ICD-Code I20.1: Angina pectoris with documented spasm
You are having attacks of chest pain.
The heart muscle is supplied with oxygen-rich blood via the coronary arteries. The coronary arteries are blood vessels that run around the outside of the heart. The coronary arteries can get narrow due to deposits of fat and calcium. Various things favor these deposits. These include smoking, high blood pressure, and other disorders. The porosity of the coronary arteries can also be restricted for other reasons. For example, if the blood vessel wall is damaged or the muscles in the blood vessel wall cramp up.
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. As a result, you may have pain in the chest area or 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.
