Abstract

Aim. To determine whether adherence to a sodium‐restricted diet affects symptom burden and cardiac event‐free survival in patients with heart failure. Background. The recommendation of an sodium‐restricted diet is a standard component of HF management. Therefore, it is important to investigate whether adherence to sodium‐restricted diet is actually associated with improvements in symptom burden and cardiac event‐free survival. Design. A prospective cohort study. Methods. A total of 232 patients [71% male, 65 ± 10 years, 63% New York Heart Association (NYHA) class III/IV, ejection fraction (EF) 30 ± 9%] with HF received 24‐hour urinary sodium excretion (24‐hr UNa) assessments and were divided into two groups using a cut‐off value of 3 g 24‐hr UNa. Symptom burden, including the frequency and severity of heart failure symptoms, was assessed according to the modified Memorial Symptom Assessment Scale‐Heart Failure with a higher score indicating a greater symptom burden. Cardiac event‐free survival over a 12‐month period was determined by reviewing medical records. Results. Patients with 24‐hr UNa ≥ 3 g exhibited greater symptom burdens (β = 0·23, p
