An estimated 26 million patients worldwide experience heart failure, a syndrome associated with major symptoms and a significant increase in mortality. Treatment involves a variety of drugs, and dietary interventions generally include salt restriction. However, the evidence that salt restriction is beneficial for individuals at risk of cardiovascular disease is inconsistent and inadequate. A 2018 systematic review surveyed randomized controlled trials testing the impact of salt intake reduction in adults with heart failure and found insufficient research and trial results to support this oft-prescribed intervention.
