Atrial Fibrillation and Acute Ischemic Stroke: Evaluation of the Contemporary 2018 National Inpatient Sample Database.

Background: Atrial fibrillation (AF) in acute ischemic stroke (AIS) is considered a binary entity regardless of AF type. We aim to investigate in-hospital morbidity and mortality among patients with nonparoxysmal AF-related AIS.

Methods: Patients hospitalized for AIS with associated paroxysmal or persistent AF were identified from the 2018 national inpatient sample database.
