Risk of Recurrent Stroke, Mortality, and Intracerebral Hemorrhage in Patients With Atrial Fibrillation Detected Before or After a Stroke.

Background And Objectives: The risk of recurrent ischemic stroke, intracranial hemorrhage, and mortality in people with atrial fibrillation detected after stroke (AFDAS) is still unclear compared with people with known atrial fibrillation (KAF). We systematically reviewed the literature to provide updated estimates for the risk of recurrent stroke, intracerebral hemorrhage, and mortality in AFDAS compared with KAF.

Methods: Our protocol was registered in PROSPERO (CRD42024583064).
