Abstract:

BACKGROUND: The stem cells transplanted into the damaged heart tissues can differentiate into cardiomyocytes, which bring new hope for the research of ischemic heart disease.
OBJECTIVE: To explore the feasibility and safety of stem cell transplantation for the treatment of ischemic heart disease.
METHODS: Various experimental methods to the feasibility and safety of stem cell transplantation for the treatment of ischemic heart disease were analyzed. REPAIR-AMI experiment was a randomized and double-blind and placebo-controlled multi-center study that used to analyze the therapeutic effect of intracoronary transplantation of bone marrow progenitor cells immediately after acute myocardial infarction. MAGIC Cell-3-DES experiment was used to evaluate the safety of granulocyte colony-stimulating factor mobilized stem cell therapy and the effect of intracoronary injection of mobilized peripheral blood stem cells on the treatment of acute myocardial infarction and old myocardial infarction. BOOST experiment was the randomized controlled study on autologous bone marrow cell transplantation through coronary vein after myocardial infarction. PROTECT-CAD experiment was the randomized controlled clinical trial about the direct injection of stem cells into the myocardial for the treatment of ischemic heart disease.
RESUTLS AND CONCLUSION: Stem cell transplantation may improve the left ventricular systolic function and left ventricular diastolic function as well as the coronary flow reserve, and the related studies have been confirmed. Stem cell transplantation for the treatment of ischemic heart disease can increase the left ventricular jection fraction. As the less clinical accident, stem cell therapy cannot increase the risk of restenosis based on the treatment of drug-eluting stents. It is safe and feasible of stem cell transplantation for the treatment of ischemic heart disease. Large sample, long scale and multi-center randomized controlled studies are needed to further evaluate the effect and risk of stem cell transplantation.
