Comparison of transmitral E to lateral Ea ratio in patients with hypertrophic cardiomyopathy with different capacity for exercise. Three groups of the patients were distinguished: those with peak oxygen consumption (PVo₂; ml/kg/min) > 30, those with PVo₂ between 20 and 30, and those with PVo₂ < 20. The patients with PVo₂ < 20 had significantly higher transmitral E to lateral Ea ratio than those with PVo₂ > 30. NYHA, New York Heart Association; transmitral E/lateral Ea, ratio of transmitral early left ventricular filling velocity to early diastolic velocity of the lateral mitral annulus.
