Heart failure (HF) is a highly prevalent disease in the general population which requires repeat hospitalization and causes significant morbidity and mortality (Ponikowski et al., 2016;Yancy, Jessup, & Bozkurt, 2017). As a consequence of this serious outcomes, HF results in a high economic burden for healthcare systems. Therefore, early recognition of poor outcome predictors is essential for patient management.Mortality occurs commonly due to pump failure or arrhythmogenic episodes (Goldstein & Hjalmarson, 1999;Narang, Clelandf, & Erhardt, 1996). Whether ischemic or nonischemic origin, patients with HF have more myocardial fibrosis than healthy subjects which is a substrate for arrhythmias and negative remodeling which gradually decreases left ventricular functions (Bernardo, Weeks,
