Heart failure is the final route of most heart diseases and is a worldwide problem due to its high prevalence, morbidity and mortality. In Brazil, it is an important cause of hospitalization and one of the most important health challenges, since its prevalence tends to increase with the aging of the population and the increase in the survival of patients who have suffered acute coronary events. This is an ongoing epidemic problem, resulting in a high socioeconomic cost, represented by the expense of medications, repeated hospitalizations, loss of productivity, early retirements, possible surgeries and, ultimately, heart transplantation. In this sense, it is of great importance to carry out studies that evaluate the possible benefits of new clinical and nutritional interventions for HF patients, favoring the development of treatment strategies for these individuals and also for public health.
