摘要
对65例不同部位陈旧性心肌梗塞(OMI)患者采用频域和时域法分析经皮腔内冠状动脉成形术(PTCA)前、后的心率变异性(HRV),旨在了解不同部位OMI患者HRV的变化及PTCA术对患者自主神经系统的影响。结果:不同部位OMI患者的HRV无明显差异,而PTCA术后HRV指标中的高频段(HF)、标准差均较术前增加,低频段(LF)及LF/HF较术前降低。说明PTCA术后交感神经活性降低,迷走神经活性增强。提示PTCA术后可能改善冠心病患者的远期预后。
Heart rate variability(HRV) was analyzed in 65 patients with old myocardial infarction before and after percutaneous transluminal coronary angioplasty(PTCA),in order to observe whether there was a relation between HRV and the site of myocardial infarction and to observe the effect of PTCA on autonomic nervous system,The results showed that there was no significant difference between HRV and the infarct site before and after PTCA,but HF,SDNN were significantly increased and LF,LF/HF were significantly reduced at six months after PTCA compared with that before PTCA (P<0.05 in all).It suggested that the sympathetic activity was diminished and the vagal activity was raised after PTCA.It was possible that successful PTCA could improve the longterm prognosis of patients.
