Presentation Transcript

  1. EMPHASIS-HFExtended Follow-up Background • EMPHASIS-HF showed that eplerenone, compared with placebo, significantly reduced the risk of the composite of CV death and hospitalization for HF in patients with chronic systolic NYHA class II HF • Enrollment was stopped prematurely when an overwhelming benefit on the primary endpoint was observed in the secondary interim analysis • Investigators continued to follow a subgroup of patients (n=1597) for 10 months on blinded therapy, resulting in a mean follow-up of 25 months • Extended follow-up produced three sets of new data: • Safety and efficacy results of the extended follow-up • Exploratory analysis of recurrent hospitalization • Analyses in five high-risk subgroups (age ≥75 years; LVEF <30%; eGFR <60 mL/min/1.73 m2; diabetes; SBP <123 mm Hg

  2. EMPHASIS-HFExtended Follow-up Key Findings • The primary composite endpoint of CV death or hospitalization for heart failure was reduced with eplerenone compared with placebo • The cumulative number of hospitalizations for heart failure (recurrent event analysis) favored eplerenone • In each of the five subgroups, there were significant reductions with eplerenone in the secondary endpoints of all-cause hospitalization and in hospitalization for heart failure

  4. EMPHASIS-HFExtended Follow-up Conclusions • Eplerenone demonstrated a consistent benefit in the reduction of CV death or hospitalization for HF over continued follow-up and among individual high-risk subgroups • Important reductions were also seen in the secondary endpoints of all-cause hospitalization and in hospitalization for heart failure • Although these results show compelling evidence for efficacy that is consistent with guideline recommendations for this class of medications, there were higher rates of hyperkalemia, and the study protocol required careful monitoring with visits every 4 months. This should be considered when applying these results with eplerenone in clinical practice
