Angina manifests as chest pain that result from reduced blood supplying oxygen to the heart (ischemia).
The typical angina pain is in the chest behind the chest bone (sternum) but it can often radiate to the left arm, shoulder or jaw. If you have angina you will have noticed that the pain is related to exertion and is relieved by rest.
An angina attack is also associated with shortness of breath and sweating. If you are a woman you may experience angina slightly differently. Women appear to have more pain in their shoulder and middle back area, and more throat, neck, and jaw pain than men.
If your angina symptoms rapidly worsen and occur at rest this is called unstable angina that may progress to an impending heart attack (myocardial infarction) and you should go to the nearest hospital A&E immediately.
