Arm | Intervention/treatment |
---|---|
Experimental: Exenatide
o Exenatide at a dose of 1.5 µg IV over 30 min followed by 1.2 µg/hr IV for 1.5 h (Rate1), followed by 1.9 µg/hr IV* for 22 h (Rate 2) *Once the creatinine clearance is available, if the value is <60 mL/min, the rate at 2 hours will be maintained at Rate 1 for the duration of the infusion. If the value becomes available after the 2-hour point, and the rate has already been changed to Rate 2, the infusion will be titrated back down to Rate 1 if the creatinine clearance is <60 mL/min. If the creatinine clearance is <30 mL/min, the infusion will be discontinued and the patient will otherwise continue with all study procedures. A bolus administration of study medication is initiated preferably prior to reperfusion, or, if not possible, up to 30 minutes after the start of reperfusion to avoid delays in door-to-door balloon times. |

- Antegrade TIMI 0 or 1 prior to PCI in the infarct-related artery
- Age ≥18 years
Exclusion Criteria:
- Symptomatic hypoglycemia (serum glucose <3.3 µmol/L; 60 mg/dl)
- Diabetes mellitus requiring insulin therapy
- Diabetic ketoacidosis
- Coronary anatomy warranting emergent coronary artery bypass graft surgery
- Mechanical complication of STEMI (ventricular septal rupture, free wall rupture, acute severe mitral regurgitation)
- Need for hemodialysis
- Malignancy, HIV, or central nervous system disorder
- Cardiopulmonary resuscitation >15 min and compromised level of consciousness.
- Cardiogenic shock
- Current participation in any research study involving investigational drugs or devices
- Inability to give informed consent
- Inability to safely undergo cMRI (presence of cardiac pacemaker, implanted cardiac defibrillator, aneurysm clips, carotid artery vascular clamp, neurostimulator, implanted drug infusion device, bone growth/fusion stimulator, cochlear, otologic, or ear implant, severe claustrophobia)
- Women of childbearing potential who are known to be pregnant or lactating or who have a positive pregnancy test on admission
- History of pancreatitis
- Known end stage renal failure or known eGFR <30 mL/min
