Title: Cell Therapy for Coronary Heart Disease: Infusion of Autologous Ex Vivo Cultivated Endothelial Progenitor Cells (EPCs)" and Autologous Bone Marrow Progenitor Cells in Crossover Design for Improvement of Vascularization and Cardiac Function
Brief Summary: Impaired contractile function after a heart attack and due to coronary heart disease is a major cause of "heart failure" limiting quality of life and prognosis, which cannot be prevented even with optimal standard therapy.

The aim of the current trial is to investigate whether infusion of progenitor cells into the coronary artery supplying the most dyskinetic left ventricular area may improve left ventricular contractile function, compared to no cell infusion in the control group, in patients with old (\>= 3 months) myocardial infarction.


Options:
A: Inclusion Criteria:

* Patients will be eligible if presenting all characteristics described below:

  * ST segment elevation myocardial infarction in two or more contiguous leads, and according to the WHO definition, at least one of the following two:

    i) Presence of chest pain. ii) Elevation of the myonecrosis markers.

  * Ejection fraction ≤50% on Echocardiogram (Simpson) and segmentary dysfunction of the infarction area, measured between the 3rd and 5th day post AMI.

Among patients submitted to thrombolytic therapy, the angioplasty of the related artery should be preferably done up to 24h after thrombolysis, with a maximum deadline of 72h after thrombolysis.

Exclusion Criteria:

* Patients will be ineligible if presenting any of the characteristics described below:

  * AMI related artery presenting TIMI \< 3 at the moment f cell injection.
