Impending myocardial infarction in a patient with marked left ventricular hypertrophy and normal coronary arteriogram--a case report.

A middle-aged woman with long-term uncontrolled arterial hypertension developed a clinical picture of impending myocardial infarction. A normal coronary arteriogram was obtained. However, left heart catheterization showed a marked increase in left ventricular end-diastolic pressure, while left angiocardiography revealed marked left ventricular hypertrophy. She was successfully treated with a beta-blocking and calcium-antagonist agent. The present case shows that an impending myocardial infarction may occur in patients having normal coronary arteriogram but with left ventricular hypertrophy secondary to arterial hypertension.
