【目的】探讨心率变异性（HRV）对变异性心绞痛患者冠脉病变的评估价值。【方法】回顾性分析本院2011年1月至2014年12月收治的96例变异性心绞痛患者，根据冠脉造影结果进行分组，冠状动脉直径减少≥50％为有意义病变组，冠状动脉直径减少＜50％为无意义病变组；有意义病变组中显示为左回旋支、左前降支、右冠状动脉有一支病变则为单支病变组，左回旋支、左前降支、右冠状动脉有两支或两支以上病变或单纯左主干病变则为多支病变组。单支病变组中冠脉狭窄≥75％为重度狭窄组，冠脉狭窄50％～75％为轻中度狭窄组。【结果】有意义病变组 H RV指标均低于无意义病变组，差异具有统计学意义（ P ＜0．05）；多支病变组H RV指标均低于单支病变组，差异具有统计学意义（ P ＜0．05）；重度狭窄组 H RV指标均低于轻中度狭窄组，差异具有统计学意义（ P ＜0．05）。【结论】通过对变异性心绞痛患者进行 HRV分析，可以了解冠状动脉病变程度，对评估病情和诊治变异性心绞痛有重要意义。“,”[Objective]To explore the assessment value of heart rate variation (HRV) in patients with va‐riant angina pectoris of coronary artery disease .[Methods] Retrospective analyses from January 2011 to De‐cember 2011 were conducted for 96 patients of variant angina pectoris .According to the results of coronary contrast imaging ,the patients with coronary diameter ≥50% were assigned into meaningful lesion group while those with coronary diameter <50% insignificant lesion group .Significant pathological changes of single le‐sion were evident for left circumflex branch ,left anterior descending branch and right coronary artery .And left circumflex branch or right or left anterior descending coronary artery had two lesions or simply left main lesion with multiple (two or more) lesions .Single lesion of coronary artery stenosis 75% or higher denoted se‐vere stenosis while 50% ~75% mild‐to‐moderate stenosis .[Results] There were insignificant ( n =65) and significant ( n=31) lesion groups .And the inter‐group differences in HRV were statistically significant ( P<0 .05) .The values of HRV were lower in multi‐lesion group than single‐lesion group .And the differences were statistically significant ( P <0 .05) .The values of HRV were lower in severe stenosis group than mild‐to‐moderate stenosis group .And the differences were statistically significant ( P <0 .05) .[Conclusion] For variant angina pectoris patients ,analyses of HRV helps us gauge the degree of coronary artery lesions ,assess severity and guide their diagnoses and treatments .
