Myocardial infarction belongs to coagulation necrosis?

Myocardial infarction is not coagulative necrosis.

Myocardial infarction is a disease caused by ischemia and hypoxia of myocardial cells due to coronary artery stenosis and occlusion. In this case, myocardial cells gradually die, but this necrosis is caused by ischemia and hypoxia, not coagulation. Coagulative necrosis is a tissue necrosis caused by blood coagulation disorders. It is characterized by slow blood coagulation and easy thrombosis, resulting in tissue necrosis.

The necrosis mechanism of myocardial infarction and coagulative necrosis are two different concepts. Although both involve tissue necrosis, their pathophysiological processes are different.
