Brief summary

Acute congestion is common in patients with heart failure (HF) and is associated with impaired renal function, reduced quality of life, hospital readmissions, and mortality. Current guidelines recommend optimal decongestion using diuretic therapy, mainly loop diuretics. Although acetazolamide has recently demonstrated efficacy in hospitalized patients, its role in ambulatory patients managed through remote telemonitoring remains to be established. This study aims to evaluate the efficacy of oral acetazolamide added to conventional treatment for decongesting ambulatory HF patients during congestive decompensations. ACHIEVE is a Phase III multicenter, prospective, interventional, randomized, controlled, open-label superiority trial evaluating the efficacy of oral acetazolamide added to conventional treatment for decongestion in ambulatory patients with heart failure during congestive decompensation monitored by remote telemonitoring. The primary objective is to assess, at Day 5, whether acetazolamide added to conventional treatment improves decongestion compared with standard treatment alone. Secondary objectives include evaluating efficacy, safety, and health economic outcomes, including quality of life, dyspnea, biological markers, unplanned consultations, hospitalizations, mortality, and hospital medical costs.

Interventions

DRUGAcetazolamide

Oral acetazolamide initiated at 500 mg (2 tablets) on Day 0. The dose may be adjusted every 48 hours according to the participant's clinical status until Day 5, if necessary.

DRUGFurosemide

Standard treatment with loop diuretics (furosemide) administered for up to 5 days according to standard clinical practice.

Intervention model description

This multicenter, prospective, randomized, controlled, open-label, superiority Phase III trial compares two parallel groups: standard decongestion with loop diuretics (control group) versus standard decongestion plus oral acetazolamide (experimental group) in ambulatory patients with decompensated heart failure monitored by remote telemonitoring.
