Patients With Ischemic Stroke and Incident Atrial Fibrillation
Key result
Ischemic stroke was associated with an incident atrial fibrillation rate of 7.9 per 100 person-years, compared to 5.9% in patients with a cardiac hospitalization.
Population
48,992 patients with ischemic stroke without prior diagnosed atrial fibrillation.

Implication
Supports post-stroke AF monitoring in high-CHADS2 patients; leaves open whether screening improves outcomes.

Population
48,992 patients with ischemic stroke without prior diagnosed atrial fibrillation from a French national database, followed for a mean of 15 months.

Comparator
826,416 patients with a cardiac hospitalization

Outcome

Main Result
Absolute Event Rate: 7.9% vs 5.9%
Patients with ischemic stroke have a high rate of incident atrial fibrillation, which can be predicted using standard CHADS2 and CHA2DS2-VASc scores.
Cite This Study
Fauchier et al. (2015) conducted a cohort in Ischemic stroke without prior diagnosed atrial fibrillation (n=48,992). Ischemic stroke vs. Cardiac hospitalization was evaluated on Incident atrial fibrillation. Ischemic stroke was associated with an incident atrial fibrillation rate of 7.9 per 100 person-years, compared to 5.9% in patients with a cardiac hospitalization.
