[Clinical study on left ventricular diastolic heart failure in the aged patients].
Forty aged patients with LVDHF and 30 with left ventricular systolic heart failure (LVSHF), confirmed by radionuclide ventriculography were studied by clinical, echocardiography and treadmill test. Twenty healthy aged persons were served as control group. Compared with LVSHF, short duration and less severe manifestations of heart failure in LVDHF were observed. Compared with the control, left atrium was enlarged but not the left ventricular chamber, and LV wall was thickened in LVDHF, while enlargement of LV chamber was only found in LVSHF. However, LV systolic function was remained normal in LVDHF. The exercise tolerance was decreased in both LVDHF and LVSHF groups, but more marked in LVSHF.
