Résumé
Importance: Sodium-glucose cotransporter 2 inhibitors are known to reduce heart failure events and slow progression of kidney disease among patients with heart failure and a reduced ejection fraction. Objective: To determine the effect of dapagliflozin on cardiovascular and kidney outcomes and the influence of baseline kidney disease among patients with heart failure and a mildly reduced or preserved ejection fraction enrolled in the Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure (DELIVER) trial. Design, Setting, and Participants: This was a prespecified analysis conducted from July 1 to September 18, 2022 of the DELIVER randomized clinical trial. This was an international, multicenter trial including patients with ejection fraction greater than 40% and estimated glomerular filtration rate (eGFR) of 25 mL/min/1.73 m2 or higher. Interventions: Dapagliflozin, 10 mg, per day or placebo. Main Outcomes and Measures: Outcomes assessed were whether baseline kidney function modified the treatment effect on the primary outcome (cardiovascular death or worsening heart failure). Also examined was the treatment effect on the prespecified outcomes of eGFR slope and a post hoc composite kidney outcome (first ≥50% decline in eGFR from baseline; first eGFR <15 mL/min/1.73 m2; end-stage kidney disease; death from kidney causes). Results: A total of 6262 patients (mean [SD] age, 72 [10] years; 3516 male [56%]) had mean (SD) eGFR measurements available: 61 (19) mL/min/1.73 m2; 3070 patients (49%) had an eGFR less than 60 mL/min/1.73 m2. The effect of dapagliflozin on the primary outcome was not influenced by baseline eGFR category (eGFR ≥60 mL/min/1.73 m2: hazard ratio [HR], 0.84; 95% CI, 0.70-1.00; eGFR 45-<60 mL/min/1.73 m2: HR, 0.68; 95% CI, 0.54-0.87; eGFR <45 mL/min/1.73 m2: HR, 0.93; 95% CI, 0.76-1.14; P for interaction = .16). Over a median (IQR) follow-up of 2.3 (1.7-2.8) years, the overall incidence rate of the kidney composite outcome was low (1.1 events per 100 patient-years) and was not affected by treatment with dapagliflozin (HR, 1.08; 95% CI, 0.79-1.49). However, dapagliflozin attenuated the decline in eGFR from baseline (difference, 0.5; 95% CI, 0.1-0.9 mL/min/1.73 m2 per year; P = .01) and from month 1 to 36 (difference, 1.4; 95% CI, 1.0-1.8) mL/min/1.73 m2 per year; P < .001). Conclusions and Relevance: Results of this prespecified analysis showed that baseline kidney function did not modify the benefit of dapagliflozin in patients with heart failure and a mildly reduced or preserved ejection fraction. Dapagliflozin did not significantly reduce the frequency of the kidney composite outcome, although the overall event rate was low. However, dapagliflozin slowed the rate of decline in eGFR compared with placebo. Trial Registration: ClinicalTrials.gov Identifier: NCT03619213.
