Key result
Study evaluates long-term outcomes across three distinct AF phenotypes following ischemic stroke.
Why the study?
AF-associated ischemic stroke is often managed as a single clinical entity, but prognosis may vary by detection timing and prior oral anticoagulant use.
Do long-term outcomes after ischemic stroke vary across different atrial fibrillation phenotypes defined by detection timing and prior anticoagulation status?
Observational
Do long-term outcomes after ischemic stroke vary across different atrial fibrillation phenotypes defined by detection timing and prior anticoagulation status?
Post-stroke outcomes may differ by AF phenotype; leaves open whether detection timing or prior OAC status should guide therapy.
Atrial fibrillation (AF)–associated ischemic stroke is often managed as a single clinical entity; however, prognosis may vary depending on whether AF was detected after the stroke or whether the stroke occurred despite prior oral anticoagulant (OAC) use. We aimed to describe long-term outcomes after ischemic stroke across 3 distinct AF phenotypes: AF complicated by ischemic stroke despite prior anticoagulation (AFIDA), AF complicated by ischemic stroke without prior anticoagulation (OAC-naive AF), and AF detected after stroke (AFDAS).

Egashira et al. (2026) conducted an observational in Atrial fibrillation-associated ischemic stroke. Atrial fibrillation phenotypes (AFIDA, OAC-naive AF, AFDAS) was evaluated on Long-term outcomes. The study aimed to describe long-term outcomes across three distinct atrial fibrillation phenotypes, but no results were reported in the abstract.
