Key result
Atrial fibrillation was an independent risk factor for new thromboembolic stroke in older patients, occurring in 46% of patients with AF versus 17% with sinus rhythm (RR 3.3; P<0.0001).
Why the study?
Does atrial fibrillation increase the incidence of new thromboembolic stroke in older patients?

Does atrial fibrillation increase the incidence of new thromboembolic stroke in older patients?
Atrial fibrillation is a strong independent risk factor for new thromboembolic stroke in older patients residing in long-term care facilities.
Answers are grounded in this paper and cite their sources.
May inform stroke risk awareness in frail elderly long-term care residents; leaves open whether anticoagulation improves outcomes in this population.

Aronow et al. (1996) conducted a cohort in Atrial fibrillation and thromboembolic stroke (n=2,101). Atrial fibrillation vs. Sinus rhythm was evaluated on Incidence of new thromboembolic (TE) stroke (RR 3.3, p=<.0001). Atrial fibrillation was an independent risk factor for new thromboembolic stroke in older patients, occurring in 46% of patients with AF versus 17% with sinus rhythm (RR 3.3; P<0.0001).
