急性心肌梗塞病人心梗范围对早期并发症和死亡率的影响

Correlation between Infarct Size and Early Complications and Mortality in Acute Myocardial Infarction Patients

按Ｗａｇｎｅｒ的ＱＲＳ评分法将１５１例急性心肌梗塞病人分为大范围组（６６例外）和小范围组（８５例）。大范围组临床心功能分级、Ｋｉｌｌｉｐ分级均比小范围组严重，心源性休克发生率高于后者，超声心动图测定的左室功能也比后者差。大梗塞组２５例早期死亡（３８％），小梗塞组７例（８５％）（Ｐ＜０．００１）。

One hundred and fifty-one cases of acute myocardial infarction were divided into large infarct size group(66 cases) and small infarct size group (85 cases). The clinical cardiac function scoring and Killip's scoring were more severe in large infarct size group than in small infarct size group.The occurrence of cardiac shock was higher in large infarct size group than in small infarct size group. The left ventricular systolic function determined by echocardiography was poorer in large infarct size group than in small infarct size group.There were 25(38%) cases of early death in large infarct size group and 7(8%) cases in small infarct size group(P<0. 001).
