摘　　要：以M型超声结合心电图、心音图对51例心肌梗塞(MI)病人、50例正常人左室顺应性(LVC)进行了观察,并与M型超声测定的其它心功指标(EPSS、EF、MVV、LVMI)作比较。结果表明MI后左室顺应性明显降低,其程度与MI范围、心功能状态有关,与MI部位无关。顺应性降低与以EF反映的收缩功能有一定联系,但二者改变的方向与程度不完全一致、顺应性异常出现早,发生率高,可能出现在正常收缩功能的情况下。顺应性降低是MI合并心功能不全的重要原因之一。EPSS、MVV一定程度上可反映顺应性改变。Left ventricular compliance (LVC) was determined in 51 patients with myocardisl infarction (MI) and 50 normal controls with M-mode echocardiography combined with electrocardiogram and phonocardiogram, and compared with other indices (EP SS, EF, MVV, LVMI) of left ventricular function. The results showed LVC was markedly decreased in MI, extent of which was associated with MI size, ventricular function, not with the location of MI. There was relationship between LVC and left ventricular systolic function but not identical with the extent and direction of their changes. The abnormality of LVC had a higher incidence and may be present in normal systolic function. Reduction of LVC was one of the important causes of left ventricular failure in MI patients. To some extent, EPSS and MVV might reflectthe changes of LVC.
