Abstract

It is well known that the increase of necrotic core in previous atherosclerotic coronary artery disease is one of the conditions of vulnerable plaque. However, it is not known how fast necrotic core could decrease in a vulnerable plaque. We had 2 patients who had suffered from acute myocardial infarction and had large amount of necrotic core in their culprit lesions at baseline, which decreased markedly within 7 days. Also, they were clinically stable and asymptomatic over 1 year follow-up. It is first report to show mar-kedly decrease of necrotic core amount within only 7 days in culprit lesions of 2 cases of acute myocardial infarction with angiographically minimal lesions.
