Safety and Efficacy of Intracoronary Adult Human Mesenchymal Stem Cells After Acute Myocardial Infarction
- Conditions
- Acute Myocardial Infarction

- Drug: Control group
- Registration Number
- NCT01392105
- Lead Sponsor
- Yonsei University
- Brief Summary
Early reperfusion strategies in tandem with remarkable advances in drugs and devices for treating myocardial infarction (MI) have contributed to a reduction in early mortality, but cardiovascular disease remains the leading cause of death worldwide. Current management strategies cannot solve the problem of cardiomyocyte loss and consequent progression of heart failure. In this respect, stem-cell therapy has shown potential benefits for repairing the damaged myocardium. Mesenchymal stem cells (MSCs) have been considered to be attractive therapeutic candidates because of their high capacity for replication: paracrine effect: ability to preserve potency: and because they do not cause adverse reactions to allogeneic versus autologous transplants. Intracoronary injection of stem cells seems to be safe, but only one clinical trial using MSCs via the intracoronary route in the setting of acute myocardial infarction (AMI) has been carried out. The investigators therefore assessed the safety and efficacy of intracoronary autologous bone marrow (BM)-derived human MSCs in patients with AMI.

Group Intervention Description Mesenchymal stem cell treatment group Mesenchymal stem cell - Control group Control group All patients were required to have successful revascularization of an infarct-related artery on coronary angiography at the time of randomization. All patients received aspirin (300 mg loading dose, then 100 mg daily) and clopidogrel (600 mg loading dose, then 75 mg daily) with optimal medical therapy according to the American College of Cardiology (ACC)/ American Heart Association (AHA) guidelines for treatment of ST-segment elevation myocardial infarction (STEMI)
- Primary Outcome Measures
Name Time Method Absolute changes in global LVEF by SPECT baseline and 6 months Absolute changes in global left ventricular ejection fraction (LVEF) as measured by SPECT 6 months after cell infusion
- Secondary Outcome Measures
Name Time Method Changes in left ventricular end-diastolic volume (LVEDV) baseline and 6 months Changes in left ventricular end-systolic volume (LVESV) baseline and 6 months Changes in regional wall motion score index (WMSI) by Echocardiography baseline and 6 months Major adverse cardiac event (MACE) 6 months MACE was defined as the composites of any cause of death, myocardial infarction, revascularization of the target vessel, re-hospitalization for heart failure, and life-threatening arrhythmia.
