新近心肌梗死时出现的心源性休克可按预后的不同分为两组:①“早发型”休克,发生于梗死后的最初数小时之内;②“迟发型”休克,在梗死后的头几天乃至数周之内才逐渐发生。前者对“主动脉内递搏动气囊泵”,(Intra-aortic phase-sbift balloon pumping)反应良好,而后者则不然,病死率可达100%。据称,心肌梗塞时“早发型”休克和“迟发型”休克各占50%左右。
New cardiogenic shock during myocardial infarction may be divided into two groups according to prognosis: ① “early-onset” shock occurred within the first few hours after infarction; ② “delayed-type” shock, after the head of infarction A few days or even gradually occur within a few weeks. The former responded well to Intra-aortic phase-sbift balloon pumping, while the latter did not. The mortality rate was 100%. Allegedly, myocardial infarction, “early-onset” shock and “delayed-type” shock each account for about 50%.
