Study Arms (2)

Treated Group

EXPERIMENTAL

Intracoronary injection in the infarcted-related artery of 100 million bone marrow mononuclear cells resuspended in a 10 ml solution of saline with autologous serum.

Procedure: Autologous Bone Marrow Mononuclear Cells (ABMMC) Transplantation

Control Group

PLACEBO COMPARATOR

Intracoronary injection in the infarcted-related artery of placebo solution consisting of a saline containing autologous blood serum.

Procedure: Autologous Bone Marrow Mononuclear Cells (ABMMC) Transplantation

Interventions

Catheter based stem cells delivery of 100 million cells resuspended in a 10 ml solution of saline with autologous serum. About 100 ml of Bone Marrow aspirate were harvested from iliac crest between the fifth and seventh day after myocardial infarction. ABMMC were isolated by density gradient centrifugation on Ficoll-PaqueTM plus (Amersham Biosciences) and manipulated under aseptic conditions for injection, after being filtered through 100 um nylon mesh to remove cell aggregates.

Eligibility Criteria

Age30 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.
  • Age between 30 and 80 years old.
  • 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.

You may not qualify if:

  • Patients will be ineligible if presenting any of the characteristics described below:
  • AMI related artery presenting TIMI \< 3 at the moment f cell injection.
  • Left Main Coronary Artery Lesion of \>50% or multivessel coronariopathy (\>70% lesion in vessels with \>2,0mm diameter in left anterior descending, circumflex and right coronary territory) indicating the need for CABG or angioplasty with three or more stents implant.
  • Coronary anatomy, after thrombolytic reperfusion, presenting no need for angioplasty with stent implant.
  • Cardiac arrest or Killip IV AMI at admission with need of ventilatory support.
  • Cardiogenic shock persisting up to the third day after AMI (with need of Intra-aortic balloon pump or vasopressors).
  • AMI mechanical complications (ventricular septal defect, papillary muscle rupture, and left ventricular free wall rupture).
  • Significant valve disease, defined as aortic stenosis (mean systolic pressure gradient across the aortic valve \>50mmHg), mitral stenosis with a valvar area less than 1,5 cm,2 moderate to severe aortic and/or mitral regurgitation.
  • Chronic use of immunosuppressive agents.
  • \> 2,0 mg/dl creatinine or previous dialysis treatment.
  • Presence of fever on the past 48h before injection glaring active systemic infection according to ACCP/SCCM (American College of Chest Physicians/Society of Critical Care Medicine) sepsis definition.
  • Sustained ventricular tachycardia 48h after AMI.
  • Illicit drugs abuse or alcohol abuse (based on DSM IV).
  • Any co morbidity, with survival impact in two years.
  • Myocarditis
  • +6 more criteria
