•Evidence of AMI either ST segment elevation or Non-ST segment elevation MI by biomarkers of cardiac injury and symptoms. Cut-off for creatine phosphokinase (CPK) \>2 times and troponin \>3 times the upper limit for the lab. Only Patients who undergo coronary revascularization (PCI, CABG) will be enrolled.
•LVEF \< 45%. (Based on 10 points SD in echo measurements for LVEF)
•NYHA functional class I-III
•Patients aged 18 or above, both genders.

•Patients with spontaneous or induced sustained ventricular tachycardia after 48-72 hours. (30 beats or more at 120 bpm or greater)
•Absolute contraindications to undergo CMRI (Renal failure with GFR\<30% or ICD/PPM)
•Antiarrhythmic medications for ventricular arrhythmias (other than beta-blockers)
•Severe non-ischemic cardiac pathology. (e.g., ARVD, HCM, severe, restrictive cardiomyopathies (amiloydosis/sarcoidosis). We are aware that non-ischemic and ischemic cardiomyopathy may co-exist. However, these cardiomyopathies convey further arrhythmic risk and diffuse LV impairment.
•Unwilling or unable to provide informed consent
•Life expectancy less than 1 year.
•Current drug or alcohol abuse.
•Pregnancy
•Claustrophobia
•Patients who are enrolled in other trials with a treatment arm. (Patients enrolled in diagnostic trials can be included).
•Difficulty to attend the follow-up schedule due to a history of medical noncompliance, living a distance from the study center, or anticipated nonresidence in the area for the length of time required for follow-up.
