Abstract

BACKGROUND: Exercise intolerance is the primary chronic symptom in patients with heart failure and preserved ejection fraction (HFPEF), the most common form of heart failure in older persons, and can result from abnormalities in cardiac, vascular, and skeletal muscle, which can be further worsened by physical deconditioning. However, it is unknown whether skeletal muscle abnormalities contribute to exercise intolerance in HFPEF patients. METHODS: This study evaluated lean body mass, peak exercise oxygen consumption (VO2), and the short physical performance battery in 60 older (69 ± 7 years) HFPEF patients and 40 age-matched healthy controls. RESULTS: In HFPEF versus healthy controls, peak percent total lean mass (60.1 ± 0.8% vs. 66.6 ± 1.0%, p < .0001) and leg lean mass (57.9 ± 0.9% vs. 63.7 ± 1.1%, p = .0001) were significantly reduced. Peak VO2 was severely reduced including when indexed to leg lean mass (79.3 ± 18.5 vs. 104.3 ± 20.4 ml/kg/min, p < .0001). Peak VO2 was correlated with percent total (r = .51) and leg lean mass (.52, both p < .0001). The slope of the relationship of peak VO2 with percent leg lean mass was markedly reduced in HFPEF (11 ± 5 ml/min) versus healthy controls (36 ± 5 ml/min; p < .001). Short physical performance battery was reduced (9.9 ± 1.4 vs. 11.3 ± 0.8) and correlated with peak VO2 and total and leg lean mass (all p < .001). CONCLUSION: Older HFPEF patients have significantly reduced percent total and leg lean mass and physical functional performance compared with healthy controls. The markedly decreased peak VO2 indexed to lean body mass in HFPEF versus healthy controls suggests that abnormalities in skeletal muscle perfusion and/or metabolism contribute to the severe exercise intolerance in older HFPEF patients.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
