A Case Report of Acute Myocardial Infarction in a Patient with Servere Aortic Stenosis and Normal Coronary Arteries

ABSTRACT

The incidence of angina pectoris(AP) in patients with severe aortic stenosis(AS) and normal coronary arteries has been reported to be 30 to 40%. The pathophysiologic mechanism suggests marked decrease in coronary rederve with left ventricular hypertrophy secondary AS and mismatched oxygen demand-supply by valvular pressure gradient, but only 1 case of acute myocardial infarction(AMI) was reported in severe AS and normal coronary arteries as far as we are concerned. We report a case of AMI occuring in a patient with severe AS and left ventricular hypertrophy. A coronary angiogram excluded coronary obstruction and spasm as the cause of AMI in this patient.
