Authors' conclusion

The EMPULSE trial findings illustrate how deaths, clinical events and patient-reported outcomes can be integrated into a win ratio analysis strategy that yields clinically meaningful findings of patient benefit.

Study context

Population
Patients with acute heart failure (HF) after initial stabilization
Participants
530 patients
Comparison
Empagliflozin vs placebo
Primary endpoint
Hierarchical composite of:
  1. Death
  2. Number of HF events
  3. Time to first HF event
  4. ≥5-point difference in KCCQ total symptom score change
(stratified win ratio)
Follow-up
90 days

Primary result

As reported in the abstract

Hierarchical composite:
  1. Death
  2. Number of HF events
  3. Time to first HF event
  4. ≥5-point difference in KCCQ total symptom score change

Unstratified win ratio

1.38

95% CI 1.11–1.71

P = 0.0036

Empagliflozinvs Placebo
unstratified win ratio 1.38 (95% CI 1.11–1.71); P = 0.0036
Win ratio, de novo acute HF
1.29
Win ratio, decompensated chronic HF
1.39

Further findings

Win ratio by stratum (de novo acute HF; decompensated chronic HF) · 90 days

De novo acute HF win ratio
1.29
Decompensated chronic HF win ratio
1.39

Alternative hierarchy constructions

Including both number of HF events and time to first HF event appears an unnecessary complication
