Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
No
Sampling Method:
Non-Probability Sample
The study population consists of individuals aged 18 to 75 who have been diagnosed with acute ST-elevation myocardial infarction (STEMI) presenting to ER within 12 hours of symptom onset and are scheduled for emergency percutaneous coronary intervention (PCI).
Inclusion Criteria:
Age ≥ 18 years
Index Anterior wall STEMI, based on:
Symptoms of myocardial ischemia (such as chest pain, shortness of breath, jaw pain, arm pain, diaphoresis, or any anginal equivalent) and
ECG criteria: New or presumed new ST-segment elevation at the J point in two or more contiguous leads with the cut off points ≥0.2 mV in leads V1, V2, V3 or V4 and ≥0.1 mV in other leads OR new left bundle branch block (LBBB)
Coronary angiogram with evidence of total or subtotal occlusion of the left anterior descending coronary artery (LAD)
Coronary angiogram with PCI to occur irrespective of the onset of the symptoms.
Ability to provide informed consent for themselves
Exclusion Criteria:
History of prior myocardial infarction,
Cardiogenic shock,
Patients who present with current cardiac arrest
Any contraindication to cardiac CMR (claustrophobia, pacemaker or cardiac defibrillator, known allergy to gadolinium),
Presence of permanent atrial fibrillation,
Unconscious patient,
Severe renal insufficiency (creatinine clearance ≤ 30 ml/min/m2 or renal replacement therapy),
Women who are pregnant or breastfeeding. Women of reproductive potential must have a negative pregnancy test.
