NCT03720288

Brief Summary

Introduction: Recent studies have suggested that the use of acetazolamide may assist in the vol- ume management of patients with decompensated heart failure (HF). However, prospective and randomized comparison in patients with HF and optimized diuretic therapy has not been described. Objective: The aim of this study was to evaluate the effectiveness and safety of the use of acetazolamide versus placebo in volume control in patients with decompensated HF. Methodology: For this, a unicentric, randomized, double blind and prospective study will be performed in a comparative manner. Hospital data (test results, medical outcomes, drug dose, complications) of patients will be analyzed for safety and effectiveness. Expected results: The use of acetazolamide as an adjuvant treatment is superior to the standard strategy for volume control in patients with decompensated HF.

Study Arms (2)

Acetazolamide

EXPERIMENTAL

All patients will receive an initial dose of intravenous furosemide of 1mg / kg, subsequently descaled to 0.5mg / kg of 6 / 6h, associated with oral hydrochlorothiazide 25mg / day and spironolactone 25mg / day orally. When the patient is randomized to the acetazolamide group, he / she will start using the adjuvant medication as acetazolamide drug capsule at the daily dose of 250 mg / day (oral) during the first three days of treatment.

Drug: Acetazolamide

Placebo

EXPERIMENTAL

All patients will receive an initial dose of intravenous furosemide of 1mg / kg, subsequently descaled to 0.5mg / kg of 6 / 6h, associated with oral hydrochlorothiazide 25mg / day and spironolactone 25mg / day orally. When the patient is randomized to the placebo group, he / she will start using the placebo drug capsule during the first three days of treatment.

Drug: Placebo
