What are the differences between myocardial infarction and myocardial ischemia?

What are the differences between myocardial infarction and myocardial ischemia?

Ischemia: Ischemia is a term for tissue not getting enough oxygen(almost the same as not enough blood supply). Infarction is the end result of too much ischemia, it means death of the tissue. In other words infarction is the result of severe prolonged ischemia. ...Read more

Ischemia (Definition)

Ischemia is a symptom in which a person does not have enough blood supply to a part of the body, making that part of the body "ischemic". For example, in a heart attack, a coronary artery is blocked so blood cannot get to the heart muscle beyond the blockage point. The heart muscle lacking ...Read more

Small myocardial infarction with Small -medium pharmacologically induced myocardial ischemia in that distribution. What are the the implications?

Small myocardial infarction with  Small -medium pharmacologically induced  myocardial ischemia in that distribution. What are the the implications?

Reversible defect?: If you're describing what we term a "reversible defect", wherein the heart seems OK at rest and not OK when stimulated (by exercise or medication), then this would mean that area of the heart is still vulnerable to damage (heart attack). This needs to be addressed and treated. You may need cardiac catheterization to define the anatomy of the vessel supplying that area with blood. ...Read more

Does ischemia or thrombosis cause myocardial infarction?

Does ischemia or thrombosis cause  myocardial infarction?

Ischemia vs MI: Cholesterol plaque develops in the heart arteries. Progressive narrowing - usually greater than 70% - can lead to lack of blood flow to the heart muscle during exercise or rest and causes angina or ischemia. Myocardial infarction is due to the rupture of a plaque which causes a blood clot to form (thrombosis) in the artery blocking blood flow to that area of the heart muscle which then dies. ...Read more

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

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... ...Read more

Can any doc tell me what's the difference between myocardial infarction and myocardial ischemia?

Can any doc tell me what's the difference between myocardial infarction and myocardial ischemia?

Damage done: Myocardia ischemia means heart muscle not getting enough oxygen. Frequently this is angina. When the lack of oxygen is prolonged there is destruction of the muscle: this is a heart attack or myocardial infarction. ...Read more

What is the difference between a myocardial infarct, ischemia and angina?

What is the difference between a myocardial infarct, ischemia and angina?

Maybe very serious: Ischemia means an area of the heart is not getting enough blood usually because of a blockage in an artery. The severity depends on whether it is a major artery or not. An intact occurs when the artery is completely blocked and the muscle dies. Angina is the pain felt when ischemia occurs. ...Read more

Are myocardial infarctions curable?

Are myocardial infarctions curable?

No: A myocardial infarction is an acute event in which a portion of the heart is irreversably destroyed, usually by a blocked artery. The major lesson is that this damage is potentially avoided if people come to an er promptly when they have symptoms, which have been discussed elsewhere. We have a short time window to use modern treatment to save the heart and prevent complications and death. ...Read more

Infarction (Definition)

When the blood supply of a tissue is compromised by whatever mechanism, the tissue will stop working and if blood flow is not restored, the tissue will eventually die ("infarct", both verb and noun). The clinical picture that runs with development of an infarct ("heart attack"; ...Read more
