Angina: Angina
is chest pain or discomfort that occurs if an area of your heart muscle does not get enough oxygen. Angina may feel like pressure or squeezing in your chest. The pain can also occur in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion.
Angina is not a disease. It is a symptom of an underlying heart problem. Angina usually is a symptom of Coronary Heart Disease which is the most common type of heart disease in adults. It occurs if a waxy substance called plaque builds up on the inner walls of the coronary arteries. These arteries carry oxygen-rich blood to the heart.
Therefore plaque buildup narrows and stiffens the coronary arteries. This reduces the flow of oxygen-rich blood to the heart muscle, causing chest pain. Plaque buildup also makes it more likely that blood clots will form in the arteries. Blood clots can partially or completely block blood flow causing a heart attack.

Medical Emergency: If you experience chest pain and you haven't previously been diagnosed with a heart problem call an ambulance.
If you have an angina attack and you've previously been diagnosed with the condition, take the medication prescribed for you. A second dose can be taken after five minutes if the first dose is ineffective. If there is no improvement five minutes after the second dose, call an ambulance.
