Brief Summary:
Distal embolization can occur during coronary angioplasty performed in the acute phase of myocardial infarction and is associated with poor long-term outcome. We hypothesize that the use of a system allowing thrombus aspiration before angioplasty and stent implantation will limit infarct size and its severity.

Condition or disease Intervention/treatment
Ischemic Heart Disease Acute Myocardial Infarction Device: Export Aspiration System

Detailed Description:
Patients scheduled for emergency angioplasty in the acute phase of a first ST-elevation myocardial infarction will be treated either by thromboaspiration followed by angioplasty or by angioplasty alone. The infarct size and severity will be assessed by ce-MRI and rest Tc99m-mibi gated SPECT performed during initial hospital stay (5th-8th day). A control MRI will be performed at 6-month follow-up to analyse the evolution of left ventricular volumes.

Intervention Details:
    Device: Export Aspiration System
    Patients scheduled for emergency angioplasty

Primary Outcome Measures :
  1. Infarct size and severity assessed by ce-MRI and rest Tc99m-mibi gated SPECT [ Time Frame: by ce-MRI and rest Tc99m-mibi gated SPECT ]

Secondary Outcome Measures :
  1. Probability of evolution toward left ventricular remodelling (defined as an increase of end-diastolic volume of>20% between the acute phase and 6-montcontrol) [ Time Frame: of end-diastolic volumeof>20% between the acute phase and 6-montcontrol) ]
