Difference Between Angina Pectoris And Myocardial Infarction
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.
Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more
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.See 1 more doctor answer
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.
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!

Do patients with untreated stable angina develop unstable angina leading to myocardial infarction?
Do patients with untreated stable angina end up developing unstable angina leading to myocardial infarction?
Very likely: The key is untreated. Medical treatment is effective. See your doctor and get treated.
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.
Continuum: Both are a result of inadequate blood supply to the heart muscle. Acute coronary syndrome means that the imbalance is sufficient to cause symptoms that prompt aggressive intervention, but may not result in permanent heart damage; a myocardial infarction implies that overt heart damage has occurred, hence positive markers of tissue damage.
Not sure of your?: CHF may be independent of mi but mi is most common cause of CHF (systolic).
Yes: Myocardial infarction ("heart attack") is permanent injury to heart muscle from lack of blood supply. Heart failure is a syndrome that can occur from many causes when the heart doesn't pump effectively. One of those causes can be myocardial infarction but CHF can also occur from high blood pressure, valve abnormalities, rhythm disturbances, infection, tumor, senescence and many, many other causes.See 1 more doctor answer
Arrhythmia: The most common early complication of myocardial infarction is arrhythmia typically ventricular fibrillation. If this occurs in the hospital, it responds promptly to cardioversion. If it occurs outside the hospital it can result in sudden death. The highest period of risk occurs in the first 48 hours.See 1 more doctor answer
Angina is chest pain that is caused by poor blood flow to the heart muscle. Angina is not an actual disease, but rather a symptom of an existing heart problem. Most commonly, this underlying problem is due to an obstruction of the coronary blood vessels that surround the heart. There are different types of angina including stable angina, unstable ...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
