I20.9: Angina pectoris, unspecified
The heart is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart. Your heart is not getting enough oxygen. This can happen when deposits have narrowed the coronary arteries, for example. The circulatory disorder becomes particularly noticeable when one exercises physically. Then there is not enough oxygen in the heart muscle.
One may then be in pain or have other symptoms. One may feel nauseous or short of breath. The chest pains usually extend into the left arm. However, they may also extend into the abdomen or the jaw.
