To the Editor: Dr O’Donnell and colleagues, in their study on urinary sodium excretion and risk of cardiovascular events,1 reached the counterintuitive conclusion that sodium restriction increased the risk of cardiovascular events, which runs counter to the consistent evidence that, in individuals with hypertension, decreased sodium intake reduces blood pressure and improves the effectiveness of treatment with antihypertensive agents.2- 4
