title: Arteriosclerotic coronary arterial aneurysms in a 49-year-old man with crescendo angina: family history, natural course and prevalence.
abstract: In a 49-year-old man with crescendo angina, elevated serum cholesterol level and an old posterior myocardial infarction, selective coronary arteriography showed multiple arteriosclerotic aneurysms of the right coronary artery associated with extensive and severe arteriosclerotic disease of the left coronary artery. The patient's mother and brother have both died of a myocardial infarction. Another brother suffers from angina and has documented arteriosclerotic coronary artery disease. Two sisters suffer from angina as well. The possibility of embolization of distal vessels from a friable clot of the aneurysms as a cause of the patient's infarction is discussed. To the best of our knowledge, this is the tenth patient with nonfistulous arteriosclerotic coronary artery aneurysm diagnosed and documented angiographically ante mortem. Including the present case and reviewing the literature, the prevalence of this condition among nonfistulous coronary aneurysms diagnosed ante mortem is 35 per cent and henceforth cannot be regarded as an incidental autopsy finding in cardiac asymptomatic patients.
