I20.1: Angina pectoris with documented spasm
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. There are muscles in the walls of the coronary arteries. The muscles can change the width of the coronary arteries. In your case, the muscles in the walls of your coronary arteries have gone into spasm. As a result, the coronary artery has got narrower and not enough blood is getting through.
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.
