目的研究三酰甘油与高密度脂蛋白胆固醇比值（TG／HDL—C）与冠心病的发病及其冠状动脉（冠脉）狭窄程度的关系。方法158例冠心病患者根据选择性冠脉造影证实将其分为对照组和冠脉狭窄组（狭窄组），狭窄组分为单支病变组，双支病变组和多支病变组。评估危险因素与冠脉病变支数的关系，Gensini评分评价冠脉病变狭窄程度。结果狭窄组患者较对照组TG／HDL—C比值升高，分别为1．8±1．0、1．7±1．4（T=2．68，P〈O．05）；随着冠脉病变程度的加重，TG／HDL—C比值呈逐渐升高趋势，多支病变组患者TG／HDL—C比值升高（P〈0．05）。多支冠脉病变与总胆固醇（TC）、低密度脂蛋白胆固醇（LDL—c）、TG／HDL—C呈正相关（口值分别为0．326、0．339、0．158，均P〈O．05）。结论TG／HDL—C比值与多支冠脉病变相关。但该比值的临床意义较其他指标无更强的相关性。
