Brief summary
This study is design to assess two levels of dietary sodium intake in the treatment of patients with Acute Decompensated Heart Failure.
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.
Interventions
OTHERLow sodium diet
Patients received low sodium diet (3g of sodium chloride/day) and a limit of fluid intake of 1000 ml/day.
OTHERNormal sodium diet
Patients received normal sodium diet (7g of sodium chloride/day) and a limit of fluid intake of 1000 ml/day.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
| Occurrence of hyponatremia | on day 7 | The detection of serum level of sodium bellow 135 mmol/L |
| 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) |
