Skeletal Muscle Composition and Its Relation to Exercise Intolerance in Older Patients With Heart Failure and Preserved Ejection Fraction
Open accessAbstract
Exercise intolerance is the primary chronic symptom in heart failure with preserved ejection fraction (HFpEF), the most common form of HF in older patients, however its pathophysiology is not well understood. Recent data suggest that peripheral factors, such as skeletal muscle dysfunction, may be important contributors. Therefore, 38 participants, 23 HFpEF patients (69±7 years) and 15 age-matched healthy controls (HC), underwent magnetic resonance imaging and cardiopulmonary exercise testing to assess for: skeletal muscle (SM), intermuscular fat (IMF), subcutaneous fat (SCF), total thigh, and thigh compartment areas (TC) and peak exercise oxygen consumption (peak VO2). There were no significant inter-group differences in total thigh area, TC, SCF, or SM. However, in HFpEF versus HC, IMF area (35.6±11.5 vs. 22.3±7.6 cm2, p=0.01), percent IMF/TC (26±5 vs. 20±5%, p=0.005), and the ratio of IMF/SM (0.38±0.10 vs. 0.28±0.09, p=0.007) were significantly increased, while percent SM/TC was significantly reduced (70±5 vs. 75 ±5, p=0.009). In multivariate analyses, IMF area (partial r= -0.51, p=0.002) and IMF/SM ratio (partial r= -0.45, p=0.006) were independent predictors of peak VO2 while SM area was not (partial r=-0.14, p=0.43). Thus, older HFpEF patients have greater thigh IMF and IMF/SM ratio compared to HC, and these are significantly related to their severely reduced peak VO2. These data suggest that abnormalities in skeletal muscle composition may contribute to the severely reduced exercise capacity in older HFpEF patients. This implicates potential targets for novel therapeutic strategies in this common, debilitating disorder of older persons.

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.
