Difference Between Angina and Myocardial Infarction

Many people are not aware of Angina and Myocardial. Those who know them become confused in their use. The words are concerned with the situation when one experiences a pain in his chest.  These words are concerned with the heart disease. People should be aware of the difference between the meanings of the words which are used for different problems relating to heart.


Angina pectoris refers to choking pain when a person feels uncomfortable sensation or pain in his chest. This pain is felt when a portion of the heart does not receive sufficient oxygen. The blockage of oxygen may be due to blocked arteries. This causes lack of blood and hearts muscles become deficient in oxygen. This condition may be due to many reasons such as smoking, heredity, and emotional stress. One who has experienced Angina knows how terrible it is. Angina takes place for a few minutes as the supply to the heart becomes regular soon. There are two types of Angina- stable Angina and unstable angina. Unstable Angina may lead to Myocardial Infarction.

Myocardial Infarction

When the supply of blood to the heart is blocked due to the blood vessels, it is called Myocardial Infarction. Heart muscles get damaged, when the heart does not bet enough oxygen. This damage may be permanent. It is also called heart attack which occurs due to blockage of coronary artery. This may takes place when plaque surrounding arteries gets ruptured due to collection of fatty acids on the walls of arteries. Due to the lack of blood supply and oxygen tissues of heart die. This death of muscle of tissues is called infarction in medical language.

The symptoms of myocardial infarction include nausea, pain in chest, anxiety, panting, palpitation etc.  A person needs quick medical help when he suffers MI. The damage to the heart can be seen through Echocardiography and Electro Cardiogram. Aspirin and oxygen supply are necessary in emergency.

Angina is temporary. The heart starts functions normally when the blood supply to it becomes normal. But in MI the heart gets damaged and needs immediate medical help. In MI there is a permanent damage while it is not so in Angina.
