Usefulness of Mitral Annular Velocity in Predicting Exercise Tolerance in Patients With Impaired Left Ventricular Systolic Function

Usefulness of Mitral Annular Velocity in Predicting Exercise Tolerance in Patients With Impaired Left Ventricular Systolic Function

Left ventricular (LV) diastolic function is 1 of the determinants of exercise tolerance. However, the relation between early diastolic velocity of the mitral annulus (Ea) obtained by tissue Doppler imaging and exercise tolerance is unknown in patients with impaired LV systolic function. To investiga...

Zusammenfassung:Left ventricular (LV) diastolic function is 1 of the determinants of exercise tolerance. However, the relation between early diastolic velocity of the mitral annulus (Ea) obtained by tissue Doppler imaging and exercise tolerance is unknown in patients with impaired LV systolic function. To investigate the feasibility of evaluating exercise tolerance using tissue Doppler imaging, we studied 53 consecutive patients (mean age 58 ± 14 years) with a LV ejection fraction of
