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

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

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

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. ...Read more

How are angina pectoris and myocardial infarction different?

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. ...Read more

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. ...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

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

Heart Attack (Definition)

Heart attack is a life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more
