心原性休克主要是指由于大面积心肌缺血或坏死后,心脏泵血功能严重受损,心输出量锐减所产生的以低血压、周围循环和组织低灌注并伴左心室充盈压增高为主要特征的临床综合征。长期以来,急性心肌梗死(AMI)并发心原性休克的发生率和病死率均无明显改善,仅到了90年代以后,随着介入 Cardiomyogenic shock is mainly due to a large area of ​​myocardial ischemia or necrosis, severe cardiac pump dysfunction, cardiac output caused by sharp drop in hypotension, peripheral circulation and tissue hypoperfusion and left ventricular filling pressure increased As the main feature of clinical syndrome. For a long time, there was no significant improvement in the incidence and mortality of acute myocardial infarction (AMI) complicated with cardiogenic shock. Only after the 90s,
