INTRODUCTION: The prevalence of malnutrition in ambulatory patients with heart failure is difficult to determine, depending on the timing and methodology. OBJECTIVE: To determine the nutritional status of outpatients with systolic heart failure with the Mini Nutritional Assessment (MNA) full and short-form versions, and evaluate its relationship with the short-term prognosis, biomarkers and quality of life. METHODS: Fifty consecutive (70% male), geriatric (74.3+ 6.2years old) stable outpatient with heart failure (NYHA class II 68%, III 32%) and left ventricular ejection fraction of 26.7 +11.5% were included and followed during 12 months. At a routine visit to the heart failure clinic, the MNA, the Minnesota Living with Heart Failure questionnaire (MLHFQ) were applied. According to the MNA screening score the nutritional status was classified using the MNA full (MNA-F) and the short-form (MNA-F) versions of the questionnaire. The recorded events were death and hospitalization. Statistics: The-survival and hospitalizations curves were evaluated with the Log-Rank test and Cox Regression analysis. The association between parameters was analyzed with the Pearson and Spearmann correlation coefficient. RESULTS: (1) The mortality and hospitalization rates were 12% and 42%, respectively. (2) With the MNA-SF 7.6% of the patients had malnutrition and 20% were at risk of malnutrition. There was a good agreement (90%) between the MNA-SF and the MNA-F classifications. (3) There was a significant relationship between the MNA screening score and the MLHFQ (rs= −0.592 p
