Safety and Efficacy of Empagliflozin and Diuretic Use in Patients with Heart Failure and Preserved Ejection Fraction

JAMA CardiolPublished

  • Post hoc analysis of the EMPEROR-Preserved randomised trial
  • phase 3
  • double-blind
  • placebo-controlled
  • subgroup analysis by baseline diuretic use and dose

Authors' conclusion

In this study, treatment with empagliflozin was similar regardless of diuretic use or dose. Empagliflozin use was associated with decreased conventional diuretic dosing.

Study context

Population
Patients with class II–IV HF and LVEF >40% (heart failure and preserved ejection fraction (HFpEF)) in EMPEROR-Preservedof 5988 enrolled
Participants
5,815 patients
Comparison
Empagliflozin vs placebo by baseline diuretic status and dose
  • No diureticn = 1,179
  • <40 mgn = 1,725
  • 40 mgn = 1,772
  • >40 mgn = 1,139
Primary endpoint

Outcomes by diuretic dose in placebo

Higher diuretic doses had worse outcomes in placebo
