Does Atrial Fibrillation Detected After Stroke (AFDAS) carry a different risk of recurrent stroke, mortality, and intracerebral hemorrhage compared to Known Atrial Fibrillation (KAF)?
Patients with atrial fibrillation detected after a stroke (AFDAS) may have a lower risk of recurrent ischemic stroke and mortality compared to those with previously known atrial fibrillation.
AFDAS may carry a lower risk of ischemic stroke recurrence and mortality compared with KAF, with similar risk of intracerebral hemorrhage. Stratification through implementation of AF burden measures may support more personalized management for people with AFDAS.
Romoli et al. (2025) studied this question.
