RESUMO
A obesity paradox has been described following heart failure (HF). The aim of this study was to analyze the association between food intake-involved adipokines and long-term weight changes. Leptin, adiponectin, and omentin were analyzed in 92 acute HF (AHF) patients at discharge, classified on the basis of weight gains or losses > 6%. The mean follow-up was 256 ± 143 days. Leptin and adiponectin levels were similar among weight groups. However, omentin levels were higher in those patients who had gained weight (16 ± 5 ng/mL) than in those who had lost weight (12 ± 4 ng/mL) or showed no weight change (11 ± 5 ng/mL; p < 0.002). Omentin levels were the best independent predictors for patients with weight gain, who had less mortality and hospital readmission during the follow-up. The association between omentin levels and weight gain might explain part of the obesity paradox in HF.
