Dietary Sodium Restriction for Heart Failure: A Systematic Review of Intervention Outcomes and Behavioral Determinants

The 1500mg/day dietary sodium-restriction commonly recommended for patients with heart failure has recently been questioned. Poor adherence to sodium restricted diets makes assessing the efficacy of sodium restriction challenging. Therefore, successful behavioral interventions are needed. We reviewed sodium restriction trials and descriptive studies of sodium restriction to: 1) determine if sodium restriction was achieved in interventions among heart failure patients; and 2) characterize predictors of successful dietary sodium restriction.
