Switching from regular dietary salt to a potassium-based substitute improves blood pressure control in individuals with resistant hypertension.
Lifestyle-based interventions, particularly sodium restriction and potassium enrichment, are increasingly recognized as valuable supportive strategies for managing blood pressure (BP). However, evidence assessing potassium-enriched salt substitutes specifically in resistant arterial hypertension (RAH) remains restricted. Researchers therefore investigated whether replacing regular dietary salt with a potassium-enriched salt substitute could improve ambulatory blood pressure monitoring (ABPM) while maintaining safety in adults with RAH.
Investigators conducted a randomized, double-blind, controlled pilot trial involving adults diagnosed with RAH. Participants were randomly assigned to receive either a potassium-enriched salt substitute containing approximately equal proportions of sodium chloride and potassium chloride or conventional table salt over a 24-week intervention period. The primary endpoint focused on changes in :
Analytical comparisons between groups were performed to minimize the effects of white-coat variability and regression toward the mean. Among the 60 participants initially randomized, 49 completed both baseline and follow-up ABPM evaluations.
The pilot study suggested that potassium-enriched salt substitution may serve as a practical and well-tolerated adjunctive strategy for managing RAH. Researchers concluded that replacing conventional salt with a potassium-rich alternative shows encouraging BP-lowering potential without major safety concerns.
