摘要
目的 该文选择成功地行择其经皮腔空冠状动脉成形术的首次急性心肌梗死患者 ,进行心率变异检查 ,以了解择期PTCA对心率变异性的影响。方法 所有患者均于PTCA术前 1,2d及术后 1周、3个月进行2 4hHolter记录。HRV检查方法包括长时程 2 4h时域分析 (重取SDNN)和短时程 5min频域分析 (采取LFnorm、HFnorm和LF/HF)。结果 PTCA术后 1周与术前相比无明显变化。PTCA术后 3个月与术前相比有显著差异 ,其中SDNN、HFnorm和LFnorm有明显增高 (P <0 .0 5 ) ,LF/HF有明显降低 (P <0 .0 5 )。结论 AML接受择期PTCA有益于患者心率变异性的恢复 ,术后一周改善不显著 ,至术后 3个月有显著 ,至术后 3个月有显著改善。
Objective: To observe the effects of elective percutaneous transluminal coronary angioplasty (PTCA) on heart rate variability (HRV) in patients with first AMI.Methods: Thirty-eight patients with first AMI underwent successful elective PTCA. Three-channel and 24hour ambulatory electrocardiograms were performed 1～2 days before PTCA and a week and three months after PTCA. 24hour time domain and 5minute frequency domain analyses were adopted in measuring HRV.Results: Compared with the values of HRV before PTCA, those of HRV one week after PTCA had no significant difference. But the values of HRV three months after PTCA revealed a significant change.Conclusions: Successful elective PTCA can improve HRV in patients with first AMI.
