ENGLISH ABSTRACT: A 60-year-old woman with mild hypertension and presumed ischaemic heart disease was followed up over a very long period on account of angina pectoris. Acute myocardial infarction (MI) was suspected on the basis of the history, ECG findings and serum enzyme values, but disproved by radio-isotope investigation. Echocardiography demonstrated features of hypertrophic obstructive cardiomyopathy (HOCM), a diagnosis supported by cardiac catheterization and endomyocardial biopsy (EMB). Histological features of HOCM were absent from left ventricular EMB specimens despite a significant intraventricular gradient, but the right ventricular EMB demonstrated extensive changes of HOCM despite a small intraventricular gradient. Cardiac catheterization excluded previous MI and coronary artery disease. A further interesting feature was the development of congestive cardiac failure, which necessitated modification of her drug therapy).
