How is ischemia linked to myocardial infarction, along with thrombosis?

MI: Ischemia is a state of insufficient blood supply to an organ, in this case the heart. When the condition persists it causes death of the tissue/organ - myocardial infarction. The cause of limited supply can be a narrowing of the supplying blood vessel, a blood cloth(thrombosis), a combination of both, or an increased tissue energy need such as in fever/sepsis etc...

MI: All this terminology indicate sequence of events and of pathological significance. Ischemia means partial lack of blood supply. Thrombosis is due to plaque deposition within an artery. Infarction is a total lack of blood supply resulting in death of a muscle or tissue.
