Definition of Angina pectoris

Angina pectoris: Chest pain that is typically severe and crushing with a feeling just behind the breastbone (the sternum) of pressure and suffocation, due to an inadequate supply of oxygen to the heart muscle. The term "angina pectoris" comes from the Latin "angere" meaning "to choke or throttle" + "pectus" meaning "chest". Angina pectoris was first described by the English physician William Heberden (1710-1801) and may be referred to simply as angina.
