Background:Clinical assessment and treatment guidance for heart failure depends on a variety of biomarkers.The objective of this study was to investigate the prognostic predictive value of growth differentiation factor-15(GDF-15)and N-terminal prohormone of brain natriuretic peptide(NT-proBNP)in assessing hospitalized patients with acute heart failure(AHF).Methods:In total,260 patients who were admitted for AHF in the First Affiliated Hospital of Nanjing Medical University were enrolled from April 2012 to May 2016.Medical history and blood samples were collected within 24 h after the admission.The primary endpoint was the all-cause mortality within 1 year.The patients were divided into survival group and death group based on the endpoint.With established mortality risk factors and serum GDF-15 level,receiver-operator characteristic(ROC)analyses were performed.Cox regression analyses were used to further analyze the combination values of NT-proBNP and GDF-15.Results:Baseline GDF-15 and NT-proBNP were significantly higher amongst deceased than those in survivors(P<0.001).In ROC analyses,area under curve(AUC)for GDF-15 to predict 1-year mortality was 0.707(95%confidence interval[CI]:0.648–0.762,P<0.001),and for NT-proBNP was 0.682(95%CI:0.622–0.738,P<0.001).No statistically significant difference was found between the two markers(P=0.650).Based on the optimal cut-offs(GDF-15:4526.0 ng/L;NT-proBNP:1978.0 ng/L),the combination of GDF-15 and NT-proBNP increased AUC for 1-year mortality prediction(AUC=0.743,95%CI:0.685–0.795,P<0.001).Conclusions:GDF-15,as a prognostic marker in patients with AHF,is not inferior to NT-proBNP.Combining the two markers could provide an early recognition of high-risk patients and improve the prediction values of AHF long-term prognosis.Clinical trial registration:ChiCTR-ONC-12001944,http://www.chictr.org.cn. 展开更多
