Abstract

The authors have observed directly the effects of vasoactive drugs on the epimyocardial small arterioles in the beating left ventricle and the difference in effective sites of the different vasoactive agents on coronary vessels in a beating heart in situ. They have found direct evidence that coronary small arterioles are scarcely dilated by intravenous injection of nitroglycerin, markedly dilated by dipyridamole, and slightly constricted by propranolol, in the beating canine left ventricle.
