JAMA Inter Med:缺血性心脏病患者的治疗,LDL胆固醇的水平越低越好?

据来自Clalit 研究所的新的一项回顾性队列研究表明,使用他汀适度降低低密度脂蛋白(LDL) 胆固醇降低缺血性心脏病患者不良结局的效果与强化降脂的效果一样,该研究结果已发表于JAMA Internal Medicine。

研究人员探究了缺血性心脏病患者经他汀治疗后不同LDL 胆固醇的水平与主要不良心脏事件发生风险之间的关系。该研究对比了他汀治疗1年后低水平LDL 胆固醇(≤70 mg/dL)与中等水平(70.1~100 mg/dl)及高水平LDL 胆固醇(100.1~130 mg/dl)的效果。


研究共纳入了31619名缺血性心脏病患者接受他汀治疗,服药依从性≥80%。29%的患者为低水平LDL胆固醇,53%的患者为LDL胆固醇,18%的患者为高水平LDL胆固醇。平均随访1.6年,在此期间共有9035名患者发生重大心脏事件或死亡。

结果显示,低水平LDL胆固醇组患者与中等水平LDL胆固醇组患者重大心脏事件发生或死亡的风险并无差异。但是与高水平LDL胆固醇组患者相比,中等水平LDL胆固醇组患者重大心脏事件的发生率低11%。

非线性建模表明,达到较低的LDL胆固醇水平与心血管事件发生风险降低有关,但是仅是90 mg/dL左右。

该研究领导者 Morton Leibowitz总结道,“我们的研究结果并不认为所有患者的二级预防时更低的LDL胆固醇水平更有利于其健康。”但是,同时研究人员还指出该研究存在一些局限性,包括回顾性数据的使用,以及使用他汀类药物治疗至少1年后LDL胆固醇水平的分类,而实际上LDL胆固醇的水平会随着时间的变化而变化。

在一篇伴随社论中,来自加利福尼亚大学旧金山医学院的Simon Ascher,Blake Charlton及Rita Redberg指出“这项回顾性研究在确定长期他汀类药物治疗的目标上做出了重大努力。”该研究结果或可有助于减少为达到更低目标LDL胆固醇水平而使用高剂量他汀类药物治疗的不利影响,而最大化有利影响。。
