Comparison of multiple biomarkers for mortality prediction in patients with acute heart failure of ischemic and nonischemic etiology

Abstract

Aim: To investigate the prognosis of soluble ST2 (sST2), galectin-3 and N-terminal pro-B-type natriuretic peptide (NT-proBNP) for death related to ischemic and nonischemic etiology of acute heart failure (HF). Methods: The associations between biomarkers and death were determined in 1020 patients admitted to hospital with acute HF. Results: During 1-year follow-up, 162 patients died. Multivariable regression analysis showed that the hazard ratios of sST2 and NT-proBNP for 1-year all-cause death was similar and remained significant between ischemic and nonischemic HF patients. However, galectin-3 was not significantly associated with death when sST2 and NT-proBNP were incorporated into model in ischemic HF patients. Conclusion: There is no etiology dependent prognostic ability of NT-proBNP or ST2 in patients with acute HF, but for galectin-3 there is no added prognostic ability in ischemic HF.
