摘要
对经核素心室造影证实的４０例老年左室舒张性心力衰竭（ＬＶＤＨＦ）和３０例老年左室收缩性心力衰竭（ＬＶＳＨＦ）患者进行临床、超声心动图观察及活动平板运动试验，并以２０例健康老年人作对照，评价左室舒张性心力衰竭临床、超声心动图及运动耐量的特点。结果显示：ＬＶＤＨＦ组心衰时间短，心衰临床表现较轻；超声左房内径扩大，左室内径不大，左室壁厚度增加；左室收缩功能正常，左室舒张功能减低。而ＬＶＳＨＦ组左室内径扩大，左室收缩、舒张功能指标均异常。ＬＶＤＨＦ和ＬＶＳＨＦ两组运动耐量均减退，后者尤为明显。
Forty aged patients with LVDHF and 30 with left ventricular systolic heart failure (LVSHF), confirmed by radionuclide ventriculogrpahy 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.
