Real-world effectiveness and safety of torsemide and spironolactone fixed dose combination in Indian heart failure patients (RESTORE-HF study): a prospective, multicenter, observational study.

TL;DR

The RESTORE-HF study demonstrated that the torsemide-spironolactone fixed-dose combination may be associated with a mean body weight reduction of 2.41 kg and may be generally well-tolerated in Indian heart failure patients, with significant symptomatic improvement over 3 weeks in real-world clinical practice.

Key Findings

Torsemide-spironolactone fixed-dose combination significantly reduced mean body weight over 3 weeks in Indian heart failure patients.

  • Mean body weight decreased from 75.54 kg at baseline to 73.13 kg at week 3
  • Mean difference of 2.41 kg reduction (p < 0.0001)
  • 1752 patients were enrolled across 101 sites in India
  • 1520 patients completed the study
  • Patients were followed over 3 weeks from baseline

Improvement in NYHA functional class was observed over 3 weeks from baseline following torsemide-spironolactone FDC treatment.

  • Change in NYHA functional class was a secondary endpoint
  • Improvement was observed over the 3-week follow-up period
  • Study enrolled patients with HF with reduced ejection fraction and signs of congestion
  • Participants were aged 18-75 years

Edema improved over the 3-week study period, with 22.11% of patients achieving no-edema stage.

  • Change in edema was a secondary endpoint
  • Overall, 22.11% of patients achieved no-edema stage by week 3
  • Edema improvement was assessed from baseline to week 3
  • All enrolled patients had signs of congestion at baseline

The torsemide-spironolactone FDC demonstrated a favorable safety profile with very few adverse events reported.

  • Only three mild adverse events related to loose stools were reported
  • No serious adverse events occurred during the study
  • No deaths occurred during the study period
  • Occurrence of adverse events was a secondary endpoint

Over 98% of both physicians and patients rated the torsemide-spironolactone FDC therapy favorably in terms of efficacy and tolerability.

  • Physician and patient assessments of efficacy and tolerability were secondary endpoints
  • More than 98% of physicians rated the therapy favorably
  • More than 98% of patients rated the therapy favorably
  • Assessments were conducted over the 3-week observation period

The study enrolled a predominantly male, middle-aged Indian heart failure population across 101 sites.

  • Of 1841 patients screened, 1752 were enrolled and 1520 completed the study
  • Mean (SD) age of participants was 58.61 (9.45) years
  • 61.05% of participants were male
  • Study was conducted across 101 sites in India
  • Eligible patients were aged 18-75 years with HF with reduced ejection fraction and signs of congestion
