	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.		At autopsy the heart weighed 500 grams.

			This 83-year-old male developed chest pain. He had been awakened the previous night with dull chest pain which was retrosternal and radiated through to his back. The pain was associated with sweating, nausea, and vomiting and could not be relieved by antacids. He refused to go to the doctor but the next morning he developed severe epigastric pain and had several episodes of tachycardia (150-160 beats per minute) and later cardiac standstill. He had a history of hypertension and diabetes.

 * <spoiler text="What is the source for the fibroblasts and endothelial cells that are present in organizing thrombi?">Organization of a thrombus involves a process similar to the normal healing response. First there is inflammation with macrophages that phagocytose the thrombotic material.
