Myocardial Infarction Ischemia
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?
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
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
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 moreSee 1 more doctor answer
Can you briefly describe what is ischaemia? And is myocardial infarction the same with heart attack?
Heart stroke: A heart stroke is also known as a myocardial infarction or heart attack. A blood clot forms in a heart blood vessel. This cuts off flow to a part of the heart and that part dies. This can cause pain, rhythm and pumping disturbances. These things can result in disability or death. ...Read more
Heart attack: Myocardial infarction mean death ("infarction") of heart muscle (card ~heart and myo~muscle). This happens when the heart muscle is not getting the oxygen it needs over a relatively long period of time. This can happen from a narrowing of a blood vessel which reduces flow or from a suddenly, totally blocked vessel. The heart can't stop working, so that part keeps trying to pump blood until the the ...Read more
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
