入选标准

  • Symptoms and signs consistent with a diagnosis of heart failure (HF)
  • Left ventricular ejection fraction (LVEF) ≥40% by transthoracic echocardiography within the past 12 months
  • Plasma NT-proBNP level ≥125 pg/ml (≥ 600pg/mL if patient has persistent or permanent atrial fibrillation, atrial flutter, or atrial tachycardia)
  • Estimated glomerular filtration rate (eGFR) ≥40 and ≤70ml/min/1.73m2 (by CKD-EPI formula).
  • Baseline serum potassium (sK+) level ≥3.5 and ≤4.8mmol/l.
  • Stable doses of the following medications at baseline for at least 4 weeks prior to randomisation:
  • Angiotensin receptor blocker (ARB) or Angiotensin converting enzyme inhibitor (ACEi) Loop diuretic (up to a 120mg furosemide dose or equivalent

排除标准

  • Patients with documented LVEF <40% at any time (i.e. patients with previously impaired LVEF that has now improved are not permitted).
  • Patients experiencing acute decompensation of heart failure requiring hospital admission or escalation in therapy.
  • Primary cardiomyopathy (e.g. constrictive, restrictive, infiltrative, toxic, hypertrophic, congenital or any primary cardiomyopathy in judgment of Investigator).
  • Hyponatraemia, defined as serum Na+ <135 mmol/L at the time of enrollment.
  • Persistent resting sinus tachycardia >110 bpm or sinus bradycardia <45bpm.
  • Systolic blood pressure (BP) <110mmHg or >180mmHg.
  • Diastolic BP <60 mmHg or >100 mmHg.
  • Patients previously intolerant to MRA (e.g. spironolactone or eplerenone) for any reason.
  • Medical conditions associated with development of hyperkalaemia (e.g. Addison's disease).
  • Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) level ≥2.0 times the upper limit of normal (ULN).
  • Patients who have been taking an MR antagonist within 1 month prior to randomization.
