BACKGROUND: Patients recently hospitalized for heart failure (HF) often have unstable hemodynamics and experience worsening renal failure, and are at elevated risk for recurrent HF events. In DELIVER, dapagliflozin reduced HF events or cardiovascular death including among patients who were hospitalized or recently hospitalized.

METHODS: We examined the effects of dapagliflozin vs. placebo on eGFR slope (acute and chronic), 1 month change in systolic blood pressure (SBP), and the occurrence of serious hypovolemic or renal adverse events in patients with and without HF hospitalization within 30 days of randomization.

RESULTS: The 654 (90 randomized during hospitalization, 147 1-7 days post-discharge and 417 8-30 days post-discharge) recently hospitalized patients had lower baseline eGFR compared with those without recent HF hospitalization median[IQR] of 55 [43,71] vs 60 [47,75] ml/min/1.73m2 ). Dapagliflozin consistently reduced the risk of all-cause (Pinteraction =0.20), cardiac-related (Pinteraction =0.75), and HF-specific (Pinteraction =0.90) hospitalizations, irrespective of recent HF hospitalization. In those recently hospitalized, acute placebo-corrected eGFR reductions with dapagliflozin were modest and similar to patients without recent hospitalization (-2.0 [-4.1,+0.1] vs. -3.4 [-3.9,-2.9] ml/min/1.73m2 , Pinteraction =0.12). Dapagliflozin's effect to slow chronic eGFR decline was similar regardless of recent hospitalization (Pinteraction =0.57). Dapagliflozin had a minimal effect on 1-month SBP and to a similar degree in patients with and without recent hospitalization (-1.3 vs.-1.8 mmHg, Pinteraction =0.64). There was no treatment-related excess in renal or hypovolemic serious AE, irrespective of recent HF hospitalization.

CONCLUSION: In patients recently hospitalized with HF, initiation of dapagliflozin had minimal effects on BP and did not increase renal or hypovolemic serious AEs, yet afforded long-term cardiovascular and kidney protective effects. These data suggest that the benefit to risk ratio favours initiation of dapagliflozin among stabilized patients hospitalized or recently hospitalized for HF. This article is protected by copyright.
