The Paradox of Elite Athletes and Heart Health
Elite athletes face a paradoxical situation where their rigorous training, typically beneficial for health, may increase the risk of atrial fibrillation (AF), a heart rhythm disorder. Studies indicate that elite rowers have a 20% prevalence of AF compared to just 3% in non-athletes, while women endurance athletes face a three to five times higher risk than their non-athletic counterparts. This anomaly prompts researchers to explore potential causes, including genetic factors and the physical changes in athletes' hearts, which can become enlarged from intensive training. Insights from ongoing studies aim to improve preventive measures and treatments for AF in both athletes and non-athletes alike.
