ICD-Code I20.9: Angina pectoris, unspecified
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.
When coronary arteries have narrowed as a result of deposits, for example, then in certain situations the heart is not supplied with enough oxygen. This can happen when you exert yourself physically. In some forms of the disease, however, the heart is not supplied with enough oxygen even at rest. If the oxygen in the heart muscle is not sufficient, then the person may experience pain in the chest area or other symptoms. For example, they may feel sick or have difficulty breathing. It is also possible that the pain radiates to other parts of the body such as the left arm, abdomen or jaw.
