RESUMO
Acute myocardial infarction with cardiogenic shock (AMI-CS) refers to the rapid decrease in cardiac output in a short period of time, and it leads to severe insufficient perfusion of various organs and causes systemic microcirculatory dysfunction, which is the most common cause of the death of patients with acute myocardial infarction (AMI). At present, the main strategy for clinical treatment of AMI-CS is revascularization, which reduces the mortality of AMI-CS. However, myocardial ischemia and reperfusion can cause ischemia/reperfusion (I/R) injury, induce myocardial mitochondrial dysfunction, and a large amount of reactive oxygen species (ROS) accumulation. Mitochondrial-mediated apoptosis of cardiomyocytes is the main reason of cardiomyocyte death during reperfusion injury. This article summarizes the role of mitochondrial in AMI-CS, which focus on three aspects of mitochondrial permeability transition pore (mPTP) opening, mitochondrial autophagy and mitochondrial fusion/division. It is expected to provide new ideas for clinical AMI-CS and identify potential complications targets.
