Coagulative necrosis is a type of accidental cell death typically caused by ischemia or infarction. In coagulative necrosis, the architectures of dead tissue are preserved for at least a couple of days. [ 1 ]
Necrosis can also result from chemical trauma, with alkaline and acidic compounds causing liquefactive and coagulative necrosis, respectively, in affected tissues. The severity of such cases varies significantly based on multiple factors, including the compound concentration, type of tissue affected, and the extent of chemical exposure.
The only possible sign the first 4 hours is waviness of fibres at border. Later, however, a coagulation necrosis is initiated, with edema and hemorrhage. After 12 hours, there can be seen karyopyknosis and hypereosinophilia of myocytes with contraction band necrosis in margins, as well as beginning of neutrophil infiltration. At 1 – 3 days ...
Necrosis begins after 20 minutes of an infarction. Under 4 hours of ischemia, there are no gross or microscopic changes noted. [2] From 4-24 hours coagulative necrosis begins to be seen, which is characterized by the removal of dead cardiomyocytes through heterolysis and the nucleus through karyorrhexis, karyolysis, and pyknosis.

Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors.
Gangrenous necrosis: ... Dry gangrene is a form of coagulative necrosis that develops in ischemic tissue, where the blood supply is inadequate to keep tissue viable.

Periventricular leukomalacia (PVL) is a form of white-matter brain injury, characterized by the necrosis (more often coagulation) of white matter near the lateral ventricles. [ 1 ] [ 2 ] It can affect newborns and (less commonly) fetuses; premature infants are at the greatest risk of neonatal encephalopathy which may lead to this condition.
