The association between the left ventricular (LV) systolic and diastolic indexes and conventional echocardiography cardiac function measurements. The LV systolic index well positively correlated with ejection fraction (EF), and the diastolic index moderately positively correlated with early diastolic mitral annular velocity (Ea) and negatively with the ratio of peak early filling velocity divided by Ea (E/Ea).
