Infarction Definition:

A sudden reduction or stoppage of blood flow.

Related Terms: Myocardium

Stedman's defines an infarction as a:

"Sudden insufficiency of arterial or venous blood supply...."

The area of muscle or other tissue damaged by the infarction is known as the infarct

Thus, Schmidt describes an infarction as:

"Infarction: the process which leads to the formation of an infarct: i.e. the formation of a blood clot in a blood vessel, the resulting obstruction to the circulation, the swelling, the death of tissue etc."

A heart attack is often described, in medical terms, as a myocardial infarction, an infarction at the myocardium (the primary heart muscle).
