Abstract
Introduction: Cardiac surgery is associated with post-operative reductions
of functional residual capacity (FRC). Manual hyperinflation (MH) aims to
prevent airway plugging, and as such could prevent the reduction of FRC
after surgery. The main purpose of this study was to determine the effect
of MH on post-operative FRC of cardiac surgical patients.Methods: This was
a randomized controlled trial of patients after elective coronary artery
bypass graft and/or valve surgery admitted to the intensive care unit
(ICU) of a university hospital. Patients were randomly assigned to a
"routine MH group" (MH was performed within 30 minutes after admission to
the ICU and every 6 hours thereafter, and before tracheal extubation), or
a "control group" (MH was performed only if perceptible (audible) sputum
was present in the larger airways causing problems with mechanical
ventilation, or if oxygen saturation (SpO₂) dropped below 92%).
The primary endpoint was the reduction of FRC from the day before cardiac
surgery to one, three, and five days after tracheal extubation. Secondary
endpoints were SpO₂(at similar time points) and chest
radiograph abnormalities, including atelectasis (at three days after
tracheal extubation).Results: A total of 100 patients were enrolled.
Patients in the routine MH group showed a decrease of FRC on the first
post-operative day to 71% of the pre-operative value, versus 57% in the
control group (P = 0.002). Differences in FRC became less prominent over
time; differences between the two study groups were no longer
statistically significant at Day 5. There were no differences in SpO₂between the study groups. Chest radiographs showed more
abnormalities (merely atelectasis) in the control group compared to
patients in the routine MH group (P = 0.002).Conclusions: MH partly
prevents the reduction of FRC in the first post-operative days after
cardiac surgery.Trial registration: Netherlands Trial Register (NTR):

Abstract
Introduction: Patients undergoing coronary revascularization often require
inotropic support that has been associated with an increased risk for
death and morbidity. The purpose of this study was to evaluate the effect
of levosimendan versus control on survival after coronary
revascularization.Methods: A systemic review and meta-analysis of the
literature was carried out on published randomized controlled clinical
trials that investigated the efficacy of levosimendan compared to other
therapy in patients having coronary revascularisaion. The databases
searched were Pubmed, EMBASE, the Cochrane Registry of Clinical Trials and
the metaRegister of Controlled Trials. Studies that compared levosimendan
to any other therapy for coronary revascularisation in adult humans and
reported at least one outcome of interest were considered for inclusion.
Both percutaneous coronary intervention and cardiac surgery were included.
Data extraction was performed independently by two reviewers using
predefined criteria. Relevant outcomes included mortality, cardiac index,
cardiac enzymes, length of stay and post-procedural atrial
fibrillation.Results: The meta-analysis included 729 patients from 17
studies. Levosimendan was associated with a mortality reduction after
coronary revascularization, (19/386 in the levosimendan group vs 39/343 in
the control arm) odds ratio (OR) 0.40 (95% confidence interval (CI) 0.21
to 0.76, P for overall effect 0.005, P for heterogeneity = 0.33, I²= 12% with a total of 729 patients. Levosimendan also had a
favourable effect on cardiac index (standardised mean difference 1.63, 95%
CI 1.43 to 1.83, P for overall effect < 0.00001), length of intensive care
stay (random effects model, mean difference - 26.18 hours 95% CI 46.20 to
6.16, P for heterogeneity < 0.00001, I²= 95%, P for overall
effect P = 0.01), reductions in the rate of atrial fibrillation (OR 0.54,
95% CI 0.36 to 0.82, P for effect = 0.004, P for heterogeneity 0.84,
I²= 0% for 465 patients) and troponin I levels group (mean
difference -1.59, 95% CI 1.78 to 1.40, P for overall effect < 0.00001, P
for heterogeneity < 0.00001, I²= 95%). Limitations of this
analysis are discussed.Conclusions: Levosimendan is associated with a
significant improvement in mortality after coronary revascularization.
There are also improvements in several secondary endpoints. A suitably
powered randomised controlled trial is required to confirm these findings
and to address the unresolved questions about the timing and dosing of
levosimendan. 2011 Maharaj and Metaxa; licensee BioMed Central Ltd.

Abstract
Objective: Although previous studies have demonstrated that modified
ultrafiltration improves laboratory parameters in pediatric cardiac
surgery, the clinical outcome data have been inconsistent. We performed a
meta-analysis of randomized controlled trials comparing modified versus
conventional ultrafiltration. Methods: We conducted a comprehensive search
of the literature to identify clinical trials that met our inclusion
criteria. To be included, studies had to be prospective randomized trials
that compared modified ultrafiltration and conventional ultrafiltration in
pediatric cardiac surgery using cardiopulmonary bypass. We focused on the
following outcome variables: hematocrit and mean arterial blood pressure
after cardiopulmonary bypass, amount of chest tube drainage after surgery,
time to extubation, and length of stay in the intensive care unit. The
random effects model was used to determine the pooled effect estimates.
The estimators of treatment effects were expressed as the weighted mean
difference with 95% confidence intervals. The heterogeneity of collected
data was also evaluated. Results: We screened 54 studies, 8 of which
satisfied our inclusion criteria. Combined analysis revealed that modified
ultrafiltration resulted in significantly higher postbypass hematocrit and
higher mean arterial blood pressure. Benefits in postoperative blood loss,
ventilator time, and intensive care unit stay were not apparent. There was
significant heterogeneity among the studies surveyed. Conclusions: The
advantage of modified ultrafiltration over conventional ultrafiltration
consists of significant improvement of clinical conditions in the
immediate postbypass period. The postoperative outcome parameters were not
significantly influenced. We should also take into account possible
clinical or methodologic variations in the currently available
ultrafiltration studies. 2011 by The American Association for Thoracic

Abstract
Objective: Experimental and clinical studies have suggested that
intramyocardial bone marrow stem cell transplantation combined with
coronary artery bypass grafting might improve left ventricular function in
the setting of chronic ischemic heart disease. We therefore conducted a
systematic review and meta-analysis of available publications regarding
the efficacy and safety of intramyocardial bone marrow stem cell
transplantation during coronary artery bypass grafting. Methods: The
databases PUBMED, MEDLINE, Cochrane Controlled Trials Register, and
ClinicalTrials.gov (all from their inception to May 2009) were searched
for randomized controlled trials and cohort studies of intramyocardial
bone marrow stem cell transplantation during coronary artery bypass
grafting to treat ischemic heart disease. Six studies were included.
Results: Compared with control groups, the bone marrow stem cell
transplantation group showed a significant improvement of left ventricular
ejection fraction from baseline to follow-up (5.40%; 95% confidence
interval, 1.36-9.44; P = .009). Moreover, the overall change of left
ventricular end-diastolic volume from baseline to follow-up favored the
bone marrow stem cell therapy group (9.55 mL; 95% confidence interval,
-2.82 to 21.92; P = .13). Major adverse cardiovascular events, including
ventricular arrhythmia and the composite of other cardiovascular events,
were not significantly different between the bone marrow stem cell therapy
group and controls (relative risk for ventricular arrhythmia = 0.951; 95%
confidence interval, 0.389-2.325; P = .913; relative risk for
cardiovascular event = 1.134; 95% confidence interval, 0.28-4.6; P = .86).
Conclusions: Clinical evidence suggests that intramyocardial bone marrow
stem cell transplantation in combination with coronary artery bypass
grafting is associated with improvements of functional parameters in
patients with chronic ischemic heart disease. Furthermore, surgical
intramyocardial bone marrow stem cell transplantation seems to be safe.

Abstract
Objectives: We sought to compare long-term outcomes after coronary bypass
surgery with and without an internal thoracic artery graft. Methods: We
analyzed clinical outcomes over a median follow-up of 6.7 years among
3,087 patients who received coronary bypass surgery as participants in one
of 8 clinical trials comparing surgical intervention with angioplasty. We
used 2 statistical methods (covariate adjustment and propensity score
matching) to adjust for the nonrandomized selection of internal thoracic
artery grafts. Results: Internal thoracic artery grafting was associated
with lower mortality, with hazard ratios of 0.77 (confidence interval,
0.62-0.97; P = .02) for covariate adjustment and 0.77 (confidence
interval, 0.57-1.05; P = .10) for propensity score matching. The composite
end point of death or myocardial infarction was reduced to a similar
extent, with hazard ratios of 0.83 (confidence interval, 0.69-1.00; P =
.05) for covariate adjustment to 0.78 (confidence interval, 0.61-1.00; P =
.05) for propensity score matching. There was a trend toward less angina
at 1 year, with odds ratios of 0.81 (confidence interval, 0.61-1.09; P =
.16) in the covariate-adjusted model and 0.81 (confidence interval,
0.55-1.19; P = .28) in the propensity score-adjusted model. Conclusions:
Use of an internal thoracic artery graft during coronary bypass surgery
seems to improve long-term clinical outcomes. 2011 by The American

Abstract
Objective: In this meta-analysis, data from relevant randomised controlled
trials has been pooled together to gain a consensus in the comparison of
outcome following hand-sewn versus stapled oesophago-gastric (OG)
anastomoses. Methods: Medline, Embase, Cochrane, trial registries,
conference proceedings and reference lists were searched for randomised
controlled trials comparing hand-sewn and stapled OG anastomoses. Primary
outcome measures were 30-day mortality, anastomotic leakage and stricture.
Secondary outcomes were operative time, cardiac complications and
pulmonary complications. Results: Nine randomised trials were included in
this meta-analysis. There was no significant difference between the groups
for 30-day mortality (pooled odds ratio = 1.71; 95% CI = 0.822 to 3.56; P
= 0.15) and anastomotic leakage (pooled odds ratio = 1.06; 95% CI = 0.62
to 1.80; P = 0.83). There was a significantly increased rate of
anastomotic stricture associated with stapled OG anastomosis (pooled odds
ratio = 1.76; 95% CI = 1.09 to 2.86; P = 0.02). Discussion: Meta-analysis
of randomised controlled trials comparing hand-sewn with stapled OG
anastomosis demonstrates that a stapled anastomosis is associated with a
shorter operative time but with an increased rate of post-operative
anastomotic stricture. 2011 The Society for Surgery of the Alimentary

Abstract
The optimal timing of surgical intervention in patients with asymptomatic
severe mitral regurgitation remains controversial, because the potential
benefits of early surgery need to be balanced against the operative risks.
As prediction of mitral valve repair has become clinically feasible, and
mitral valve repair has shown excellent long-term results, there is an
increasing need for direct comparison between watchful waiting and early
mitral valve repair. We prospectively evaluated 447 consecutive
asymptomatic patients with severe degenerative mitral regurgitation and
preserved left ventricular function to compare clinical outcomes of early
surgery with those of the conventional treatment strategy. Early surgery
was performed on 161 patients and the conventional treatment strategy on
286 patients. In the early surgery group, mitral valve repair and
replacement were performed successfully in 151 (94%) and 10 (6%) patients,
respectively, without operative mortality. This study demonstrates that in
asymptomatic patients with severe degenerative mitral regurgitation and
preserved left ventricular function, early surgery is associated with
improved long-term clinical outcomes compared with the conventional
treatment strategy by decreasing cardiac mortality and hospitalization due
to congestive heart failure. We therefore suggest that early surgery may
further improve clinical outcomes in asymptomatic severe mitral
regurgitation with a high likelihood of mitral valve repair. Further
prospective, randomized studies are needed to confirm the efficacy of
early surgery. Conclusions: Compared with conservative management, the
strategy of early surgery was associated with an improved long-term event
rate by decreasing cardiac mortality and congestive heart failure
hospitalization more effectively in patients with severe degenerative
mitral regurgitation. Early surgery may therefore further improve clinical
outcomes in asymptomatic severe mitral regurgitation with preserved left
ventricular systolic function and a high likelihood of mitral valve
repair.¹ coronary interventions (PCI), bypass surgery (CABG),
or a combination of these strategies. It is unknown which treatment
approach is best for specific patient subgroups. Here, we report 10-year
follow-up of the second Medicine, Angioplasty, or Surgery Study (MASS II),
a study that evaluated MT alone, PCI, or CABG among stable coronary
patients with multivessel disease. No differences were observed in overall
mortality in patients treated with CABG, PCI, or MT. Nevertheless,
compared with CABG, MT was associated with a significantly higher
incidence of cardiac death, subsequent myocardial infarction, and
additional revascularization. Overall, compared with CABG, MT was
associated with a 2.29-fold increased risk of combined events. Event rates
for PCI patients were intermediate between MT and CABG. Indeed, by finding
the lowest rate of further interventions in the CABG group, our results
support a strategy of revascularization, and in particular CABG, in
addition to MT for selected stable coronary patients with multivessel
disease. Conclusions: Compared with CABG, MT was associated with a
significantly higher incidence of subsequent myocardial infarction, a
higher rate of additional revascularization, a higher incidence of cardiac
death, and consequently a 2.29-fold increased risk of combined events. PCI
was associated with an increased need for further revascularization, a
higher incidence of myocardial infarction, and a 1.46-fold increased risk
of combined events compared with CABG. Additionally, CABG was better than
MT at eliminating anginal symptoms.². 2011 American Heart

Abstract
Embolism of cardiac origin accounts for about 20 of ischemic strokes.
Nonvalvular atrial fibrillation is the most frequent cause of
cardioembolic stroke. Approximately 1 of population is affected by atrial
fibrillation, and its prevalence is growing with ageing in the modern
world. Strokes due to cardioembolism are in general severe and prone to
early recurrence and have a higher long-term risk of recurrence and
mortality. Despite its enormous preventive potential, continuous oral
anticoagulation is prescribed for less than half of patients with atrial
fibrillation who have risk factors for cardioembolism and no
contraindications for anticoagulation. Available evidence does not support
routine immediate anticoagulation of acute cardioembolic stroke.
Anticoagulation therapy's associated risk of hemorrhage and monitoring
requirements have encouraged the investigation of alternative therapies
for individuals with atrial fibrillation. New anticoagulants being tested
for prevention of stroke are low-molecular-weight heparins (LMWH),
unfractionated heparin, factor Xa inhibitors, or direct thrombin
inhibitors like dabigatran etexilate and rivaroxaban. The later exhibit
stable pharmacokinetics obviating the need for coagulation monitoring or
dose titration, and they lack clinically significant food or drug
interaction. Moreover, they offer another potential that includes fixed
dosing, oral administration, and rapid onset of action. There are several
concerns regarding potential harm, including an increased risk for
hepatotoxicity, clinically significant bleeding, and acute coronary
events. Therefore, additional trials and postmarketing surveillance will
be needed. Copyright 2011 M. ngels Font et al.

Abstract
Cardiac surgery with aid of cardiopulmonary bypass (CPB) is associated
with neurological dysfunction. The presence of cerebrospecific protein
S100 in serum is an indicator of cerebral damage. This study was designed
to evaluate the influence of three different anesthesia techniques, on
S100 levels, in patients undergoing coronary artery bypass grafting on
CPB. A total of 180 patients were divided into three groups-each of who
received sevoflurane, isoflurane and total intravenous anesthesia as part
of the anesthetic technique, respectively. S100 were evaluated from venous
sample at following time intervals-prior to induction of anesthesia (T1),
after coming off CPB (T2); 12 h after aortic cross clamping (T3) and 24 h
after aortic cross clamping (T4). In all three groups, maximal rise in
S100 levels occurred after CPB which gradually declined over next 24 h,
the levels at 24 h post-AOXC being significantly higher than baseline
levels. Significantly low levels of S100 were noted at all postdose hours
in the sevoflurane group, as compared to the total intravenous anesthesia
(TIVA) group, and at 12 and 24 h postaortic cross clamp, in comparison to
the isoflurane group. Comparing the isoflurane group with the TIVA group,
the S100 levels were lower in the isoflurane group only at 24 h postaortic
cross clamp. It was concluded that maximum rise in S100 levels occurs
immediately after CPB with a gradual decline in next 24 h. The rise in
S100 levels is significantly less in patients administered sevoflurane in
comparison to isoflurane or TIVA. Hemodynamic parameters had no influence
on the S100 levels during the first 24 h after surgery.

Abstract
Post-cardiac surgery acute kidney injury (AKI) is common and is associated
with a significant increase in morbidity and mortality. We aimed to
systematically review randomised trials that assessed the renoprotective
utility of pharmacological agents in patients undergoing cardiac surgery.
We searched PubMed, Embase and the Cochrane Central Register of Controlled
Trials for randomised controlled trials comparing renoprotective
pharmacological interventions with control in adult patients undergoing
cardiac surgery with cardiopulmonary bypass. We extracted data for
mortality, need for renal replacement therapy (RRT), incidence of AKI, and
creatinine clearance at 24-48 h. About 49 randomised controlled trials
involving 4605 patients were included. Pharmacological interventions
included dopamine, fenoldopam, calcium channel antagonists, natriuretic
peptides, diuretics, and N-acetylcysteine. Most trials were of poor
quality, with small sample sizes, under-reporting of randomisation
procedure, allocation concealment and method of blinding. No
pharmacological intervention significantly reduced mortality. Fenoldopam
and Atrial Natriuretic Peptide (ANP) reduced the need for renal
replacement therapy by 5% (NNT 20, 95% CI 11.3, 83.0) and 3.5% (NNT 29,
95% CI 17.1, 84.4), respectively. Brain Natriuretic Peptide resulted in a
10% reduction in the incidence of AKI (NNT 11, 95% CI 6.2, 32.0). Dopamine
caused a significant reduction in creatinine clearance (-4.26 ml/min, 95%
CI -7.14, -1.39). The quality of studies that have assessed
pharmacological renoprotective agents in cardiac surgery is generally
poor. Fenoldopam, ANP and BNP show evidence of renoprotection. Randomised
studies evaluating the effect of novel renoprotective agents that are
powered to detect clinically relevant differences in outcomes are
required. 2011 Springer Science+Business Media, LLC.

Reduced glomerular filtration rate (GFR) is associated with adverse
outcomes in patients with cardiovascular disease. We explored the
relationship between GFR and angiographic and clinical outcomes in
ST-segment elevation myocardial infarction (STEMI) patients receiving
pharamacologic reperfusion, with or without clopidogrel. Data were
available to estimate GFR in 3,252 STEMI patients undergoing fibrinolysis,
randomized to clopidogrel versusplacebo in the CLARITY-TIMI 28 trial.
Patients with a creatinine >2.5 mg/dl were excluded from the trial. We
compared outcomes between patients with no, mild or moderate reductions in
baseline estimated GFR (ml/min/1.73 m²) of >=90, 60-89, and
<60, respectively. Compared to patients with no (n = 841) or mildly
reduced GFR (n = 1897), those with moderately reduced GFR (n = 514) were
older, more often female, and were more likely to have diabetes and
hypertension (P <= 0.001 for all). The risk of the primary endpoint (an
occluded infarctrelated artery on angiography or death/myocardial
infarction by day 8), 30 day cardiovascular events (death, myocardial
infarction, or urgent revascularization for recurrent ischemia) and 30 day
Thrombolysis in Myocardial Infarction (TIMI) major or minor
bleedingincreased as GFR declined (P for trend 0.003,<0.0001, and 0.0008
respectively). The adjusted risk of 30 day ischemic complications remained
higher in patients with moderately reduced versus normal GFR (OR 1.5, 95%
CI 1.0-2.1, P = 0.04). Treatment with clopidogrel tended to yield greater
benefit in patients with normal or mildly reduced GFR versus in patients
with moderately reduced GFR. In conclusion, STEMI patients with reduced
GFR treated with medical reperfusion, including dual antiplatelet therapy,
have higher rates of adverse clinical outcome. Further research on optimal
STEMI therapy in this high-risk group is warranted. Springer

Abstract
Purpose. The effect of ascorbic acid on inflammatory markers after
cardiothoracic surgery (CTS) was studied. Methods. In this randomized,
doubleblind, placebo-controlled trial, patients undergoing cardiopulmonary
bypass graft surgery or valve replacement surgery from April 2009 through
March 2010 at Hartford Hospital were randomized to receive ascorbic acid
(2-g loading dose followed by 500 mg every 12 hours) or matching placebo
the evening before surgery and for four days postoperatively. Inflammatory
mediators were measured preoperatively and on postoperative days 1-4.
Intergroup comparisons were performed using two-tailed t tests and
Fisher's exact test. Multiple comparisons were conducted using repeated
analyses of variance with Bonferroni tests. Results. Of the 62 patients
screened, 24 met the study inclusion criteria. Of these, 13 were assigned
to receive ascorbic acid and 11 received placebo. Ascorbic acid did not
affect the natural course of inflammatory marker rise for C-reactive
protein (CRP)concentration, white blood cell (WBC) count, or fibrinogen
concentration versus placebo at any evaluated time point (p > 0.05 for all
intergroup comparisons). Intragroup analyses demonstrated significant
differences among baseline and postoperative measures of all inflammatory
mediators (p < 0.05). No significant differences were noted in
inflammatory markers between patients undergoing cardiothoracic surgery
with or without cardiopulmonary bypass, regardless of treatment group.
Conclusion. Ascorbic acid did not attenuate the rise in inflammatory
markers after CTS when compared with placebo. The use of off-pump surgery
did not significantly change the levels of CRP and fibrinogen or the WBC
count postoperatively when compared with on-pump surgery with a
biocompatible polymer coating. Copyright 2011, American Society of

Abstract
Open heart surgery is a procedure which warrants patient education about
the complexity of drug regimens and lifestyle modifications. Patient
nonadherence is likely to have a considerable negative impact on the
patients' quality of life postcardiac surgery. Objective: To evaluate the
impact of pharmacist intervention on patients' adherence to medication and
lifestyle changes. Method: This case-controlled study was conducted at the
Cardiac Surgical Ward and Outpatients Clinic of Mater Dei Hospital, Malta.
Eighty consecutive patients who underwent coronary artery bypass or heart
valve surgery were interviewed on their day of discharge using the 'Past
Medical History Questionnaire'. The patients were then randomized to
receive pharmacist intervention or usual care. Those who received
intervention (40 patients) were given a chart with pictorial explanation
of the time of day together with a colorful photograph of each tablet
prescribed. This group of patients was also counselled to comply to oral
analgesia and exercise and also on the avoidance of alcohol and smoking
during the recovery period. The control patients received usual care
without the pharmacist intervention. All patients were re-interviewed
eight weeks after discharge using the 'Assessing Patient Compliance
Questionnaire'. Any differences between the control and experimental
groups were analysed using Chi-square, Three-Way Cross tabulation One-Way
ANOVA and Two-Way ANOVA tests using the SPSS software version 17.0.
Results: A statistically significant difference between the two groups in
the mean percentage compliance was registered following pharmacist
intervention (p<0.05). Patients in the experimental group had a higher
mean percentage compliance score (88%) than patients in the control group
(66%). Conclusion: The statistically significant difference in the mean
percentage compliance between the two groups following pharmacist
intervention shows conclusive evidence of the advantage patients gain when
offered this intervention. The pharmacist intervention provides patients
with sufficient information to help them achieve optimal benefit from the
medication prescribed.

Abstract
Artrial fbrillation is the most common arrhythmia that occurs after
coronary bypass grafting operation with the rate of 30%. Atrial
fibrillation is associated with hemodynamic instability, strokes, and
prolonged hospital stay. Pericardial effusion is a risk factor for atrial
fbrillation after cardiac surgery, and it occurs commonly in the posterior
area during the post-operative period. The aim of this prospective study
was to demonstrate the effectiveness of posterior pericardiotomy in
reducing the incidence of atrial fibrillation. This prospective randomized
study was carried out on 425 patients undergoing a coronary artery bypass
grafting in our clinic between August 2009 and February 2011. There were
276 male patients and 149 female patients. These patients were randomly
divided into two groups; posterior pericardial incision was performed in
213 patients (pericardiotomy group), while any pericardial incision was
not performed in 212 patients (control group). Atrial fbrillation occurred
more frequently in control group (62 patients, 14.6%), compared to the
pericardiotomy group (14 patients, 3.1%; p < 0.0001). The incidences of
early pericardial effusion, late pericardial effusion, and tamponade were
also signifcantly higher in control group. Moreover, posterior
pericardiotomy was associated with the decreases in the duration of stay
in hospital and intensive care unit. In fact, the total hospital costs
were lower in the pericardiotomy group. In conclusion, posterior
pericardiotomy is an effective and safe technique that reduces early
pericardial effusion, atrial fbrillation, length of stay in hospital, and
hospital costs after the coronary artery bypasses grafting.

Title
Thrombocytopenia following implantation of the stentless biological sorin
freedom SOLO valve.
Source
The Journal of heart valve disease. 20 (4) (pp 401-406), 2011. Date of
Publication: Jul 2011.
Abstract
Stentless biological valves have proven advantages in hemodynamic
performance and left ventricular function compared to stented biological
valves. Following a marked postoperative fall in the platelet count of
patients after implantation of the Freedom SOLO valve, the study aim was
to confirm clinical observations that this effect was more severe in
patients receiving Freedom SOLO valves than in those receiving St. Jude
Medical (SJM) mechanical aortic valves. Preoperative and postoperative
platelet counts were compared in two groups of patients who underwent
aortic valve replacement (AVR) without any concomitant procedures between
January and December 2007. Patients received either a Freedom SOLO valve
(n = 28) or a SJM mechanical valve (n = 41). Mean values of platelet
counts were compared using three multiple linear regression models.
Platelet counts were significantly lower in the Freedom SOLO group than in
the SJM group from the first postoperative day (POD 1) up to POD 6 (p
<0.001). In three patients of the Freedom SOLO group the platelet count
fell below 30x10(9)/l, while the lowest level in the SJM group was
75x10(9)/l. Based on multiple linear regression models, the type of valve
implanted had a statistically significant influence on postoperative
platelet counts on POD 1, POD 3, and POD 5 (p <0.001). Whilst the reason
for this phenomenon is unknown, the use of consistent monitoring should
prevent severe falls in platelet count from becoming dangerous for the
patient. Further studies are required to investigate the phenomenon since,
despite a shorter cardiopulmonary bypass time, the fall in platelet count
was more profound in the Freedom SOLO group.

Abstract
Background: Treatment of the deceased heart-beating donor with low-dose
dopamine results in less dialysis requirement after kidney transplantation
and appears to improve the outcome after heart transplantation. This study
investigates the clinical course of liver allografts from multi-organ
donors that were enrolled in the randomized dopamine trial
(clinicaltrials.gov Identifier: NCT00115115). Methods: Between March 2004
and August 2007, 264 brain-dead donors were randomly assigned to receive
or to not receive low-dose dopamine. Elmugibility criteria included
circulatory stability under low-dose norepinephrine. The present study is
nested in the randomized controlled trial of donor pre-treatment with
dopamine. We assessed the outcomes of 197 liver transplants performed at
32 European centers. Results: Dopamine was infused at 4 mug/kg/min for a
median duration of 362 min (IQR 182 min). Donors and recipients were very
similar in baseline characteristics. Thirty-four recipients (16.8%) were
transplanted with high urgency and 23 (11.7%) received a repeat
transplant. Pretransplant MELD score was not different in recipients of a
dopamine treated versus untreated graft (18 +/- 8 vs. 19 +/- 9, P = 0.28).
Mean cold ischemic time was 632 +/- 172 vs. 600 +/- 170 min (P =0.20).
Following transplantation, no differences occurred in biopsy-proven
rejection episodes (15.3% vs. 17.2%, P =0.85), requirement of
hemofiltration (27.6% vs. 27.3%, P =0.99), and in-hospital mortality
(13.3% vs. 12.1%, P = 0.85). Graft survival was 72.5% vs. 74.8% and 61.2%
vs. 63.6% at 1 and 3 years. Conclusion: Contrasting heart and kidney
transplantation, donor pre-treat-ment with dopamine does not improve the
outcome after liver transplantation. Since liver cells specifically
express s-COMT with high activity, dopamine is rapidly degraded in-vivo,
which most likely abrogates its potential to protect the liver graft from
oxidative stress under cold storage conditions.

Abstract
Aims: Guidelines suggest patients should discontinue clopidogrel with a
washout of 5 days prior to coronary artery bypass grafting (CABG).
Concerns have focused on postoperative bleeding, transfusion requirements
and the need for reoperation. However, those with acute coronary syndrome
(ACS) are at elevated risk of further myocardial infarction and death
without clopidogrel while awaiting CABG. Therefore, operating on
clopidogrel is a necessary practice in many patients. This meta-analysis
aims to determine the risk of CABG specifically in ACS patients while
continuing clopidogrel. Method and results: 33 studies with 22,242
patients undergoing CABG were assessed. The majority were retrospective
with variable reporting of outcomes and demonstrated heterogeneity in
meta-analysis. ACS patients with recent clopidogrel exposure (CL) were
compared to those without recent clopidogrel (NC). Although mortality is
increased in CL compared to NC (OR 1.6, 95% CI 1.30-1.96, p<0.00001), it
is influenced by the ACS status of the patient in these mainly
nonrandomised studies. When ACS patients are specifically assessed, there
is no significant increase in mortality (OR 1.44,95% CI 0.97-2.1, p=0.07)
or in postoperative myocardial infarction (OR 0.57,95% CI 0.31-1.07,
p=0.08) and stroke rates (OR 1.23, 95% CI 0.66-2.29, p=0.52). Combined
MACE (stroke, MI and death) were not different in the two groups (OR 1.10,
95% CI 0.87-1.41, p=0.43). Transfusion rates showed marked heterogeneity
but more recent surgical cohorts demonstrate a reduction in post-operative
chest drain output and reoperation rates compared to earlier cohorts.
Reoperation rates were not specifically raised in ACS patients on
clopidogrel (OR 1.5, 95% CI 0.88-2.54, p=0.13 Conclusion: This
meta-analysis challenges our interpretation of previous studies that
suggest clopidogrel should be stopped prior to CABG. A washout period
delays surgery, and whilst warranted in elective patients, might be
detrimental in patients with ACS. Heterogeneity limits strong conclusions
but there is sufficient equipoise to suggest that clopidogrel should not
be discontinued in patients with ACS requiring urgent CABG, except in
those at highest operative bleeding risk. Importantly major endpoints were
not worse on clopidogrel. Heterogeneity in transfusion rates suggest it is
a weak outcome marker. Instead, improved reoperation rates over time
suggest there is improving skill in operating on clopidogrel. These
findings support the current practice of continuing clopidogrel until CABG
in many centres.

Abstract
Purpose: About 30% patients after coronary artery bypass graft (CABG)
developed atrial fibrillation (AF). Preoperative P-wave duration (POPWD)
has been suggested to be predictive of postoperative AF (POAF). It is
still controversial, however, regarding how well the POPWD predicts POAF.
We set out to examine the value of POPWD in predicting POAF among other
characteristics and combined our results with others in a meta-analysis.
Method: We prospectively studied 263 consecutive patients with normal
sinus rhythm (NSR) undergoing first-time elective isolated CABG. 12-lead
electrocardiogram was obtained preoperatively. Patients' demographic,
clinical and surgical characteristics were collected prospectively. The
main endpoint was the occurrence of first AF lasting >5 min. The patients
were classified as either NSR or AF group according to their postoperative
rhythm, which was continuously monitored for the first 7 postoperative
days. POPWD was analyzed with a commercial software by a research member
who was blinded to the patients' classification. Explanatory variables
with p<0.1 upon univariate analysis were entered into the logistic
regression model to assess the independent predictors of POAF. In
addition, we performed a meta-analysis to assess the combined effect of
POPWD in predicting POAF. Result: AF occurred in 85 (32.3%) of the 263
patients. With univariate analysis, older age (66.1+/-8.0 versus
60.6+/-9.4 years; p<0.001), prolonged POPWD (111.62+/-11.68 versus
101.16+/-10.79 ms; p<0.001), hypertension (p<0.05), aortic regurgitation
(p<0.01), and mitral regurgitation (p<0.05) were associated with POAF.
Multivariate analysis showed that only older age (odds ratio [OR] 1.06 per
year increment, 95% confidence intervals [CI] 1.02 - 1.10, p<0.01) and
POPWD >105 ms (OR 9.23, 95% CI 4.83 - 17.84, p<0.001) were independently
associated with the occurrence of POAF. Patients with AF could be
predicted by POPWD of longer than 105 ms, with specificity, positive and
negative predictive values of 72%, 76%, and 72%, respectively. The
meta-analysis combined our study with 10 other similar studies with a
total of 3207 patients. Overall, prolonged POPWD was associated with
greater risk of POAF, with a weighed mean difference of 4.76 ms (95% CI
2.62 - 6.90, p<0.01). Although there was significant heterogeneity across
the studies, after performing several sensitivity and subgroup analyses,
the analysis did not find a significant influence on the results.
Conclusion: This study confirmed that POPWD was a powerful independent
predictor of POAF among other predictive characteristics.

Abstract
Purpose: About 17.5% to 43% patients after coronary artery bypass graft
(CABG) deveoped atrial fibrillation (AF). Preoperative P-wave duration has
been suggested to predict the development of postoperative AF (POAF). It
is still controversial, however, regarding how well the P-wave duration
predicts POAF among other clinical characteristics. We evaluated the value
of preoperative Pwave duration in predicting AF and combined our results
with others in a metaanalysis study. Method: 263 consecutive patients with
sinus rhythm before surgery and scheduled to undergo CABG. 12-lead ECG,
echocardiogram and coronary angiography were obtained in all patients
before surgery. P-wave duration was analyzed with a commercially software
from the preoperative 12-lead ECG. ECGs were continuously monitored for
one week after CABG. The main endpoint of the study was the occurrence of
first AF lasting >=5 min. Patients were divided into two groups on the
basis of whether or not they developed POAF. All variables whose
univariate tests with a p value less than 0.1 were entered to a logistic
regression model to assess the independent predictors of AF. In addition,
we performed a meta-analysis to assess the combined value of P-wave
duration in predicting POAF. Result: AF occurred in 85 of the 263 patients
(32.3%), the average time from the operation to the first POAF episode was
2.4+/-1.5 days. With univariate analysis, older age (66.1+/-8.0 versus
60.6+/-9.4 years; p<0.001), prolonged P-wave duration (111.62+/-11.68
versus 101.16+/-10.79ms; p<0.001), hypertension (p<0.05), aortic
regurgitation (p<0.01) and mitral regurgitation (p<0.05) were associated
with POAF. Multivariate analysis showed that only older age (odds ratio
[OR] 1.06 per year increment, 95% confidence intervals [CI] 1.02 to 1.10,
p<0.01) and Pwave duration >105 milliseconds (ms; OR 9.23, 95% CI 4.83 to
17.84, p<0.001) were independently associated with the occurrence of POAF.
Patients with AF could be predicted by preoperative P-wave duration of
longer than 105ms, with a specificity of 72%, positive predictive value of
76%, and negative predictive value of 72%. The meta-analysis combined our
study with 8 other similar studies with a total of 1160 patients, using
random effects test. The 9 studies were heterogeneous (heterogeneity test:
Q2 = 45.98; p<0.001). The weighed mean difference in P-wave duration
between the patients with, and without POAF was 5.38 ms (95% CI 2.07 to
8.68, p<0.01). Conclusion: This study confirmed that preoperative P-wave
duration was a powerful independent predictor of POAF among other
predictive clinical characteristics.

Abstract
Purpose: Remote ischaemic conditioning (RIC) induced by transient upper
limb ischaemia attenuates myocardial injury in patients undergoing
percutaneous coronary intervention (PCI) and coronary artery bypass
grafting (CABG). Although the clinical trials examining RIC in these
settings have shown similar reductions in myocardial injury, there are
trials providing somewhat inconsistent results. Our aim is to assess the
effect of RIC in patients undergoing PCI and CABG. Methods: Medline,
Embase, and conference reports were searched for randomised trials of RIC
(defined as remote pre-, per- and postconditioning) in the setting of PCI
and CABG and were included if they reported on biomarkers of myocardial
injury (creatine kinase isoform-MB, troponin T or troponin I). From each
trial data were extracted using standardized forms where after
standardized mean differences (SMDs) were calculated for biomarkers of
myocardial injury using the Hedges g statistic. Results: Meta-analysis of
4 studies on PCI, comprising 557 patients, indicated reduced biomarkers
for myocardial injury in patients treated with RIC compared to control
(random effects model: SMD -0.21, 95% CI -0.66 to 0.24, P=0.36). The 8
CABG studies taken together, comprising 621 patients, revealed a
significant effect of RIC on myocardial injury (SMD -0.35, 95% CI -0.64 to
-0.05, P=0.02). The statistical tests indicated moderate to high
heterogeneity across the studies (Q-statistic: P=0.0006, I²=83%
and P=0.005, I²=66% for PCI and CABG, respectively). (Graph
presented) Conclusions: RIC with transient episodes of limb ischaemia in
patients undergoing PCI or CABG exhibits lower biomarkers of myocardial
injury compared to control. However, this effect failed to reach
statistical significance in the PCI analysis.

Abstract
Background: Coronary artery bypass graft (CABG) affects the functional
capacity, resulting in pulmonary complications. Respiratory Muscle
Training (IMT) in the preoperative period could be an effective
prophylactic feature. This controlled clinical trial intends to analyze
the effect of IMT on the functional capacity (FC), respiratory muscle
strength (RMS) and postoperative pulmonary complications. Method: Were
selected consecutively 32 individuals of both genders (65.6%men) referred
for CABG, with a high risk for pulmonary complications. The individuals
were randomized into Intervention Group (IG) and Control Group (CG).
Groups not differed by gender (IG 62.5% and CG 68.8%men), age (62+/-9.9 IG
and CG 62.0+/-10.9 years), LVEF (IG 87.5% and CG 75% >=50%), functional
class (IG 68.8% and CG 81.3% classified as NYHA II) and time of surgery
(IG 352.5 and CG 320.9minutes) (p=NS for all). There were four time
assessments: two weeks and one day before surgery, at three and seven days
after surgery. RMS was determined through manovacuometry analog, graduated
-120 to +120cmH2O, verified by maximum aspiratory and expiratory pressures
(MIP and MEP); FC was measured by the six-minute walk test (6MWT);
pulmonary complications was determined by Hulzebos' scale of risk (2006).
The IMT in IG was performed with the set ThresholdIMT, with workload 30%
of the MIP, during the two weeks prior to surgery, seven days a week,
twice a day, three sets of ten repetitions. Following descriptive
analysis, the results were compared by means of specific statistical
tests: chi-square, Fisher, Mann-Whitney test and MANOVA for repeated
measures. Results: During the preoperative period the MIP and FC in IG
increased 24.5% (70.0+/-19.7 and 92.7+/-26.8cmH2O, p<0.05) and 17% (6MWT
361.9+/-92.6 and. 434.4+/-89m, p<0.001) respectively, while in CG the MIP
decreased 12.3% (75.9+/-25.6 and 66.6+/-23,6cmH2O, p<0.001) and FC in 13%
(6MWT 384.8+/-136.3 and 333.7+/-116m, p<0.05), with significant difference
between groups (p<0.001). In relation to MEP was not observed significant
difference between groups (p=0.28). Postoperative MIP values (IG
63.4+/-14.3 and 74.1+/-20.3cmH2O, CG 58.7+/-15.7 and 64.1+/-19.2cmH2O,
p<0,001) and FC (IG 298.2+/-76.8 and 359.1+/-80.5m, CG 223.7+/-87.4 and
257.8+/-98.9m, p<0,001) showed less decreased and better recovery in IG.
In IG, pneumonia (IG 5.3% and CG 12.3%, p=0.04) and atelectasis (IG 18.7%
and CG 43.2%, p=0.02) occurred less. Conclusion: Preoperative IMT was
efficient in increasing respiratory muscle strength and FC, reducing the
incidence of postoperative pulmonary complications in patients undergoing
CABG.

Abstract
Purpose: It has been reported that women experience longer pre-hospital
delays for symptoms of acute coronary syndrome (ACS), than their male
counterparts. One xplanation for this delay is the suggestion that women
experience a different set of symptoms than men, some of which include
"atypical" symptoms. The purpose of this tudy was to examine whether
gender differences exist in the symptom experiences of women and men with
ACS. Methods: Symptom experience and medical profiles were ecorded for all
patients who participated in a large multi-centered randomized controlled
trial. Patients with ACS who were admitted to one of five major academic
teaching ospitals in Dublin, Ireland, with a diagnosis of ACS, were
enrolled in the study. Each patient was interviewed 2-4 days following
their admission and provided full details about the presence,
localization, onset and nature of their experienced symptoms. Details of
patients' medical profiles were obtained from patients' verbal reports and
edical chart review. Results: A total of 2037 patients, were initially
enrolled into the study. Of these, 1947 patients, 28% of whom were women
(N=545), met the criterion of aving a recent ACS event. Using logistic
regression and adjusting for age, body mass index, and history of
myocardial infarction, angioplasty, coronary artery bypass grafting,
iabetes, hypertension, current smoking or hypercholesterolemia, women had
greater odds of experiencing shortness of breath (50% vs 43% multivariate
adjusted odds atio [OR]=1.32; 95% CI, 1.08-1.62; p=0.006) palpitations
(5.5% vs 2.8%, OR=2.17; CI=1.31-3.62; p=0.003) left arm pain (34% vs
30.5%; OR=1.27; CI=1.02-1.58; p=0.03) ack ain (7.5% vs 4.8%; OR=1.56;
CI=1.03-2.37; p=0.034) neck or jaw pain (21.5% vs 13.8%; OR=1.84; CI=1.41-
2.40; p=0.001) stomach upset (28% vs 24%; OR=1.30; CI=1.03- .65; p=0.024)
and fatigue (29% vs 21.5%; OR=1.64; CI=1.29-2.07; p=0.001) than their male
counterparts. There were no gender differences in the occurrence of the
emaining symptoms such as chest pain or discomfort, shoulder pain,
indigestion, arm numbness, weakness or light-headedness. Conclusion: Women
with ACS appear to xperience a difference symptom set to that experienced
by their male counterparts. As many of these symptoms are considered
"atypical" ACS symptoms these findings may o some way towards explaining
the help-seeking delays so often reported in this group. It is essential
that educational initiatives directed towards reducing pre-hospital elays
in women with ACS, include specific information pertaining to these
gendered symptoms.

Abstract
Purpose: We hypothesized that triple-site (double-left single-right)
stimulation will result in a higher response-rate than conventional
biventricular pacing in candidates for cardiac resynchronization therapy
(CRT). Methods: This prospective, single-center, single-blinded, parallel,
controlled trial randomized a hundred consecutive patients with moderate
to severe heart failure (HF-NYHA III-IV), LV ejection fraction <=35%,
electrical and mechanical dyssynchrony and sinus rhythm in a 1:1 fashion
to triple-site or conventional CRT-D. In the triple-site group two LV
leads were implanted into two separate coronary sinus branches and
connected in parallel to the LV port of the device. Patients were followed
1 week, 1, 3 and 6 months after randomization during the blinded phase.
All potential adverse events were adjudicated by a blinded committee to
verify if the criteria for major adverse cardiovascular event
(MACE-any-cause death/heart transplant/hospitalization for HF) were
fulfilled. The primary objective evaluated response-rate, defined as the
6-month's combined endpoint of alive status, freedom from hospitalization
for HF or heart transplantation, relative>=10% increase in LV ejection
fraction, >=10% in peak oxygen consumption, and >=10% in 6-minute walking
distance. Results: Data suitable for per-protocol analysis were available
for 98 patients, 98% of those in conventional and 93.8% in triple-site
group were implanted successfully with the target device (P=NS).
Intention-to-treat analysis revealed higher response-rate in triple-site
than conventional CRT group (51.1 vs. 26.5%, P=0.014). The proportion of
triple-site patients who achieved >=10% increase in 6-minute walking
distance was higher with borderline significance (74 vs 54%, P=0.05),
proportions of subjects with >=10% increase in peak oxygen consumption (67
vs. 59% in triple-site and conventional group, respectively) and in LV
ejection fraction (77 vs. 78%, both P=NS) were similar. In the triple-site
group two patients underwent HF hospitalization, in conventional group 1
patient died from progressive HF and 7 underwent HF hospitalization.
MACE-rate was higher in conventional than triple-site group with the
borderline significance (16 vs. 4.2%, P=0.05). Conclusions: Triple-site
resynchronization results in a higher response-rate than conventional CRT.
This effect can be attributed mainly to the more pronounced functional
improvement and greater reduction of MACE events mediated by triplesite
pacing.

Abstract
Purpose: Current guidelines state that percutaneous coronary intervention
(PCI) with stents may be considered in patients with unprotected left main
stenosis (LM) as an lternative to coronary artery bypass surgery (CABG) in
the presence of anatomic conditions that are associated with a low risk of
PCI procedural complications and clinical onditions that predict an
increased risk of adverse surgical outcomes. However, there is still
considerable debate and ongoing controversy concerning the choice of
treatment or a given patient. We performed a meta-analysis of randomised,
controlled trials comparing CABG and PCI for the treatment of unprotected
LM disease. Methods: The lectronic databases MEDLINE, EMBASE and CENTRAL
(The Cochrane Controlled Clinical Trials Register) were searched for
randomised, controlled trials comparing CABG and CI or the treatment of
unprotected LM disease. Clinical events (death, non-fatal myocardial
infarction, stroke and repeat revascularization) occurring during the
first year after andomisation were analyzed. Results: The search strategy
identified 3 randomised controlled trials eligible for inclusion enrolling
a total of 1011 patients (Buszman 2008; orice 010; Boudriot/Thiele 2011).
There was no relevant heterogeneity across trials. No significant
differences between the treatment groups could be found for the risk of
death risk ratio [RR] 1.35 [95% CI 0.74 to 2.47], p=0.32) and non-fatal
myocardial infarction (RR 1.07 [95% CI 0.58 to 1.98], p=0.83). The risk of
stroke was significantly higher with ABG (RR 7.06 [95% CI 1.62 to 30.82],
p=0.009) whereas the risk of repeat revascularization was higher with PCI
(RR 0.48 [95% CI 0.32 to 0.70], p<0.001). Conclusion: In this argest
series of randomised patients with unprotected LM stenosis to date, the
risk of death and myocardial infarction during the first year of follow-up
was comparable etween CABG and PCI. However, patients undergoing CABG had
a higher risk of stroke whereas patients undergoing PCI were at a higher
risk for repeat revascularization.

Abstract
Introduction The term "acute renal disease" encompasses several conditions
of abruptly reducing renal excretory function or histopathology changes.
Acute renal disease is a major clinical issue in hospitalised patients
with persistently high morbidity and mortality rates, causing 1
substantial economic burden. It carries the risk for demand of chronic
renal replacement therapy due to irreversible loss of renal function.
While recent advances have suggested causal therapeutic approaches in
experimental models, clinical studies have not yielded convincing results.
Failure of pharmacological interventions to reverse acute human renal
disease may relate, at least in part, to delayed diagnosis, as current
clinical tests rely on functional markers of the glomerular filtration
rate that are neither sensitive nor specific for renal injury. Serum
creatinine levels are dependent on numerous non-renal factors and increase
late, often 24-48 hours after the injurious event to the kidney-a time
point considered too late for "early" intervention. 1 variety of novel
renal injury biomarkers, among them, Neutrophil Gelatinase-Associated
Lipocalin (NGAL), is emerging that may enable 1 timely diagnosis of
subclinical tubular injury, which precedes clinically manifest acute renal
disease by several days to weeks. This has been suggested to be a top
research priority by major renal societies. Methods Here we focus on
recent studies examining the biological characteristics and the diagnostic
and prognostic value of NGAL in patients at risk for acute renal disease
including advancing chronic renal disease related to autoimmune disease
(lupus nephritis, IgA nephritis, ANCA-vasculitis), specific infections
(diarrhoea-associated haemolytic uremic syndrome) and acute kidney injury
(AKI) related to sepsis/ critical illness, cardiac surgery, renal
transplantation or the use of nephrotoxic medications. Results Although
already known as a polypeptide bound with matrix metalloproteinase in
neutrophils, NGAL is now given priority as 1 promising biomarker of acute
renal disease. NGAL was (re)discovered to be expressed after renal injury.
It is rapidly induced and released from the injured renal distal nephrons
in experimental studies and various human diseases. Urinary and plasma
concentrations of NGAL increase proportionally to severity and duration of
renal injury and rapidly decrease with its attenuation. However, NGAL
release is not specific to the kidney. Measurements may be readily and
easily performed in urine and plasma using clinical laboratory platforms
or point of care devices. Currently two automated laboratory-diagnostic
systems for NGAL measurements are available. Triage NGAL (Biosite/
Inverness/Alere) is a "point-of-care" fluorescence immunoassay for the
quantitative determination of NGAL from EDTA-anticoagulated specimens of
whole blood or plasma. According to information from the manufacturer no
relevant interferences are detectable between plasma NGAL and haemoglobin
(to 5 mg/mL), lipids, rheumatoid factors, bilirubin (to 0.15 mg/mL) or
drugs like ceftriaxon, furosemid, heparin or contrast media. The
ARCHITECTUrinary-NGAL (AbbottDiagnostics) is a chemiluminescence
microparticle-immunoassay for the quantitative determination ofNGAL in
human urine. According to the manufacturers the measuring ranges of the
Triage or the ARCHITECT NGAL test are from 60 to 1300 ng/mL or from20 to
1500 ng/mL, respectively. Each specimen volume consists of a few hundred
microlitres and the measuring time of both systems is about 15min.
Summarising the relevant literature, NGAL was measured in 325 patients
with autoimmune or specific infectious diseases and in N4000 patients at
risk of AKI. Whenever renal injury occurred, as evidenced by
histopathology or subsequent increase in serum creatinine levels, NGAL
levels were higher than in patients without acute renal disease. An
increase in NGAL substantially preceded clinical diagnosis of acute renal
disease from 1 to 3 days in AKI to 12 weeks in chronically active renal
disease. Specifically, NGAL levels strongly to moderately correlated with
renal damage but not with extra-renal disease activity and a relevant
increase in NGAL levels was detected up to 3 months before worsening of
lupus nephritis diagnosed by established kidney tests [1,2]. Also, the
majority of children with diarrhoea-associated haemolytic uremic syndrome
have renal tubular epithelial cell injury as evidenced by increased
urinary NGAL concentrations compared to controls and they required renal
replacement therapy more frequently (9 out of 20 children with NGAL N200
ng/mL vs. 1 out of 14 with NGAL b200 ng/mL [3]). In a recent
meta-analysis, the sensitivity and (Figure presented) specificity of NGAL
for AKI - measured several days prior to clinical diagnosis - ranged on
average between 75% and 95% in critical illness or after exposure to
contrast media [4]. In this study, the need for the initiation of
subsequent renal replacement therapy was predicted by NGAL with a
sensitivity of 76% and a specificity of 80% (AUC-ROC 0.78, diagnostic OR
12.9); Fig. 1. In the absence of diagnostic increases in serum creatinine,
NGAL detected patients with subclinical AKI who have an increased risk of
adverse clinical outcomes [5]. The concept and definition of AKI may need
re-assessment. Discussion With the help of a predictive renal biomarker a
paradigm shift in acute renal disease diagnosis may soon develop. Early
information about acute structural kidney damage should direct the
physician's attention to the timely avoidance of a manifest and possibly
irreversible loss of renal function. NGAL-positive patients may benefit
from the earlier initiation of causal treatment for reversible factors
depending on the setting of acute renal disease. Early termination of
nephrotoxic medications and the cautious or delayed use of contrast media
would be appropriate measures. Complementation of classical renal
evaluation methods, with novel renal biomarkers may allow faster
preclinical drug development, potentially reducing drug toxicity and
nephron loss. A negative biomarker result may carry valuable information
for improved patient management and planning of hospital resources. Early
identification of acute renal disease with rapid and robust biomarkers is
a critical first step towards improvement of patient outcomes. NGAL
appears to fulfil many characteristics of an appropriate "real-time"
biomarker for detection of acute renal disease. The development of NGAL as
biomarker in clinical studies is advanced. NGAL may be used as entry
criterion for randomised controlled trials in acute renal disease.

Abstract
Background/Case Studies: Children undergoing cardiac surgery with
cardiopulmonary bypass (CPB) are susceptible to additional inflammatory
and immunogenic insults from blood transfusions. We hypothesize that
washing red blood cells (RBC) and platelets transfused to these patients
will reduce post-operative transfusion-related immune modulation and
inflammation. Study Design/Methods: Prospective, randomized, controlled
clinical trial in a University hospital pediatric cardiac intensive care
unit. Children from birth to 17 years old undergoing cardiac surgery with
CPB were randomized to an unwashed or washed RBC and platelet transfusion
protocol for their surgery and postoperative care. All blood was
leukoreduced, irradiated, and ABO identical. Plasma was obtained for
laboratory analysis: pre-op, immediately, six and 12 hours after CPB.
Primary outcome was the 12-hour post-CPB IL-6 : IL-10 ratio. Secondary
measures were post-op levels of IL-6, IL-10, C-reactive protein (CRP) and
clinical outcomes. Analysis was by intention to treat limited to patients
actually receiving transfusions. Results/ Findings: 162 subjects were
studied, 81 per group. 34 subjects (17 per group) did not receive any
blood transfusions. Storage duration of blood products was similar between
groups. Among transfused subjects, the 12-hour IL6 : IL10 ratio was
significantly lower in the washed group (3.8 v. 4.8; p = 0.04) secondary
to lower IL-6 levels (post-CPB: 65 v.100 pg/ml; p = 0.06; 6 hour: 89 v.152
pg/ml; p = 0.02; 12-hour: 84 v.122 pg/ml; p = 0.09). Day 1 post-operative
CRP was decreased in subjects receiving washed red cells (38 v. 43 mg/L; p
= 0.03). There was a numerical, but not statistically significant decrease
in total blood component transfusions (203 v. 260) and mortality (2 [3%]
v. 6 [9%] deaths) in the washed group compared to the unwashed group.
Fewer than 5% of patients received any plasma or platelet transfusions in
either arm of the study. Conclusion: Washed transfusions in cardiac
surgery reduced inflammatory biomarkers, number of transfusions, donor
exposures, and were associated with a nonsignificant trend towards reduced
mortality. These findings are the first proof that the inflammatory
response to transfusion can be mitigated by washed red cell transfusions.
In addition, these data demonstrate that routine transfusion of plasma and
platelets in neonates and children undergoing cardiac surgery with bypass
is not needed to achieve low rates of mortality. A larger study powered to
test for clinical outcomes is needed to determine whether these laboratory
findings are clinically significant.

Abstract
Background: Perioperative cerebral damage may be associated with surgery
and anesthesia. Several pharmacological and nonpharmacological therapies
for perioperative brain neuroprotection have been tested in clinical
trials with conflicting results. Objective: To assess the efficacy of
tested therapies in terms of reduction of new neurologic deficit and/or
cognitive decline and mortality rate. Methods: We searched the Cochrane
Library; Ovid MEDLINE; Ovid EMBASE (1980 to December 2010) and reference
lists of all retrieved articles. Prospective randomized controlled
clinical trials using any pharmacologic therapies for perioperative brain
neuroprotection were selected. Results: Of 5904 identified studies, 25
randomized trials met our inclusion criteria. Tested therapies were:
lidocaine, thiopental, S(+)- ketamine, propofol, nimodipine, GM1
ganglioside, lexipafant, glutamate/ aspartate and xenon remacemide,
atorvastatin, magnesium, erythropoietin, piracetam, rivastigmine,
pegorgotein and 17b-estrdiol. Global RR analysis showed no differences in
the rate of new neurologic deficit/cognitive decline between treated and
nontreated patients. Drugbased RR analysis showed that magnesium sulfate
effectively reduces postoperative neurologic deficit/cognitive decline
(RR: 0.48 95%CI 0.27- 0.85, I2=0%, P=0.01). According to the results
reported in the original studies, evidences of benefits are reported for 5
out of the 17 drugs tested: lidocaine, remacemide, erythropoietin,
piracetam and atorvastatin. Thiopental, ketamine, propofol, nimodipine,
GM1Ganglioside,lexipafant, glutamate/ aspartate enriched crystalloid
cardioplegia, xenon-based anesthesia, rivastigmine, pegorgotein and
17b-estrdiol have not shown neuroprotectant effects. Conclusions:
Magnesium sulfate can effectively reduces perioperative cerebral damage
and some studies support a neuroprtotectant effect of lidocaine,
remacemide, erythropoietin, piracetam and atorvastatin. More extensive
research and wider consensus on the methodological approach for
perioperative neurocognitive functional evaluation is needed.

Abstract
Objective: Cardioplegia distribution beyond a stenotic coronary artery may
not be adequate. This problem can be overcome by direct delivery of
cardioplegia via the vein grafts anastomosed during the operation. The aim
of this study is to investigate the results of simultaneous antegrade/vein
graft cardioplegia versus antegrade cardioplegia alone in elective CABG
patients. Material and Methods: Forty consecutive patients were randomized
into the study group to whom antegrade/vein cardioplegia and to the
control group to whom only antegrade cardioplegia was given. Both groups
were similar with respect to demographic characteristics, postoperative
ECG changes and arrhythmia in the ICU, as well as in terms of operative
and postoperative variables (p>0.05). Results: All patients had excellent
operative and postoperative periods without any complications or death.
Release of total CK, CKMB, cTnI and lactate did not differ in the
preoperative and the frst 12^th hour (p>0.05) between the
groups, whereas in the study group a peak for total CK, CKMB, cTnI and
actate, consistent with myocardial injury (p<0.05), was found in the frst
24^th hour, which returned in the 48^th hour (p>0.05).
Conclusion: The primary fnding of this study is the inferiority of
myocardial protection with simultaneous antegrade/vein graft cardioplegia
compared with antegrade cardioplegia alone. Trakya University Faculty of

Abstract
Background and objectives: Anesthesiologists are responsible for airway
management whenever they assume the anesthesia of a patient. In this
study, we compare the hemodynamic parameters of rigid laryngoscopy and
lighted stylet in patients with coronariopathies. Patients and methods:
This randomized clinical trial included 40 patients undergoing myocardial
revascularization assigned into two groups: lighted stylet and rigid
laryngoscope. Besides time of tracheal intubation in each group, heart
rate, mean arterial pressure, changes in ST segment, and central venous
pressure were evaluated during patient preparation, 1 minute and 5 minutes
after anesthetic induction, and 1 minute after tracheal intubation.
Results: Both groups were homogenous regarding demographic data. Time of
tracheal intubation in the rigid laryngoscope group (24 +/- 5 sec) was
lower than that of the lighted stylet group (28 +/- 7 sec), but without
significance. Heart rate showed a reduction in both groups during
anesthetic induction (p < 0.05), but 1 minute after tracheal intubation
the heart rate increased to levels close to baseline levels in both groups
(p > 0.05). In the rigid laryngoscope group mean arterial pressure
increased after tracheal intubation to levels close to those observed
during patient preparation (p > 0.05), while in the lighted stylet group
mean arterial pressure remained below baseline levels (p < 0.05). Central
venous pressure increased on both groups at all times (p < 0.05).
Conclusions: It was possible to observe that both techniques are safe for
tracheal intubation in patients with coronariopathies. However, lighted
stylet has fewer repercussions on mean arterial pressure. 2011 Elsevier

Abstract
Background: Reperfused myocardium post-acute myocardial infarction (AMI)
may have altered metabolism with implications for therapy response and
function recovery. We explored glucose utilization and the "reverse
mismatch" (RMM) pattern (decreased F-18-fluorodeoxyglucose (FDG) uptake
relative to perfusion) in patients who underwent mechanical reperfusion
with percutaneous coronary intervention (PCI) for AMI. Methods and
Results: Thirty-one patients with anterior wall AMI treated with acute
reperfusion, with left ventricular ejection fraction <=45%, underwent rest
rubidium-82 (Rb-82) and FDG PET 2-10 days post-AMI. Resting
echocardiograms were used to assess wall motion abnormalities. Significant
RMM occurred in 15 (48%) patients and was associated with a shorter time
to PCI of 2.9 hours (2.2, 13.3 hours) compared to patients without
significant RMM: 11.4 hours (3.9, 22.4 hours) (P = .03). Within the
peri-infarct regions, segments with significant RMM were more likely to
have wall motion abnormalities (OR = 2.3 (1.1, 4.7), P = .02) compared to
segments without significant RMM. Conclusions: RMM is a common pattern on
perfusion/FDG PET during the sub-acute phase following reperfusion of AMI
and is associated with shorter times to PCI. Within the peri-infarct
region, RMM occurs frequently and is more often associated with wall
motion abnormalities than segments without RMM. Whether this represents a
myocardial metabolic shift during the sub-acute phase of recovery warrants
further study. 2011 American Society of Nuclear Cardiology.

Abstract
Background: Previous studies have shown gender differences in left
ventricular remodeling after myocardial infarction. Results are varied,
however, and reliable, comprehensive data for changes in cardiac myocyte
shape are not available. Methods: Young adult female and male
Sprague-Dawley rats were used in this study and randomly assigned to the
myocardial infarction and sham myocardial infarction groups. Myocardial
infarction was produced by ligation of the left descending coronary
artery. Four weeks after surgery, left ventricular echocardiography and
hemodynamics were performed before isolating myocytes for size
determination. Results: In general, left ventricular functional changes
after myocardial infarction were comparable. Females developed slightly,
but significantly, more left ventricular hypertrophy than males, and this
was reflected by the relative increases in left ventricular myocyte
volume. In both males and females, however, myocyte hypertrophy was due
exclusively to lengthening of myocytes with no change in myocyte
cross-sectional area. Conclusions: This study demonstrates that
post-myocardial infarction changes in LV function and myocyte remodeling
are remarkably similar in young adult male and female rats. 2011 Elsevier

Abstract
Background The consequences of inhibition of cortisol synthesis by a
single dose of etomidate on subsequent vasopressor drug usage and the
duration of relative adrenal insufficiency (RAI) after cardiac surgery are
not known. Methods This was a prospective, randomized, double-blinded
controlled trial of 100 patients undergoing elective cardiac surgery and
receiving either etomidate or propofol at induction of anaesthesia. A
short corticotropin test was performed 12, 24, and 48 h after anaesthesia
induction. RAI was defined as a response <250 nmol litre^-1.
Results The mean (sd) norepinephrine infusion rate during the first 48
postoperative hours was 0.11 (0.01) and 0.11 (0.01) mug kg^-1
min^-1 in the etomidate and propofol groups, respectively
(P=0.89). Time to norepinephrine withdrawal was similar between the
groups. The incidence of RAI was higher in the etomidate group at 12 h
(100 vs 41, P<0.001) and 24 h (85 vs 25, P<0.001). Conclusions A single
bolus of etomidate blunts the hypothalamicpituitaryadrenal axis response
for more than 24 h in patients undergoing elective cardiac surgery, but
this was not associated with an increase in vasopressor requirements.

Abstract
Objectives: Reduction of cognitive function is a possible side effect
after the use of cardiopulmonary bypass (CPB) during cardiac surgery.
Since it has been proven that piracetam is cerebroprotective in patients
undergoing coronary bypass surgery, we investigated the effects of
piracetam on the cognitive performance of patients undergoing open heart
surgery. Methods: Patients scheduled for elective open heart surgery were
randomized to the piracetam or placebo group in a double-blind study.
Patients received 12 g of piracetam or placebo at the beginning of the
operation. Six neuropsychological subtests from the Syndrom Kurz Test and
the Alzheimer's Disease Assessment Scale were performed preoperatively and
on day 3, post-operatively. To assess the overall cognitive function and
the degree of cognitive decline across all tests after the surgery, we
combined the six test-scores by principal component analysis. Results: A
total of 88 patients with a mean age of 67 years were enrolled into the
study. The mean duration of CPB was 110 minutes. Preoperative clinical
parameters and overall cognitive functions were not significantly
different between the groups. The postoperative combined score of the
neuropsychological tests showed deterioration of cognitive function in
both groups (piracetam: preoperative 0.19 +/- 0.97 vs. postoperative -0.97
+/- 1.38, p <0.0005 and placebo: preoperative -0.14 +/- 0.98 vs.
postoperative -1.35 +/- 1.23, p <0.0005). Patients taking piracetam did
not perform better than those taking placebo, and both groups had the same
decline of overall cognitive function (p = 0.955). Conclusion: Piracetam
had no cerebroprotective effect in patients undergoing open heart surgery.
Unlike the patients who underwent coronary surgery, piracetam did not
reduce the early postoperative decline of neuropsychological abilities in
heart valve patients. 2011 The Editorial Committee of Annals of Thoracic

Abstract
This prospective, randomized, doubleblind study evaluated the effect of
ulinastatin on postoperative blood loss and transfusion requirements of
patients undergoing open-heart surgery with cardiopulmonary bypass (CPB)
and aortic cross-clamping (ACC). CPB and ACC produce variable systemic
inflammatory reactions that are associated with multiorgan dysfunction via
leucocytes, especially polymorphonuclear neutrophils (PMNs). PMNs increase
blood loss and transfusion requirements. Ulinastatin, a urinary trypsin
inhibitor, inhibits PMN activity and reduces the systemic inflammatory
response. Patients received either 5000 U/kg ulinastatin or the equivalent
volume of normal saline (control group) before ACC. Postoperative blood
loss and transfusion requirements were recorded. Duration of intubation
and length of stay in the intensive care unit (ICU) were also noted. There
were no statistically significant between-group differences in
postoperative blood loss and transfusion requirements. Ulinastatin caused
a non-significant decrease in duration of intubation. Patients who
received ulinastatin had significantly shorter ICU stays than control
patients. 2011 Field House Publishing LLP.

Abstract
This study investigated the efficacy and safety of preoperative insertion
of an intra-aortic balloon pump (IABP) in highrisk coronary
atherosclerotic disease patients undergoing off-pump coronary artery
bypass grafting (OPCAB). A total of 232 patients were recruited to the
study, of whom 107 underwent percutaneous insertion of an IABP prior to
OPCAB. The remaining 125 patients underwent OPCAB alone. Pre-, peri- and
postoperative parameters were compared between the two groups.
Preoperative insertion of an IABP was associated with a shorter stay in
intensive care, decreased incidence of postoperative dialysis and acute
heart failure, and a reduction in postoperative mortality compared with
OPCAB alone. There were no between-group differences in terms of
haematocrit level, number of distal anastomoses, volume of postoperative
drainage or incidence of reoperation for bleeding and postoperative
stroke/cerebrovascular accident. In conclusion, preoperative insertion of
an IABP improved the prognosis of high-risk CAD patients undergoing OPCAB.

Abstract
A randomised controlled trial (RCT), the PROactive study, was undertaken
to see if pioglitazone improved cardiovascular outcomes in type 2
diabetes. Initially the results were controversial and pioglitazone was
not widely recognised as a beneficial agent for cardiovascular disease. A
meta-analysis of rosiglitazone studies raising the possibility that it was
associated with cardiovascular harm received worldwide media attention and
the negative concern spread to involve pioglitazone through presumed
'class-effect'. A careful re-look at the detail of the PROactive's primary
composite endpoint, which led to the controversy over the outcome,
suggests that medical statistics may have been inadequate to reveal the
real clinical effect. A number of other studies support the interpretation
that pioglitazone significantly improves cardiovascular outcomes. While
the potential risk:benefit of pioglitazone needs to be acknowledged, it
now also needs to be recognised that pioglitazone and metformin are the
only glucose-lowering agents with RCT data demonstrating a reduction in
stroke, myocardial infarction and death in type 2 diabetes. Furthermore
there now exists a strong case that even in type 2 diabetes patients
without known cardiovascular disease, the modern paradigm for management
should involve the combination of metformin, pioglitazone and
glucagon-like peptide 1 agonists used early and aggressively to achieve a
target glycated haemoglobin A_1C <6%. The Author(s), 2011.

Abstract
Background: Treatment of the deceased heart-beating donor with low-dose
dopamine results in less dialysis requirement after kidney transplantation
and appears to improve the outcome after heart transplantation. This study
investigates the clinical course of liver allografts from multi-organ
donors that were enrolled in the randomized dopamine trial
(clinicaltrials.gov Identifier: NCT00115115). Methods: Between March 2004
and August 2007, 264 brain-dead donors were randomly assigned to receive
or to not receive low-dose dopamine. Eligibility criteria included
circulatory stability under low-dose norepinephrine. The present study is
nested in the randomized controlled trial of donor pretreatment with
dopamine. We assessed the outcomes of 197 liver transplants performed at
32 European centers. Results: Dopamine was infused at 4mug/kg/min for a
median duration of 362 minutes (IQR 182 minutes). Donors and recipients
were very similar in baseline characteristics. Thirty-four recipients
(16.8%) were transplanted with high urgency and 23 (11.7%) received a
repeat transplant. Pretransplant MELD score was not different in
recipients of a dopamine treated vs. untreated graft (18+/-8 vs. 19+/-9,
p=0.28). Mean cold ischemic time was 632+/-172 vs. 600+/-170 minutes
(p=0.20). Following transplantation, no differences occurred in
biopsyproven rejection episodes (15.3% vs. 17.2%, p=0.85), requirement of
hemofiltration (27.6% vs. 27.3%, p=0.99), and in-hospital mortality (13.3%
vs. 12.1%, p=0.85). Graft survival was 72.5% vs. 74.8% and 61.2% vs. 63.6%
at one and three years. Conclusion: Contrasting heart and kidney
transplantation, donor pretreatment with dopamine does not improve the
outcome after liver transplantation. Since liver cells specifically
express s-COMT with high activity, dopamine is rapidly degraded in-vivo,
which most likely abrogates its potential to protect the liver graft from
oxidative stress under cold storage conditions.

Abstract
Background: We studied low-dose human atrial natriuretic peptide (hANP)
infusion therapy during cardiac surgery and reported the cardiac and renal
protective effects. The efficacy of a bolus injection of hANP (the "hANP
shot") simultaneously with induction of cardioplegia has been proven in
animal experiments. In the present study the clinical effects of this
"hANP shot" were examined. Methods and Results: The subjects were 67
patients undergoing Coronary artery bypass grafting. At the time of
inducing cardioplegia, 1 group received a simultaneous bolus injection of
100 mug of hANP (hANP group) and the other group received an injection of
physiological saline (placebo group). The primary endpoints were (1)
operative mortality and complications, and (2) the creatine kinase
isoenzyme MB (CPK-MB), troponin-I, and human heart fatty acid binding
protein (H-FABP) levels. The secondary endpoints were (1) the incidence of
arrhythmia, and levels of (2) atrial and B-type natriuretic peptides, and
cyclic guanosine monophosphate (cGMP), and (3) renin, angiotensin II, and
aldosterone. Postoperative CPK-MB, troponin-I, and H-FABP levels were
significantly lower in the hANP group than in the placebo group.
Postoperative arrhythmia was significantly less frequent in the hANP group
than in the placebo group. Conclusions: It is possible to achieve
cardioprotective effects based on the safety of the "hANP shot", as well
as from biomarkers of ischemia and results related to arrhythmia. The
"hANP shot" should also be evaluated as a safer and new cardioprotective
method for cardiac surgery.

Abstract
Background: Despite mounting evidence of the benefit of intensive lowering
of low-density lipoprotein-cholesterol (LDL-C) in coronary artery disease
(CAD) patients, it has not been shown that intensive lowering of both
LDL-C and blood pressure (BP) reduces cardiovascular events in these
patients. Methods and Results: 498 patients with hypertension and
hypercholesterolemia with >=75% stenosis in at least one major coronary
artery, were recruited from 17 cardiovascular centers in eastern Japan.
Patients were randomly assigned to conventional therapy (CT) or intensive
therapy (IT). CT aimed to reduce BP to <140/90 mmHg and LDL-C to <100
mg/dl, and IT aimed for <120/80 mmHg and <80 mg/dl, respectively. The
primary endpoint was a composite of all deaths, non-fatal myocardial
infarction, unstable angina pectoris, coronary artery bypass graft
surgery, non-fatal stroke, non-fatal major vascular disease, and
peripheral artery disease. The mean follow-up period was 3.2 years. The
achieved systolic BP was 126.8 mmHg for the CT group, and 121.3 mmHg for
the IT group (P<0.001). The achieved LDL-C was 92.1 mg/dl for the CT
group, and 79.6 mg/dl for the IT group (P<0.001). We detected the primary
endpoint in 18 (7.1%) patients in the CT group, and 26 (10.7%) in the IT
group (hazard ratio 1.53, 95% confidence interval 0.84-2.80, P=0.164).
Conclusions: We could not show that intensively lowering both BP and LDL-C
reduced cardiovascular risks in Japanese CAD patients with hypertension
and hypercholesterolemia (UMIN-CTR UMIN000000571).

Abstract
Haemodynamic changes occurring during heart displacement, using moist
laparotomy pads placed behind the heart (PAD group, n = 26) or deep
pericardial traction sutures (DPS group, n = 25) to facilitate exposure of
the left anterior descending artery during off-pump coronary artery bypass
surgery, were compared. Haemodynamic variables were assessed before and 10
min after displacement of the heart. The central venous pressure, mean
pulmonary artery pressure and pulmonary capillary wedge pressure increased
in both groups. After heart displacement in the PAD group, the cardiac
index, stroke volume index, mixed venous oxygen saturation, right
ventricular ejection fraction and left ventricular stroke work index
decreased significantly, and the systemic vascular resistance and
pulmonary vascular resistance increased significantly; these parameters
remained unchanged in the DPS group. It was concluded that displacement of
the heart using moist laparotomy pads caused significant haemodynamic
derangement compared with that caused by deep pericardial traction
sutures. 2011 Field House Publishing LLP.

therapy on patient outcomes were included for review. Two reviewers
independently applied the inclusion and exclusion criteria, and any
disagreements were discussed until consensus could be reached. Searching
identified 2826 potentially relevant articles, of which 16 randomized
controlled trials with 1699 participants met inclusion criteria. Data
Extraction: Data were extracted using a predefined data extraction form by
1 reviewer and checked for accuracy by another. Methodological quality of
trials was assessed independently by 2 reviewers using the PEDro scale.
Data Synthesis: Pooled analyses with random effects model to calculate
standardized mean differences (SMDs) and 95% confidence intervals (CIs)
were used in meta-analyses. When compared with standard physical therapy,
extra physical therapy reduced length of stay (SMD=-.22; 95% CI, -.39 to
-.05) (mean difference of 1d [95% CI, 01] in acute settings and mean
difference of 4d [95% CI, 07] in rehabilitation settings) and improved
mobility (SMD=.37; 95% CI,.05.69), activity (SMD=.22; 95% CI,.07.37), and
quality of life (SMD=.48; 95% CI,.29.68). There were no significant
changes in self-care (SMD=.35; 95% CI, -.06.77). Conclusions: Extra
physical therapy decreases length of stay and significantly improves
mobility, activity, and quality of life. Future research could address the
possible benefits of providing extra services from other allied health
disciplines in addition to physical therapy. 2011 American Congress of

Abstract
Background: Despite known gender differences in recovery, few studies have
examined symptom management (SM) interventions or responses by gender
after coronary artery bypass surgery (CABS). Objective: The purpose of
this subanalysis was to describe and evaluate differences in response by
gender to an SM intervention on the presence and burden of symptoms,
physical activity, and physical functioning in elderly CABS patients
during the early discharge period (3 and 6 weeks after CABS, and 3 and 6
months after CABS). Methods: The parent study whose data were analyzed to
examine gender differences involved a two-group, randomized clinical trial
design. The 6-week early recovery SM telehealth intervention was delivered
by the Health Buddy. Measures included the Cardiac Symptom Survey, a
Modified 7-Day Activity Interview, an RT3 accelerometer, an Activity
Diary, and the Medical Outcomes Study Short Form 36. This study was not
powered for a gender x group analysis, and we used descriptive statistics,
chi² tests, t tests, and analysis of variance for statistical
analyses. Results: Subjects (n = 232) included 192 men and 40 women, with
a mean age of 71.2 SD, 7 years. The intervention group consisted of 86 men
and 23 women, and the usual care (UC) group consisted of 106 men and 17
women. Data trends suggest that the SM intervention exerted greater impact
on women than on men for symptoms such as fatigue, depression, sleep
problems, and pain. Again, men exhibited higher levels of physical
activity than did women. However, women in the SM group generally had
higher scores than did women in the UC group. Conclusion: Although the
parent study found no effect of an early recovery SM intervention, this
exploratory secondary analysis indicated that women in the intervention
group demonstrated more improvement in measures of physical activity than
did those in the UC group. Further study, using a larger sample, is
necessary to test these preliminary results. 2011 Elsevier Inc.

Abstract
Objective: This study sought to determine whether aggressive glycemic
control (90-120 mg/dL) would result in more optimal clinical outcomes and
less morbidity than moderate glycemic control (120-180 mg/dL) in diabetic
patients undergoing coronary artery bypass graft (CABG) surgery. Summary
of Background Data: Maintaining serum glucose levels between 120 and 180
mg/dL with continuous insulin infusions decreases morbidity in diabetic
patients undergoing CABG surgery. Studies in surgical patients requiring
prolonged ventilation suggest that aggressive glycemic control (<120
mg/dL) may improve survival; however, its effect in diabetic CABG patients
is unknown. Methods: Eighty-two diabetic patients undergoing CABG were
prospectively randomized to aggressive glycemic control (90-120 mg/dL) or
moderate glycemic control (120-180 mg/dL) using continuous intravenous
insulin solutions (100 units regular insulin in 100 mL: normal saline)
beginning at the induction of anesthesia and continuing for 18 hours after
CABG. Primary end points were the incidence of major adverse events (major
adverse events = 30-day mortality, myocardial infarction, neurologic
events, deep sternal infections, and atrial fibrillation), the level of
serum glucose, and the incidence of hypoglycemic events. Results: There
were no differences in the incidence of major adverse events between the
groups (17 moderate vs 15 aggressive; P = 0.91). Patients with aggressive
control had a lower mean glucose at the end of 18 hours of insulin
infusion (135 +/- 12 mg/dL moderate vs 103 +/- 17 mg/dL aggressive; P <
0.0001). Patients with aggressive control had a higher incidence of
hypoglycemic events (4 vs 30; P < 0.0001). Conclusions: In diabetic
patients undergoing CABG surgery, aggressive glycemic control increases
the incidence of hypoglycemic events and does not result in any
significant improvement in clinical outcomes that can be achieved with
moderate control. Clinical Trials.gov (ID #NCT00460499). 2011 by

Abstract
Background: No preventive pharmacologic strategies have been proven
efficacious for the prevention of postoperative effusions after cardiac
surgery. Colchicine is safe and efficacious for the prevention of
pericarditis. On this basis, we realized a substudy of the COPPS trial to
assess the efficacy and safety of colchicine for the prevention of
postoperative pericardial and pleural effusions. Methods: The COPPS is a
multicenter, double-blind, randomized trial, where 360 consecutive
patients (mean age 65.7 +/- 12.3 years, 66% men), 180 in each treatment
arm, were randomized on the third postoperative day to receive placebo or
colchicine for 1 month (1.0 mg twice daily for the first day, followed by
a maintenance dose of 0.5 mg twice daily in patients >=70 kg, and halved
doses for patients <70 kg). The incidence of postoperative effusions was
evaluated in each study group. Results: Despite similar baseline features,
colchicine significantly reduced the incidence of postoperative
pericardial (12.8% vs 22.8%, P =.019, relative risk reduction 43.9%, no.
of patients needed to treat 10) and pleural effusions (12.2% vs 25.6%, P
=.002, relative risk reduction 52.3%, no. of patients needed to treat 8).
The rate of side effects (only gastrointestinal intolerance) and drug
withdrawal was similar in the study groups with a trend toward an
increased rate of both events for colchicine. In multivariable analysis,
female gender (hazard ratio 1.76, 95% CI 1.03-3.03, P =.040) and pleura
incision (hazard ratio 2.58, 95% CI 1.53-4.53, P <.001) were risk factors
for postoperative effusions. Conclusions: Colchicine is safe and
efficacious for the primary prevention of postoperative effusions after
cardiac surgery. 2011 Mosby, Inc.

Abstract
An open-label study reported that ingestion of a fish oil concentrate
decreased the incidence of atrial fibrillation (AF) after coronary artery
bypass grafting (CABG) surgery. However, a general cardiac surgery
population involves valve and CABG surgeries. We undertook a
double-blinded randomized controlled trial to examine the effectiveness of
fish oil supplementation on the incidence of postsurgical AF after CABG
and valve procedures. The primary end point was incidence of AF in the
first 6 days after surgery. Two hundred patients were randomized to
receive fish oil (providing 4.6 g/day of long-chain -3 fatty acids) or a
control oil starting 3 weeks before surgery; 194 subjects completed the
study, with 47 of 97 subjects in the control group and 36 of 97 subjects
in the fish oil group developing AF (odds ratio 0.63, 95% confidence
interval [CI] 0.35 to 1.11). There was a nonstatistically significant
delay in time to onset of AF in the fish oil group (hazard ratio 0.66, 95%
CI 0.43 to 1.01). There was a significant decrease in mean length of stay
in the intensive care unit in the fish oil group (ratio of means 0.71, 95%
CI 0.56 to 0.90). In conclusion, in a mixed cardiac surgery population,
supplementation with dietary fish oil did not result in a significant
decrease in the incidence of postsurgical AF. However, there was a
significant decrease in time spent in the intensive care unit. 2011

Abstract
Aims Long-term randomized comparisons of percutaneous coronary
intervention (PCI) to coronary artery bypass grafting (CABG) in left main
coronary (LM) disease and/or three-vessel disease (3VD) patients have been
limited. This analysis compares 3-year outcomes in LM and/or 3VD patients
treated with CABG or PCI with TAXUS Express stents. Methods and
resultsSYNTAX is an 85-centre randomized clinical trial (n 1800).
Prospectively screened, consecutive LM and/or 3VD patients were randomized
if amenable to equivalent revascularization using either technique; if
not, they were entered into a registry. Patients in the randomized cohort
will continue to be followed for 5 years. At 3 years, major adverse
cardiac and cerebrovascular events [MACCE: death, stroke, myocardial
infarction (MI), and repeat revascularization; CABG 20.2 vs. PCI 28.0, P<
0.001], repeat revascularization (10.7 vs. 19.7, P< 0.001), and MI (3.6
vs. 7.1, P 0.002) were elevated in the PCI arm. Rates of the composite
safety endpoint (death/stroke/MI 12.0 vs. 14.1, P 0.21) and stroke alone
(3.4 vs. 2.0, P 0.07) were not significantly different between treatment
groups. Major adverse cardiac and cerebrovascular event rates were not
significantly different between arms in the LM subgroup (22.3 vs. 26.8, P
0.20) but were higher with PCI in the 3VD subgroup (18.8 vs. 28.8, P<
0.001). Conclusion sAt 3 years, MACCE was significantly higher in
PCI-compared with CABG-treated patients. In patients with less complex
disease (low SYNTAX scores for 3VD or low/intermediate terciles for LM
patients), PCI is an acceptable revascularization, although longer
follow-up is needed to evaluate these two revascularization strategies.

Abstract
Children and adolescents on oral anticoagulation therapy (OAT) present
special challenges in terms of rapid fluctuations in International
Normalised Ratio (INR) values, interruption in daily life due to frequent
hospital/doctor visits, and difficulties and pain in the performance of
venepuncture. Optimised management of OAT improves the quality of
treatment, potentially accomplished by new methods such as patient
self-testing (PST) and patient self-management (PSM). A review was
performed, identifying 11 trials with children and adolescents. All
studies had different methodological problems, predominantly by being
non-randomised trials. A total of 284 patients were included with a mean
follow-up of 22 months, finding a time within therapeutic INR target range
between 63% and 84%. The coagulometers used for estimating the INR values
were found to have sufficient precision and accuracy for clinical use, but
external quality control is probably advisable. It can be concluded that
PST and PSM are at least as good treatment options as conventional
management in highly selected children. Larger studies, preferably
randomised, controlled trials using clinical endpoints, are obviously
needed in order to elucidate whether these new regimens of treatment are
superior to conventional management of oral anticoagulation therapy.

Abstract
A systematic review was conducted of all published cases of endovascular
repair of retrograde Stanford type A dissection or intramural hematoma to
determine mortality of this less invasive approach to treatment. Using the
PRISMA guidelines, databases were searched for any of the terms
'dissect$', 'IMH', ('aortic ADJ wall'), 'intramur$', 'intra-mur$' in
combination with any of 'stent$', 'perc$', 'endo$', 'TEVAR' in combination
with any of ('type ADJ A'), 'ascend$' and 'retro$.' The search retrieved
3131 titles, 280 abstracts, and 108 papers. Of 23 relevant papers
selected, mortality data could be extracted from 11 studies, representing
60 patients. Overall in-hospital mortality was 1.8% (95% CI 1.2% to 2.4%).
Additional all-cause mortality during follow-up was 5.4% (95% CI 3.5% to
7.2%). The placement of an endoluminal device in the descending thoracic
aorta to treat a DeBakey IIId/retrograde type A aortic dissection or
intramural hematoma may be a safer procedure in the short to medium term
than open surgical replacement of the ascending aorta (with or without the
arch). Open surgical repair in these patients may therefore be
unjustified. 2011 by the International Society of Endovascular

Abstract
Statement of the Problem: Several observational case series studies
indicate that maxillomandibular advancement surgery (MMA) may be a
clinically effective alternative therapy for patients with obstructive
sleep apnea (OSA) who are unable to adhere to CPAP therapy. Surgical
treatment involves inherent risks and it is essential to define the type,
severity and incidence of these potential adverse outcomes to determine
the risk benefit ratio of MMA for the treatment of OSA. To date the
adverse outcomes of MMA have not been systematically analyzed or reported.
The purpose of this study is to determine the type, severity and incidence
of surgical and anesthetic adverse outcomes following MMA for treatment of
OSA. Materials and Methods: This is a retrospective cohort study
consisting of 76 patients who underwent MMA for treatment of OSA at
Vanderbilt Medical Center between 1997 and 2007. A comprehensive
systematic review of the surgical, anesthesia/recovery room and progress
notes were completed for each patient to identify all perioperative
complications, as well as post-operative wound healing problems.
Additionally, polysomnography reports were analyzed to determine the
effectiveness of MMA, as measured by changes in the apnea-hypopnea index
(AHI) and low oxygen saturation after MMA. Methods of Data Analysis:
Descriptive statistical analysis was performed for all continuous
variables and reported as mean +/- SD. The number and proportion of
patients with each observed adverse outcome were tabulated. Two-tailed
paired t tests were used to assess changes in the apnea-hypopnea index
(AHI) and low O2 saturations following MMA. For all analyses, a p-value of
<0.05 was considered statistically significant. Results of Investigation:
The majority of patients were obese (BMI +/- 31.2 +/- 6.9) middle-aged
(45.4 +/- 9.9 years) males (80%) with severe OSA (AHI +/- 54.3 +/- 27.0;
low % SaO2 +/- 77.8 +/- 13.0). Pre-operatively, the group had multiple
co-morbid medical conditions including: hypertension (36%), cardiovascular
disease (14%), history of non-fatal cardiovascular events (9%) and
depression (21%). Standardized osteotomy and stabilization techniques were
used to accomplish MMA. Modified hypotensive anesthetic techniques were
used for the majority of patients (93%). There were no observed deaths or
cardiac events. Intra-operatively the airway was managed by intubation in
the vast majority of patients (96%) with tracheotomy performed in only one
patient. 3% of patients required re-intubation for perioperative control
of the airway. The estimated average blood loss was 390.6 +/- 227.1 ml and
5% of patients received a blood transfusion. No patients experienced
complications requiring return to the operating room. Following surgery,
patients required 2.6 +/- 1.7 days of hospitalization. Wound infections
were uncommon (8%) and were effectively treated by local measures and oral
antibiotics, with no patients requiring intravenous antibiotics or
hospitalization. Surgical treatment by MMA resulted in a significant
reduction in AHI in (54.3 +/- 27.0 to 13.3 +/- 11.6, P <.001) and
improvement in minimum oxygen saturation (77.8% to 83.8%, P <.001).
Conclusion: The results of this study indicate that MMA has a very
favorable risk-benefit ratio, as it may provide safe and effective
treatment for patients with moderate to severe OSA who are unable to
adhere to CPAP therapy.
