CAS associated with higher recurrence and mortality in AF stroke; leaves open whether screening or intervention improves outcomes.
Does concomitant carotid artery stenosis increase the risk of stroke recurrence and mortality in patients with atrial fibrillation and acute stroke?
Concomitant carotid artery stenosis in patients with atrial fibrillation and acute stroke doubles the risk of stroke recurrence and significantly increases 30-day mortality.
