Nonvitamin K-dependent oral anticoagulant agents (NOACs) are currently recommended for patients with atrial fibrillation at risk for stroke. As a group, NOACs significantly reduce stroke, intracranial hemorrhage, and mortality, with lower to similar major bleeding rates compared with warfarin. All NOACs are dependent on the kidney for elimination, such that patients with creatinine clearance <25 ml/min were excluded from all the pivotal phase 3 NOAC trials. It therefore remains unclear how or if NOACs should be prescribed to patients with advanced chronic kidney disease and those on dialysis. The authors review the current pharmacokinetic, observational, and prospective data on NOACs in patients with advanced chronic kidney disease (creatinine clearance <30 ml/min) and those on dialysis. The authors frame the evidence in terms of risk versus benefit to bring greater clarity to NOAC-related major bleeding and efficacy at preventing stroke specifically in patients with creatinine clearance <30 ml/min.
非维生素 K 依赖性口服抗凝剂(NOACs)目前推荐用于有中风风险的房颤患者。作为一个整体,NOACs 可显著降低中风、颅内出血和死亡率,与华法林相比,大出血发生率较低或相似。所有的 NOACs 都依赖于肾脏来清除,因此所有关键性的 3 期 NOAC 试验都排除了肌酐清除率<25ml/min 的患者。因此,对于晚期慢性肾脏病和透析患者,NOACs 应该如何或是否应该开处方仍然不清楚。作者回顾了目前关于晚期慢性肾脏病(肌酐清除率<30ml/min)和透析患者的 NOACs 的药代动力学、观察性和前瞻性数据。作者根据风险与获益来阐述证据,以更清楚地了解 NOAC 相关的大出血和预防中风的疗效,特别是在肌酐清除率<30ml/min 的患者中。
