急性心肌梗塞住院病死率的比较分析

Comparative analysis of in-hospital mortality of acute myocardial infarction in Tianjin

对我院１９８１～１９８３年１３４例和１９９１～１９９３年３０８例急性心肌梗塞病人的资料作比较，以了解天津部分地区１０年间该病病死率及其影响因素的改变。结果表明，住院病死率从２２．４／降至１５．６％，尚无统计学差异（Ｐ＞０．０５），其中男性病人病死率降低较明显（Ｐ＜０．０５）。有利于病死率降低的因素为：年龄＜６０岁，初发梗塞和心脏骤停抢救成功率；不利因素为合并高血压和（或）糖尿病。１９９１～１９９３年组接受溶栓治疗者１１２例。溶栓率达３６．４％。１０年间药物治疗的内容发生显著改变，反映了对本病认识的概念模式上的巨大转变。

Abstract The patients with acute myocardial infarction (AMI) treated at the Second Affiliated Hospital of TianJin Medical College were compared between 134 cases in 1981 to 1983 and 308 cases in 1991 to 1993 for the in-hospital mortality and the related factors. The results showed that the overall in-hospital mortality reduced from 23. 4% to 15. 6%, but not significantly different (P>0. 05 ). The male patients mortality decreased from 23. 7% to 13.1% (P<0.05). Univariate factor analysis suggested that age (<60 years), first at tack, thrombolytic therapy within 6 hours after onset and success in resuccitation are favorable variables. A history of hypertension and/or diabetes mellitus are unfavorable factors. The drugs used in AMI changed obviously in the last decade. It may reflect the great progress in understanding the disease.
