Outcome measures
Primary outcome
The change of regional myocardial function based on a MRI-segmental analysis at 4 months relative to baseline.
Secondary outcome
Functional:
change of LV ejection fraction at 4 months relative to baseline, measured by MRI and echocardiography, and change in global and regional WMSI measured by echocardiography at 4 months and 12 months relative to baseline;
Infarct related:
change of infarct size at 4 months relative to baseline, measured by MRI;
Clinical:
occurrence within 4 and 12 months of a major adverse cardiac events;
Angiograpic:
the presence of in-stent restenosis and late luminal loss;
Change:
of intracoronary hemodynamic parameters at 4 months relative to baseline.
Background summary
N/A
Study objective
The primary objective of this study is to determine whether intracoronary infusion of autologous mononuclear bone marrow cells or peripheral mononuclear blood cells provides improved recovery of regional left ventricular function after an acute, large myocardial infarction treated by PCI compared to standard therapy.
Study design
N/A
Intervention
After written informed consent has been obtained, MRI measurements and echocardiography are performed minimally 48 hours after PCI. Patients are randomized to a treatment with
1. Intracoronary infusion of autologous mononuclear bone marrow cells;
2. Intracoronary infusion of peripheral mononuclear blood cells; or
3. Standard therapy.
If applicable, bone marrow is aspirated from the iliac crest under local anesthesia or venous blood is collected. Mononuclear cells are isolated from the aspirate or blood by density gradient centrifugation. Within 7 days after PCI and within 24 hours after bone marrow aspiration or venous blood collection, a catheterization for the intracoronary infusion of the autologous mononuclear cells in the infarct related coronary artery is performed. In all patients the follow up is at 1, 4 and 12 months.
The MRI measurements and catheterization are repeated at 4 months.
