What is angina?

Angina, or angina pectoris, is a tightness, squeezing, or pain in the chest that occurs when the heart muscle does not get enough blood and oxygen. Angina is not a medical condition in itself; it is a symptom of heart disease.

There are two types of angina: stable and unstable angina. In stable angina, chest pain is usually brought on by exertion (e.g. exercising or stress). The symptoms usually settle after resting.

In unstable angina, chest pain can develop unexpectedly and may occur when resting or sleeping or following minimal exertion. The pain is usually much more severe and prolonged. Unstable angina is a severe and dangerous form of angina that needs urgent investigation.

In general, the outlook for people with angina is quite good. With treatment, most people can lead a normal or near normal life.
