Chronic kidney disease (CKD) affects up to 10 % of the general population, being one-third of these individuals over 65 years old [1]. A bidirectional interaction, has been described between CKD and cardiovascular disease [2], with CKD constituting a common comorbidity in patients with heart failure (HF), especially amongst the older population [3,4]. Furthermore, CKD has been consistently associated with worse HF prognosis, leading to higher morbidity and mortality rates [3].
