EMPEROR-Pooled: effect of empagliflozin on serious adverse renal outcomes in chronic heart failure – a prospective alpha-protected, Individual patient-level pooled analysis

Presented at the ESC congress 2021 by: Milton Packer, MD - Dallas, TX, USA

Introduction and methods

EMPEROR-Pooled was a prospectively-designed, patient-level pooled analysis of the data from EMPEROR-Reduced and EMPEROR-Preserved. Both trials investigated the effects of the SGLT2 inhibitor empagliflozin versus placebo in patients with established HF. The primary composite outcome of both trials was time to first event of adjudicated CV death or adjudicated HF hospitalization. EMPEROR-Reduced and EMPEROR-Preserved had nearly identical protocols and were caried out in a similar time period. The trials were primarily distinguished by the LVEF cutoff of 40%: Patients enrolled in EMPEROR-Reduced had HF and an LVEF of ≤40%, while patients enrolled in EMPEROR-Preserved had HF and an LVEF of >40%.

EMPEROR-Pooled assessed the effects of empagliflozin vs placebo on HF hospitalization and major renal outcomes in patients with HF across the entire spectrum of LVEF. A total of 9718 patients were included in the analysis and EMPEROR-Pooled had its own statistical plan, which was defined at the start of the program.

Main results


The EMPEROR-Pooled analysis showed that the SGLT2 inhibitor empagliflozin, compared to placebo, on top of standard of care reduced HF hospitalizations by approximately 30% in patients with HF across a broad range of LVEF from <25% to <65%. Empagliflozin reduced the risk of major renal outcomes in HF patients with LVEF <50%, but not in patients with higher LVEF.
