Abstract
BACKGROUND:Mineralocorticoid receptor antagonists (MRAs) and sodium glucose co-transporter 2 inhibitors favorably influence the clinical course of patients with heart failure and reduced ejection fraction. OBJECTIVES: This study sought to study the mutual influence of empagliflozin and MRAs in EMPEROR-Reduced (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Reduced Ejection Fraction). METHODS: Secondary analysis that compared the effects of empagliflozin versus placebo in 3,730 patients with heart failure and a reduced ejection fraction, of whom 71% used MRAs at randomization. RESULTS: The effects of empagliflozin on the primary endpoint, on most efficacy endpoints, and on safety were similar in patients receiving or not receiving an MRA (interaction p > 0.20). For cardiovascular death, the hazard ratios for the effect of empagliflozin versus placebo were 0.82 (95% confidence interval [CI]: 0.65 to 1.05) in MRA users and 1.19 (95% CI: 0.82 to 1.71) in MRA nonusers (interaction p = 0.10); a similar pattern was seen for all-cause mortality (interaction p = 0.098). Among MRA nonusers at baseline, patients in the empagliflozin group were 35% less likely than those in the placebo group to initiate treatment with an MRA following randomization (hazard ratio: 0.65; 95% CI: 0.49 to 0.85). Among MRA users at baseline, patients in the empagliflozin group were 22% less likely than those in the placebo group to discontinue treatment with an MRA following randomization (hazard ratio: 0.78; 95% CI: 0.64 to 0.96). Severe hyperkalemia was less common in the empagliflozin group. CONCLUSIONS: In EMPEROR-Reduced, the use of MRAs did not influence the effect of empagliflozin to reduce adverse heart failure and renal outcomes. Treatment with empagliflozin was associated with less discontinuation of MRAs.
