Detailed Description
This study aim at assessing the effect of two levels of dietary sodium intake during seven days in hospitalized patients with Acute Decompensated Heart Failure. It is a prospective cohort, randomized, with blinded intervention groups: low sodium diet (the patients will receive 3 g/day of dietary sodium intake), and normal sodium diet (patients will receive 7 g/day of dietary sodium intake). Besides that, both groups will be submitted to a fluid intake limited to 1000 ml/day.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Other: Low sodium diet 22 patients were randomized to receive 3 g/day of dietary sodium chloride and a limit of fluid intake of 1000 ml/day. |
Other: Low sodium diet
Patients received low sodium diet (3g of sodium chloride/day) and a limit of fluid intake of 1000 ml/day.
|
| Other: Normal sodium diet 22 patients were randomized to receive 7 g/day of dietary sodium chloride and a limit of fluid intake of 1000 ml/day. |
Other: Normal sodium diet
Patients received normal sodium diet (7g of sodium chloride/day) and a limit of fluid intake of 1000 ml/day.

Outcome Measures
Primary Outcome Measures
- Serum sodium level at day 7 [7 days]
The difference of the absolute value of serum sodium between the groups in the final evaluation.
Secondary Outcome Measures
- Occurrence of hyponatremia [on day 7]
The detection of serum level of sodium bellow 135 mmol/L
- Change in body weight [7 days]
The difference of the absolute value of body weight between the initial and final values.
- Change in serum levels of NT-proBNP [7 days]
The difference of the absolute value of NT-proBNP between the initial and final values, and between groups.
- Change in systolic, diastolic and mean blood pressure [7 days]
The difference of the absolute value of blood pressure between the initial and final values.
- Change in heart rate [7 days]
The difference of the absolute value of heart rate between the initial and final values.
- Change in serum levels of creatinine [7 days]
The difference of the absolute value of creatinine between the initial and final values.
- Proportion of patients exhibiting worsening renal function (defined as increased serum creatinine> 0,3 mg / dL) [7 days]
- Change in dyspnea sense [7 days]
Using a visual anologic scale, with values between 0 and 10, where the minimum 0 is the greatest lack of air (worse) and the maximum 10 is the complete breath (better)
- Change in well-being sense [7 days]
Using a visual anologic scale, with values between 0 and 10, where the minimum 0 is the worse you ever felt (worse) and the maximum 10 is feel better than already (better)
- Diuretic dosage and other drugs to ADHF during intervention period [7 days]
What drugs will be used and the quantities.
- Rate of hospital readmission [30 days]
- Rate of mortality after discharge [30 days]
