急性心肌梗死合并心源性休克的特点及预后

目的 观察再灌注治疗时代急性心肌梗死(AMI)合并心源性休克(CS)积极干预治疗对预后的影响.方法 连续入选AMI合并cs的患者89例,保守治疗50例,再灌注治疗39例,其中再灌注成功28例,不成功11例.早置组18例,CS发生1 h内放置主动脉内球囊反搏(IABP)晚置组35例,1 h后放置IABP未放置IABP组36例.结果 IABP早置组病死率明显低于晚置组和未置组(33.3%、74.2%、86.1%,P＜0.01).再灌注成功组病死率明显低于再灌注不成功和保守治疗组(42.8%、81.8%、84.0%,P＜0.01).logistic回归分析显示IABP放置时机(OR 0.22,95% CI 0.063～0.764,P=0.017)和成功再灌注(OR 4.232,95% CI 1.407～12.730,P=0.01)是死亡相关的独立危险因素.结论 积极成功再灌注和尽早应用IABP是降低AMI合并心源性休克病死率的重要和有效治疗措施.

The clinical characteristics and prognosis of acute myocardial infarction complicated by cardiogenic shock

Objective To observe the effect of reperfusion therapy on the prognosis of acute myocardial infarction (AMI) complicated by eardiogenic shock(CS)in reperfusion era.Methods 89 cases of AMI with CS were included with 57 male and 32 female.50 cases received conservative therapy and 39 cases reperfusion therapy.28 of the 39 cases had suecessflll reperfusion and 11 eases failed.18 patients had intra-aortic balloon pump (IABP) within 1 hour of CS,they constituted an early group;35 patients treated with IABP 1 hour after CS were of a late group.A group of 36 cases were not treated with IABP (no IABP group).Results The mortality of the early group with IABP Was significantly lower than that of the late and no IABP group(33.3% vs.74.2% vs.86.1%,P＜0.01).The mortality of the group with sucessful reperfusion was significantly lower than that of unsuccessful reperfusion and conservative no IABP group (42.8% vs.81.8% vs.84.0%,P＜0.01).logistic regression analysis showed that successful reperfusion therapy (OR 4.232,95% CI 1.407～12.730,P=0.01) and THE TIME of using IABP(OR 0.22.95% CI 0.063～0.764,P=0.017)were independent risk factors for death.Conclusion Early successful reperfusion and early institution of IABP were the most important therapeutic measures for reducing mortaliIv of AMI complicated by CS.
