CRP and hydrops fetalis: Although a previous cross‐sectional study on patients with HF who participated in outpatient cardiac rehabilitation has demonstrated that 30% of patients were AWGC‐defined cachexia, differences in the prevalence of AWGC‐defined cachexia between ours and the previous study may represent a difference in the population and AWGC‐defined cachexia at an earlier study may be underestimated because they did not have the CRP data [20].
