Changes

At autopsy the heart weighed 500 grams. There was massive acute myocardial infarction (about 2 days old) involving the posterior left ventricle, interventricular septum, and right ventricle from apex to base. The infarct was transmural, and there was a small rupture in the soft infarcted area at the apex. There were 1200 mL of blood within the right pleural cavity, probably secondary to this rupture. The coronary arteries showed moderate to severe atherosclerosis throughout the coronary tree.
