Long-Term Incidence of Atrial Fibrillation and Stroke Among Cross-Country Skiers
Why the study?
Does cross-country skiing alter the long-term incidence of atrial fibrillation and stroke compared to nonskiers?
Population
Female and male cross-country skiers in Vasaloppet and nonskiers
Comparison
Vasaloppet skiers vs nonskiers

Implication
Skiing was associated with lower post-AF stroke and death; hypothesis-generating for endurance exercise effects and requires prospective confirmation.
Structured PICO
Does cross-country skiing alter the long-term incidence of atrial fibrillation and stroke compared to nonskiers?
P
Population
Cross-country skiers (Vasaloppet participants) and nonskiers
I
Intervention
Cross-country skiing (participation in Vasaloppet races)
C
Comparator
Nonskiers
O
Outcome
Incidence of atrial fibrillation and strokehard clinical
Despite a potential increased risk of atrial fibrillation in high-performing male athletes, cross-country skiers have a lower overall risk of stroke and death even after an atrial fibrillation diagnosis, indicating that exercise should not be avoided.
