OBJECTIVES: The study sought to investigate the safety and efficacy of eplerenone in patients at high risk for hyperkalemia or worsening renal function (WRF) in EMPHASIS-HF, a trial that enrolled patients at least 55 years old with heart failure and reduced ejection fraction (HF-REF), in New York Heart Association (NYHA) functional class II and with an estimated glomerular filtration rate (eGFR) >30 ml/min/1.73 m(2) and serum potassium <5.0 mmol/l. Patients were receiving optimal therapy and most had been hospitalized for a cardiovascular reason within 180 days of inclusion. BACKGROUND: Underuse of eplerenone in patients with HF-REF may be due to fear of inducing hyperkalemia or WRF in high-risk patients. METHODS: This was a pre-specified analysis of subgroups of patients at high risk of hyperkalemia or WRF (patients ≥ 75 years of age, with diabetes, with eGFR <60 ml/min/1.73 m(2), and with systolic blood pressure < median of 123 mm Hg), examining the major safety measures (potassium >5.5, >6.0, and <3.5 mmol/l; hyperkalemia leading to study-drug discontinuation or hospitalization; and hospitalization for WRF) as well as the primary outcome (hospitalization for HF or cardiovascular mortality). RESULTS: In all high-risk subgroups, patients treated with eplerenone had an increased risk of potassium >5.5 mmol/l but not of potassium >6.0 mmol/l, and of hospitalization for hyperkalemia or discontinuation of study medication due to adverse events. Eplerenone was effective in reducing the primary composite endpoint in all subgroups. CONCLUSIONS: In patients with chronic HF-REF, in NYHA functional class II, and meeting specific inclusion and exclusion criteria, including an eGFR >30 ml/min/1.73 m(2) and potassium <5.0 mmol/l, eplerenone was both efficacious and safe when carefully monitored, even in subgroups at high risk of developing hyperkalemia or WRF.
