Natriuretic peptides and galectin-3 in senile heart failure patients with preserved ejection fraction

Purpose: to characterize biomarker panel in senile patients with heart failure with preserved ejection fraction (HF-pEF). Material and Methods. 356 senile patients with chronic heart failure with preserved ejection fraction (HFpEF) were examined to form the study sample of 48 male patients without atrium fibrillation, anemia, diabetes mellitus, onco-pathology and missing clinical data. NT-proBNP, galectin-3 (gal-3) and proANT assay was performed by commercially available ELISA kits. Results. In patients without left ventricular (LV) regional wall motion abnormalities (RWMA). gal-3 (2,13 (0,98; 3,50) vs 5.16 (4,34;9.63) ng/mL, p = 0.011) and NT-proBNP (5,59 (1,00; 10.13) vs 32,04 (15,40; 46,18) fmol/mL, p=0,006) levels were significantly lower than in patients with LV RWMA. Contrarily proANP level was lower in patients with LV RWMA (3,24 (2,47; 3,75) vs 1,38 (0,83; 2,29) nmol/mL, p=0.071). proANP was the only biomarker to increase significantly in long livers (7,30 (4,52; 7,63) vs 2,68 (1,88; 3,32) nmol/mL, p=0.006). NT-proBNP positively correlated with glucose level and negatively with hsCRP (R=0,52, p=0,007). Conclusion. Biomarker panel in senile heart failure patients with preserved ejection fraction has characterized: increase in NT-proBNP and galectin-3 is associated with more severe clinical course and presence of regional wall motion abnormalities in senile patients.
