ABSTRACT
In cardiac surgery such as myocardial infarction, congenital heart disease, and heart transplantation, myocardial ischemia-reperfusion (I/R) damages mitochondria, which in turn causes myocardium energy metabolism disturbance, homeostatic destruction, reactive oxygen species production and DNA damage, and activates myocardium apoptosis and necrosis signals, which eventually lead to myocardial dysfunction or heart failure. Different from the previous I/R treatment targets focusing on a certain pathway or a certain medium, autologous mitochondrial transplantation (AMT) is an emerging method, which transplant viable and respiration-competent mitochondria from healthy organs or tissues to the injured sites which suffer from I/R injury, to replace or repair damaged mitochondria. In recent years, AMT has achieved remarkable results in the prevention and treatment of myocardial I/R. This article reviews the role and mechanism of AMT in I/R myocardial protection.
