Editorial: New Decongestion Strategies in an Evolving Heart Failure Landscape.

Question and Methods: RCT comparing acetazolamide versus placebo on rate of decongestion using loop diuretics in hospitalized patients with acute decompensated heart failure.
Findings: Higher rate of decongestion with acetazolamide versus placebo [108/256 (42.2%) vs 79/259 (30.5%); RR 1.46 (95% CI 1.17-1.82)] with no increased adverse events.
Limitations: Limited applicability to emergency practice; not generalizable to patients with new heart failure or taking SGLT-2 inhibitors.

Interpretation: Acetazolamide added to loop diuretics may increase rate of decongestion for patients admitted with acute decompensated heart failure, but has limited utility in emergency practice.
