JAHA:严重高胆固醇血症的心血管风险和治疗结局

2022-04-27 MedSci原创 MedSci原创

在患有严重高胆固醇血症的个体中,与LDL-C<100mg/dL相关的心血管风险和临床益处逐渐升高。这些结果支持积极降脂,并为该人群的LDL-C目标提供了证据。

经常伴随家族性高胆固醇血症(FH)的严重高胆固醇血症因其全球负担而备受关注。许多学术团体最近都在关注它,以提高对其的认识,并提高及时诊断和治疗;然而,结果仍然不充分。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,该研究旨在使用全国队列评估严重高胆固醇血症患者降脂后的心血管风险和结局。

该研究使用韩国国民健康保险局的数据库。在接受定期健康检查和随访的个体中,该研究共纳入了2377918名参与者,并根据低密度脂蛋白胆固醇(LDL-C)水平分为3个重度高胆固醇血症组,即≥260、225-259和190-224mg/dL组和对照组(<160mg/dL)。研究人员比较了复合心血管事件心肌梗死、冠状动脉血运重建和缺血性卒中)和总死亡的风险。

在他汀类药物新使用者中,根据治疗后LDL-C水平进一步分析他汀类药物使用后的结果。LDL-C≥190mg/dL个体的患病率为106人中有1人。各组中复合事件和总死亡率(中位随访时间为6.1年)的调整后风险比分别高达2.4(对数秩P<0.0001)和2.3(对数秩P=0.0002),并且取决于LDL-C水平。在这些组别中,每个事件的风险分别高出4.1、3.8和1.9倍。降脂后复合事件的风险(中位随访时间为6.2年)降低;特别是,治疗后LDL-C<100mg/dL的组别风险最低(风险比为0.56,对数秩P=0.043)。

由此可见,使用大型韩国队列数据证明,在患有严重高胆固醇血症的个体中,与LDL-C<100mg/dL相关的心血管风险和临床益处逐渐升高。这些结果支持积极降脂,并为该人群的LDL-C目标提供了证据。
