Galectin-3 is a new biomarker that is assumed to reflect fibrogenesis and inflammation. In this study, we aimed to evaluate the levels of galectin-3 in patients with acute coronary syndrome (ACS) and the relation of galectin-3 to the burden of atherosclerosis. Nineteen patients with ACS who underwent coronary angiography and 17 age-matched healthy controls were enrolled. The burden of atherosclerosis was assessed with Gensini score and with the number of involved vessels. Galectin-3 levels were measured on admission by using ELISA. The mean age of the cohort was 62.8±10.6 and 56% of the patients were male. Compared to control group, median galectin-3 levels were significantly higher in ACS patients (0.77ng/mL [0.50-1.19] vs. 0.51ng/mL [0.41-0.78], P=0.01). Patients were classified into three groups according to the number of involved vessels. Median galectin-3 levels did not differ significantly among groups (one vessel: 0.68ng/mL [0.55-0.74], two vessels: 0.67ng/mL [0.46-1.84], three vessels 0.90ng/mL [0.53-1.38], P=0.62). There was a strong correlation between galectin-3 levels and Gensini score (r=0.625, P=0.004). In conclusion, galectin-3 levels were elevated in patients with ACS and there was a strong correlation between galectin-3 levels and Gensini score.
