Main objective

Scope: Efficacy, Safety

To assess at day 5 the effectiveness of acetazolamide added to conventional treatment on decongestion (interventional group) compared to standard treatment (control group) in patients with ambulatory HF previously treated with furosemide (with fraction of left ventricular ejection impaired or not) and monitored by remote monitoring

Secondary objectives 10

  1. To assess the effectiveness of acetazolamide added to conventional treatment in ambulatory HF patients monitored via telemonitoring as compared with conventional treatment on Decongestion during the first 5 days
  2. To assess the effectiveness of acetazolamide added to conventional treatment in ambulatory HF patients monitored via telemonitoring as compared with conventional treatment on diuretic effectiveness on D5
  3. To assess the effectiveness of acetazolamide added to conventional treatment in ambulatory HF patients monitored via telemonitoring as compared with conventional treatment on evolution of NtproBNP between D0 and D5
  4. To assess the effectiveness of acetazolamide added to conventional treatment in ambulatory HF patients monitored via telemonitoring as compared with conventional treatment on quality of life and dyspnea during the first 5 days
  5. To assess the effectiveness of acetazolamide added to conventional treatment in ambulatory HF patients monitored via telemonitoring as compared with conventional treatment on need for emergent/unplanned consultation or hospitalization for acute HF at day 90
  6. Describe clinical (weight, VAS dyspnea, BP, HR, RHF and LHF signs) and biological (NtproBNP) decongestion evolution between D5 and D15 (in percentage)
  7. Describe clinical (weight, VAS dyspnea, BP, HR, RHF and LHF signs) and biological (NtproBNP) decongestion evolution at D15
  8. Evaluation and comparison of the occurrence of complications and adverse effects in the two groups at Day 5 (in particular: hyponatremia, acute renal failure, hypokalemia, metabolic acidosis, arterial hypotension, low cardiac output/cardiogenic shock)
  9. Need for hospitalization for treatment failure or poor tolerance on D5 and D15
  10. Comparison of hospital medical costs at D90 between the two groups studied (Health economic objective)

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Percentage of patients with weight loss > 2kg on connected scale (Remote telemonitoring system) on D5 in each of the two groups (experimental vs control)

Secondary endpoints 9

  1. Percentage of weight variation between D0 and D5
  2. Diuretic effectiveness on D5 calculated by calculating natriuresis corrected by mg of furosemide equivalence from the urinary ionogram performed on D5
  3. Evolution of NtproBNP between D0 and D5
  4. Evolution of the EQ-5D-5L value between D0 and D5
  5. Evolution of the VAS score for dyspnea between D0 and D5
  6. Rate of unplanned/emergency consultation or hospitalization for HF at D90
  7. Rate of deaths from all causes or for HF at D90
  8. Evolution of clinical (weight, VAS dyspnea, BP, HR, RHF and LHF signs) and biological (NtproBNP) between D5 and D15
  9. Evolution of clinical (weight, VAS dyspnea, BP, HR, RHF and LHF signs) and biological (NtproBNP) at D15
