Regional Myocardial Blood Flow
Do oxygen-derived free radicals, generated at the time of reperfusion, lethally injure viable, previously ischemic myocardium, damage vascular endothelium, and impair recovery of postischemic contractile function? To address these issues, 23 anesthetized open-chest dogs underwent 2 hours of left anterior descending coronary artery occlusion followed by 4 hours of reperfusion. Immediately prior ...
متن کاملRegional Myocardial Blood Flow
nary artery disease has provided an intense stimulus for expansion of our present knowledge of the coronary circulation. In the experimental animal laboratory, the electromagnetic flowmeter has proved to be an excellent tool by which one can study dynamic aspects of the coronary circulation. A flowmeter is clearly unsuitable for human investigation; therefore, the search for a simple method of ...

متن کاملRegional myocardial blood flow and myocardial function during acute right ventricular pressure overload in calves.
Hemodynamicg, myocardial function, and regional myocardial blood flow (MBF) were measured during acute right ventricular (RV) pressure overload created by inflation of a previously implanted cuff to constrict the pulmonary artery trunk (PAC) in seven closed-chest, anesthetized calves during normoxia (Pad: 90-110 mm Hg) and hypoxia (PaOj ~ 40 mm Hg). MBF was determined by the microsphere method....
