Angina

Angina, also known as angina pectoris, is chest pain or pressure, usually due to insufficient blood flow to the heart muscle. Angina is usually due to obstruction or spasm of the arteries that supply blood to the heart muscle. Other causes include anemia, abnormal heart rhythms, and heart failure. The main mechanism of coronary artery obstruction is atherosclerosis as part of coronary artery disease. The term derives from the Latin angere ("to strangle") and pectus ("chest"), and can therefore be translated as "a strangling feeling in the chest".
