Effect of Dietary Sodium Restriction in the Management of Patients With Heart Failure and Diastolic Dysfunction
Effect of Dietary Sodium Restriction in the Management of Patients With Heart Failure and Preserved Ejection Fraction: a Randomized Clinical Trial
Although half of the patients with HF has normal ejection fraction or slightly altered (HF-PEF) and the prognosis differs little from those with reduced ejection fraction, the pathophysiology of HF-PEF is still poorly understood.
Sodium restriction is the most common measure of self-care oriented to HF patients for management of congestive episodes. The role of this orientation in the treatment of patients with preserved ejection fraction, however, is still unclear. The evaluation of the effects of sodium restriction on neurohormonal activation and episodes of decompensation in HF-PEF can promote a better understanding of the pathophysiological progression of this complex syndrome.

Intervention / Behandling |
|---|---|
|
Eksperimentel: Intervention
Sodium restriction (1.6g sodium daily - 4g salt) combined with 800 ml of fluid intake
|
Patients that are eligible and fulfill the inclusion criteria will be invited to participate while hospitalized, and then sign the informed consent form. Then, the dietitian on call will be notified in order to change the dietary map of the patients. The prescription diet for both the intervention and control group will be the same: DIET AS RESEARCH PROTOCOL. PATIENT WILL RECEIVE THE DIET UNTIL DAY __ / __ OR DISCHARGE. PLEASE DO NOT CHANGE IT. This will be combined with the medical staff and with the Nutrition and Dietetics service. The evaluation of outcomes after hospital discharge will be held in the institution of reference when will be performed clinical evaluation and blood samples collection for neurohormonal activation analysis. |
|
Ingen indgriben: Control
Normal sodium diet (4g sodium daily - 10g salt) and free fluid intake
