Abstract: BACKGROUND: Ischemic heart disease is one type of disease that seriously threatens human life and health. Mesenchymal stem cells derived exosomes have shown obvious therapeutic effects and application prospects in ischemic heart disease, and make important research progress.  
OBJECTIVE: To review the therapeutic effect of mesenchymal stem cells derived exosomes for ischemic heart disease, repair mechanisms, optimized plan and improved transplantation strategy.
METHODS: The relevant articles published from January 1973 to March 2022 were searched in PubMed by the first author in February 2021. The English key words were “mesenchymal stem cell, exosome, ischemic heart disease”. Finally, 88 articles were included and analyzed.  
RESULTS AND CONCLUSION: (1) Exosomes secreted by stem cells are one of the most important components of stem cell excretion to play functional regulation which have shown obvious therapeutic effects and application prospects in ischemic heart disease. (2) Mesenchymal stem cells derived exosomes can promote the angiogenesis and protect ischemia-injured myocardial tissue, inhibit cardiac fibrosis and improve immune regulation, finally promote myocardial repair and the improvement of cardiac function. (3) The production or functional properties of mesenchymal stem cells derived exosomes can be optimized by genetic engineering modification, miRNA modification, pretreated of drugs or physical intervention, and improve exosome production, so as to improve their therapeutic effect on ischemic heart disease. (4) Using biomaterials to carry exosomes, two-step delivery method, exosome spray technology or cell membrane modified exosomes and other exosome transplantation optimization strategies can effectively improve the retention rate of mesenchymal stem cell-derived exosomes in injured myocardial tissue, thereby enhancing their therapeutic effect on ischemic heart disease.

Key words: ischemic heart disease, mesenchymal stem cell, exosome, angiogenesis, fibrosis, repair mechanism, optimized plan, transplantation strategy
