摘　　要：目的：评估急性心肌梗死（AMI）患者经皮冠状动脉介入（PCI）对心率变异的影响。方法：44例AMI住院患者为PCI组18例，和非PCI组26例，PCI组行冠状动脉内支架植入术，非PCI组给药物治疗，两组在7—10日内行24h动态心电图检查。分析SDNN、SDANN、RMSSD、PNN50、LF、HF指标的变化。结果：行PCI治疗的AMI患者心率变异指标有明显改善而对照组无变化。结论：对心肌梗死患者及早行PCI，可使患者的心率变异指标显著增加，明显改善患者预后。Objective：To evaluate the influence of percutaneous coronary intervention （PCI） on heart rate variance in acute myocardial infarction （AMI） patients. Methods：44 AMI patients were divided into two groups. 18 patients received PCI and the other 26 patients re- ceived drug treatment. All of the patients received 24 hours ambulant electrocardiogram exam in 7 - 10 days. The standard deviation of normal to normal interval（ SDNN ）,standard deviation of average normal to normal interval （SDANN）, root mean square values of the standard deviation between adjacent normal to normal interval （ RMSSD）, percentage of differences exceeding 50ms between adjacent normal to normal interval（ PNNS0 ）, low frequency （LF）, high frequency （HF） were examined and analyzed by t-test. Results： The heart rate variance indexes of AMI patients received PCI were improved significantly. Conclusion： Early PCI in AMI patients can increase the heart rate variance indexes significantly and improve the prognosis dramatically.
