Adults with heart failure with preserved ejection fraction (HFpEF) responded more favourably to an exercise intervention compared with those with reduced ejection fraction. This study explores factors that contributed to this response, focusing on the qualitative perceptions of adults with HFpEF enrolled in an exercise intervention.

METHODS AND RESULTS

This qualitative descriptive study is a secondary analysis of longitudinal interviews collected at 3, 6, 12, and 18 months from participants with HFpEF enrolled in a randomized controlled trial testing an intervention to promote adherence to exercise. We included participants with at least two interviews. Interviews were examined across and within participants and time points using thematic analysis. Analyses included 67 interviews from 21 adults with HFpEF enrolled in the intervention arm. The sample consisted of 52% (11/21) males and over 47% (10/21) non-White participants. Mean age at enrolment was 63.7 ± 9.9 years. We identified four major themes: (1) overcoming negative attitudes, barriers, and injury, (2) motivations to exercise, (3) exercise-the panacea for HFpEF symptoms and quality of life, and (4) advice for others with HFpEF.

CONCLUSION

Our findings suggest that for many adults with HFpEF, initial hesitancy, fear, and negative attitudes about exercise can be overcome. Exercise coaching using social cognitive constructs, medical fitness centre memberships, and heart rate self-monitoring are successful strategies of engaging adults with HFpEF in long-term unsupervised exercise training.
