Value of a comprehensive exercise echocardiography assessment for patients with hypertrophic cardiomyopathy

Background: Exercise echocardiography (ExE) may assess left ventricular (LV) systolic and diastolic function, LV outflow tract (LVOT) obstruction, and mitral regurgitation (MR). We aimed to evaluate the prognostic value of these assessments during exercise in patients with hypertrophic cardiomyopathy (HCM).Methods: LV systolic function, LV-derived filling pressures, LVOT gradients, and MR were prospectively evaluated during treadmill ExE in 285...
