Acetazolamide and Spironolactone to Increase Natriuresis in Congestive Heart Failure

NCT01973335 ↗

RandomizedFactorialTriple-blindTreatment

Summary

This study has two primary objectives: 1. To compare combination therapy with acetazolamide and low-dose loop diuretics versus high-dose loop diuretics (standard of care) in patients with acute decompensated heart failure at high risk for diuretic resistance. 2. To demonstrate the safety and efficacy of upfront therapy with spironolactone in addition to loop diuretic therapy in patients with acute decompensated heart failure at high risk for diuretic resistance.
