Body mass index-adjusted rectus femoris muscle thickness ≥0.55 was associated with a significantly lower risk of subthreshold oxygen uptake at the anaerobic threshold <10.5 mL/min/kg (aRR 0.22) in patients with heart failure.

Is rectus femoris muscle thickness adjusted by body mass index (RFT/BMI) associated with oxygen uptake at anaerobic threshold (AT-V̇O2) in patients with heart failure?
The study evaluates whether body mass index-adjusted rectus femoris muscle thickness can serve as a simple indicator for exercise tolerance in heart failure patients.
Relative Risk: 0.22 (95% CI 0.09–0.53)
p-value: p=0.001
Background: We evaluated the association between rectus femoris muscle thickness adjusted by body mass index (RFT/BMI) and oxygen uptake at anaerobic threshold (AT-V̇O2) in patients with heart failure (HF) to assess whether RFT/BMI was associated with AT-V̇O2, a key indicator of exercise tolerance and a known prognostic factor in HF.
Suyama et al. (Mon,) conducted a cross-sectional in Heart failure (n=103). Body mass index-adjusted rectus femoris muscle thickness (RFT/BMI) ≥0.55 vs. RFT/BMI <0.55 was evaluated on Risk of oxygen uptake at anaerobic threshold (AT-VO2) <10.5 mL/min/kg (aRR 0.22, 95% CI 0.09 to 0.53, p=0.001). Body mass index-adjusted rectus femoris muscle thickness ≥0.55 was associated with a significantly lower risk of subthreshold oxygen uptake at the anaerobic threshold <10.5 mL/min/kg (aRR 0.22) in patients with heart failure.
