There are no clinically relevant data on whether reduced dietary salt intake affects mortality, cardiovascular-associated events, hospitalization, or length of hospital stay in heart failure. Moreover, in the new study, Mahtani with colleagues have shown, salt intake does not appear to influence the frequency or severity of heart failure symptoms.
Despite this, the current clinical practice should not be changed for these patients. Anywhere lower salt intake is associated with minimum health risks and reducing sodium intake may decrease the risk of morbidity and mortality due to some cardiovascular diseases like arterial hypertension. New data are on the way with the Study of Dietary Intervention Under 100 MMOL in Heart Failure (SODIUM-HF), which is now in progress.
