Trial Title: Acetazolamide in Decompensated Heart Failure With Volume OveRload (ADVOR)

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: TRIPLE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Signed written informed consent must be obtained before any study assessment is performed~* Male or female patients 18 years of age or older~* An elective or emergency hospital admission with clinical diagnosis of decompensated HF with at least one clinical sign of volume overload (e.g. oedema (score 2 or more), ascites confirmed by echography or pleural effusion confirmed by chest X-ray or echography)~* Maintenance therapy with oral loop diuretics at a dose of at least 1 mg bumetanide or an equivalent dose for at least 1 month before hospital admission (Conversion: 1 mg bumetanide = 40 mg furosemide = 20 mg torsemide)~* Plasma NT-proBNP levels \>1000 ng/mL or BNP levels \>250 ng/mL at the time of screening.~* Assessed LVEF by any imaging technique; i.e. echocardiography, catheterization, nuclear scan or magnetic resonance imaging within 12 months of inclusion~Exclusion Criteria:~* Concurrent diagnosis of an acute coronary syndrome defined as typical chest pain in addition to a troponin rise above the 99th percentile and/or electrocardiographic changes suggestive of cardiac ischemia~* History of congenital heart disease requiring surgical correction~* History of a cardiac transplantation and/or ventricular assist device~* Systolic blood pressure \<90 mmHg or mean arterial pressure \<65 mmHg at the moment of admission~* Expected use of intravenous inotropes, vasopressors or nitroprusside during the study. Use of nitrates is allowed only if the patient's systolic blood pressure is \>140 mmHg~* Estimated glomerular filtration rate \<20 mL/min/1.73m² at screening~* Use of renal replacement therapy or ultrafiltration at any time before study inclusion~* Treatment with acetazolamide during the index hospitalization and prior to randomization~* Exposure to nephrotoxic agents (i.e. contrast dye) anticipated within the next 3 days~* Use of any non-protocol defined diuretic agent with the exception of mineralocorticoid receptor antagonists. Thiazides, metolazone, indapamide and amiloride should be stopped upon study inclusion. If patient is taking a combination drug including a thiazide-type diuretic, the thiazide-type diuretic should be stopped~* Current use of sodium-glucose transporter-2 inhibitors~* Subjects who are pregnant or breastfeeding

Study Arms:
- high-dose loop diuretics+placebo (Type: PLACEBO_COMPARATOR): * At the moment of randomization (day 1), oral loop diuretics are stopped and the patient receives IV loop diuretics at a dose equal to the double of his oral daily maintenance dose + 500 mg IV bolus of placebo.~* If the patient still have signs of volume overload the next mornings (day 2 and day 3), the patient will receive IV loop diuretics at a dose equal to the oral daily maintenance dose + 500 mg IV bolus of placebo. It the patient has no sign of volume overload at these time points, the study treatment will be stopped.
- high-dose loop diuretics+acetazolamide (Type: EXPERIMENTAL): * At the moment of randomization (day 1), oral loop diuretics are stopped and the patient receives IV loop diuretics at a dose equal to the double of his oral daily maintenance dose + 500 mg IV bolus of acetazolamide.~* If the patient still have signs of volume overload the next mornings (day 2 and day 3), the patient will receive IV loop diuretics at a dose equal to the oral daily maintenance dose + 500 mg IV bolus of acetazolamide. It the patient has no sign of volume overload at these time points, the study treatment will be stopped.

Based on this trial design, predict the completion outcome and termination type (if applicable).
