Key result
Exercise testing and training unmask subclinical dysfunction and improve arrhythmia burden and atrial remodeling in AF.
Exercise testing and training are proposed as key components in managing atrial fibrillation by unmasking comorbidities and improving arrhythmia burden.
May support exercise testing in AF evaluation; leaves open confirmation of benefits by randomized trials.
Atrial fibrillation is associated with significant symptoms, comorbidities, and shared pathophysiological features with heart failure with preserved ejection fraction. We propose that exercise testing, including cardiopulmonary exercise testing and exercise cardiac imaging, can unmask subclinical cardiac dysfunction, guide diagnosis and inform intervention. Exercise training has a key role in atrial fibrillation management, improving arrhythmia burden, atrial remodeling and quality of life.

Dziano et al. (2026) conducted a review in Atrial fibrillation. Exercise testing and training was evaluated. Exercise testing and training can unmask subclinical cardiac dysfunction, guide diagnosis, and improve arrhythmia burden, atrial remodeling, and quality of life in atrial fibrillation.
