BACKGROUND: Class I evidence supporting a threshold for transfusion in the cardiac surgical setting is scarce. We randomly allocated patients to a transfusion hematocrit trigger of 24% versus 28% to compare morbidity, mortality, and resource use. METHODS: From March 2007 to August 2014, two centers randomly assigned 722 adults undergoing coronary artery bypass graft surgery or valve procedures to a 24% hematocrit trigger (n = 363, low group) or 28% trigger (n = 354, high group)...

OBJECTIVE: Systemic inflammation is a recognised contributory factor in the pathogenesis of de novo post-operative atrial fibrillation after cardiac surgery. This study aims to determine whether serum soluble vascular endothelial cell adhesion molecule (sVCAM-1) may predict the onset of POAF in patients under going coronary artery bypass grafting. METHODS: 34 patients undergoing non-emergent, on-pump CABG were prospectively recruited. Plasma was obtained at 24 h pre-operatively and at 48 and 96 h post-operatively...

Clinical trials using stem cell therapy for heart diseases have not reproduced the initial positive results obtained with animal models. This might be explained by a decreased regenerative capacity of stem cells collected from the patients. This work aimed at the simultaneous investigation of endothelial stem/progenitor cells (EPCs), mesenchymal stem/progenitor cells (MSCs), and hematopoietic stem/progenitor cells (HSCs) in sternal bone marrow samples of patients with ischemic or valvular heart disease, using flow cytometry and colony assays...

Coronary artery disease (CAD) is the most common cardiovascular disease while atrial fibrillation (AF) is the most common cardiac arrhythmia. Both diseases share associated risk factors - hypertension, diabetes mellitus, sleep apnea, obesity and smoking. Moreover, inflammation plays a causative role in both diseases. The prevalence of CAD in patients with AF is from 17% to 46.5% while the prevalence of AF among patients with CAD is low and it is estimated from 0.2% to 5%. AF is a well-established factor of poor short- and long-term prognosis in patients with acute myocardial infarction (AMI) and is associated with a marked increase in overall mortality...

Major randomized clinical trials over the last decade support the role of optimal medical therapy for the initial management approach for patients with stable coronary artery disease (CAD), whereas percutaneous coronary intervention (PCI) ought to be reserved for patients with persistent symptoms despite optimal medical therapy. Likewise, several studies have continued to demonstrate the superiority of coronary artery bypass grafting surgery over PCI in many patients with extensive multivessel CAD, especially those with diabetes...

OBJECTIVE: We sought to assess hospital cost variation for elective inpatient surgical procedures within small geographic areas. SUMMARY BACKGROUND DATA: Previous studies have documented cost variation for inpatient surgical procedures on a national basis, suggesting opportunities for savings. Cost variation within small geographic areas is more relevant to policymakers, providers, and patients, but it has not been studied. METHODS: Using Medicare payment data, we identified elderly patients undergoing 1 of 7 elective inpatient surgical procedures during 2010-2012...

OBJECTIVES: Adverse neurologic outcome can be a debilitating complication after cardiac surgery. The aim of this study was to investigate the potential neuroprotective action of erythromycin, a well known antibiotic agent, regarding postoperative cognitive decline in patients undergoing cardiac surgery. METHODS: Forty patients scheduled for elective coronary artery bypass grafting surgery were prospectively randomly assigned in 2 groups: the erythromycin group (n = 19) who received erythromycin at a dose of 25 mg/kg before and after surgery and the control group (n = 21) who did not receive it...

INTRODUCTION: Historically, perioperative hemoglobin monitoring has relied on calculated saturation, using blood gas devices that measure plasma hematocrit (Hct). Co-oximetry, which measures total hemoglobin (tHb), yields a more comprehensive assessment of hemodilution. The purpose of this study was to examine the association of tHb measurement by co-oximetry and Hct, using conductivity with red blood cell (RBC) transfusion, length of stay (LOS) and inpatient costs in patients having major cardiac surgery...

Background Coronary-artery bypass grafting (CABG) surgery may be performed either with cardiopulmonary bypass (on pump) or without cardiopulmonary bypass (off pump). We report the 5-year clinical outcomes in patients who had been included in the Veterans Affairs trial of on-pump versus off-pump CABG. Methods From February 2002 through June 2007, we randomly assigned 2203 patients at 18 medical centers to undergo either on-pump or off-pump CABG, with 1-year assessments completed by May 2008. The two primary 5-year outcomes were death from any cause and a composite outcome of major adverse cardiovascular events, defined as death from any cause, repeat revascularization (CABG or percutaneous coronary intervention), or nonfatal myocardial infarction...

OBJECTIVE: The inflammatory response elicited by robotically enhanced coronary artery bypass grafting (r-CABG) has not been well described. When r-CABG is performed as part of hybrid coronary revascularization, the inflammatory milieu and the timing of percutaneous coronary intervention may affect the stent patency negatively in the short and long term. The goal of this study was to describe the extent and time course of cytokine release after r-CABG compared with conventional CABG (c-CABG) and to elucidate the optimal timing for r-CABG in the setting of hybrid coronary revascularization for a future study...

BACKGROUND: This study aimed to assess the deformation of the mitral valve complex during the displacement of the beating heart by using three-dimensional echocardiography in a porcine off-pump coronary artery bypass grafting (OPCAB) model. METHODS: In nine healthy swine, we positioned the beating heart as an OPCAB model, i.e. control, left anterior descending artery (LAD), right coronary artery (RCA), and left circumflex artery (LCX) positions. In each position, three-dimensional echocardiography was performed to assess the mitral valve complex with hemodynamic parameters...

OBJECTIVE: Lipid lowering therapy is widely used for the prevention of cardiovascular complications after acute myocardial infarction (AMI). However, some studies show that this benefit is uncertain in patients with renal dysfunction, and the role of statins is based on the severity of renal dysfunction. In this study, we investigated the impact of statin therapy on major adverse cardiac events (MACEs) and all-cause mortality in patients with advanced renal dysfunction undergoing percutaneous coronary intervention (PCI) after AMI...

PURPOSE OF REVIEW: The coronary artery bypass graft (CABG) operation is one of the few remaining operations/interventions on diseased arteries that are not routinely verified during or immediately after the procedure. This review answers the 'how', 'when' and 'why' of intraoperative CABG assessment. RECENT FINDINGS: More recent than new literature on this topic, is the increased interest in quality assurance of CABG. This is most likely due to reports in the last 5 years suggesting CABG superiority to percutaneous coronary intervention (PCI) for improved mid-term and long-term outcomes; for example, for patients with diabetes mellitus (Freedom Trial by Farkouh in 2012), and for patients with SYNTAX score ≥ 33 (SYNTAX Trial by Mohr in 2013)...
