Post Cond No Reflow
After having shown that postconditioning allowed a significant 36% reduction of infarct size as assessed by blood levels of myocardial enzymes in acute myocardial patients, the investigators objective is to assess the effect of postconditioning in acute myocardial infarction (AMI) patients on microvascular obstruction lesions defined by cardiac MRI images.

- Extent of the area of microvascular obstruction [ Time Frame: 5 days ] [ Designated as safety issue: Yes ]Extent of the area of microvascular obstruction defined on post-gadolinium CMR images realized 48-72 hours after admission in each group
- Size of the myocardial infarction [ Time Frame: 5 days ] [ Designated as safety issue: Yes ]Size of the myocardial infarction defined on post-gadolinium CMR images realized 48-72 hours after admission in each group.
