Nutritional orientation , knowledge and quality of diet in heart failure : randomized clinical trial . BACKGROUND Non-pharmacological measures are recommended for heart failure patients . However , most studies evaluate low sodium diet , while little is known about the effects of interventions to improve adherence and knowledge of patients about diet content . OBJECTIVE To evaluate if a global nutritional orientation could affect nutritional knowledge , adherence to food guidelines , anthropometrics and quality of life in heart failure patients . METHODS Forty six patients were randomized to intervention or control group . Both groups received usual care with medical and nursing staff ; the intervention group received additional nutritional guidance about diet and its relationship with disease , sources of nutrients , and reduction of dietary sodium and fats . Enforcement of the nutritional guidance was performed after 4 weeks . Both groups were evaluated at baseline , and after 6 weeks and 6 months . Evaluations included anthropometric parameters , sodium excretion in 24-hour urine , dietary recall , nutrition knowledge and quality of life questionnaires . RESULTS Mean age of included patients was 58 ± 10 years and 70 % were male . After 6 months of follow-up , the nutritional knowledge of intervention group increased compared to control ( p < 0.05 ) . Caloric , fat and sodium intake decreased in the intervention group compared to control ( p < 0.05 ) . No significant differences were seen in quality of life or anthropometric parameters . CONCLUSIONS Nutritional orientation was effective to modify 1 ) knowledge about food and nutrition , and 2 ) quality of diet in outpatients with heart failure . Further studies are necessary to evaluate the benefits on quality of life and prognosis .
