NEJM:急性冠状动脉综合征患者替卡格雷或普拉格雷疗效比较

2019-10-17 xing.T MedSci原创

由此可见,在所有伴有或不伴有ST段抬高的急性冠脉综合征患者中,接受普拉格雷治疗的患者的死亡、心肌梗塞或卒中的发生率均显著低于接受替卡格雷的患者,并且发生大出血的患者两组之间无显著差异。

在计划进行有创性评估的急性冠状动脉综合征患者中,替卡格雷与普拉格雷的相对优势尚不确定。

近日,顶级医学期刊NEJM上发表了一篇研究文章,在这项多中心、随机、开放标签试验中,研究人员随机分配了急性冠脉综合征并进行有创性评估的患者接受替卡格雷或普拉格雷治疗。该研究的主要终点是1年时死亡、心肌梗塞或卒中的综合事件。该研究的主要次要终点(安全终点)是出血。

该研究共有4018例患者接受了随机分组。替格瑞洛组2012名患者中有184名患者(9.3%)和普拉格雷组2006名患者中有137名患者(6.9%)发生了主要终点事件(风险比为1.36;95%置信区间[CI]为1.09至1.70;P=0.006)。替卡格雷组和普拉格雷组各主要终点单个发生率分别为:死亡,分别为4.5%和3.7%;心肌梗塞,分别为4.8%和3.0%;卒中,分别为1.1%和1.0%。替格瑞洛组的患者中有1.3%发生了明确或可能的支架内血栓,普拉格雷组中有1.0%的患者发生了支架内血栓,明确支架内血栓的发生率分别为1.1%和0.6%。替卡格雷组有5.4%的患者和普拉格雷组患者中有4.8%的患者发生严重出血(根据出血学术研究联合会的定义)(风险比为1.12;95%CI为0.83至1.51; P=0.46)。

由此可见,在所有伴有或不伴有ST段抬高的急性冠脉综合征患者中,接受普拉格雷治疗的患者的死亡、心肌梗塞或卒中的发生率均显著低于接受替卡格雷的患者,并且发生大出血的患者两组之间无显著差异。
