左室收缩性与舒张性心力衰竭的超声左心形态,功能的对比研究

对８５例左室舒张性心力衰竭病例进行Ｍ型、二维、多普勒超声心动图检测，２０例正常人作对照（ＣＧ），观察其收缩性，舒张性心力衰竭左心形态和功能的特点。结果表明：左室舒张性心力衰竭组（ＬＶＤＨＦ）与左室收缩性心力衰竭组（ＬＶＳＨＦ）比较，左房内径（ＬＡＤ），左室内径（ＬＤＶ）、左室重量指数（ＬＶＭＩ）显著减低，室间隔厚度（ＩＶＳＴ）、左室后壁厚度（ＰＷＴ）明显增加；与ＣＧ组比较，ＬＶＤＨＦ组ＬＡＤ，ＩＶ

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.
