Salt Substitution and Cardiovascular Events: UPDATE IN MEDICINE

Villagers participated in a cluster-randomized study, in which they were given a choice between using a salt replacement that included 75 percent sodium chloride and 25 percent potassium chloride by mass or using ordinary table salt.
Using the salt substitute was associated with lower incidence of stroke, major cardiovascular events, and death among those who had a history of stroke or were at least 60 years old and had hypertension. The salt substitute did not appear to have any substantial adverse effects.

Conclusion

People who had a history of stroke or who were at least 60 years old and had high blood pressure had lower rates of stroke, major cardiovascular events, and death from any cause when they used the salt substitute rather than regular salt. This was the case regardless of whether or not they had high blood pressure.
