摘　　要：目的探讨急性心肌梗死合并心功能不全患者冠脉支架植入术及常规药物治疗后对患者心率变异性的影响。方法将120例急性心肌梗死合并心功能不全患者分为实验组和对照组各60例，实验组患者采用冠脉支架植入术治疗，对照组患者采用常规药物治疗，比较两组患者心率变异性。结果治疗1周及1个月后实验组平均正常RR间期的标准差（SDNN）、每5分钟正常RR间期平均值的标准差（SDANN）及其均值（SDNNindex）、相邻RR间期差的均方根（RMSSD）、相差50ms的相邻RR间期占RR间期总数的百分比（PNNS0）均较对照组升高，3个月后两组上述指标比较，差异具有统计学意义（P〈0．05）。结论冠脉支架植入术能有效改善心肌缺血和心率变异性，从而有效防止急性心肌梗死合并心功能不全患者发生恶性心律失常和心源性猝死。Objective To investigate the effect of percutaneous coronary intervention（PCl） and drug treatment on heart rate variability of patients with acute myocardial infarction complicated cardiac insufficiency. Methods 120 patients with acute myocardial infarction complicated cardiac insufficiency were divided into 2 groups. 60 patients of the experimental group were treated with PCI, and 60 of the control group were treated with traditional drugs. The heart rate variability between the 2 groups were compared. Results The SDABB, SDNN index, RMSSD, and PNN50 of the experimental group were higher than those of the control group after 1-week treatment and 1-month treatment, and the difference were statistically significant （P〈0.05） after 3 months treatment. Conclusion The myocardial ischemia and heart rate variability could be improved effectively in patients with acute myocardial infarction complicating cardiac insufficiency by PCI, and the malignant arrhythmia and cardiac sudden death be prevented effectively.
