About the Pro@Heart Study

Manuscript: Using atrial myopathy metrics to devise a risk prediction tool for atrial fibrillation in endurance athletes - Spencer LW, D'Ambrosio P, et al.

Study Population: This risk model was developed from data on 328 elite and master endurance athletes (77% male, median age 41) from the Pro@Heart and ProAFHeart studies, of whom 77 had atrial fibrillation.

Disclaimer: This tool is an informational resource based on a specific research cohort and is not a substitute for professional medical advice, diagnosis, or treatment. It predicts the prevalence of AF within the study group and has not yet been validated for predicting future (incident) AF.
