急性大面积ST段抬高型心肌梗死患者早期床旁应用主动脉内气囊反搏术预后观察

目的:研究急性大面积ST段抬高型心肌梗死(STEMI)患者在择期经皮冠状动脉介入治疗(PCI)前尽早床旁应用主动脉内气囊反搏术(IABP)对预后的观察。方法:选取发病12～72h的STEMI患者150例,随机分为2组,IABP组72例,对照组78例,2组均给予规范的药物治疗,IABP组同时床旁应用IABP。2组均于发病10～14d行冠脉造影,必要时行PCI术,评价梗死相关血管PCI术前及术后冠脉血流,术后4周心功能、IABP主要不良心脏事件的发生情况。结果:2组患者PCI术前TIMI血流、PCI术后4周主要不良心脏事件的发生率、左心室射血分数(LVEF)均有显著性差异(P<0.05)。结论:对于急性大面积STEMI患者择期行PCI,尽早床旁应用IABP能改善梗死相关血管的TIMI血流,改善心功能,减少主要不良心脏事件的发生率,临床应用安全可行。

Observation on the prognosis of early application of bedside intra-aortic balloon pump counterpulsation in patients with acute ST-segment elevation myocardial infarction

Objective: To evaluate the effect of early application of intra-aortic balloon pump counterpulsation (IABP) on prognosis of patients with acute ST-segment elevation myocardial infarction (STEMI) before elective percutaneous coronary interventional (PCI). Methods: One hundred and fifty patients with STEMI were randomly divided into two groups: 72 patients in IABP group and 78 in control group. All patients in IABP group receiving bedside IABP support treatment while patients in control group do not. All patients were performed PCI after 10 to 14 days. The blood flow rate of infart related coronary vessel was observed before and after PCI. The major adverse cardiac events (MACE) and heart function at 4 weeks were studied. Results: In IABP group, blood flow rate of related coronary vessel, the occurance of MACE at 4 weeks, left ventricle ejection fraction (LVEF) were significant different in two groups (P<0.05). Conclusions: Early application of IABP for patients with STEMI before elective PCI is safe and effective, which can reduce the incidence of MACE, and improve heart function.
