What is the recommended daily sodium intake for patients with symptomatic heart failure according to the AHA/ACC?

The recommended daily sodium intake for patients with symptomatic heart failure according to the American Heart Association (AHA) and American College of Cardiology (ACC) guidelines is less than 2 grams. This recommendation is based on evidence that reducing sodium intake can help manage fluid retention, lower blood pressure, and improve symptoms in individuals with heart failure. Patients with heart failure often experience congestion due to volume overload, and sodium is a key contributor to fluid retention. By limiting sodium intake, patients may experience fewer symptoms and a better quality of life.

The suggestion that less than 3 grams is appropriate does not sufficiently address the goal of managing symptoms in patients with heart failure. Higher sodium limits, like 3 grams or 4 grams, may still lead to increased fluid retention and exacerbate heart failure symptoms, which is why a stricter limit is advised.
