JAHA:多少房颤患者在大出血后不再抗凝?

2018-08-09 吴星 环球医学

2018年6月,美国学者在《J Am Heart Assoc》发表了ORBIT-AF结果,考察了房颤患者中,大出血、临床相关非大出血和滋扰性出血后的治疗策略。

2018年6月,美国学者在《J Am Heart Assoc》发表了ORBIT-AF结果,考察了房颤患者中,大出血、临床相关非大出血和滋扰性出血后的治疗策略。

背景:口服抗凝药(OAC)可降低房颤患者卒中风险,但是出血是常见的副作用。因出血事件而决定停止或修改用药方案,根据出血部位和严重程度的不同而具有差异。

方法和结果:研究者使用一个大型全国门诊患者注册ORBIT-AF(房颤更明智治疗的结局;2010~2011)的数据,评估事件特征和随访期首次出血事件后的OAC管理。出血事件分为3类:(1)国际血栓和止血学会定义的大出血、(2)需要医疗关注的临床相关非大出血和(3)不需要医疗关注的滋扰性出血(如瘀伤、痔疮出血)。9743名纳入到ORBIT-AF且有随访数据的患者中,两年首次出血的类型分别为:510人(3.23/100人-年)出现大出血,615人(3.90/100人-年)临床相关非大出血,1558人(9.87/100人-年)出现滋扰性出血。约1/3的患者(31.6%)大出血事件后停止OAC治疗,12.7%的患者在临床相关非大出血后停用,4.5%的患者在滋扰性出血后停用。与临床相关非大出血或滋扰性出血相比,大出血患者更可能为黑人和女性,并具有心衰史和卒中史。停用OAC的患者比继续OAC治疗的患者更可能具有中枢神经系统症状或IBD%E8%AF%8A%E6%B2%BB%E8%BF%87%E7%A8%8B%E4%B8%AD%E7%9A%84%E8%AF%84%E4%BC%B0-Part%203" target="_blank">胃肠道出血。

结论:总体来说,1/3出现大出血的患者在事件后不再抗凝。停用OAC的患者比继续OAC的患者更可能具有中枢神经系统症状或IBD%E8%AF%8A%E6%B2%BB%E8%BF%87%E7%A8%8B%E4%B8%AD%E7%9A%84%E8%AF%84%E4%BC%B0-Part%203" target="_blank">胃肠道出血。
