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 Arrhythmia.
