Yamada S, et al. - This study characterized circulating microRNAs (miRNAs) and assessed their correlation with the clinical outcomes in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). Definite ARVC patients with ventricular arrhythmia (VA) exhibited significantly elevated plasma levels of miR-144-3p, 145-5p, 185-5p, and 494. In addition, in these subjects, an association was evident between elevated plasma level of miR-494 and the recurrence of VA after ablation.
