Exclusion criteria

Exclusion criteria: 1. Women of childbearing potential 2 . Patients indicated for rescue PCI (i.e. after receiving fibrinolysis) 3. Patients presenting with cardiogenic shock defined as either systolic blood pressure (SBP) 90 mmHg or more persisting despite fluid challenge or inotropes/vasopressors use to maintain SBP more than 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) 6.
