急性心肌梗死急诊介入治疗对心功能的影响

目的：探讨急性心肌梗死（AMI）后行急诊经皮冠状动脉成形术（PCI）和行择期PCI治疗的近期疗效和安全性。方法：248例AMI患者被分为两组,急诊PCI组19例,择期PCI组229例。对两组患者住院期间用药情况及PCI后心功能进行分析。结果：两组患者术后心功能各项指标均明显改善,与择期PCI组相比,急诊PCI组左室射血分数明显提高[（52.7±6.3）%比（54.1±2.7）%],左室舒张末内径明显减小[（48.8±1.7）mm比（47.8±2.4）mm],P均〈0.05。结论：急性心肌梗死后行急诊经皮冠状动脉成形术是一种安全有效的介入性治疗手段,可以防止再梗死和心肌缺血,进一步改善心功能。

Influence of primary percutaneous coronary intervention on cardiac function after acute myocardial infarction

Objective:To study short-term therapeutic effects and safety of primary percutaneous coronary intervention(PCI) and delayed PCI after acute myocardial infarction(AMI).Methods:A total of 248 AMI cases were divided into primary PCI group(n=19) and delayed PCI group(n=229).Medicinal treatment during admission and cardiac function after PCI were recorded,compared and analyzed between the two groups.Results:Parameters of cardiac function significantly improved after PCI in both groups.Compared with delayed PCI group after treatment,there was significant increase in left ventricular ejection fraction [(52.7±6.3)% vs.(54.1±2.7)%]and significant decrease in left ventricular end-diastolic dimension [(48.8±1.7) mm vs.(47.8±2.4) mm]in primary PCI group,P<0.05 both.Conclusion:Primary percutaneous coronary intervention after acute myocardial infarction is a safe and effective interventional treatment.It can prevent re-infarction and cardiac ischemia,improve cardiac function.
