In the study by Frogoudaki et al. [42] of galectin-3 as a risk factor for major cardiovascular events defined as death, hospitalization, worsening functional class or cardiac intervention did not produce optimistic results; however, the concentration of the marker correlated with arrhythmias and was significantly higher in the case of patients presenting supraventricular or ventricular tachycardia. This evidence concerns the gene LGALS3 and ventricular tachycardia.
