Myocardial Infarction
This was a 57-year-old male whose hospital course following abdominal surgery was characterized by progressive deterioration and hypotension. Four days post-operatively, the patient sustained an anterior myocardial infarction and died the next day.
== Autopsy Findings ==The At autopsy the patient's heart weighed 410 grams. Examination of the coronary arteries revealed marked atherosclerotic narrowing of all three vessels with focal occlusion by a thrombus of the left anterior descending artery. Fresh necrosis of the anterior wall of the left ventricle and anterior portion of the septum was present, extending from the endocardium to the inner half of the ventricular wall.

File:IPLab1MyocardialInfarction1.jpg|In this gross photograph of the heart from this case, note the area of fresh myocardial infarction (arrows) in the anterior portion of the left ventricle and extending into the anterior portion of the interventricular septum. Note that the walls of the left and right ventricle are slightly thicker than normal.
File:IPLab1MyocardialInfarction2.jpg|This is a low-power photomicrograph of the left ventricular free wall extending from the epicardium (1) to the endocardium (2). The area of infarction is the darker red (hypereosinophilic area) along the subendocardium (3).
File:IPLab1MyocardialInfarction7.jpg|This high-power photomicrograph contains normal myocytes (1), vacuolated myocytes (2), and infarcted myocytes (3).
