To establish, through patient and public involvement (PPI) events, the exercise barriers, facilitators and preferences of people with heart failure with preserved ejection fraction (HFpEF).

Qualitative ‘best fit’ framework analysis was used to analyse field notes and transcripts collected during three patient and public involvement meetings and three workshops. The best fit framework was based on the COM-B model of behaviour change, which has identified that Capability, Opportunity and Motivation components are essential for Behaviour change. The Consolidated criteria for Reporting Qualitative research checklist was used to structure the report.

Setting and participants: Community dwelling older adults with HFpEF.

24 people with HFpEF (n=16 female, 66%), 2 spouses and 2 people with chronic conditions participated in the PPI meetings and workshops. Multiple exercise-related capability (negative symptoms, functional ability, resilience and self-efficacy and knowledge and skill); opportunity (appealing components, optimal conditions, adequate support); and motivation factors (well-being, physical gains, goal achievement, sense of enjoyment) were identified as essential to facilitating change in exercise behaviours in people with HFpEF.

This study provides insight into capability, opportunity and motivation conditions that people with HFpEF feel are necessary to enable them to engage in exercise-related behaviour change. This work extends previous post hoc work by moving beyond identification of broad influencers that may enable or impede exercise intervention engagement, to identify intervention conditions necessary to affect change.
