Acetazolamide Versus Dapagliflozin in Acute Decompensated Heart Failure Patients

The goal of this clinical trial is to compare the effectiveness of acetazolamide versus dapagliflozin as an add-on in treating acute decompensated heart failure (ADHF) in adult patients with clinical signs of volume overload requiring intravenous loop diuretics. It will also assess the safety of these drugs when added to standard care. The main questions it aims to answer are: * Does acetazolamide or dapagliflozin lead to a greater reduction in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels? * Which drug results in better loop diuretic efficiency, as measured by weight loss per 40 mg of intravenous furosemide or equivalent? We will compare acetazolamide to dapagliflozin, both added to standard intravenous loop diuretic therapy, to see which is more effective in decongesting patients with ADHF. Participants will: * Take either acetazolamide or dapagliflozin orally every day for 3 days * Receive intravenous loop diuretics as part of standard care * Undergo regular assessments of heart failure symptoms, weight, and laboratory tests * Be followed up until hospital discharge and for 30 days after starting the study
