What is the difference between unstable angina and MI?

People who have unstable angina do not have signs of heart attack on their ECG or blood tests. Non-ST-segment elevation MI is a heart attack that doctors can identify by blood tests but that does not produce typical changes (ST-segment elevation) on an ECG.

What is difference between angina pectoris and myocardial infarction?

The feature effective in differentiating old myocardial infarction was the "area at rest"; those effective in differentiating angina pectoris were a "decrease in area" and a "decrease in movement." These effective features have almost always differentiated old myocardial infarction and angina pectoris.

How do you differentiate between heart attack and myocardial infarction?

A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. "Myo" means muscle, "cardial" refers to the heart, and "infarction" means death of tissue due to lack of blood supply.

What is the difference between acute myocardial infarction and myocardial infarction?

A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to a part of the heart, causing damage to the heart muscle.
...

Does unstable angina show on ECG?

The diagnosis of unstable angina and non-STEMI is predominantly based on the ECG and cardiac enzymes. Physical examination, as previously described, is non-specific. The ECG tracing can have multiple abnormalities, but, by definition, there is no ST segment elevation. The most common finding is ST segment depression.

How serious is unstable angina?

An attack of unstable angina is an emergency and you should seek immediate medical treatment. If left untreated, unstable angina can lead to heart attack, heart failure, or arrhythmias (irregular heart rhythms). These can be life-threatening conditions.

What is the main cause of a myocardial infarction?

The causes of myocardial infarction, or a heart attack, all involve some kind of blockage of one or more of the coronary arteries. The coronary arteries provide the heart with oxygenated blood, and if they become blocked, the heart will become oxygen starved, killing heart tissue and causing a heart attack.

How long does unstable angina pain last?

Unstable angina may not respond to rest or nitroglycerin. It needs urgent attention. Usually lasts 5 minutes; rarely more than 15 minutes.

How can you tell if you have angina?

Angina symptoms include chest pain and discomfort, possibly described as pressure, squeezing, burning or fullness. You may also have pain in your arms, neck, jaw, shoulder or back.
...
Other symptoms that you may have with angina include:

1. Dizziness.
2. Fatigue.
3. Nausea.
4. Shortness of breath.
5. Sweating.

What are the three major characteristics used to diagnose a myocardial infarction?

The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period.

What is the drug of choice for myocardial infarction?

Analgesia and anti-emetics. The pain of myocardial infarction is usually severe and requires potent opiate analgesia. Intravenous diamorphine 2.5–5 mg (repeated as necessary) is the drug of choice and is not only a powerful analgesic but also has a useful anxiolytic effect.

How long can you live with myocardial infarction?

About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.
