Purpose

This study will assess the safety and efficacy of intracoronary artery administered autologous bone marrow derived stem cells in subjects post ST segment elevation myocardial infarction (STEMI). This will be assessed by evaluating and comparing the autologous stem cell treatment group to the control group in terms of the occurrence of AE's, SAE's and Major Adverse Cardiac Events (MACE), by the change in myocardial perfusion (RTSS) measured quantitatively by gated single photon emission computed tomography myocardial perfusion imaging (gated SPECT MPI), and other secondary endpoints such as LVEF measured by cardiac MRI in addition to other endpoints.
