT changes equally well with root-mean squared errors of
15 to 16 seconds (Pearson correlation coefficients for both were 0.67).
Intra- and inter-individual variability of response to bivalirudin was
significant. Although a high percentage of patients had moderate to severe
renal dysfunction at one point during the bivalirudin infusion, the
non-linear model that incorporates variable renal clearance of drug did
not perform better than the linear model. This finding persisted even in
the subgroup analysis of patients with moderate and low estimated
glomerular filtration rates.

Abstract
The issue of immunomodulation by blood transfusions started with the
publication by Opelz and Terasaki on a multivariate analysis of
observational studies showing a significant enhancement of survival of
kidney grafts in recipients of multiple transfusions compared to
non-transfused patients1. This gave rise to concern for wider consequences
of this immunosuppressive transfusion effect for instance on
immunosurveillance against cancer, as was raised by Gantt2. Since then,
transfusion-related immunomodulation (TRIM) is claimed to cause
postoperative nosocomial infections, recurrence of (and new) malignancies
and leading to increased mortality after surgery. Transplantation
tolerance By showing that a single blood transfusion improved graft
survival, provided the blood was not leukocyte-depleted, Persijn and
colleagues made a causal role for allogeneic leukocytes in transplantation
tolerance very likely3. The beneficial effect of pretransplant blood
transfusions is not restricted to cadaver kidney transplantation. Over the
last 30 years a beneficial effect has been published in heart, liver, and
combined pancreas-kidney transplantation. Also, new and highly effective
immunosuppressive drugs to prevent or treat rejection were developed. It
is difficult to compare the effect of a pretransplant blood transfusion
between studies with a historical control group, since outcome after organ
transplantation depends on several factors which cannot be controlled for
in a retrospective study. Although a beneficial transfusion effect remains
present, notwithstanding the use of modern immunosuppressive drugs,
deliberate pre-transplant transfusions are currently virtually abandoned.
The main reasons are concerns about transfusiontransmitted diseases and
development of alloimmunization, where also the results without
transfusion have improved considerable. Immunological effects of blood
transfusions Transfusions affect both the innate and the adaptive immune
system. Transfusions contain many foreign antigens and always apoptotic
and necrotic cells (more with longer storage; less in filtered units). The
apoptotic cells interact with macrophages which start to produce
anti-inflammatory cytokines such as prostaglandin E-2 and TGF-s. Thereby
not only suppressing the innate immune response of macrophages and NK
cells but also impairing the antigen presenting cell (APC) capacity,
thereby down regulating the adaptive antigen-specific immune response.
Soluble response modifiers accumulate in blood products during storage.
Factors derived from leucocytes are e.g. elastase, soluble HLA class I and
II molecules, sFasL, IL-1, IL-6, and IL-8. Proinflammatory cytokines are
an important cause of nonhemolytic febrile transfusion reactions (NHFTR).
With the introduction of universal leukocyte reduction most countries
reported a decline in NHFTR. Due to phosphorylation defects, the responder
capacity of T cells decreases during storage, impairing the protein
synthesis of T cells upon signaling of the T cell receptor. This reduces
the proliferative response of donor lymphocytes, relevant to impaired
transfusion-associated Graft-versus-Host disease4. The stimulator capacity
by donor APCs of the direct pathway is irreversibly abrogated after 10-14
days of storage because of loss of co-stimulatory molecules, which are
essential for effective APC-helper T cell interaction5. This leaves only
the, less efficient, indirect pathway to elicit an adaptive immune
response after processing of foreign donor antigens. This indirect pathway
is dependent on APCs, which may be affected by pro- and/or
anti-inflammatory stimuli in the blood product. After transfusion, there
is a two-way interaction between donor and recipient cells. Three to five
days after transfusion, depending on the storage interval of contaminant
leukocytes, proliferating lymphocyte blasts can be found in the
circulation6. Most donor DNA disappears after a week, although
haplo-identical cells sharing an HLA-DR antigen can remain detectable for
several weeks. Persistence of donor cells for many years is observed in
approximately 20% of apparently healthy transfused trauma survivors, even
after transfusions of leukocyte-reduced blood stored for longer than 3
weeks. This transfusion-induced chimerism is not associated with apparent
clinical disease; a role for this chimerism in allogeneic
(transplantation) tolerance has not yet been investigated. Cancer
immunosurveillance A deleterious role of blood transfusions on cancer
surveillance was feared because of immunological analogy between
alloimmunity (e.g. organ graft rejection) and tumor immunity. This was
further supported by in vitro studies, animal models and hundreds of
observational studies. One randomized study investigated a role of
presumed suppressive effects of leukocyte-containing transfusions compared
to leukocyte-depleted filtered transfusions on recurrence of colorectal
cancer after surgery with curative intent. This study found no difference
in cancer recurrence after 2 and 5 years follow-up7,8.Most clinically
manifest cancers and metastasis do not elicit an effective immune response
as tumor cells can downregulate allele-specific HLA antigens, escaping T
cell and NK cells. Furthermore, blood transfusions during surgery come in
a late phase of the disease, when immunosurveillance already had its
chance, and failed. A role for transfusions in the development of new
malignancies is especially suggested with subtypes of non-Hodgin
lymphoma9. However, this association may be caused by reverse causality10.
Transfusions and postoperative nosocomial infections The possible effect
of blood transfusions on the incidence of postoperative infections is
widely researched7,11-18. So far this has lead to a large number of
publications, several randomized controlled trials (RCTs) and fierce
discussions19-23. The vast majority of published studies are observational
and compare transfused with non-transfused patients. This design makes
them unsuitable to inform on causal relationships, as infections are
associated with anemia. Multivariate analyses reduced the number of
significant correlations reported, but even the use of multivariate
analyses can never fully correct for the inclusion bias where all patients
have a clinical transfusion indication in one group versus none in the
other group. Several meta-analyses were performed, mainly on the RCTs, in
an attempt to gain more insight in this matter. However, all were hampered
by several factors: 1) Different types of surgical patients were included.
2) Different definitions were used for postoperative infections. 3)
Different blood products were used. 4) Different analyses were reported by
the authors. These differences resulted in the reporting of odds ratios
ranging from <1 to >14, clearly indicating that the studies did not report
on similar situations. Furthermore, there is publication bias, as the
smaller RCTs reported in literature show more pronounced detrimental
effects of leukocyte containing transfusions than the larger RCTs. Authors
of meta-analyses tried various ways to adjust for all these variations,
resulting in different conclusions in metaanalyses based on the same
studies. Of two simultaneously updated meta-analyses, one reports a
significant odds ratio of 1.92 (95% CI, 1.22-3.01) focusing on transfused
patients only, whilst the other one reports a non-significant odds ratio
of 1.24 (95% CI, 0.98-1.56) following analysis according to
intention-to-treat19,24. With such results, an effect of transfusion on
postoperative infections cannot be considered proven, but it definitely
cannot be excluded either. Transfusions and multi-organ failure and
mortality There is an increasing amount of evidence that in specific
patient groups blood transfusions may increase the incidence and/or
mortality rate of multi-organ failure (MOF). The introduction of leukocyte
reduction for all transfusions was used in several countries to perform
before/after studies. Some of these studies reported a beneficial effect
of leukoreduced blood on mortality25,26. Other observational studies
reported transfusions as an independent risk factor for SIRS, MOF and
mortality27-31. Like with postoperative infections, the limitations of the
observational design prevent any definitive conclusion on a causal
relationship. Most of the RCTs reporting on mortality investigated the
effect of leukoreduction by filtration. An association of non-filtered
blood transfusions with mortality was only reported in some of the cardiac
surgery studies. Of the RCTs investigating the use of autologous blood,
none reported a beneficial effect on mortality. Conclusions On one hand
transfusion-related immunomodulation is a concept that is very attractive
to exploit as specific toleranceinducing conditioning prior to organ
transplantation; on the other hand, transfusion-related immunosuppression
enhancing cancer recurrence, infections and mortality is a serious concern
that has led to wide implementation of universal leukocyte reduction of
red blood cell transfusions. A deleterious role of leukocyte-containing
transfusions has only been demonstrated in cardiac surgery. This might be
related to the effects of extracorporeal circulation and reperfusion
injury leading to SIRS, with transfusions disturbing, as a second hit, the
shaky balance of the recovery process.

Abstract
Glycoprotein (GP) IIb\IIIa receptor plays a central role on platelets
activation and its blockage has been a matter of interest since the
beginning of percutaneous revascularization. After first promising trials,
GP IIb\IIIa inhibitors (GPI) have been widely used in cath labs for about
a decade, significantly improving prognosis for patients with STSegment
Elevation Myocardial Infarction (STEMI). However, their utilization isn't
exempt from risks, mainly in form of bleeding disorders, which can
negatively affect patients' outcome. Moreover, routinary administration of
thyenopiridines like clopidogrel and the introduction of new
anticoagulants like bivalirudin significantly reduced indications for GPI.
In this review, a risk/benefit evaluation GP IIb\IIIa inhibitors is
presented and their indications for STEMI patients addressed to
revascularization are discussed according to recent advances reported in
literature. 2012 Bentham Science Publishers.

Abstract
Introduction and Aims: Novel biomarkers (BM) may aid in early diagnosis of
acute kidney injury (AKI), prediction of AKI severity and adverse
outcomes. As such, one potential clinical application is early
identification of AKI patients who will need renal replacement therapy
(RRT). Our aim was to evaluate the performance of novel BMs for the
prediction of RRT. Methods: We performed a systematic review of
Medline/PubMed to identify novel BM studies which reported RRT as an
outcome, whether separate or part of a composite. Studies which reported
area under the receiver operating characteristic curve (AuROC) and/or
sensitivity/ specificity for any outcome which included RRT were eligible
for full review; we excluded those related to renal transplant. Data were
extracted on study design and quality, population characteristics, and
incidence of RRT and outcomes on standardized case report forms. Primary
outcome was prediction of RRT. Whenever possible, data on RRT alone was
abstracted from composite outcomes. Results: We identified 30 studies (27
prospective cohort, 2 retrospective, 1 RCT), representing a total of 6631
patients (RRT, n= 791 patients). Studies were performed in diverse
clinical settings: cardiac surgery (CS, n=4 studies), critical illness
(ICU, n=9), CS&ICU (n=2), hospital AKI (n=9), other (n=6); sample sizes
ranged from 19-635. Urinary and blood BMs were evaluated in 20 and 17
studies, respectively; 10 evaluated multiple BMs. The most commonly
studied BMs were NGAL (n=18), cystatin C (n=11), KIM-1 (n=5) and IL-18
(n=4). AuROC for RRT or the composite of RRT/death were reported in 12 and
3 studies, respectively. The range of AuROC was <0.66-0.95 for NGAL,
0.62-0.99 for cystatin C (Table 1), 0.62-0.65 for KIM-1 and 0.73 for
IL-18. Specific biomarker cut-offs for RRT decisions were poorly reported.
Conclusions: Evidence regarding novel BM performance for predicting RRT is
(Table Presented) highly heterogeneous. The reported AuROCs exhibit a wide
range, even within a single BM. This is likely related to multiple factors
including clinical setting, comorbidities, timing of specimen collection,
type of specimen and assay, among others. Further studies are needed to
decipher the utility of these BMs in predicting RRT, and to clarify the
optimal biomarker values for informing clinical management decisions.

Abstract
Perioperative hyperglycemia is common in patients with type 2 diabetes
undergoing Coronaiy Arteiy Bypass Graft (CABG) surgery and there is a
direct relation between postoperative hyperglycemia and mortality rate in
these patients. The aim of the present study is to determine the efficacy
of metformin on glycemic control in diabetic patients after CABG surgery.
In a randomized double blind clinical trial, 100 patients with type 2
diabetes admitted in open heart ICU after CABG surgeiy in Mazandaran Heart
Center were enrolled. They were randomly assigned to two intervention and
control groups. Three hours after extubation, therapeutic antiglycemic
regimens were applied in these two groups and continued for three days.
Intervention group received regular insulin infusion along with two
metformin 500 mg tablets per twelve hours while control group received
regular insulin infusion with two placebo tablets per twelve hours. Blood
glucose level and other parameters were measured andrecorded in determined
intervals. To analyze the data, independent T-test, paired T-test,
Mann-Whitney and repeated measure ANOVA tests were employed. Mean blood
glucose level was not significantly different in the two groups at the
beginning of the ICU admission; however, mean glucose level in
insulin-metformin group, twelve hours after the initiation of the study,
was significantly lower than insulin group (p<0.05). In addition, mean
doses of potassium and insulin demand as well as mean number of episodes
of hyperglycemia, hypoglycemia and glucose levels out of the accepted
range were significantly lower in insulin-metformin group (p<0.05).
Alterations in mean levels of lactate, BE, pH and creatinine were not
statistically significant in these two groups. It seems that adding
metformin to insulin leads to a better glycemic control in type two
diabetic patients undergoing CABG surgeiy without causing metabolic
acidosis. Therefore, it might be a potential option in blood glucose
control protocol in this group of patients. 2011 asian network for

Abstract
Background-The clinical significance of incomplete coronary
revascularization (ICR) after percutaneous coronary intervention in
patients with acute coronary syndromes is unknown. Methods and Results-We
performed quantitative angiography of the entire coronary tree in 2954
patients with acute coronary syndromes in the Acute Catheterization and
Urgent Intervention Triage Strategy (ACUITY) trial. ICR was variably
defined if any lesion with diameter stenosis (DS) cutoffs ranging from
>=30% to >=70% with reference vessel diameter 2.0 mm remained after
percutaneous coronary intervention. The primary outcome was 1-year
composite rate of major adverse cardiac events (death, myocardial
infarction, or ischemia-driven unplanned revascularization). With the use
of DS cutoffs >=30%, >=40%, >=50%, >=60%, and >=70%, the prevalence of ICR
after percutaneous coronary intervention was >=75%, >=55%, >=37%, >=25%,
and >=17%, respectively. The 1-year major adverse cardiac event rate was
increased among patients with ICR using all of the DS cutoffs. ICR (>=50%
DS) was associated with higher 1-year rates of myocardial infarction
(12.0% versus 8.2%; hazard ratio, 1.50; 95% confidence interval,
1.18-1.89; P=0.0007) and ischemia-driven unplanned revascularization
(15.7% versus 10.2%; hazard ratio, 1.58; 95% confidence interval,
1.28-1.96; P<0.0001), with a trend toward increased mortality (3.1% versus
2.2%; hazard ratio, 1.43; 95% confidence interval, 0.90-2.27; P=0.13). By
multivariable analysis, ICR (50% DS) was an independent predictor of
1-year major adverse cardiac events (hazard ratio, 1.36; 95% confidence
interval, 1.12-1.64; P=0.002). The impact of ICR on major adverse cardiac
events was similar regardless of chronic total occlusion presence, but it
was more pronounced with a greater number of nonrevascularized lesions.
Conclusions-Depending on the threshold of percent DS, ICR was present in
17% to 75% of patients with acute coronary syndromes after percutaneous
coronary intervention. Regardless of the threshold, ICR was strongly
associated with 1-year myocardial infarction, ischemia-driven unplanned
revascularization, and major adverse cardiac events. Clinical Trial

Abstract
Background: Left ventricular (LV) remodeling predicts poor outcomes in
heart failure (HF) patients. The HeartNet cardiac restraint device
(Paracor Medical Inc., Sunnyvale, CA) may reduce LV remodeling and improve
functional capacity, quality of life, and outcomes in HF patients. To
evaluate the safety and efficacy of the HeartNet Ventricular Support
System in HF patients receiving optimal medical therapy. Methods and
Results: Prospective, randomized, controlled, multicenter trial in
patients with symptomatic HF and LV ejection fraction <=35% on optimal
medical and device therapy. The primary efficacy end points were changes
in peak VO<sub>2</sub>, 6-minute walk (6MW) distance, and Minnesota Living
with Heart Failure (MLWHF) quality of life score at 6 months. The primary
safety end point was all-cause mortality at 12 months. Because the planned
adaptive interim analysis of the first 122 subjects with a completed
6-month follow-up indicated futility to reach the peak VO<sub>2</sub> end
point, trial enrollment was suspended. Hence, the results on the 96
treatment and 114 control subjects are reported. Groups were similar at
baseline. At 6 months, responder frequency for a prespecified improvement
was similar between groups for peak VO<sub>2</sub> (P =.502) and MLWHF
score (P =.184) but borderline higher for improvement in 6MW distance in
the treatment compared with the control group (33 [38%] vs. 25 [25%]; P
=.044). At 6 months, the treatment group had a significantly greater
improvement in Kansas City Cardiomyopathy Questionnaire (KCCQ) (P < .001)
and decrease in LV mass (P =.032), LV end-diastolic diameter (P =.015), LV
end-systolic diameter (P =.032), and LV end-diastolic volume (P =.031) as
compared with controls. At 12 months, all-cause mortality and responder
rates were similar in the 2 groups. Success rate for the HeartNet
implantation was 99%. Conclusion: Enrollment in the trial was stopped
because an interim analysis showed futility of reaching the peak
VO<sub>2</sub> end point. However, because of the device safety and
favorable signals for LV remodeling and quality of life, further
investigation of this device is warranted. 2012 Elsevier Inc. All rights

Abstract
Background: Cumulative dose-dependent nonischemic cardiomyopathy (NICM)
remains a significant risk with the use of some chemotherapeutic agents.
In this context, omega-3 polyunsaturated fatty acids (PUFA) have been
investigated for their cardioprotective potential in rodent and in vitro
models of anthracycline toxicity, with conflicting results. This study
evaluated prophylactic omega-3 PUFA supplementation in a large-animal
model of anthracycline-induced NICM. Methods and Results: Merino sheep
were randomized to oral drenching with omega-3 PUFA (fish oil; n = 8) or
olive oil placebo (n = 9) 3 weeks before commencing repeated intracoronary
infusions of doxorubicin (DOX) to induce cardiac dysfunction. Cumulative
DOX dose was 3.6 mg/kg. Drenching was continued for 12 weeks after final
DOX exposure. Despite significant increases in tissue omega-3 PUFA levels
(P <.05 vs placebo), omega-3-treated sheep displayed greater signs of
anthracycline cardiotoxicity than placebo animals, consisting of left
ventricular dilatation and a greater decline in ejection fraction (P <
.05), although myocardial fibrosis burden was similar in both groups.
Conclusions: Dietary intake of omega-3 PUFA fails to prevent and may
indeed exacerbate DOX-induced cardiotoxicity. Clinical use of omega-3
supplementation during chemotherapy should be deferred until more
information is available regarding the mechanisms of interaction between
fatty acids and the myocardium during anthracycline exposure. 2012

Abstract
Background-Whether mitral valve repair during coronary artery bypass
grafting (CABG) improves survival in patients with ischemic mitral
regurgitation (MR) remains unknown. Methods and Results-Patients with
ejection fraction <=35% and coronary artery disease amenable to CABG were
randomized at 99 sites worldwide to medical therapy with or without CABG.
The decision to treat the mitral valve during CABG was left to the
surgeon. The primary end point was mortality. Of 1212 randomized patients,
435 (36%) had none/trace MR, 554 (46%) had mild MR, 181 (15%) had moderate
MR, and 39 (3%) had severe MR. In the medical arm, 70 deaths (32%)
occurred in patients with none/trace MR, 114 (44%) in those with mild MR,
and 58 (50%) in those with moderate to severe MR. In patients with
moderate to severe MR, there were 29 deaths (53%) among 55 patients
randomized to CABG who did not receive mitral surgery (hazard ratio versus
medical therapy, 1.20; 95% confidence interval, 0.77-1.87) and 21 deaths
(43%) among 49 patients who received mitral surgery (hazard ratio versus
medical therapy, 0.62; 95% confidence interval, 0.35-1.08). After
adjustment for baseline prognostic variables, the hazard ratio for CABG
with mitral surgery versus CABG alone was 0.41 (95% confidence interval,
0.22-0.77; P=0.006). Conclusion-Although these observational data suggest
that adding mitral valve repair to CABG in patients with left ventricular
dysfunction and moderate to severe MR may improve survival compared with
CABG alone or medical therapy alone, a prospective randomized trial is
necessary to confirm the validity of these observations. Clinical Trial
