Prospective study finds increased atrial fibrillation risk linked to training and paternal history in endurance athletes, suggesting sex differences matter.
Key Points
Increased atrial fibrillation detected in male former elite athletes, correlating with paternal history.
Analysis involved 63-year-old endurance athletes with a 38-year follow-up period post-training.
Prospective studies support the notion of higher risk in males vs females due to biological sex differences.
Results highlight the need for caution when recommending universal ECG for all older athletes based on limited AF cases.
