Background: Protein-calorie malnutrition and micronutrient deficiencies are common and associated with adverse outcomes in heart failure (HF). We hypothesized that low sodium intake is related to low energy intake and dietary micronutrient deficiencies in elderly HF patients.
Methods: In GOURMET-HF (NCT02148679), a study evaluating home-delivered meals in elderly HF patients post-hospital discharge, Food Frequency Questionnaires (FFQ) were used to estimate baseline intake of energy, sodium, and other micronutrients. Dietary micronutrient deficiency was scored: 1 point for each of 16 micronutrients below Dietary Reference Intake (DRI) thresholds. Excess energy available was calculated as (FFQ-estimated energy intake – DRI-recommended energy intake).
Results: In 37 patients (age 71±8, 78% male, BMI 31±6 kg/m2), energy intake was 1,650 (IQR 1,137-1,855) kcal/d and sodium intake 2,483 (2,080-3,270) mg/d. Energy and sodium intake were strongly correlated (r=0.95, p<0.001). Dietary micronutrient deficiency was more extensive below the median sodium intake (10±3 vs. 5±3 points, p<0.001; Figure A). The average energy balance was negative [available energy −555 (-963 to −35) kcal/d] and closely aligned with sodium intake (Figure B).
Conclusions: In elderly HF patients, low sodium intake is associated with dietary micronutrient deficiencies and low overall energy intake. Recommendations to restrict sodium in HF may have unintended consequences unless overall diet quality is maintained.
