摘要
在ENVISAGE-TAVI房颤试验中,埃多沙班组与维生素K拮抗剂(VKA)组相比,经导管主动脉瓣植入术(TAVI)成功后的房颤(AF)患者中,缺血性卒中(IS)和任何卒中的发生率均较低。本研究旨在对ENVISAGE-TAVI房颤患者进行治疗亚分析,确定与IS相关的风险因素,这些患者接受了≥1个剂量的依多沙班或VKA治疗。比较了有 IS 与无 IS 患者的基线特征。数字变量的比较采用单因素方差分析;分类变量的比较采用费希尔精确检验。逐步 Cox 回归确定了与首次 IS 事件相关的患者特征。在 1377 名患者中,41 人(3.0%)发生过 IS,1336 人(97.0%)没有发生过 IS;两组患者的基线人口统计学和临床特征非常均衡。依多沙班(57.9%)和 VKA(68.2%)的大多数 IS 发生在 TAVI 术后 180 天内。依多沙班的 IS 发生率为每 100 人年 2.0 例,而 VKA 为每 100 人年 2.7 例。与 IS 独立相关的是系统性栓塞事件(SEEs;危险比 [HR],2.96;95% 置信区间 [CI],1.26-7.00;P = 0.01)和 TAVI 前使用 VKA(HR,2.17;95% 置信区间 [CI],1.12-4.20;P = 0.02)。总之,虽然成功进行TAVI后服用依多沙班或VKA的房颤患者IS的总体发生率较低,但有SEEs病史或TAVI前服用VKA的患者在TAVI后发生IS的风险可能较高。
Risk Factors of Ischemic Stroke in Patients With Atrial Fibrillation After Transcatheter Aortic Valve Implantation from the Randomized ENVISAGE-TAVI AF Trial
In patients with prevalent or incident atrial fibrillation (AF) after successful transcatheter aortic valve implantation (TAVI) enrolled in the EdoxabaN Versus standard of care and theIr effectS on clinical outcomes in pAtients havinG undergonE Transcatheter Aortic Valve Implantation - in Atrial Fibrillation (ENVISAGE-TAVI AF) trial, the incidence of ischemic stroke (IS) and any stroke was numerically less in the edoxaban group than in the vitamin K antagonist (VKA) group. The present study aimed to identify risk factors associated with IS in an on-treatment subanalysis in patients from ENVISAGE-TAVI AF who received ≥1 dose of edoxaban or VKA. Baseline patient characteristics were compared in patients with and those without IS. Numerical variables were compared using a 1-way analysis of variance; categorical variables were compared using Fisher's exact test. Stepwise Cox regression determined patient characteristics associated with the first IS event. Of 1,377 patients, 41 (3.0%) experienced an IS, and 1,336 (97.0%) did not; baseline demographics and clinical characteristics were well balanced between groups. Most ISs occurred within 180 days of TAVI for edoxaban (57.9%) and VKA (68.2%). The rate of IS was 2.0/100 person-years for edoxaban versus 2.7/100 person-years for VKA. Independently associated with IS were history of systemic embolic events (hazard ratio 2.96, 95% confidence interval 1.26 to 7.00, p = 0.01) and pre-TAVI use of VKAs (hazard ratio 2.17, 95% confidence interval 1.12 to 4.20, p = 0.02). In conclusion, although the overall incidence of IS was small for patients with AF on edoxaban or VKA after successful TAVI, patients with a history of systemic embolic events or pre-TAVI use of VKAs may be at greater risk of IS after TAVI.
