The goal (or purpose) of this study is to evaluate (study) a new way to stabilize (steady) the activity between the fat deposits surrounding the heart and the left atrium. To reduce the amount of EAT, this study will use a medication called Liraglutide. This medication is known to work on fat deposits and produce weight loss. The investigator is conducting this study to find out if Liraglutide will reduce the fat deposits surrounding the participant's heart, and stabilize (and perhaps reduce or eliminate) atrial fibrillation activity.
Active comparator
Risk Factor Modification (RFM)
A structured risk factor modification (RFM) program currently offered to all patients who are overweight or obese undergoing an ablation procedure for atrial fibrillation.The RFM program is already offered through our Center for Atrial Fibrillation and is managed by a nurse practitioner. The RFM program will provide patient teaching and education on weight, fitness,blood pressure control, glucose control, cholesterol, sleep apnea, smoking, and alcohol.
Experimental
RFM plus Liraglutide
In addition to RFM, Liraglutide will be administered. Liraglutide is an FDA approved medication used as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management of obese adults with weight-related comorbid conditions.
