Data on non-vitamin K antagonist oral anticoagulants (NOACs) use in patients with atrial fibrillation (AF) and frailty are scarce. Therefore, the impact of frailty on AF-related outcomes and benefit-risk profiles of NOACs in patients with frailty were investigated.
AF patients initiating anticoagulation between 2013 and 2019 were included using Belgian nationwide data. Frailty was assessed with the Claims-based Frailty Indicator. Among 254 478 anticoagulated AF patients, 71 638 (28.2%) had frailty. Frailty was associated with higher all-cause mortality risks [adjusted hazard ratio (aHR) 1.48, 95% confidence interval (CI) (1.43-1.54)], but not with thromboembolism or bleeding. Among subjects with frailty (78 080 person-years of follow-up), NOACs were associated with lower risks of stroke or systemic embolism (stroke/SE) [aHR 0.77, 95%CI (0.70-0.86)], all-cause mortality [aHR 0.88, 95%CI (0.84-0.92)], and intracranial bleeding [aHR 0.78, 95%CI (0.66-0.91)], a similar major bleeding risk [aHR 1.01, 95%CI (0.93-1.09)], and higher gastrointestinal bleeding risk [aHR 1.19, 95%CI (1.06-1.33)] compared with VKAs. Major bleeding risks were lower with apixaban [aHR 0.84, 95%CI (0.76-0.93)], similar with edoxaban [aHR 0.91, 95%CI (0.73-1.14)], and higher with dabigatran [aHR 1.16, 95%CI (1.03-1.30)] and rivaroxaban [aHR 1.11, 95%CI (1.02-1.21)] compared with VKAs. Apixaban was associated with lower major bleeding risks compared with dabigatran [aHR 0.72, 95%CI (0.65-0.80)], rivaroxaban [aHR 0.78, 95%CI (0.72-0.84)] and edoxaban [aHR 0.74, 95%CI (0.65-0.84)], but mortality risk was higher compared with dabigatran and edoxaban.
Frailty was an independent risk factor of death. Non-vitamin K antagonist oral anticoagulants had better benefit-risk profiles than VKAs in patients with frailty, especially apixaban, followed by edoxaban.
关于房颤(AF)和虚弱患者使用非维生素 K 拮抗剂口服抗凝剂(NOACs)的数据很少。因此,研究了虚弱对 AF 相关结局和 NOACs 在虚弱患者中的获益-风险特征的影响。
使用比利时全国性数据纳入了 2013 年至 2019 年期间开始抗凝治疗的 AF 患者。使用基于索赔的虚弱指标评估虚弱。在 254478 例接受抗凝治疗的 AF 患者中,71638 例(28.2%)有虚弱。虚弱与全因死亡率风险增加相关[校正后的危险比(aHR)1.48,95%置信区间(CI)(1.43-1.54)],但与血栓栓塞或出血无关。在虚弱患者(78080 人年随访)中,NOACs 与卒中或全身性栓塞(卒中/SE)[aHR 0.77,95%CI(0.70-0.86)]、全因死亡率[aHR 0.88,95%CI(0.84-0.92)]和颅内出血[aHR 0.78,95%CI(0.66-0.91)]的风险降低相关,大出血风险相似[aHR 1.01,95%CI(0.93-1.09)],胃肠道出血风险更高[aHR 1.19,95%CI(1.06-1.33)]与 VKAs 相比。与 VKAs 相比,阿哌沙班的大出血风险较低[aHR 0.84,95%CI(0.76-0.93)],依度沙班相似[aHR 0.91,95%CI(0.73-1.14)],达比加群和利伐沙班较高[aHR 1.16,95%CI(1.03-1.30)]和[aHR 1.11,95%CI(1.02-1.21)]。与 VKAs 相比,阿哌沙班与较低的大出血风险相关[aHR 0.72,95%CI(0.65-0.80)],利伐沙班[aHR 0.78,95%CI(0.72-0.84)]和依度沙班[aHR 0.74,95%CI(0.65-0.84)],但与达比加群和依度沙班相比,死亡率风险更高。
虚弱是死亡的独立危险因素。与 VKAs 相比,非维生素 K 拮抗剂口服抗凝剂在虚弱患者中有更好的获益-风险特征,尤其是阿哌沙班,其次是依度沙班。
