摘　　要：本文观察了心肌梗塞病人37例,年龄47～82岁。并随机选取正常人30例为对照组,年龄40～75岁。使用美国 HP-77020AC 型彩色多普勒超声诊断仪,分别测量左室舒张和收缩功能及室壁膨出与左室功能关系。结果显示:心肌梗塞患者与正常人相比,无论收缩功能,还是舒张功能均明显减低,二者差异极为显著。且心肌梗塞患者室壁膨出的多少与左室功能的各项指标均无相关性,进一步证明心肌梗塞患者测定左室功能的重要,同时对判定预后也有重要价值。本文还对心肌梗塞室壁膨出的机理以及梗塞后心腔扩大及室壁瘤的诊断进行了观察分析,对指导临床亦有重要价值。This paper reports the relationship of Left Ventrieu- lar (LV) geometry and function in the 30 normal sub- jects and 37 eases of acute myocardial infarction (AMI) by 2D-puled Doppler Ultrasonograph.The LV Function in the AMI,either diastolic or systolic,is lower than that in the normal subject,and this has statistical significance. The change of LV geonetry has no relation to LV func- tion in both diastolic and systolic.The results demonstrate that the estimation of LV function in AMI by echoeardio- graphy is a reliable method.
