Abstract P215: A Qualitative Exploration Of Barriers And Facilitators To A Cardiac Rehabilitation-based Weight Loss Program For Patients With Atrial Fibrillation And Obesity.


 Background:
 Cardiac rehabilitation (CR) programs are ideal treatment settings for atrial fibrillation (AF) risk factor management, yet few CR curricula include a behavioral weight loss treatment (BWLT) component for patients with comorbid obesity (BMI ≥ 30 kg/m
 2
 ).
 
 
 Aim:
 To identify perceived barriers, facilitators, and preferences regarding CR with added BWLT among patients with AF and obesity using a qualitative descriptive approach.
 
 
 Methods:
 Patients (18+) with paroxysmal or persistent AF and obesity were recruited from a Canadian AF clinic. Patients completed questionnaires assessing socio-demographic variables and participated in semi-structured interviews to elicit their potential barriers, facilitators, and preferences regarding a proposed 12-week CR+BWLT program (i.e., twice-weekly supervised exercise, risk factor management, and weekly group-based cognitive-behavioral weight management support). Interviews were recorded and transcribed. Conventional content analysis was used to derive themes from qualitative data.
 
 
 Results:
 Twenty patients (9 women; 63±12 years; BMI=35.50±6.00 kg/m
 2
 ) participated. Data were categorized to describe patients' barriers, facilitators, and preferences/perspectives (Figure 1). Four overarching themes emerged from the categories: 1) frustration with weight management; 2) AF symptoms are manageable; 3) AF information needs; and 4) desire for program flexibility.
 
 
 Conclusion & Future Directions:
 The proposal to offer BWLT alongside CR was acceptable to patients with AF and obesity, with most reporting few barriers to participating. The results will inform AF-specific adaptations to an established BWLT (e.g., modules on AF pathophysiology and exercise recommendations). The AF-adapted BWLT will be piloted in the target population prior to testing the full intervention package in a randomized controlled trial. The novel combination of CR+BWLT, tailored to an AF population, has potential to improve AF management and outcomes for patients with comorbid obesity.
