Does a low-salt diet reduce morbidity and mortality in congestive heart failure?

Abstract

No randomized controlled trials (RCTs) have addressed the independent role of sodium restriction in the morbidity or mortality of congestive heart failure. However, current guidelines recommend sodium restriction for secondary prevention of congestive heart failure exacerbation.(Grade of recommendation: D.) Clinical trials of multifactorial, nondrug interventions have shown an association of sodium restriction with reduced morbidity and improved quality of life in some populations with congestive heart failure.(Grade of recommendation: C.)
