Decision to select unprotected left main (ULM) stenting versus coronary artery bypass grafting surgery (CABG) depends on a multiplicity of factors, one of the most critical of which is myocardial viability. Delayed enhancement cardiac magnetic resonance (CMR) imaging has emerged as a useful means of comprehensively evaluating viable myocardium in ...

BACKGROUND: A debate exists whether obesity is a risk factor for operative mortality after coronary artery bypass graft surgery (CABG). The contradictory findings in the literature may largely be attributable to the variety of methodological approaches used to model the association between body mass index (BMI) and post-CABG outcomes. This ...

Increasing evidence suggests that tight glycemic control improves clinical outcomes after coronary artery bypass grafting (CABG). However, the risk for hypoglycemia with insulin often results in less aggressive glycemic control. Glucagon-like peptide-1 (GLP-1) is a naturally occurring peptide whose insulinotropic effects are predicated on the glucose concentration, minimizing the risk ...

Originally, tissue stabilizer has been developed by Medtronic, Inc. It is used to prevent a certain part of myocardium from moving. For example, such an approach is utilized during Coronary Artery Bypass Grafting (CABG). Moreover, medical procedures during such operations involve blood arrest, thus, potentially may involve ischemia of myocardium. ...
Kalisnik Jurij M - - 2007
BACKGROUND: Altered autonomic regulation after cardiac operations precipitates cardiac arrhythmias, affects repolarization, and increases the risk of sudden cardiac death. We sought to clarify how the 2 different techniques of coronary artery bypass grafting (CABG), namely conventional CABG using cardiopulmonary bypass (on-pump) and beating-heart CABG without cardiopulmonary bypass (off-pump), affect ...

High shear forces can induce structural changes in the shape of the von Willebrand factor (VWF) molecule, making it more sensitive for ADAMTS-13, a specific VWF protease. This leads to proteolysis of the highest-molecular-weight multimers, which are the most effective in platelet-mediated hemostasis under conditions of high shear stress. The ...
