Even light activity may lower risk of stroke and death in people with atrial fibrillation

A new study published in the Journal of the American Heart Association reveals that physical activity may lower the risk of stroke and death for individuals with atrial fibrillation, or AFib. Atrial fibrillation, a condition characterized by irregular heartbeats in the heart's upper chambers, can lead to blood clots, stroke, and other heart-related complications.

Although people with AFib tend to be less active than the general population, the research indicates that regular physical activity, even at low levels, is associated with a reduced risk of stroke and death for both those with and without AFib.

The study, which followed over 87,000 adults in Norway for approximately 15 years, tracked AFib, stroke, and mortality data from national health registries. The findings suggest that higher self-reported physical activity was linked to a 9-19% lower risk of stroke and an 11-22% lower risk of all-cause mortality. Interestingly, among individuals with AFib, the association with physical activity corresponded to an additional 0.5-1.2 years of life.

Experts emphasize that the study adds valuable evidence to the potential benefits of physical activity for people with AFib and the general population. It highlights that even lower levels of activity are associated with benefits, and moderate to high levels of exercise are linked to greater advantages. Clinicians and patients are encouraged to prioritize regular physical activity as a preventive strategy for stroke and death, as every bit of exercise is better than none.
