Stroke prevention is the cornerstone of management of atrial fibrillation (AF), and non-vitamin K antagonist oral anticoagulants (NOACs) are commonly prescribed. Because routine monitoring of anticoagulant effects of NOACs is not necessary, appropriate dosing following the criteria of each NOACs defined in pivotal randomized trials is important. Real-world data demonstrate that underdosing NOACs is associated with a higher risk of ischemic stroke without a lower risk of major bleeding. Furthermore, renal function of AF patients should be assessed using the Cockcroft-Gault formula to prevent overestimation that could result in overdosing of NOACs. The assessment of bleeding risk is important, and the HAS-BLED score should be used to help identify patients at high risk of bleeding (HAS-BLED score ≥3). Moreover, the HAS-BLED score should be reassessed at periodic intervals to address potentially modifiable bleeding risk factors because bleeding risks of AF patients are not static. When managing NOAC-related bleeding episodes, the possibility of occult malignancies (e.g., grastrointestinal [GI] tract cancers for patients experiencing GI bleeding and bladder cancer for patients with hematuria) should be kept in mind. Addressing all of these issues is crucial to achieving better clinical outcomes for anticoagulated AF patients. More efforts are necessary to incorporate clear and easy-to-follow recommendations about optimal management of anticoagulation into the guidelines to improve AF patient care.

亚洲房颤患者抗凝治疗的优化管理

中风预防是心房颤动 (AF) 管理的基石,通常开具非维生素 K 拮抗剂口服抗凝剂 (NOAC)。由于不需要对 NOAC 的抗凝作用进行常规监测,因此按照关键随机试验中定义的每种 NOAC 的标准进行适当的给药是很重要的。真实世界的数据表明,NOAC 剂量不足与缺血性卒中风险较高相关,而大出血风险较低。此外,应使用 Cockcroft-Gault 公式评估 AF 患者的肾功能,以防止可能导致 NOAC 过量的高估。出血风险的评估很重要,应使用 HAS-BLED 评分来帮助识别出血风险高的患者(HAS-BLED 评分≥3)。而且,HAS-BLED 评分应定期重新评估,以解决潜在可改变的出血风险因素,因为 AF 患者的出血风险不是静态的。在处理 NOAC 相关出血事件时,应牢记隐匿性恶性肿瘤的可能性(例如,胃肠道出血患者为胃肠道癌,血尿患者为膀胱癌)。解决所有这些问题对于为抗凝 AF 患者实现更好的临床结果至关重要。需要做出更多努力,将关于最佳抗凝治疗的明确且易于遵循的建议纳入指南,以改善 AF 患者的护理。在处理 NOAC 相关出血事件时,应牢记隐匿性恶性肿瘤的可能性(例如,胃肠道出血患者为胃肠道癌,血尿患者为膀胱癌)。解决所有这些问题对于为抗凝 AF 患者实现更好的临床结果至关重要。需要做出更多努力,将关于最佳抗凝治疗的明确且易于遵循的建议纳入指南,以改善 AF 患者的护理。在处理 NOAC 相关出血事件时,应牢记隐匿性恶性肿瘤的可能性(例如,胃肠道出血患者为胃肠道癌,血尿患者为膀胱癌)。解决所有这些问题对于为抗凝 AF 患者实现更好的临床结果至关重要。需要做出更多努力,将关于最佳抗凝治疗的明确且易于遵循的建议纳入指南,以改善 AF 患者的护理。
