This is a study in adults who are in hospital for acute heart failure. The purpose of this study is to find out whether starting to take a medicine called empagliflozin soon after first being treated in hospital helps people with acute heart failure. Participants are in the study for about 3 months. At the beginning, participants are still in hospital. Later, they visit the hospital about 3 times and get 1 phone call. Participants are put into 2 groups by chance. One group takes 1 empagliflozin tablet a day. The other group takes 1 placebo tablet a day. Placebo tablets look like empagliflozin tablets but do not contain any medicine. Empagliflozin belongs to a class of medicines known as SGLT-2 inhibitors. It is used to treat type 2 diabetes. During the study, the doctors check whether participants have additional heart failure events like needing to go to the hospital again because of heart failure. The participants answer questions about how their heart failure affects their life. We then compare the results between the empagliflozin and placebo groups. The doctors also regularly check the general health of the participants.

Open to people ages 18 years and up

  • Currently hospitalised for the primary diagnosis of acute heart failure (de novo or decompensated chronic HF), regardless of ejection fraction (EF). Patients with a diagnosis of hospitalized heart failure must have HF symptoms at the time of hospital admission
  • Evidence of left ventricular ejection fraction (LVEF, either reduced or preserved EF) as per local reading preferably measured during current hospitalisation or in the 12 months prior to randomisation
  • Patients must be randomised after at least 24 hours and no later than 5 days after admission, as early as possible after stabilization and while still in hospital
  • Patients must fulfil the following stabilisation criteria (while in the hospital):
  • SBP ≥100mm Hg and no symptoms of hypotension in the preceding 6 hours,
  • no increase in i.v. diuretic dose for 6 hours prior to randomisation,
  • no i.v. vasodilators including nitrates within the last 6 hours prior to randomisation
  • no i.v. inotropic drugs for 24 hours prior to randomisation.
  • Elevated NT-proBNP ≥ 1600pg/mL or BNP ≥400 pg/mL according to the local lab, for patients without atrial fibrillation (AF); or elevated NT-proBNP ≥ 2400pg/mL or BNP ≥600 pg/mL for patients with AF, measured during the current hospitalization or in the 72 hours prior to hospital admission,. For patients treated with an angiotensin receptor neprilysin inhibitor (ARNI) in the previous 4 weeks prior to randomisation, only NT-proBNP values should be used
  • HF episode leading to hospitalisation must have been treated with a minimum single dose of 40 mg of i.v. furosemide (or equivalent i.v. loop diuretic defined as 20 mg of torasemide or 1 mg of bumetanide)

  • Current hospitalisation for acute heart failure primarily triggered by pulmonary embolism, cerebrovascular accident, or acute myocardial infarction (AMI)
  • Current hospitalisation for acute heart failure not caused primarily by intravascular volume overload;
  • Below interventions in the past 30 days prior to randomisation or planned during the study:
  • Major cardiac surgery, or TAVI (Transcatheter Aortic Valve Implantation), or PCI, or Mitraclip

  • Haemodynamically significant (severe) uncorrected primary cardiac valvular disease planned for surgery or intervention during the course of the study (note: secondary mitral regurgitation or tricuspid regurgitation due to dilated cardiomyopathy is not excluded unless planned for surgery or intervention during the course of the study)
