Key exclusion criteria

3. Patients presenting with cardiogenic shock defined as either systolic blood pressure (SBP) =90 mmHg persisting despite fluid challenge or inotropes/vasopressors use to maintain SBP >90 mmHg.
4. Known history of symptomatic heart failure (HF) with left ventricular systolic dysfunction (i.e. HFrEF) based on verbal medical history as reported by a trial participant or authorised representative
5. Known history of myocardial infarction (MI) with the exception of the index event (based on verbal medical history as reported by a trial participant or authorised representative)
