Overview

AF associated with higher early mortality after first stroke; leaves open whether it increases recurrent stroke risk over sinus rhythm.

Structured PICO

Population

Atrial fibrillation

Outcome
Prevalence of atrial fibrillation by type of stroke; effect of atrial fibrillation on case fatality rate and risk of recurrent stroke, vascular death, and death from all causeshard clinical

In patients with first-ever stroke, atrial fibrillation is associated with higher early mortality but not a definite excess risk of recurrent stroke compared to sinus rhythm.
