Preconditioning represents the most effective form of cardioprotection that can be induced to attenuate the injury accompanying a longer lasting ischemia (=index ischemia) of sufficient duration and severity to cause myocardial necrosis. Precondition

Background Postconditioning (postcon) reduces infarct size, myocardial superoxide (•O2) generation, and neutrophil (PMN) accumulation. It is unknown whether inhibition of PMNs influence cardioprotection by postcon. The present study tested the foll

Background Off-pump, multivessel, endoscopic coronary artery bypass requires cardiac displacement within an intact chest. The current study evaluated right ventricular performance and systemic hemodynamics while exposing the posterior surface of the

After many years of debate during which the preponderance of opinion was skeptical about the experimental and clinical existence of reperfusion injury (with attitudes ranging between polite condescendence and overt denial), it can be said that the co

Background : Protease activated receptor 2 (PAR2) is a member of the seven transmembrane G-protein coupled receptor (GPCR) family. Activation of PAR2 is cardioprotective in ex vivo and in vivo myocardial ischemia reperfusion model, potentially by cog

Acute Epicardial Pacing in Immature Piglet Hearts. Introduction: Single-site ventricular pacing results in dyssynchronous ventricular activation and may contribute to ventricular dysfunction. We evaluated epicardial biventricular (BiV) pacing as a me

Background—Various studies have reported that the administration of adenosine (ADO) in cardioplegia reduces myocardial ischemic injury, but this timing may not utilize ADO’s potential against myocardial reperfusion injury. This study tested the h

Positron emission tomography allows noninvasive assessment of myocardial blood flow and metabolism, and may aid in defining the extent and severity of an ischemic injury. This hypothesis was tested by studying, in chronically instrumented dogs, regio

Free fatty acids are the major energy source for cardiac muscle. Oxidation of fatty acid decreases or even ceases during ischemia. Its recovery after transient ischemia remains largely unexplored. Using intracoronary carbon-11 palmitic acid as a trac
