Empagliflozin reduces HF hospitalization and CV death regardless of baseline diuretic doses
Empagliflozin reduces HF hospitalization and CV death regardless of baseline diuretic doses suggests a new study published in the JACC: Heart Failure.
The EMPEROR-Reduced (EMPagliflozin outcome trial in Patients With chrOnic Heart Failure With Reduced Ejection Fraction) trial established the efficacy of empagliflozin in reducing heart failure (HF) outcomes among patients with heart failure with reduced ejection fraction (HFrEF).
The authors examined the outcomes of EMPEROR-Reduced as a function of background diuretic therapy.
The EMPEROR-Reduced trial was a double-blind, randomized controlled trial of placebo vs empagliflozin 10 mg among 3,730 HFrEF patients. Herein, the population was stratified into 4 groups: no diuretic and diuretic dose equivalent to furosemide <40, 40, and >40 mg daily at baseline.
Results
A total of 3,656 patients from the EMPEROR-Reduced trial were available for analysis. Of those patients, 482 (13.2%) were receiving no diuretic therapy, and 731 (20.0%), 1,411 (38.6%), and 1,032 (28.2%) were receiving <40 mg, 40 mg, and >40 mg, respectively. The efficacy of empagliflozin on the primary outcome (time to first event of hospitalization for HF or cardiovascular [CV] death) was consistent regardless of background diuretic therapy (>40 mg: HR: 0.88 [95% CI: 0.71-1.10]; 40 mg: HR: 0.65 [95% CI: 0.51-0.82]; <40 mg: HR: 0.65 [95% CI: 0.46-0.92]); no diuretic agents: HR: 0.78 [95% CI: 0.47-1.29]; Ptrend test = 0.192). Baseline diuretic doses did not influence the effect of empagliflozin on body weight, systolic blood pressure, NT-proBNP, or hematocrit at 52 weeks. The safety profile of empagliflozin vs placebo was unaffected by baseline diuretic dose; however, independently of treatment allocation, total rates of adverse events were higher among patients with higher baseline doses of diuretic agents.
Empagliflozin exhibits a consistent effect on time to CV death or HF hospitalization and an unaltered safety profile regardless of baseline diuretic therapy. (EMPagliflozin outcome trial in Patients With chronic heart Failure With Reduced Ejection Fraction
