Anabolic steroid abuse may be a risk factor for atrial fibrillation. - GreenMedInfo Summary

Atrial fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice. The prevalence of AF increases with age, and this age-specific prevalence is higher in men than in women. However, the mechanisms of aging-induced AF have not been fully elucidated, and this may be related to decline of testosterone with advancing age. On the other hand, anabolic steroid abuse may precipitate the occurrence of AF. Until now, the possible relationship between androgens and AF was not comprehensively reviewed. We intend to review some recent evidence on this issue and propose some potential mechanisms.
