Background: Multidisciplinary heart failure(HF) programs reduce hospital readmission and improve clinical outcomes. Although dietitians are often members of such teams, no randomized studies have demonstrated the independent benefit of dietitian-administered dietary counseling for patients with HF. The purpose of this study was to evaluate the effect of dietitian education on adherence to a sodium-restricted diet in ambulatory patients with stable HF. Methods: Patients with HF(left ventricular ejection fraction< 35% ) were randomized into a dietitian education group(n=23) or a usual care group(n=24), then observed for 3 months. Both groups received a 2 g/d dietary sodium prescription. The usual care group received nutrition advice by way of self-help literature, whereas the dietitian education group returned for 2 counseling sessions with a dietitian. Results: Dietitian education resulted in a significant decrease in sodium intake at 3 months(2.80± 0.30 to 2.14± 0.23 g/d, P< .05). In contrast, there was no change in sodium intake in the usual care group(3.00± 0.31 to 2.74± 0.35 g/d, P=ns). Conclusions: Dietitian-admin-istered counseling was more effective than providing literature in reducing dietary sodium intake in patients with stable HF.
