Pilot trial to determine diagnostic efficacy of post-reperfusion troponin kinetics in detection of hemorrhagic myocardial infarction

Inclusion Criteria:

1. Age ≥ 18 years
2. Index STEMI
3. Coronary angiogram with PCI to occur irrespective of the onset of the symptoms.
4. Ability to provide informed consent for themselves

Exclusion Criteria:

1. History of prior myocardial infarction,
2. Cardiogenic shock,
3. Patients who present with current cardiac arrest
4. Any contraindication to cardiac CMR (claustrophobia, pacemaker or cardiac defibrillator, known allergy to gadolinium),
5. Presence of permanent atrial fibrillation,
6. Unconscious patient,
7. Severe renal insufficiency (creatinine clearance ≤ 30 ml/min/m2 or renal replacement therapy),
8. Women who are pregnant or breastfeeding. Women of reproductive potential must have a negative pregnancy test.

The study population consists of individuals aged 18 to 80 who have been diagnosed with acute ST-elevation myocardial infarction (STEMI) and are scheduled for emergency percutaneous coronary intervention (PCI).
