Acute coronary occlusion following blunt injury to the chest in the absence of coronary atherosclerosis.
A 35-year-old man suffered transmural diaphragmatic wall infarction immediately after receiving a nonpenetrating trauma to his chest. During subsequent months crippling angina pectoris developed and coronary arteriography was performed. A complete obstruction of the left circumflex coronary artery was demonstrated 2 cm. distal to its origin. In contrast to most cases previously published, in this case no signs of atherosclerosis were observed in the other coronary arteries. It must be assumed, therefore, that blunt trauma can induce complete coronary occlusion with infarction, even in subjects with normal coronary arteries.
