Risk factor modification for the primary and secondary prevention of atrial fibrillation. Part 1.

Modifiable risk factors, such as cardiometabolic and lifestyle risk factors, considerably contribute to (bi)atrial remodeling, finally resulting in clinical occurrence of atrial fibrillation (AF). Early identification and prompt intervention on these risk factors may delay further progression of atrial arrhythmia substrate and prevent the occurrence of new‑onset AF. Moreover, in patients with previous history of recurrent AF, aggressive risk factor management may improve efficacy of other rhythm control strategies, including antiarrhythmic drugs and catheter ablation in sinus rhythm maintenance. Finally, modification of risk factors improves overall health and reduces cardiovascular mortality and morbidity. The first part of this review evaluates the association between AF and the following risk factors: hypertension, diabetes mellitus, physical activity, and cigarette smoking. We systematically discuss the impact of risk factor modification on primary and secondary prevention of AF.
