Ocular choroidal thickness reflects systemic recovery after acute heart failure: a pilot observational study.

While these differences did not reach statistical significance, total body water (29 ± 5 vs. 34 ± 4 L, P = 0.03), intracellular water (16 ± 3 vs. 19 ± 2 L, P = 0.04), and extracellular water (13 ± 2 vs. 15 ± 2 L, P = 0.03) were significantly lower in the HFrEF group.

At the time of the first evaluation, patients with HFrEF showed a trend toward lower body weight (kg), body mass index (BMI; kg/m2), fat-free mass (kg), and skeletal muscle mass (kg) compared to those with non-HFrEF.
