Abstract
An autopsy protocol devised specifically for the study of hearts from patients succumbing to ischemic heart disease is presented. This protocol was employed in a consecutive series of 63 patients dying of ischemic heart disease. It comprises a meticulous histological examination of the coronary arteries, including quantitation of luminal narrowing. The ventricular myocardium is sliced transversely, and the Nitro-BT test is applied to identify and delineate acute myocardial infarction, the extent of which is quantitated by point-counting. The sinoatrial and the atrioventricular nodes are examined histologically for histopathological changes responsible for conducting disturbances.
