PURPOSE: Patients with heart failure with preserved ejection fraction (HFpEF) have significant impairments in patient-reported outcomes (PRO) including physical functioning and quality of life (QOL). We conducted a meta-analysis of randomized clinical trials of supervised exercise training (SET) to examine the efficacy of such training.
METHODS: We included six single-blinded SET trials in patients with HFpEF, defined as a left ventricular EF ≥50%, published since 2010 in which participants were randomized to a facility-based exercise training program or usual care. We identified trials from a 2024 Cochrane review of exercise-based cardiac rehabilitation for adults with heart failure as well as other reviews and meta-analyses in PubMed. We used random effects meta-analysis to estimate the respective SET effects for five endpoints: the 36-Item Short Form Survey (SF-36) Physical Functioning Scale (PFS), the SF-36 Physical Component Summary, the Minnesota Living With Heart Failure Questionnaire (MLWHFQ) total score, the Kansas City Cardiomyopathy Questionnaire (KCCQ) Overall Summary Score, and the KCCQ QOL subscale.
RESULTS: The treatment effect estimate favored SET for all five endpoints. However, the SET effect was only statistically significant for the SF-36 PFS ( P < .0001) and the MLWHFQ total score ( P = .01).
CONCLUSIONS: This meta-analysis demonstrated clear evidence that patient-reported physical functioning, an outcome that patients with HFpEF identify as a prominent disability, is significantly improved with SET. It also showed consistent improvements across several other multi-dimensional measures of QOL.
