Angina is the symptom of chest pain that is caused
when an area of heart muscle does not receive enough oxygen rich blood supply
due to a narrowing in one of the coronary arteries. It is characterised by a
tight squeezing sensation across the chest during physical exertion (walking,
climbing stairs etc), that can often feel like a tight band across the chest,
but can also spread or appear in the back, left arm, and the jaw.
