BMJ:房颤患者使用达比加群和华法林的出血率和血栓发生率

2016-05-24 MedSci MedSci原创

目的该研究的目的是通过随机对照实验研究探究患者常规服用华法林或达比加群后出现血栓栓塞和出血的发生率,并预测模型相应的事件发生率并进行对照。 方法该研究为队列研究,数据信息来自美国健康研究(2009年10月-2013年6月),这是美国的一个商业医疗数据库。参与者共有21934名成年人,他们患有房颤,常规服用达比加群(150mg)或华法林治疗。主要结果研究人员关注的主要结果是患者出现血栓或出血的发生率

目的
该研究的目的是通过随机对照实验研究探究患者常规服用华法林或达比加群后出现血栓栓塞和出血的发生率,并预测模型相应的事件发生率并进行对照。
方法
该研究为队列研究,数据信息来自美国健康研究(2009年10月-2013年6月),这是美国的一个商业医疗数据库。参与者共有21934名成年人,他们患有房颤,常规服用达比加群(150mg)或华法林治疗。
主要结果
研究人员关注的主要结果是患者出现血栓或出血的发生率,基于随机对照实验,设计出常规服用抗凝剂和有基础风险评分(CHADS2、CHA2DS2-VASc和HAS-BLED)的模型。血栓是一个综合的主要结果,包括缺血性卒中、短暂性脑缺血发作、肺栓塞、深静脉血栓形成和系统性栓塞等多种表现形式。出血也包括多种形式如出血性卒中、原因未明的胃肠出血和其他泌尿生殖系统出血。
结果
共有6516名患者(30%)服用达比加群,15418名患者(70%)服用华法林。发生血栓栓塞的几率为1.7/100名患者/年,发生出血的发生率为4.6/100名患者/年。就血栓栓塞发生率而言,实验结果与模型预测结果相似;然而,模型结果计算出的患者出血率数值偏低,服用华法林药物且HAS-BLED得分较高的患者尤为明显,事件发生率较真实数据偏低4/100名患者/年。随机对照实验得出患者服用达比加群和华法林出现血栓栓塞和出血的一致性指数范围为0.59-0.66,模型预测发生率一致性指数介于0.52-0.70。
结论
研究人员指出,我们低估了服用达比加群和华法林的患者的出血发生率,因此日常生活中需要密切关注患者的出凝血常规等检查结果,必要时采取替代治疗方案。
