A high prevalence of malnutrition has been reported in hospitalized patients with acute heart failure and some studies suggest that personalized treatments or interventions on nutritional status could improve prognosis in these patients. Previous studies have shown that malnutrition is an independent factor associated with worse prognosis not only in hospitalized patients with decompensated HF but also in patients with chronic stable HF. In this sense, it has been postulated that nutritional intervention in malnourished patients with HF could have some prognostic benefit. However, there are very few data published in the literature that have assessed the nutritional status and the benefit of a nutritional intervention in stable ambulatory patients with chronic HF.~Therefore, the aim of this study was to evaluate whether the application of an educational and nutritional intervention in malnourished patients with heart failure improves prognosis, nutritional status, functional capacity and quality of life.
Malnutrition is common in patients with heart failure (HF) and is associated with a worse prognosis.~However, there is little information on the impact of nutritional intervention in malnourished patients with heart failure. Therefore, the aim of our study is to evaluate whether a specific nutritional intervention has an impact on mortality and hospitalizations, quality of life, nutritional status, and functional capacity in patient with heart failure and malnutrition.
