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.

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.
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.

Please tell me if angina pectoris and myocardial infarction are the same disease?

No.. Angina Pectoris refers to chest pain, specifically spasms of the pectorals muscle, but usually the chest in general. This MAY be a symptom of a heart attack, which is also called, a myocardial infarction (MI). Myocardial means heart muscle and infarction is the lack of blood flow, causing the MI, and then, the angina pectoris. Chest pain may also be caused by other things besides the heart.

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.
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.

How are angina pectoris and myocardial infarction different?

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.

Is the pain that occurs in angina pectoris and myocardial infarction the same?

Chest pain. Typically the pain of angina pectoris resolves with rest and lasts just a few minutes at most. Heart attack pain typically is a resting pain and is like angina but worse. They are both caused by myocardial ischemia but the angina ischemia is reversible. The heart attack ischemia results in death of some of the heart's muscle.
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.

Do patients with untreated stable angina develop unstable angina leading to myocardial infarction?

Depends. Patients with stable angina (sa) have by definition coronary artery disease. This puts them at increased risk of developing an acute myocardial infarction. However, recent studies looking at the use of current medicnes have shown them to be very effective in treating sa. Additionaly, coronary intervention (placing stents, for example) has not been shown to prevent heart attacks in patients with sa.
Depends. On level of medical treatment. But, yes unstable angina and acs can affect any one.

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.

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.
