AF leads to electrical remodelling and fibrosis of the atria; however, the mechanism(s) remain poorly understood. Galectin-3 is a potential mediator of cardiac fibrosis. The present study aimed to examine the relationship between serum galectin-3 levels and paroxysmal AF. Methods: Forty-six patients with paroxysmal AF and preserved left ventricular systolic function, and 38 age-and gender-matched control subjects, were involved in the study. Serum galectin-3 levels were analyzed with an enzyme-linked immunosorbent assay (ELISA). Results: Serum galectin-3 levels (median 1.38 ng/mL; 1.21 ng/mL-1.87 ng/mL; p < 0.001) were significantly elevated in patients with paroxysmal AF compared with the control. Left atrial diameter was significantly higher in patients with paroxysmal AF (41.2 +/- 3.0 mm vs. 39.6 +/- 3.3 mm). Left atrial diameter was found to be significantly correlated with serum galectin-3 levels in patients with paroxysmal AF (r= 0.378, p = 0.001). Conclusion: Serum galectin-3 levels are significantly elevated and significantly correlated with left atrial diameter in patients with paroxysmal AF.eninfo:eu-repo/semantics/closedAccessHeart-FailureFibrosisMechanismsRiskCommunityDiseaseArticle396S197S202279178182-s2.0-85047586594Q2WOS:000389725000038Q4
