Cardiac function in the chronically volume-overloaded canine heart.

abstract：:Reperfusion following various intervals of coronary occlusion has produced conflicting results: increase in infarct size, especially with hemorrhage into the tissue, was reported as well as salvage of ischemic myocardium. To examine the problem and for the validation of our own method for infarct size measurement, whi...
