Besides determining systolic function through left ventricular ejection fraction (EF), color-Doppler ecocardiography evaluates the presence and degree of functional mitral regurgitation and the severity of diastolic dysfunction. Moreover, in addition to the aerobic capacity indicated by peak O2 consumption, other parameters of cardiopulmonary stress have proven useful for diagnostic purposes, such as the peak VE/VCO2 ratio or ventilatory efficiency...
