title: Acute myocardial infarction with simultaneous occlusions of two major coronary arteries in a young man.
abstract: Simultaneous formation of the thrombi in two different coronary arteries is a very rare event. We present a 34-year-old man with acute myocardial infarction due to simultaneous occlusion of the two major coronary arteries. His only risk factor was smoking 40 cigarettes daily. Emergency arteriography revealed a total occlusion of the proximal left anterior descending artery (LAD) and the left circumflex coronary artery (LCx). We performed primary angioplasty to the LAD and instituted thrombolytic therapy to the LCx. During intra-aortic balloon pumping and medical treatment, the patient had no symptoms of angina. He underwent a second catheterization 4 weeks after primary angioplasty. After intravenous ergonovine provocation, coronary arteriography revealed diffuse vasospasm of the LAD and the LCx. These data suggest that habitual heavy smoking and coronary spasm may have been causatory factors for myocardial infarction in this case.
