Predictive value of nesfatin-1 in heart failure mortality

OpenAlex English

Abstract Objectives Advanced heart failure is the last stage of heart failure in which the life expectancy of patients is significantly reduced. Many mortality markers have been identified in advanced heart failure. Although the nesfatin-1 molecule is known as a satiety hormone, it has also been shown to be associated with many cardiovascular diseases. This study aims to elucidate the association between in-hospital mortality and nesfatin-1 level in advanced heart failure patients. Methods The research included 74 cases of advanced heart failure. During the coronary intensive care surveillance of these patients, 22 patients had in-hospital mortality. The cases, divided into groups with and without in-hospital mortality, were compared using laboratory data, echocardiography, and demographic properties. Results The age of the cases with in-hospital mortality was older than the cases without mortality [(74 (66–95) vs. 67 (26–90); p=0.019)]. Serum nesfatin-1 level and tricuspid annular plane systolic excursion (TAPSE) were statistically lower in the in-hospital mortality group (43.8 ± 5.5 vs. 40.5 ± 6.1; p=0.027, 13.5 ± 1.9 vs. 16.2 ± 2.6 p=0.001, respectively). Serum nesfatin-1 level and TAPSE were detected as independent predictors for in-hospital mortality in advanced heart failure via multivariate analysis using parameters that were significant in the univariate analysis. Receiver operator characteristic curve analysis showed that the optimum cut-off level for nesfatin-1 in determining in-hospital mortality was ≤23.57 (pg/mL) with a specificity of 73.1 % and a sensitivity of 77.3 % (AUC=0.763, 95 % CI=0.647–0.879, p<0.001). Conclusions This research revealed that in advanced heart failure patients, serum nesfatin-1 amounts are associated with mortality and seem to be an independent predictor of mortality.
