Expressions and significance of peripheral galectin-3 and N-terminal B-type brain natriuretic peptide in patients with chronic heart failure

Objective To explore the change of peripheral galectin (Gal)-3 and N-terminal B-type brain natriuretic peptide (NT-proBNP) in patients with chronic heart failure.Methods A total of 89 patients with chronic heart failure (CHF) were enrolled.Peripheral Gal-3,NT-proBNP were detected by enzyme-linked immunosorbent assay (ELISA) or Electrochemical luminescence method.The expression levels of Gal-3,NT-proBNP in patients with different kinds of heart failure and cardiac functional grading were analyzed.Results There were significant differences in expression levels of Gal-3 and NT-proBNP between patients with HFPEF and patients with HFREF.There was significant differences of Gal-3 and NT-proBNP in patients with NYHA heart function class Ⅱ,Ⅲ and Ⅳ.Gal3 was positively correlated with NT-proBNP (r =0.230,P =0.030) and negatively correlated with LVEF (r =-0.533,P =0.000).NT-proBNP was negatively correlated with LVEF (r =-0.372,P =0.000).Conclusion Peripheral Gal-3,NT-proBNP could be considered as two important markers for judging severity of illness in patients with CHF.
