Leptin, tumor necrosis factor-? and insulin resistance in heart failure [Leptina, factor de necrosis tumoral-? y resistencia a la insulina en insuficiencia cardiaca]

Background: Heart failure (HF) is a frequent chronic disease characterized by a heart's pumping inability. There is controversy regarding to changes in leptin and pro-inflammatory cytokines levels in HF, as well as, the compromising of myocardial contractility by insulin sensitivity decreased. The aim of this study was to determine the association of left ventricular ejection fraction (LVEF) with leptin, tumor necrosis factor alpha (TNF-?) and insulin resistance in patients with HF. 1 Material and methods. A cross-sectional study was conducted in 19 HF patients and in 19 healthy volunteers. In all of them, LVEF, cardiac anatomical wholeness and functional class were evaluated; besides, leptin, TNF-?, glucose, creatinine, uric acid, insulin and lipid profile were measured, as well as, insulin resistance by homeostasis model assessment (HOMA-RI) was estimated. Statistical analyses were calculated with Student's t and Pearson's tests. Results. In HF group predominated the functional class II (37%). HF patients in comparison with the control group showed, greater creatinine and uric acid concentrations, as well as, smaller high-density-lipoprotein cholesterol levels and a tendency to be greater the glucose concentrations. There were no significant correlations of LVEF with leptin, TNF-? and HOMA-RI in both groups. Conclusions. LVEF was not associated with leptin, TNF-? and insulin resistance in HF patients
