急性心肌梗死(AMI)的严重并发症心源性休克(CS),其发生率在5%～15%,保守治疗病死率高达91%[1],早期及时再灌注治疗病死率下降至17.6%～50.0%[2]。因此,病死率直接与临床治疗时机的选择和治疗方式不同高度相关。为进一步了解AMI患者合并CS的发病特点、病死率 Acute myocardial infarction (AMI) is a serious complication of cardiogenic shock (CS), with a rate of 5% to 15% and a conservative treatment mortality of up to 91% [1]. Early and immediate reperfusion mortality declined to 17.6% ~ 50.0% [2]. Therefore, the mortality is directly related to the choice and treatment of timing of clinical treatment. In order to further understand the incidence of AMI patients with CS characteristics, mortality
