[Comparative study of left ventricular morphology and function of patients with left ventricular systolic and diastolic heart failure on echocardiography].

Left ventricular pathology and pathophysiological characteristics of fifty patients with left ventricular diastolic heart failure (LVDHF), and 35 patients with left ventricular systolic heart failure (LVSHF) diagnosed by clinical manifestations and radionuclide ventriculography, were examined by echocardiography and 20 healthy persons were served as control group. Left atrial diameter (LAD), interventricular septum thickness (IVST) and posterior wall thickness (PWT) and left ventricular mass index (LVMI) were significantly increased in the patients with LVDHF, while left ventricular diameter (LVD) was significantly increased in the patients with LVSHF. Left ventricular ejection fraction (LVEF), cardiac index (CI) were significantly decreased in the patients with LVSHF. Early peak filling velocity (EPFV), atiral peak filling velocity (APFV), deceleration of early peak filling velocity (DC) and isovolumic relaxation time (IRT) in the patients with LVDHF and LVSHF observed no significant difference.
