EHJ:临床大发现:降脂还只知道LDL-C?残余胆固醇才是“罪魁祸首”!

2021-09-26 MedSci原创 MedSci原创

无论LDL-C水平如何,残余胆固醇(RC)水平≥24 mg/dL,动脉粥样硬化相关性疾病的发生风险升高

根据既往认知,大家都已认定血液中的胆固醇和甘油三酯是血脂管理的重中之重,同时可以预测血管事件(CVD)的发生风险。其中,高密度脂蛋白(HDL)和低密度脂蛋白(LDL)是胆固醇中的一对“死对头”——LDL将脂质带到外周组织中,HDL更多是对胆固醇的反向转运,也就是不断将胆固醇从外周组织运输到肝脏。因此,LDL-胆固醇(LDL-C)一直被认为是“坏胆固醇”。

然而,最近发表在《美国心脏病学会杂志》(JACC)上的两项大型研究则激起了大家上述认知的争议:残余胆固醇,而非LDL-C或许才是引起ASCVD的罪魁祸首。残余胆固醇(Remnant-C)被定义为除了LDL-C和HDL-C外,人体内包括VLDL-C与中密度脂蛋白胆固醇(IDL-C)等两种胆固醇的含量。

近期来自美国约翰霍普金斯的专家发表在在《欧洲心脏病杂志》EHJ上的研究更近一步揭示了残余胆固醇对心血管疾病的预测价值。无论LDL-C水平如何,残余胆固醇水平≥24 mg/dL,动脉粥样硬化相关性疾病的发生风险升高。

研究人员汇集了来自社区动脉硬化风险研究(n = 9748)、动脉硬化多种族研究(n = 3049)和年轻人冠状动脉风险发展(n = 4735)的17532名冠心病(ASCVD)的人的数据。将非高密度脂蛋白胆固醇(非HDL-C)减去LDL-C计算得残余胆固醇(RC)。调整后的Cox模型被用来估计与对数RC水平相关的发生ASCVD的风险。此外还进行了不一致分析,利用百分位数单位(>10个单位)和临床相关的LDL-C目标的差异,检查RC与LDL-C不一致/一致组的相对ASCVD风险。

参与者的平均年龄为52.3±17.9岁,56.7%为女性,34%为黑人。在18.7年的中位随访期间,共有2143例ASCVD事件。经过包括LDL-C和apoB在内的多变量调整,对数RC与ASCVD风险增加65%有关[危险比(HR)1.65,95%置信区间(CI)1.45-1.89]。此外,与RC与LDL-C均升高的组相比,高RC/低LDL-C组,而不是低RC/高LDL-C组,与ASCVD风险增加21%有关(HR =1.21,95% CI 1.08-1.34)。在检查不同临床切点的不一致时,也显示了类似的结果。

无论LDL-C水平如何,RC≥24 mg/dL,动脉粥样硬化相关性疾病的发生风险升高

综上,残余胆固醇或可作为冠心病或中风发生风险的独立预测因子。此外,残余胆固醇检测结果或将有助于判断LDL水平无法反映的潜在心血管疾病。
