NCT ID NCT03892148

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a step-by-step plan for using diuretics (water pills) is better and safer than usual care for people hospitalized with worsening chronic heart failure. The trial involved 299 adults and compared a structured protocol using furosemide and hydrochlorothiazide against standard non-protocolized practice. Researchers measured changes in kidney function and weight to see if the protocol reduced complications like kidney injury.
