Heart failure with preserved ejection fraction (HFpEF) incidence and prevalence is increasing, and the phenotype associated with obesity is the most frequent. Epicardial adipose tissue (EAT) is directly associated with systemic obesity and several previous studies have shown a clear link between EAT and HFpEF. Moreover, the restriction induced by the pericardium is also linked to HFpEF. In this review we will describe the epidemiological association between the pericardium, EAT and HFpEF, how to quantify EAT, what are the pathophysiological mechanism to explain theses association and how can the pericardium and EAT be a treatment target in patients with HFpEF.
