摘要
目的 观察经皮腔内冠脉成形术 (PTCA)后再狭窄与无再狭窄患者的心率变异 (HRV)变化 ,探讨PTCA术对心脏自主神经活动的影响及HRV变化与再狭窄的关系。方法 对PTCA术患者 5 1例 ,其中再狭窄者 34例 ,无再狭窄者 17例 ,分别于术前 1周、术后 1周、术后 6个月记录 2 4h心电信号并进行HRV时域法和频域法分析。结果 (1)所有患者PTCA术后 1周HRV值均较术前降低 (P <0 0 5 ) ;(2 )PTCA术后 6个月冠脉再狭窄患者的HRV值有继续降低趋势 ,而无再狭窄患者的HRV值有所增大 ,但尚未达统计学意义。结论 PTCA术早期对患者心脏自主神经活动的平衡有一定影响 ,PT CA术后再狭窄者的HRV有降低趋势 。
Objective To observe the relation between heart rate variability (HRV)and restenosis after percutaneous transluminal coronary angioplasty(PTCA).Methods Time and frequency domain measures of HRV were analyzed from 24-hour ambulatory electrocardigraphic recordings. HRV was performed in 51 patients at one week before PTCA,and one week and six months after PTCA.Results HRV at one week after PTCA was significantly decreased in comparison with that before PTCA (P<0 05)。HRV in restenosis group was continuously decreased,and HRV in nonrestenosis group was increased at six months after PTCA. Conclusion Autonomic nervous system activity may be impaired early after PTCA.
