As the global burden of atrial fibrillation (AF) and its attendant economic impact on the healthcare system surges, there is increasing interest in the secondary prevention of AF with various therapies. Of the several identified risk factors for AF, obesity is an important contributor that may be managed with intensive lifestyle modification. Prior studies have demonstrated the short-term and long-term benefits of weight loss in reduction of AF symptoms. In the LEGACY study [Long-Term Effect of Goal-Directed Weight Management in an Atrial Fibrillation Cohort: A Long-Term Follow-Up Study], the investigators evaluated the long-term effects of a weight management program on AF symptoms. Of the 355 patients included in this cohort, outcomes such as AF symptom burden, arrhythmia-free survival, inflammatory markers and structural cardiac changes all appear to have improved in the intense weight loss group as compared to the 2 other groups. Further, the benefits of weight loss appear to be lost when > 5% weight fluctuation (WF) occurred over the 5-year follow-up period. In this review, we discuss the design of the weight management clinic and its impact on the management of AF in the LEGACY study. Given that weight management appears to be an effective intervention that will not have the marketing and financial push that pharmaceutical and device based therapies enjoy, it behooves administrators of AF clinics to develop innovative funding strategies to incorporate weight management programs in order to improve patient-centered outcomes.
