Primary Outcome Measures :
  1. Infarct size evaluated by delayed enhancement-magnetic resonance imaging [ Time Frame: between day 3 and day 5 after acute myocardial infarction (AMI) ]

Secondary Outcome Measures :
  1. Infarct size/area at risk ratio evaluated by MRI [ Time Frame: between day 3 and day 5 after AMI ]
  2. release of creatine kinase (CK) and troponin I (TnI) during reperfusion [ Time Frame: during the first 72 hours after reperfusion ]
    The Area Under the Curve of CK and TnI during reperfusion

  3. the Thrombolysis In Myocardial Infarction (TIMI) myocardial Blush after reperfusion [ Time Frame: at day 0 ]
  4. ST segment resolution after reperfusion [ Time Frame: during the first 24 hours after reperfusion ]
  5. Left Ventricular Ejection Fraction measured by echocardiography [ Time Frame: at day 1 and day 6 ]
  6. Infarct size measurement by delayed enhancement-magnetic resonance imaging [ Time Frame: 1 year ]
