Brief Summary:
Most studies on intracoronary bone marrow mononuclear cell (BMC) transplantation for acute myocardial infarction (AMI) involve treatment 3-7 days after primary percutaneous coronary intervention (PCI); however, the optimal timing is unknown. The present study assessed the therapeutic effect at different times after ST-elevation myocardial infarction (STEMI).
Detailed Description:
On the basis of experimental studies that bone marrow mononuclear cells (BMCs) transfer in the injured tissue can promote regional myocardial perfusion and improved cardiac function, several clinical trials have shown that intracoronary bone marrow mononuclear cell (BMC) transplantation in acute myocardial infarction (AMI) patients several days after myocardial reperfusion is safe and may enhance the improvement of left ventricular ejection fraction (LVEF). The timing of BMC administration, baseline LVEF, dosage of BMC and other factors has been linked to improvement in LVEF after BMC transplantation. In our previous work, we gave BMCs within 24 hours after emergency percutaneous coronary intervention (PCI) and found that it was safe and effective . In addition, there are another report about longer time from symptom onset to BMC infusion (2-4 weeks), which also appeared effective . The timing of intracoronary stem cell administration may have a critical effect on cell engraftment and may be responsible for the various biological and functional responses to therapy. However, few studies have directly addressed the optimal timing of cell injections. Therefore, in this prospective randomized study, BMCs were given at different times (within 24 hours, 3 to 7 days, or 7 to 30 days after reperfusion) to investigate whether the timing of therapy affects the therapeutic response of AMI patients.
