Prediction of Incident Atrial Fibrillation According to Gender in Patients With Ischemic Stroke From a Nationwide Cohort

The CHA2DS2-VASc score may identify patients at higher risk of atrial fibrillation (AF) following ischemic stroke (IS) in patients without known AF. We compared gender-related differences in items from CHA2DS2-VASc score and their relation with AF occurrence after IS. This French cohort study was based on the database covering hospital care from 2009 to 2012 for the entire population. Of 336,291 patients with IS, 240,459 (71.5%) had no AF at baseline. Women were older, more frequently had hypertension, heart failure, and had a higher CHA2DS2-VASc score than men (4.63 vs 4.39, p
