主动脉球囊反搏术在急诊冠状动脉介入术中的应用研究

Research on the intra-aortic balloon pump in the emergency coronary intervention

目的 观察主动脉球囊反搏术在急诊冠状动脉介入术中的应用效果.方法 2011年1月1日至2013年10月1日,选择在齐齐哈尔医学院附属第三医院心内科行急诊经皮冠状动脉介入术的急性心肌梗死合并心源性休克患者76例作为研究对象,其中观察组41例,行主动脉内球囊反搏术（intraaortic balloon pump,IABP）,对照组35例没有采用IABP,比较2组患者左室射血分数（left yen-tricular ejection fraction,LVEF）及射血分数（ejection fraction,EF）改善率（术后EF/术前EF）,以及IABP术后并发症发生情况.结果 2组患者术后24h内LVEF变化、EF改善率、收缩压和舒张压比较具有统计学意义;在手术6个月后,LVEF变化以及患者死亡例数比较具有统计学意义.结论 对于存在血流动力学障碍的急性心肌梗死患者行经皮冠状动脉介入术时,及时进行主动脉内球囊反搏术,能有效改善患者的LVEF,有效提高患者的血压水平,降低患者的死亡率.

Objective To observe the application effect of intra-aortic balloon pump （IABP） in the emergency coronary intervention.Methods 76 cases patients with acute myocardial infarction complicated with cardiogenic shock were selected in the Third Affiliated Hospital of Qiqihar Medical University.41 cases in the observation group used IABP,35 cases in the control group did not use the IABP.The left ventricular ejection fraction （LVEF）,ejection fraction improvement rate （postoperative EF/pre-operative EF）,and the incidence of postoperative complications of IABP were compared between two groups.Results LVEF changes,the rate of improvement in ejection fraction,systolic and diastolic blood pressure were statistically significant; after six months,LVEF changes and the number of cases of death in patients were also statistically different between two groups.Conclusions For the patients with AMI and hemodynamic disorders undergoing PCI,timely IABP can effectively improve the patients’ left ventricular ejection fraction,improve the patients’ blood pressure levels and reduce mortality rate of patients.
