Natriuresis With Acetazolamide or SGLT2 Inhibitors Added to Intravenous Loop Diuretics in Decompensated Heart Failure (GLIDE-DHF)

5 de noviembre de 2026 actualizado por: Universidade do Porto

Natriuresis in Decompensated Heart Failure Patients Treated With Intravenous Loop Diuretics Alone or in Combination With an SGLT2 Inhibitor or Acetazolamide: a Single-Center, Prospective, Open-Label, Non-Randomized, Controlled Interventional Study (GLiflozin or AcetazolamIDE on Top of Loop Diuretics in Decompensated Heart Failure)

The GLIDE-DHF study compares the natriuretic effect of adding acetazolamide or a sodium-glucose co-transporter 2 inhibitor (SGLT2i) to intravenous loop diuretics, versus intravenous loop diuretics alone, in patients admitted to the emergency department with acute decompensated heart failure. Natriuresis is assessed by spot urinary sodium concentration measured 6 hours after the first study treatment. The study also evaluates changes in urinary and serum electrolytes, kidney function, blood pressure, clinical congestion and safety during the first 3 days of treatment.
