LGALS3 and atherosclerosis: The aim of the study was to analyse whether the Gal-3 concentration assessed during at least a 24-month period following MI has any prognostic value, and whether it reflects the progression of atherosclerosis and correlates with the intima-media thickness (IMT) complex and the presence of atheromatous plaque in carotid arteries in this group of patients during long-term observation.
