Norwegian trials link structured exercise and activity levels to reduced atrial fibrillation burden and stroke risk
Two major studies presented in August 2026 highlight the benefits of physical activity for patients with atrial fibrillation (AF). The NEXAF trial, presented at the ESC Congress, found that a one-year hybrid exercise program reduced AF burden by 45% and AF-related hospitalizations by 46%. Concurrently, a large observational study in the Journal of the American Heart Association linked higher physical activity to up to 22% lower mortality and 19% lower stroke risk in AF patients, extending life expectancy by up to 1.15 years. Despite these findings, implementation remains low, with only 10% of eligible patients receiving exercise rehabilitation.
