	This 78-year-old male experienced a posterior myocardial infarction six years prior to this admission. Recently, he had begun to experience occasional angina. Four days prior to death, he experienced anterior chest pain and discomfort which he regarded as not too distressing. However, EKGs showed a classic acute anterior myocardial infarction in addition to the healed posterior infarct. His bloodwork also showed an elevated troponin. The patient progressively deteriorated with signs of left ventricular failure and died with arrhythmias and pulmonary edema.

The patient progressively deteriorated with signs of left ventricular failure and died with arrhythmias and pulmonary edema.

			At autopsy his heart showed a healed posterior infarct. The right coronary artery was completely occluded but partially recanalized. The left main coronary artery had severe atherosclerotic stenosis and a thrombus filling the lumen. The entire anterolateral aspect of the left ventricle was soft with variegated areas appearing hyperemic or pale. There was extensive mural thrombosis and reactive pericarditis.

There is a layer of surviving myocardial tissue (1) along the epicardium and then a blue line (2) which represents the accumulation of inflammatory cells at the border of the infarct. There is thrombotic material (3) adherent to the endocardial surface.		File:IPLab3AcuteMyocardialInfarction1a.JPG\|This is a low-power photomicrograph of infarcted heart.
