Brief Summary:

The SODA-HF trial is a randomized, double-blind, controlled trial to evaluate the effect of moderate to severe sodium restriction on brain natriuretic peptide in patients with heart failure and reduced ejection fraction (less than 40%).

Secondary outcomes are quality of life, NYHA functional class, glomerular filtration rate, renin plasmatic activity, aldosterone and composite clinical outcome (all-cause mortality and cardiovascular hospitalization)

Arm Intervention/treatment
Experimental: Severe sodium restriction

Patients will be assigned to a diet with two grams of sodium. The nutritionist will be responsible for calculating diets appropriate to the needs of each patient. The diet will not have the intention to modify the weight of the patient but only to indicate the menus that the patients will follow. All the patients will be explained the diet. Patients will be allowed a maximum intake of 1.5 liters of water per day, including the liquid of soups, juices and drinks; This will be explained in detail to the patients.

The diets will be identical in calories according to the weight of the patient. The only difference in diets will be the sodium content, which will be 2 grams of sodium vs. 3 grams of sodium.

Other: Severe sodium restriction
Patients will be assigned to a diet with sodium restriction of two grams.

Active Comparator: Moderate sodium restriction.
Patients will be assigned to a diet with three grams of sodium.
Other: Moderate sodium restriction
Patients will be assigned to a diet with sodium restriction of three grams.

Primary Outcome Measures :
  1. Brain natriuretic peptide [ Time Frame: 20 weeks ]
    Brain natriuretic peptide (NT-proBNP) will be compared at the end of the intervention.

Secondary Outcome Measures :
  1. Quality of life [ Time Frame: 20 weeks ]
    Quality of life will be compared with the Minnesota Living with Heart Failure Questionnaire. This is a self-applied questionnaire that contains 21 items, a total score and two dimensions: physical and emotional. The response options range from 0, which indicates unaffected quality of life, to 5, which indicates the maximum impact on the quality of life. The range of values of the questionnaire in general is 0-105; the physical dimension is 0-40; The emotional dimension is 0-25. In this study we will compare the overall result and the two dimensions.

  2. Measured glomerular filtration rate [ Time Frame: 20 weeks ]
    Measured glomerular filtration rate will be assessed with 24-hour creatinine clearance.

  3. Renin plasmatic activity [ Time Frame: 20 weeks ]
    Renin plasmatic activity will be assessed with ELISA.

  4. Aldosterone [ Time Frame: 20 weeks ]
    Aldosterone will be assessed with ELISA.

  5. Composite clinical outcome [ Time Frame: 20 weeks ]
    All-cause mortality or cardiovascular hospitalizations

  6. NYHA functional class [ Time Frame: 20 weeks ]
    The range of the NYHA functional class is I to IV, where I is the patient with the best functional class and IV is a patient with the worst functional class.

Other Outcome Measures:
  1. Estimated glomerular filtration rate [ Time Frame: 20 weeks ]
    Glomerular filtration rate will be assessed with the CKD-EPI equation.
