Current national and international guidelines for the management of heart failure include advice to reduce salt intake. However they consistently make reference to a lack of evidence underpinning this advice. A recent review on this topic suggested potential harm from such diets but was latterly retracted after serious concerns over the quality of its findings. There currently is no evidence to suggest any benefit from advocating this treatment despite this being part of NHS guidelines.
This review will be the start of a body of work that will help future guidelines advice on whether there is any benefit (or harm) to low salt diets in heart failure patients.
