目的探讨主动脉内球囊反搏术(intra aortic balloon counterpulsation,IABP)支持下急性心肌梗死合并心源性休克患者行急诊介入治疗的临床疗效。方法 20例急性心肌梗死合并心源性休克患者在IABP支持下行急诊PCI治疗,分析其疗效及安全性。结果 20例患者中18例(90%)直接PCI操作成功,IABP持续12-230h,余2例(10%)失败,继续药物治疗,无术中死亡。15例病情稳定出院,住院时间8-50d,住院期间死亡5例,包括2例直接PCI失败患者,均死于急性心肌梗死并发心源性休克。结论 IABP支持下的急诊介入治疗能显著提高急性心肌梗死合并心源性休克患者的生存率,疗效显著。
Objective To investigate the clinical effect of emergency interventional therapy in patients with acute myocardial infarction complicated with cardiogenic shock supported by intra-aortic balloon counterpulsation (IABP). Methods Twenty patients with acute myocardial infarction complicated by cardiogenic shock underwent emergency PCI with IABP support. The efficacy and safety were analyzed. Results Of the 20 patients, 18 (90%) patients underwent direct PCI, IABP continued for 12-230 hours, and the remaining 2 patients (10%) failed to continue the drug treatment without any intraoperative death. Fifteen patients were discharged in stable condition, hospitalized for 8-50 days, and 5 died during hospitalization, including 2 patients with direct PCI failure, all of whom died of cardiogenic shock due to acute myocardial infarction. Conclusion The IABP-supported emergency intervention can significantly improve the survival rate of patients with acute myocardial infarction complicated by cardiogenic shock.
