JAHA:替卡格雷治疗后大出血相关的因素分析

2021-03-19 MedSci原创 MedSci原创

体重低、贫血和慢性肾脏疾病是替卡格雷治疗后大出血的危险因素。在有出血风险的患者中,早期停用阿司匹林可带来净临床收益。

目前,缺乏与替卡格雷治疗后临床相关出血因素的数据。近日,血管疾病领域权威杂志JAHA上发表了一篇研究文章,研究人员旨在调查接受冠状动脉支架植入术后服用替卡格雷治疗的的急性冠脉综合征患者大出血相关的临床和手术因素。

该研究为一项随机试验,共纳入了2660例患者。研究人员将由心肌梗死溶栓(TIMI)大出血或出血学术研究联合会定义的大出血患者与无大出血的患者进行了比较。

根据多变量和受试者工作特征曲线分析,体重≤65kg、血红蛋白≤12g/dL和估计的肾小球滤过率<60 mL/min/1.73 m2与大出血风险增加相关。

相比之下,3个月阿司匹林加持续替卡格雷治疗(相比于12个月阿司匹林和替卡格雷治疗)与大出血风险降低相关。接受3个月阿司匹林治疗的患者发生净不良临床事件(TIMI大出血以及心、脑血管重大不良事件的复合结局)的风险较低,在伴有任何危险因素的患者中仍然是如此(比值比为0.59;95%CI为0.39-0.90;交互作用P=0.74)。

由此可见,体重低、贫血和慢性肾脏疾病是替卡格雷治疗后大出血的危险因素。在有出血风险的患者中,早期停用阿司匹林可带来净临床收益
