甘油三酯/高密度脂蛋白胆固醇比值对老年冠心病诊断价值的探讨

The predictive value of TG/HDC-C ration for geriatric coronary heart disease risk

目的 :探讨甘油三酯 /高密度脂蛋白胆固醇 (TG/ HDL- C)比值对老年冠心病 (CHD)的诊断价值。方法 :分析 34 2例选择性冠状动脉造影 (冠脉造影 )确诊的老年 CHD患者 (CHD组 )及 96例冠脉造影阴性老年人 (对照组 )的 TG/ HDL - C比值水平与 CHD之间的关系。结果 :CHD组患者的 TG/ HDL - C比值水平及异常率均明显高于对照组 (2 .5 4± 1.2 9比 1.32± 1.16 ,P<0 .0 0 1,35 .6 %比 13.7% ,P<0 .0 0 1)。经多元逐步回归分析显示 :与 TG、HDL - C相比 ,该比值与 CHD之间显示了更有意义的回归关系 (β值 0 .32 ,P值 =0 .0 0 0 1,复相关系数为 0 .5 5 )。结论 :TG/ HDL- C比值对于老年

Objective:To study the significance of serum triglycerin/high density lipoprotein cholesterol(TG/ HDL C ) ratio in predicting geriatric coronary heart disease(CHD) risk.Methods:TG/HDL C ratio were analysed in 438 geriatric cases underwent coronary angiography,who were positive in 342 geriatric patients(CHD group),and negative in 96 cases (normal control group).Results:TG/HDL C ratio and its abnormal rate were significantly higher in patients with CHD than those of the normal control group(2 54±1 29 vs 1 32±1 16, P <0 001,35 6% vs 13 7%, P <0 001).Multivariate regression analysis revealed that the ratio was a signigicant variable realted with CHD compared with either TG or HDL C.Conclusion:TG/HDL C ratio is a better predicting index for geriatric CHD risk.
