D-PO05-147 - In-office Counseling Alone Is Insufficient For Effecting Weight Change In Patients Undergoing Atrial Fibrillation Ablation (ID 567)


Background: Atrial fibrillation (AF) is a challenging global health problem, and targeting risk factors for AF is a key component in reducing AF burden. In the US, system-wide approaches for integrated risk factor management and counseling are limited and behind in development as compared to advanced ablation techniques.
Objective: For patients undergoing an invasive AF ablation procedure, we sought to explore the progression of patients' weights with basic in-office counseling as part of their AF management plan.
Methods: Using a retrospective chart review of 546 patients who underwent an AF ablation at our center between 2015 and 2019, weights were assessed prior to ablation and a mean of 343 +/- 311 days after the ablation. Patients were given basic education about the effect of obesity on AF and the importance of weight loss in reducing AF burden.
Results: Weight change was distributed broadly as shown in Figure 1. Only 134 of 546 (24.5%) patients were within 2% of their pre-ablation weight. 50 of 546 (9.2%) patients were successful in losing > 10% of their weight. Amongst 103 patients weighing more than 250 lbs (113.6 kg), 36 (35.0%) lost more than 5% of their pre-ablation weight while 19 (18.5%) lost more than 10% of the their pre-ablation weight. Unfortunately, 124 of 546 patients (22.7%) gained more than 5% of their pre-ablation weight.
Conclusion: These data show that basic in-office counseling can be effective for motivated patients and will likely enhance the overall success of AF management. However, in a large quarternary system, many AF patients struggle to lose significant weight, and a more structured, integrated intervention is likely to reap significant benefits in AF reduction.
