Myocardial ischemia/reperfusion injury affects not only the cardiomyocyte compartment but also all other cellular compartments, and the coronary circulation has a central role in it. Acute myocardial infarction most often arises from atherosclerotic plaque rupture/erosion with superimposed thrombosis (type 1 myocardial infarction). However, in the absence of coronary atherosclerosis, coronary v...

HBOC-201 (Biopure; Cambridge, MA) is a glutaraldehyde-polymerized bovine hemoglobin (Hb) solution that is stroma free, has lower viscosity than blood, and promotes O(2) unloading. We investigated the effects of HBOC-201 in a canine model of myocardial ischemia-reperfusion injury. Dogs were anesthetized and subjected to 90 min of regional myocardial ischemia and 270 min of reperfusion. HBOC-201 ...

BACKGROUND The heart is a tumor necrosis factor-alpha (TNF-alpha)-producing organ. Recent basic experimental and clinical evidence suggests that TNF-alpha is an important mediator of myocardial injury during acute myocardial infarction, chronic heart failure, cardiac allograft rejection, and cardiopulmonary bypass operations. Although it is known that the myocardium itself is capable of produci...

Myocardial protection from ischemic and reperfusion injury is an important task of modern experimental clinical medicine. This type damage a key link in the pathogenesis coronary heart disease and, above all, acute myocardial infarction – socio-economically significant that one main causes disability mortality adult population Republic Belarus. The aim study was to elucidate cardioprotective ef...

1. To recognise that acute myocardial ischaemia/reperfusion injury is a neglected therapeutic target for cardioprotection that is responsible for the ongoing morbidity and mortality of patients with ischaemic heart disease. 2. To be aware that cardiac bypass surgery and STEMI are the major clinical settings in which the heart is subjected to acute ischaemia/reperfusion injury. 3. To be familiar...

OBJECTIVE Peripheral vascular surgery involving limb ischemia/reperfusion is associated with tumor necrosis factor-alpha production and an increased risk of cardiac complications. The objective of this study was to investigate the role of tumor necrosis factor-alpha in myocardial apoptosis and dysfunction following hindlimb ischemia/reperfusion. DESIGN Randomized perspective animal study. S...

Background—N-Ethoxy-N-ethyl-dithiocarbamato-nitrido-Tc (Tc-N-NOET) is a new neutral lipophilic Tc-labeled myocardial perfusion agent with a high first-pass extraction fraction and delayed redistribution kinetics after transient ischemia comparable to what is observed with Tl. It is unknown whether the uptake of this tracer reflects myocardial viability or just reperfusion flow in the setting of...

Peroxisome proliferator-activated receptor α (PPARα) is highly expressed in heart, but its metabolic regulation effect in rats with myocardial ischemia/reperfusion injury is still a controversy. In this study, the cardioprotective effect of PPARα activation in rats with myocardial ischemia/reperfusion injury and its relevant mechanism was investigated. Adult male Wistar rats were pretreated wit...
