Dietary Sodium Intake and Outcomes in Heart Failure

Currently, the recommendations for sodium intake restriction for patients with heart failure are mostly based on expert consensus and observational evidence, whereas smaller randomized studies have actually suggested that strict dietary sodium reduction may be harmful in heart failure. In the present clinical trial pilot study, the investigators plan to collect data on enrollment rates, compliance, outcomes, and safety of a 12-week dietary intervention in heart failure patients, with prepared food containing two different levels of sodium (1,500 mg and 3,000 mg) daily, followed by a 12-week surveillance for safety and effectiveness. The goal is to inform the design of a fullscale clinical trial that will provide more definitive evidence for dietary sodium recommendations in heart failure.
