A lumped-parameter model of the canine closed-loop circulation has been developed. The model consists of the following components: the right heart (atrium and ventricle), pulmonary circulation (pulmonary arteries, capillaries, and veins), left heart

Postconditioning (postcon) reduces infarct size, myocardial superoxide ((•)O(2)) generation, and neutrophil (PMN) accumulation. It is unknown whether inhibition of PMNs influence cardioprotection by postcon. The present study tested the following h

Aortic cross-clamping is contraindicated in patients with severe atherosclerosis of the ascending aorta, and administration of chemical cardioplegia may be cumbersome in these patients. In this study, we demonstrate an alternative method of achieving

Myocardial apoptosis is primarily triggered during reperfusion (R). The aim of this study was to test the hypothesis that R-induced apoptosis develops progressively during the late phase of R, and that R-induced apoptosis is associated with changes i

The goals of myocardial protection during cardiac surgery are not only to facilitate the operation by providing a quiet bloodless field, thereby facilitating the precision of the operation, but also to avoid iatrogenic injury induced by cardiopulmona

Hemodynamic stability during cardiac manipulation for complex, multivessel off-pump coronary artery bypass grafting (OPCAB) remains problematic.A servo-controlled pump has been utilized to deliver warm whole blood to coronary grafts prior to construc

Peroxynitrite (ONOO(-)) is widely recognized as a mediator of NO. toxicity, but recent studies have indicated that this compound may also have physiologic activity and induces vascular relaxation as well as inhibition of platelet aggregation and neut

Neutrophils are pivotal in the pathogenesis of reperfusion injury leading to myocardial infarction. Firm adhesion of PMN to endothelium may be initi- ated by the interaction between constitutively expressed intercellular adhesion molecule-i (ICAM-i)

This study tests the hypothesis that adenosine A2 receptor activation reduces reperfusion injury by inhibiting neutrophils in a canine model of ischemia and reperfusion. In 16 anesthetized, open-chest dogs, the left anterior descending coronary arter
