目的探讨心率震荡与冠心病患者冠脉病变程度的关系。方法选择在我院行冠脉造影术的患者255例,根据冠脉造影结果分为冠心病组和冠脉正常组,冠心病组分为单支病变组,两支病变组和多支病变组,采集病史,计算心律震荡指标,Gensini积分,统计分析各组间各项指标。结果①冠心病组患者心率震荡指标TO高于正常组,TS低于正常组;②TO多支病变组高于两支病变组和单支病变组,TS多支病变组低于两支病变组和单支病变组;③回归分析显示TS对冠脉Gensini积分的影响最大。结论冠心病患者心率震荡减弱,且随着冠脉病变程度的加重,心率震荡减弱越明显,提示植物神经功能紊乱的加重。
Objective To investigate the relationship between heart rate turbulence and coronary artery disease in patients with coronary artery disease. Methods 255 patients undergoing coronary angiography in our hospital were divided into coronary heart disease group and normal coronary artery group according to the results of coronary angiography. The coronary heart disease group consisted of single-vessel disease group, two-vessel disease group and multi-vessel disease group , Collected medical history, calculated cardiac rhythm and shock indicators, Gensini points, and statistically analyzed the various indicators among the groups. Results ① Heart rate index (TO) of coronary heart disease group was higher than that of normal group and TS was lower than that of normal group. (2) TOH multi-vessel disease group was higher than two-vessel disease group and single vessel disease group, TS multi-vessel disease group was lower than two vessel disease group Single vessel disease group; ③ Regression analysis showed that coronary artery Gensini score the greatest impact. Conclusion Heart rate turbulence in patients with coronary heart disease weakened, and with the severity of coronary artery disease, heart rate turbulence weakened more obvious, suggesting that autonomic dysfunction worsened.
