Abstract
Background: Anaemia is common in heart failure and associated with worse outcomes. We examined the effect of dapagliflozin on correction of anaemia in patients with heart failure and reduced ejection fraction (HFrEF) in DAPA‐HF. We also analyzed the effect of dapagliflozin on outcomes, according to anaemia status at baseline. Methods: Anaemia was defined at baseline as a haematocrit <39% in men and <36% in women. Resolution of anaemia was defined as two consecutive haematocrit measurements above these thresholds at any time during follow‐up. The primary outcome was a composite of worsening HF (hospitalization or urgent visit requiring intravenous therapy) or cardiovascular death.. Findings: Of the 4744 patients randomized in DAPA‐HF, 4691 had a haematocrit available at baseline, of which 1032 were anaemic (22.0%). The rate of the primary outcome was higher in patients with anaemia (16.1 per 100 person‐years) compared with those without (12.9 per 100 person‐years). Anaemia was corrected in 62.2% of patients in the dapagliflozin group, compared with 41.1% of patients in the placebo group. The effect of dapagliflozin on the primary outcome was consistent in anaemic compared with non‐anaemic patients (HR 0.68 [95%CI 0.52‐0.88] versus 0.76 [0.65‐0.89]; P‐interaction=0.44). Similar findings were observed for cardiovascular death, HF hospitalization, and all‐cause mortality. Patients with resolution of anaemia had better outcomes than those in which anaemia persisted. Conclusion: Patients with anaemia had worse outcomes in DAPA‐HF. Dapagliflozin corrected anaemia more often than placebo and improved outcomes, irrespective of anaemia status at baseline.
