Abstract

Summary: Purpose: Losses of peripheral muscle mass and ectopic fat accumulation have been associated with cardiometabolic morbidity in COPD . We aimed at identifying the relationship between quadriceps muscle fat infiltration and cardiovascular risk. Materials and methods: From 2009 to 2014, 78 COPD patients (64 ± 8 years; 80% male) were prospectively included after having given written consent (ethical committee approval number: 2006‐A00491‐50). The cohort was divided into three groups (tertiles) according to body mass index ( BMI ), low [15 < BMI ≤23·3], middle [23·3 < BMI ≤27·6] and high [27·6 < BMI ≤36] kg/m²). Measurements were respiratory function, plasmatic biomarkers and surrogate markers of cardiovascular risk (arterial stiffness and endothelial function). Mid‐thigh quadriceps muscle volume and per cent of muscle fat infiltration, as assessed by 64‐slice CT scanning, were compared between the tertiles. ANOVA or Kruskal–Wallis tests were used for statistical analyses with Bonferroni's correction for the ‘post hoc’ tests. Results: Intramuscular fat volume was 52% [95% CI , 43 to 60%] of total quadriceps volume in high BMI vs. 47% [38 to 55%] and 34% [29 to 38%] in the middle and low‐ BMI groups, respectively ( P <0·0001), without differences between groups in fat‐free muscle volumes. Elevated muscle fat infiltration correlated with lower thiol to protein ratios in the whole population reflecting impaired antioxidant capacity ( r = 0·50; P = 0·009). Furthermore, muscle fat infiltration was linked to endothelial dysfunction ( r = −0·49, P = 0·01) in the low‐ BMI group. Conclusion: Skeletal muscle fat infiltration may be an indicator of increased cardiometabolic risk in both obese and lean COPD patients.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The redistribution of fat does not necessarily manifest as obesity, but intramuscular fat infiltration generally increases the chances of progression to obesity across adults.

    “It is noteworthy that while the redistribution of fat does not necessarily manifest as obesity, intramuscular fat infiltration generally increases the chances of progression to obesity across adults.[ 11 ]”
  • Clinical data showed that skeletal muscle fat infiltration occurred in both lean and obese individuals, although the infiltrated muscle volume was positively associated with body mass index (BMI).

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.
