Heart failure (HF) is highly prevalent in people over the age of 65 years and constitutes a leading cause of hospitalization and death in this population [1,2]. Decompensations are a crucial point in the natural history of HF, because most of deaths and health care costs are linked to them [3,4]. Therefore, it is a priority to identify risk factors linked to decompensations and adverse outcomes, especially death, in order to improve prognosis of patients with HF [5,6].
