نبذة مختصرة : Objectives. Galectin-3 (gal-3) is a mediator of extracellular matrix metabolism and reflects an ongoing cardiac fibrotic process. The aim of this study was to determine the potential use of gal-3 in evaluating the structural and functional parameters of the right ventricle as determined by echocardiography. Design. Ninety-one patients undergoing routine echocardiography were prospectively enrolled in this monocentric study. Serum samples for gal-3 and aminoterminal pro-brain natriuretic peptide (NT-proBNP) were collected within 24 h of echocardiographic examination. Patients were arbitrarily divided into subgroups based on right ventricular function as measured by tricuspid annular plane systolic excursion (TAPSE) and these included TAPSE >24 mm (n = 23); TAPSE 18-24 mm (n = 55); TAPSE ≤17 mm (n = 13); permitting the detailed statistical analysis of derived data. Results. Serum levels of gal-3 in all patients correlated with age (r = 0.36. p
