Background: The recently discovered myokin Irisin, a peptide originated by a proteolytic cleavage of the transmembrane protein fibronectin type III domain containing 5 (FNDC5) whose expression is induced by exercise and/or by increasing peroxisome proliferator-activated receptor (PPAR)-γ co-activator 1α (PGC-1α), has been considered a prognostic factor in Chronic Ischemic Cardiomyopathy and Acute Heart Failure. Nevertheless, no data are available on Irisin level...

In heart failure with reduced ejection fraction, catabolic mechanisms have a strong negative impact on mortality and morbidity. The relationship between anabolic hormonal deficiency and heart failure with preserved ejection fraction (HFpEF) has still been poorly investigated. On the other hand, oxidative stress is recognized as a player in the pathogenesis of HFpEF. Therefore, we performed a cohort study in HFpEF in order to: 1) define the multi-hormonal deficiency prevalence ...
