NEJM:PCI术后高危患者服用替卡格雷加不加阿司匹林?

2019-11-21 xing.T MedSci原创

由此可见,在接受PCI并完成3个月双重抗血小板治疗的高危患者中,替卡格雷单药治疗的临床相关出血发生率低于替卡格雷和阿司匹林联合治疗组,且无更高的死亡、心肌病梗塞或卒中风险。

在最小限度的双重抗血小板治疗后P2Y12抑制剂单药治疗是减少经皮冠状动脉介入治疗(PCI)后出血风险的新兴方法。近日,顶级医学期刊NEJM上发表了一篇研究文章,在一项双盲试验中,研究人员评估了出血或缺血性事件高风险且接受PCI的患者采用替卡格雷单药治疗与替卡格雷和阿司匹林联合治疗临床相关出血的效果。

在采用替卡格雷和阿司匹林联合治疗3个月后,未发生大出血或局部缺血事件的患者继续服用替卡格雷治疗,并被随机分配接受阿司匹林或安慰剂治疗1年。该研究的主要终点是出血学术研究联合会(BARC)确定的2、3或5型出血。研究人员还使用非劣效性假设(绝对差值为1.6个百分点)评估了由任何原因、非致命性心肌梗塞或非致命性卒中导致的复合死亡终点。

研究人员纳入了9006例患者,其中7119例患者在3个月后进行了随机分组。随机分组至1年之间,随机分组接受替卡格雷和安慰剂治疗的患者的主要终点发生率为4.0%,接受替卡格雷和阿司匹林治疗的患者主要终点发生率为7.1%(风险比为0.56;95%置信区间[CI]为0.45至0.68;P<0.001)。两组之间的风险差异在3型或5型BARC出血中相似(接受替卡格雷和安慰剂治疗的患者发生率为1.0%,接受替卡格雷和阿司匹林治疗的患者为2.0%;风险比为0.49; 95%CI为0.33至0.74)。两组因任何原因、非致命性心肌梗塞或非致命性卒中死亡的发生率均为3.9%(差异为-0.06%; 95%CI为-0.97至0.84;风险比为0.99;95%CI为0.78至1.25,非劣性P<0.001)。

由此可见,在接受PCI并完成3个月双重抗血小板治疗的高危患者中,替卡格雷单药治疗的临床相关出血发生率低于替卡格雷和阿司匹林联合治疗组,且无更高的死亡、心肌病梗塞或卒中风险。
