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.

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.

Hello doc. .. could deep vein thrombosis cause myocardial infarction?

No. But it can cause pulmonary embolism or migration of the clots to lungs. Clinically sometimes hard to differentiate, totally different conditions otherwise. Read more...

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...

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...

What are stable and unstable angina and myocardial infarction, and links to other infomration?

Angina. . Stable angina pain is under control with medication. Unstable angina : pain is unstable and increases in intensity or occurs at rest. Myocardial infarction : death of heart muscle. Read more...
Continuum. Angina can be quite severe and respond to rest, oxygen, nitroglycerin. And fully recover with no muscle death. The pain fibers are the same source. Some myocardial infarction can be asymptomatic all the way to the worst, ominous, pain ever! there is heart muscle death as the defining entity may need surgery or intervention. Read more...

I need to know what's an inferior myocardial infarction?

A heart attack. It is a heart attack in the bottom part of the left ventricle. Read more...
Heart attack. Inferior myocardial infarction is a heart attack on the bottom of the heart. This portion of the heart is frequently served by the right coronary artery but occasionally by the circumflex coronary artery. When the artery closes, the bottom of the heart does not get any blood, and the muscle of the heart is injured. Read more...

I was wondering is angina pectoris and myocardial infarction the same disease?

Not. Angina means your heart isn't receiving enough oxygen to meet its needs. However, it's reversible. Mi means that the deficiency in circulation is so severe and prolonged that there has been irreversible heart damage with cell injury and death. Read more...
On same spectrum. Angina is a miss match of the amount of blood needed and delivered to the heart muscle which results in chest pain. This pain is typically of a few mins duration brought on by exercise or stress and relieved by rest. It can occur over the left chest but can also radiate to the jaw and left arm and be quite variable. A mi is death if heart muscle due to complete blockage in a coronary artery. Read more...
