Conclusions-—This large cohort study supports the hypothesis that patients with a stroke and with prior regular physical activity
have a lower risk of death, while their risk for recurrent stroke is similar to that of nonskiers. The skiers had a higher incidence of
atrial fibrillation, but still no increased risk of recurring stroke. ( J Am Heart Assoc. 2015;4:e002469 doi: 10.1161/

was 0.66 (95% CI 0.56 to 0.78) and for recurrent stroke 0.82 (95% CI 0.70 to 0.96). After adjustment for smoking and
socioeconomic factors, the HR for death was consistent at 0.70 (95% CI 0.56 to 0.87) while the HR for recurrent stroke was not
statistically significant. Outcomes for skiers with atrial fibrillation tended to show a lower risk than for nonskiers.
