Impact of Dietary Sodium Restriction on Heart Failure Outcomes.

ABSTRACT:

Objectives

This study sought to evaluate the impact of sodium restriction on heart failure (HF) outcomes.

Background

Although sodium restriction is advised for patients with HF, data on sodium restriction and HF outcomes are inconsistent.

Methods

We analyzed data from the multihospital HF Adherence and Retention Trial, which enrolled 902 New York Heart Association functional class II/III HF patients and followed them up for a median of 36 months. Sodium intake was serially assessed by a food frequency questionnaire. Based on the mean daily sodium intake prior to the first event of death or HF hospitalization, patients were classified into sodium restricted (<2,500 mg/d) and unrestricted (≥2,500 mg/d) groups. Study groups were propensity score matched according to plau
