JACC:不管有无心肌梗死病史,DAPT得分均可预测后期风险

2016-05-28 MedSci MedSci原创

该DAPT(双重抗血小板治疗)研究纳入了冠状动脉支架术后的患者。这些患者随机接受持续噻吩并吡啶和阿司匹林12个月后与那些服用安慰剂和阿司匹林的患者相比,缺血性风险降低,但出血的危险性增加。这项研究旨在确定一个决策工具(DAPT得分),看其是否有助于那些经过冠状动脉支架治疗的之前有或没有心肌梗死(MI)的患者确定双重抗血小板治疗时间处方。根据手术之前的MI历史,研究人员对患者进行分类。在随机治疗期间

该DAPT(双重抗血小板治疗)研究纳入了冠状动脉支架术后的患者。这些患者随机接受持续噻吩并吡啶和阿司匹林12个月后与那些服用安慰剂和阿司匹林的患者相比,缺血性风险降低,但出血的危险性增加。

这项研究旨在确定一个决策工具(DAPT得分),看其是否有助于那些经过冠状动脉支架治疗的之前有或没有心肌梗死(MI)的患者确定双重抗血小板治疗时间处方。

根据手术之前的MI历史,研究人员对患者进行分类。在随机治疗期间(12至30个月)缺血事件(MI和/或支架内血栓形成)和出血事件(闭塞冠状动脉使用链激酶和组织型纤溶酶原激活物的全球性研究)风险的差异是根据DAPT评分进行比较的。

之前有或没有MI的患者MI率分别为3.8% vs 2.4%(p=0.01)。不管有无MI史,继续噻吩并吡啶治疗与安慰剂相比,都会降低后期MI事件概率(有MI历史的风险比[HR]:0.46; P<0.001; 无MI的HR:0.60; P=0.003),增加了出血的风险(有MI历史HR:1.86,P=0.01;无MI的HR:1.58,p=0.01)。与使用安慰剂患者相比,DAPT得分≥2与持续使用噻吩并吡啶患者的MI/支架血栓事件率降低有关(有MI历史的患者为2.7% vs 6.0%,P<0.001;无MI为2.6% vs 5.2%,p=0.002),出血率具有可比性。在两组的DAPT得分<2的患者中,继续服用噻吩并吡啶显著增加出血事件,但缺血事件发生率相似。

之前有MI的患者与那些无MI的患者相比,后期发生缺血性事件的风险更大。该DAPT得分改善了持续双重抗血小板治疗的患者益处和害处的预测,超出单纯MI病史的评估。
