EMPEROR-Reduced trial
EMPEROR-Preserved trial
The ESC defined types of heart failure
Each type has different characteristics and is managed differently5
EMPEROR-Reduced trial1
The EMPEROR-Reduced trial investigated the efficacy of empagliflozin 10 mg versus placebo, in addition to guideline-directed medical therapy (GDMT), in patients with symptomatic chronic heart failure with reduced ejection fraction (LVEF ≤40%).

Primary outcome of the EMPEROR-Reduced trial
JARDIANCE® demonstrated superiority in reducing the risk of CV death or HHF in HF patients with LVEF ≤40% on top of SoC vs placebo1,11
The EMPEROR-Reduced trial demonstrated that treatment with JARDIANCE® (empagliflozin) reduced the risk of cardiovascular (CV) death or hospitalization for heart failure (HHF) compared to placebo in patients with heart failure and reduced ejection fraction (LVEF ≤40%). The primary composite endpoint showed a 25% relative risk reduction (RRR) and a 5.3% absolute risk reduction (ARR) in CV death or HHF (HR: 0.75; 95% CI: 0.65–0.86; p<0.001). The number needed to treat (NNT) to prevent one primary event over a 16-month period was 20 (95% CI: 13, 37).
Secondary outcome of the EMPEROR-Reduced trial
JARDIANCE® reduced total hospital admissions for heart failure in HF patients with LVEF ≤40% on top of SoC vs placebo1,11
The total number of hospitalisations for heart failure was lower in the JARDIANCE® group than in the placebo group, with 388 events vs 553 events, respectively HR, 0.70; 95% CI, 0.58 to 0.85; p<0.001.
Based on the 30% RRR (8.8% ARR) demonstrated for hospitalisations for heart failure, 12 patients would need to have been treated with JARDIANCE® to prevent one event.
EMPEROR-Preserved trial2
The EMPEROR-Preserved trial investigated the efficacy of empagliflozin 10 mg versus placebo, in addition to background treatment, in patients with symptomatic chronic heart failure with preserved ejection fraction (LVEF >40%).

Efficacy results: EMPEROR-Preserved trial
Primary outcome of EMPEROR-Preserved
JARDIANCE® demonstrated superiority in reducing the risk of CV death or HHF in HF patients with LVEF >40% on top of SoC vs placebo1,11
Subgroup analysis showed efficacy was consistent across the spectrum of LVEF.14 The primary composite outcome occurred in 415 patients (13.8%) in the empagliflozin group and 511 patients (17.1%) in the placebo group (HR 0.79; 95% CI, 0.69–0.90; p<0.001).
With a 21% relative risk reduction (3.3% absolute risk reduction) in CV death or hospitalisation for heart failure (HHF), the number needed to treat (NNT) to prevent one primary event was 31 (95% CI, 20–69).
Secondary composite outcome of EMPEROR-Preserved
JARDIANCE® demonstrated superiority in reducing the risk of first or recurrent HHF in HF patients with LVEF >40% vs placebo.2
The total number of HHF was lower in the JARDIANCE® group than in the placebo group, with 407 events vs 541 events, respectively (HR, 0.73; 95% CI, 0.61 to 0.88; p<0.001).
Based on the 27% RRR (4.5% ARR) demonstrated for HHF, 22 patients would need to have been treated with JARDIANCE® to prevent one event.
