目的分析１４９６２例急性心肌梗死（ＡＭＩ）患者的临床特征。方法用ＳＡＳ６０４软件统计分析１４９６２例ＡＭＩ患者的４周总病死率和并发症。结果１４９６２例ＡＭＩ患者临床特征为：男性病人７３．９％；平均年龄６１．２±１０．７岁；有心肌梗死、高血压、糖尿病病史者分别占１２．２％，４０．４％，９．４％；基础血压１２６．６±２４．３／８１．３±１４．６ｍｍＨｇ；基础心率７９．３±１８．８ｍｉｎ－１。试验４周期间主要并发症心力衰竭为１７．９％，休克４．６％，心室颤动３．２％，其他类型的心跳骤停２．３％，Ⅱ～Ⅲ度房室传导阻滞５．２％，室性心动过速３．６％，梗塞扩展４．８％，脑卒中１．２％，心脏破裂０．５％。总病死率（２８ｄ）为９．４３％，死于泵衰竭为３．２５％，死于心律失常为４．５６％。
Objective To analyze the clinical features of 14962 patients with acute myocardial infarction (AMI). Methods SAS604 software was used to analyze the 4-week total mortality and complications of 14962 AMI patients. Results The clinical features of 14962 AMI patients were as follows: male patients 73.9%; average age 61.2 ± 10.7 years; patients with history of myocardial infarction, hypertension and diabetes accounted for 12.2%, 40.4%, 9 .4%; basal blood pressure 126.6 ± 24.3 / 81.3 ± 14.6mmHg; basal heart rate 79.3 ± 18.8min-1. The major complications during the 4-week trial were 17.9% with heart failure, 4.6% with shock, 3.2% with ventricular fibrillation, 2.3% with other types of cardiac arrest, and with Ⅱ-Ⅲ atrioventricular block. 2%, ventricular tachycardia 3.6%, infarct expansion 4.8%, stroke 1.2%, heart rupture 0.5%. The overall case fatality rate (28 days) was 9.43%, death from pump failure was 3.25% and arrhythmia was 4.56%.
