JACC:房颤患者使用达比加群2年内依从性如何?

2017-10-10 王立群 环球医学

2017年9月,发表在《J Am Coll Cardiol》上的一项研究,调查了房颤患者在2年的随访期中对达比加群酯依从性。研究结果显示:2年后,达比加群治疗依从的概率约为70%。近一半停用达比加群的患者转换为另一种口服抗凝药。并且北美患者和具有阵发性、持续性或症状性房颤的患者具有较高的停止达比加群风险。

2017年9月,发表在《J Am Coll Cardiol》上的一项研究,调查了房颤患者在2年的随访期中对达比加群酯依从性。研究结果显示:2年后,达比加群治疗依从的概率约为70%。近一半停用达比加群的患者转换为另一种口服抗凝药。并且北美患者和具有阵发性、持续性或症状性房颤的患者具有较高的停止达比加群风险。

背景:指南建议,房颤患者须长期口服抗凝治疗进行卒中预防。维生素K拮抗剂(VKA)治疗的患者中,停药率较高,但是非VKA口服抗凝药治疗的患者的停药率可能较低。

目的:旨在描述和探讨新确诊为房颤的患者在2年的随访期对达比加群酯依从性的预测因素。

方法:新确诊为房颤且具有≥1种卒中风险因素的连续患者随访了2年。达比加群非依从性的定义为,达比加群停药>30天。多变量Cox回归模型纳入了地区以及患者临床和社会经济特征,从而探讨非依从性的预测因素。

结果:符合条件的患者(2932例)服用了≥1次达比加群给药,平均70.3±10.2岁,55.3%为男性。2年的达比加群依从性概率为69.2%。约7%的患者转换为八因子抑制剂,6%转换为VKA。约三分之一的达比加群停药主要由于严重或非严重不良事件。北美的患者具有最高的停药风险,拉丁美洲的风险最低。症状轻微或无症状性房颤和永久性房颤与较低的达比加群非依从性风险相关。既往质子泵抑制剂使用与较高的达比加群非依从性风险相关。

结论:2年后,达比加群治疗依从的概率约为70%。近一半停用达比加群的患者转换为另一种口服抗凝药。北美患者和具有阵发性、持续性或症状性房颤的患者具有较高的停止达比加群风险。
