Abstract

Introduction: Data is limited on the safety of early initiation of direct oral anticoagulation (DOAC) treatment after acute ischemic stroke (AIS) receiving reperfusion therapy in patients with atrial fibrillation (AF). We investigated the timing of DOAC initiation and its association with safety and outcomes.

Materials and methods: We included AIS patients receiving reperfusion therapy with AF diagnosis (prevalent or new) registered in the Safe Implementation of Treatments in Stroke international registry during 2013-2024. Safety outcomes were hemorrhage and death. Secondary outcomes were recurrent AIS, any embolism and functional independence (modified Rankin Scale [mRS] 0-2) at 3 months. We performed descriptive statistics and multivariable analysis for DOAC initiation time as an ordinal variable (0-3, 4-7, and 8-100 days after stroke onset) and its association with outcomes. Explorative analyses were performed to investigate factors associated with DOAC initiation time, as a continuous or ordinal variable.

Results: In total, 13,389 patients had data on DOAC initiation time, and 7861 patients had new event data by 3-month follow-up. We observed 0.1% intracranial hemorrhage, 0.4% major extracranial hemorrhage, 1.1% recurrent ischemic stroke, and 0.2% systemic embolism. At 3 months, 4.8% patients had died, and functional independence was seen in 60.9%. In multivariable analyses, DOAC initiation after stroke onset was not associated with any outcomes. Higher 24 h NIHSS and lower pre-stroke mRS score were associated with delayed DOAC initiation.

Conclusion: DOAC initiation time was not associated with any outcomes in AIS patients who received reperfusion therapy. Severe stroke symptoms at 24 h were associated with delayed DOAC initiation. The low incidence of safety outcomes and missing data in this study should lead to cautious interpretations of these results.

期刊介绍： Launched in 2016 the European Stroke Journal (ESJ) is the official journal of the European Stroke Organisation (ESO), a professional non-profit organization with over 1,400 individual members, and affiliations to numerous related national and international societies. ESJ covers clinical stroke research from all fields, including clinical trials, epidemiology, primary and secondary prevention, diagnosis, acute and post-acute management, guidelines, translation of experimental findings into clinical practice, rehabilitation, organisation of stroke care, and societal impact. It is open to authors from all relevant medical and health professions. Article types include review articles, original research, protocols, guidelines, editorials and letters to the Editor. Through ESJ, authors and researchers have gained a new platform for the rapid and professional publication of peer reviewed scientific material of the highest standards; publication in ESJ is highly competitive. The journal and its editorial team has developed excellent cooperation with sister organisations such as the World Stroke Organisation and the International Journal of Stroke, and the American Heart Organization/American Stroke Association and the journal Stroke. ESJ is fully peer-reviewed and is a member of the Committee on Publication Ethics (COPE). Issues are published 4 times a year (March, June, September and December) and articles are published OnlineFirst prior to issue publication.
