In HYPERTROPHIC CARDIOMYOPATHY myocardial ischaemia arises because the INTRAMURAL ARTERIOLES ARE NARROWED BY MEDIAL AND INTIMAL FIBROSIS AND THICKENING (small vessel disease), together with the increased muscle mass, raised filling pressures and reduced capillary density - angina occurring with normal epicardial coronary arteries.
