Athletic Past and Genetic Factors Increase Atrial Fibrillation Risk

A recent study found that elite rowing and genetic factors can significantly increase the risk of arrhythmia, showing that not all heart risks in athletes are the same.

The study focused on atrial fibrillation (AF), a heart rhythm issue that raises the risk of stroke and heart failure. Risk factors for AF include hypertension, sleep apnea, age, heart disease, alcohol use, and obesity.

Compared to non-athletes, endurance athletes have a higher risk of AF. The exact cause is not fully understood, but factors like inflammation, exercise-induced stress, and cardiac remodeling from years of intense training play a role.

Genetic predisposition may also contribute to AF development in athletes. Elite athletes, especially those with long careers, are at a higher risk of AF even after retirement.

The study involved former elite rowers and matched controls to investigate AF prevalence and genetic links. Results showed that retired athletes had higher AF rates and unique cardiac characteristics compared to the control group.

Further research is needed to understand the genetic factors influencing AF in athletes and to develop better risk assessment strategies.
