AMI使左心室功能遭受损害而引起的严重循环衰竭,称AMI休克。约半数发生在AMI24小时内,是最常见的一种致命性并发症,约占住院AMI病人的10～15%,其病死率高达70～100%。一、AMI休克的特点及临床诊断AMI休克主要是由于心排血量急剧下降,导致血液动力学异常改变而表现的一组临床症候群。典型的血液动力学特征为:体循环压力<80/50mmHg,平均动脉压<60mmHg,平均中心静脉
AMI causes left ventricular dysfunction caused by severe circulatory failure, said AMI shock. About half of AMI occurred in 24 hours, is the most common fatal complications, accounting for about 10 to 15% of hospitalized patients with AMI, the mortality rate as high as 70 to 100%. First, the characteristics of AMI shock and clinical diagnosis of AMI shock is mainly due to a sharp decline in cardiac output, resulting in abnormal changes in hemodynamic manifestations of a group of clinical syndromes. Typical hemodynamic characteristics are: systemic pressure <80 / 50mmHg, mean arterial pressure <60mmHg, mean central venous pressure
