近日,血管领域权威杂志Arteriosclerosis, Thrombosis, and Vascular Biology上发表了一篇研究文章,这项研究旨在全面评估多种脂质指标与外周动脉疾病(PAD)之间的关联。

研究人员使用Cox比例风险模型来归纳每种空腹血脂指标(总胆固醇、低密度脂蛋白胆固醇[LDL-C]、高密度脂蛋白胆固醇[HDL-C]、甘油三酸酯、残余脂蛋白胆固醇[RLP-C]、LDL-甘油三酸酯[LDL-TG]、小而密LDL-C[sdLDL-C]和含Apo-E的HDL-C[Apo-E-HDL])与通过国际疾病分类(第九版,临床修改(ICD-9-CM))出院代码(例如440.2)确定的PAD发病率之间相关性,该研究的参与者为在基线(1996-1998年)至2015年间无PAD的8330名黑人和白人(平均年龄为62.8 [SD为5.6]岁)。由于脂质性状彼此存在生物学相关性,因此,研究人员也进行了主成分分析以确定潜在PAD风险的成分。

平均随访17年期间,共发生246次PAD事件。在考虑了潜在的混杂因素之后,以下脂质指标与PAD显着相关(每升高1个SD的风险比[HDL-C和Apo-E-HDL为降低]):甘油三酯为1.21(95%CI为1.08-1.36);RLP-C为1.18(1.08–1.29);LDL-TG为1.18(1.05-1.33);HDL-C为1.39(1.16-1.67)和Apo-E-HDL为1.27(1.07-1.51)。主成分分析确定了3个成分(1:甘油三酯、RLP-C、LDL-TG和sdLDL-C; 2:HDL-C和Apo-E-HDL; 3:LDL-C和RLP-C)。成分1和2显示与PAD事件独立相关。

由此可见,甘油三酯和HDL相关的脂质与PAD事件独立相关,这对PAD的预防策略具有重要意义。但是,没有一种新的脂质指标优于常规指标
