JAHA:二十碳五烯乙酯治疗以减少既往经皮冠状动脉介入治疗患者的缺血事件

2022-03-12 MedSci原创 MedSci原创

在接受他汀类药物治疗且既往有PCI病史的甘油三酯升高患者中,平均约5年的随访期间,二十碳五烯酸乙酯治疗显著降低了复发事件的风险,其中仅需要治疗12年。

尽管进行了积极的药物治疗,但接受经皮冠状动脉介入治疗(PCI)的患者发生血管事件的风险增加。

近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员对REDUCE-IT(使用二十碳五烯酸乙脂-干预试验减少心血管事件)研究进行了事后分析,该研究是一项比较二十碳五烯酸乙酯与安慰剂的多中心、随机、双盲、安慰剂对照试验。在低密度脂蛋白胆固醇<100mg/dL和空腹甘油三酯135-499mg/dL的患者中,研究人员在受试者他汀类药物治疗方案中加入了二十碳五烯乙酯。

该研究的主要终点是心血管死亡、非致死性心肌梗死、非致死性卒中、冠状动脉血运重建或需要住院治疗的不稳定型心绞痛的复合结局。

8179名患者被随机分组,中位随访时间为4.9年,其中3408名(41.7%)患者接受过PCI,中位随访时间为4.8年。这些患者在PCI后被随机分配中位时间为2.9年(11天至30.7年)。在接受二十碳五烯酸乙酯与安慰剂治疗的患者中,主要复合终点降低了34%(风险比[HR]为0.66;95%CI为0.58-0.76;P<0.001;需要治疗的人数4.8年=12)和心血管死亡、非致死性心肌梗死或非致死性卒中的关键次要复合终点降低34%(HR为0.66;95%CI为0.56-0.79;P<0.001;NNT4.8年=19)。同样,总冠状动脉血运重建和血运重建亚型也大幅减少。总事件也减少了39%(比率为0.61;95%CI为0.52-0.72;P<0.001)。

由此可见,在接受他汀类药物治疗且既往有PCI病史的甘油三酯升高患者中,平均约5年的随访期间,二十碳五烯酸乙酯治疗显著降低了复发事件的风险,其中仅需要治疗12年。
