In our study, ROC analysis reveals statistically significant correlation (AUC 0.73, SE 0.1, p = 0.04) between the arrhythmia number and galectin-3 plasma level, which confirms the hypothesis that dyssynchronous contractile activity due to ventricular arrhythmia is the ground for myocardial degeneration. The gene discussed is LGALS3; the disease is cardiac arrhythmia.
