“Circulating BDNF in Patients With Atrial Fibrillation Undergoing Catheter Ablation or Exercise Training”
The main purpose of this project is to determine the impact of atrial fibrillation interventions (catheter ablation and exercise training) on circulating BDNF concentrations in patients with atrial fibrillation. It also seeks to determine if there is a relation between circulating BDNF concentrations and mental health (depression severity, quality of life and symptoms) among those undergoing interventions for atrial fibrillation catheter ablation or exercise training.
Procedure - Catheter ablation
Subjects undergoing catheter ablation for the first time for atrial fibrillation as part of their regular care (regardless of involvement in this study).
Behavioral - Exercise training
Subjects participating in supervised exercise classes for up to 60 minutes in length 2 times/week as part of their involvement in another study (NCT02602457).
