急性心肌梗塞经桡动脉冠状动脉介入治疗远期疗效

Long-term effect of delayed percutaneous coronary intervention via radial artery in patients with acute myocardial infarction

目的:探讨急性心肌梗塞(AMI)后延迟经桡动脉冠状动脉腔内成形术及支架术治疗的远期疗效。方法:133例AMI患者被分为经皮冠状动脉介入治疗组(PCI组)和非PCI组,PCI组于发病后平均13 d行PCI术。随访两组患者的心脏事件发生率。结果:随访期间,与非PCI组相比,PCI组患者主要不良心血管事件发生率明显降低(80%比27.3%,P<0.05),左室射血分数明显提高[(42±6.9)%比(57.4±3.5)%,P<0.05]。结论:急性心肌梗塞后延迟冠状动脉介入治疗可减少患者的心脏事件发生。

Objective： To study the long-term effect of delayed percutaneous coronary intervention （PCI） and percutaneous transluminal coronary angioplasty （PTCA） via radial artery in patients with acute myocardial infarction （AMI）. Methods： A total of 133 AMI patients were divided into PCI group and non-PCI group, patients in PCI group were given PCI on a mean 13 days after the onset. Major adverse cardiovascular events （MACE） of the two groups were followed up. Results： During follow up period, compared with non-PCI group, incidence rate of MACE （80% vs. 27.3%, P〈0.05） significantly decreased, teft ventricular ejection fraction [（42±6.9） % vs. （57.4±3.5） %, P〈 0.05] significantly increased in PCI group. Conclusion： Delayed percutaneous coronary intervention can significantly decrease cardiac events in patients with acute myocardial infarction.
