Dapagliflozin Improves Heart Failure Symptoms and Physical Limitations Across the Full Range of Ejection Fraction: Pooled Patient-Level Analysis From DEFINE-HF and PRESERVED-HF Trials

Circ Heart FailPublished Pooled patient-level analysis of the DEFINE-HF and PRESERVED-HF randomised trials

Authors' conclusion

In patients with HF, dapagliflozin significantly improves symptoms and physical limitations after 12 weeks of treatment, with consistent and clinically meaningful benefits across the full range of EF.

Further pooled results

KCCQ-CSS responder analyses (deterioration; small, moderate, large improvements)

Fewer dapagliflozin-treated patients had deterioration and more had small, moderate and large KCCQ-CSS improvements vs placebo, consistent regardless of EF
  • All interaction P values nonsignificant
