Risk factor modification for the primary and secondary prevention of atrial fibrillation. Part 2

Abstract

Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased risk of death, stroke, and heart failure. Prevalence and incidence of AF are rising due to better overall medical treatment, longer survival, and increasing incidence of cardiometabolic and lifestyle risk factors. Treatment of AF and AF -related complications significantly increases healthcare costs. In addition, the use of conventional rhythm control strategies (including, antiarrhythmic drugs and catheter ablation) is associated with limited efficacy for sinus rhythm maintenance and serious adverse effects. Aggressive cardiometabolic risk factor management may prevent incident as well as recurrent AF, improve overall health, and reduce mortality. Therefore, modifiable risk factor management became one of the 3 treatment pillars in AF management along with anticoagulation as well as conventional rate and rhythm control strategies. The second part of this review systematically discusses the association between AF and potentially modifiable risk factors for AF, such as obesity, obstructive sleep apnea, alcohol consumption, and dyslipidemia. We also provide practical guidelines for the risk factor management with respect to primary and secondary prevention of AF.
