Increased prevalence of atrial fibrillation (Afib) among aging baby boomers has sparked debate among cardiologists about a so-called epidemic of Afib, with some data suggesting that as many as 20% of seniors over 80 will develop the condition. And although age is the most heavily weighted risk factor for the arrhythmia, specialists are beginning to see another population group emerge with its own unique predisposition for Afib: lifelong endurance athletes.

Studies comparing rates of atrial fibrillation among long distance athletes with age-matched control groups have found the incidence of Afib is as much as seven times higher in vigorous exercisers. Experts are starting to understand the underlying physiology that sets up the endurance athlete for vulnerability to Afib. Of particular interest is the impact of intense exercise on atrial remodeling.

Treating this specialized group calls for cardiologists to personalize their approach, finding a balance for patients committed to continuing a highly active lifestyle while minimizing symptoms and risk for stroke.
