title: A comparison between propranolol and hypothermia in preventing ischemic contracture of the left ventricle (stone heart).
abstract: Ischemic contracture of the left ventricle ("stone heart") was studied utilizing a previously described stone heart model. Our studies suggest that beta-adrenergic blockade is not quantitatively as important as hypothermia in protecting ischemic myocardium. On the basis of reduced fibrillatory activity and a slight protective effect shown by electron microscopy, it would appear that combining propranolol with hypothermia may be superior to either used singly.
