目的:评价急性心肌梗死( AMI) 病人择期行经皮冠状动脉介入术( PCI) 对心率变异性( HRV) 的影
响。方法: 52 例AMI 病人以行择期PCI 分为对照组( 药物保守治疗) 和PCI 组( 成功行择期PCI) ，对比PCI 前、
术后1mo 及术后6mo HRV 相关指标。结果:与药物保守治疗组比较，施行择期PCI 病人术后1mo、6mo HRV 改
善明显( P＜0． 05) 。PCI 术后1mo 与6mo 相比HRV 有改善，但无统计学意义( P＞0． 05) 。结论: 择期PCI 可以改
善AMI 病人的HRV，有助于恢复心脏自主神经的恢复。

Objective: To evaluate acute myocardial infarction( AMI) patients undergoing elective
percutaneous coronary intervention( PCI) on heart rate variability( HRV) ． Methods: 52 patients with
AMI were divided into a control group( conservative treatment) undergoing elective PCI and PCI group
( successful elective PCI ) ，compared to PCI ago，after 1mo and 6mo HRV indicators． Results:
Compared with conservative medical treatment group， the purposes of elective PCI in patients with postoperative
1 Mo 6moHRV improved significantly( P＜0． 05) ． After PCI 1 Mo 6mo HRV has improved，
but not statistically significant( P＞0． 05) ． Conclusion: The elective PCI can improve the HRV in patients
with AMI，help to restore cardiac autonomic nerve recovery．
