目的探讨主动脉球囊反搏(IABP)对急性心肌梗死(AMI)并发心源性休克(CS)患者的临床疗效。方法36例AMI并发CS的患者,均应用了IABP,应用DatascopeSystem97E型反搏仪,采用34～40ml型球囊,反搏时间15～168h。对其中30例患者进行选择性冠状动脉造影(Selectivecoronaryangiography,SCA),22例进行急诊经皮冠状动脉成形术(PTCA)和支架术,4例行冠脉旁路移植术(CABG)。结果36例患者中死亡12例,病死率为33.33%。其中行PTCA及CABG术死亡4例,占干预组病死率15.4%(4/26),未行介入及外科干预治疗的死亡8例,病死率80%(8/10)。结论使用IABP对AMI并发CS有显著的治疗效果,在IABP的支持下,积极进行血管重建治疗方能降低病死率。
Objective To investigate the clinical effect of aortic balloon pump counterpulsation (IABP) on patients with acute myocardial infarction (AMI) complicated with cardiogenic shock (CS). Methods Thirty-six patients with AMI complicated with CS were treated with IABP. DatascopeSystem97E countermeasure was used. The 34-40ml balloon was used. The counterpulsation time was 15-168 hours. Thirty patients underwent selective coronary angiography (SCA), 22 underwent emergency percutaneous transluminal coronary angioplasty (PTCA) and stenting, and 4 underwent coronary artery bypass grafting (CABG). Results Of the 36 patients, 12 died and the case fatality rate was 33.33%. Among them, 4 patients died of PTCA and CABG, accounting for 15.4% (4/26) of the patients in the intervention group, 8 patients died without intervention and surgical intervention, and the case fatality rate was 80% (8/10). Conclusions The use of IABP in the treatment of AMI with CS has a significant therapeutic effect. With the support of IABP, aggressive revascularization can reduce mortality.
