Abstract: Acute myocardial infarction is an event of myocardial necrosis caused by unstable ischemic
syndrome. Myocardial infarction (MI) occurs when blood stops flowing to the cardiac tissue
or myocardium and the heart muscle gets damaged due to poor perfusion and reduced oxygen
supply. Mitochondria can serve as the arbiter of cell fate in response to stress. Oxidative metabolism
is the function of mitochondria within the cell. Cardiac cells being highly oxidative tissue
generates about 90% of their energy through oxidative metabolism. In this review, we focused on
the role of mitochondria in energy generation in myocytes as well as its consequences on heart
cells causing cell damage. The role of mitochondrial dysfunction due to oxidative stress, production
of reactive oxygen species, and anaerobic production of lactate as a failure of oxidative metabolism
are also discussed.
