目的观察主动脉内球囊反搏术(IABP)应用于急性心肌梗死冠状动脉介入治疗术后心功能衰竭的疗效。方法28例急性心肌梗死行急诊经皮冠状动脉介入术(PCI)后合并急性左心力衰竭患者,静脉使用血管活性药物仍不能维持有效血液循环,经股动脉置入主动脉内球囊反搏导管,行IABP。观察尿量、心率、意识改变、有创动脉收缩压(SABP)和平均动脉压(MABP)。结果IABP后,患者SABP、MABP明显高于术前(P<0.01)。23例患者心功能均有不同程度改善,心率减慢,尿量增多,心功能改善不明显3例,死亡2例。结论主动脉内球囊反搏术能有效改善PCI术后低心排血量病人的心功能。
ObjectiveTo evaluate the effect of intro-aortic balloon pump(IABP) for acute myocardial infarction (AMI) complicated with heart failure after percutaneous coronary intervention (PCI).Methods28 patients with AMI were complicated with acute heart failure after PCI.When effective circulation could not be maintained by vasoactive agents,the catheter was put into by arteria femoralis approach.Volume of urine,heart rate and consciousness were monitored.Systolic arterial blood pressure(SABP) and mean arterial blood pressure(MABP) were measured.ResultsAfter IABP,SABP,MABP were significantly improved than those before(P<0.01).Heart rate was slower and the volume of urine was increased after IABP.ConclusionIABP could improve cardiac function effectively after PCI.
