Angina was first described in 1772 by the English physician William Heberden in twenty patients who suffered from "a painful and most disagreeable sensation in the breast, which seems as if it would extinguish life, if it were to increase or to continue." Such patients, he wrote, "are seized while they are walking (more especially if it be uphill, and soon after eating); but the moment they stand still, all this uneasiness vanishes."
The word angina comes from the Latin verb angere meaning "to choke or throttle". Angina is now considered to be the same as angina pectoris, a reference to the Latin pectus, "chest". Latin angina "infection of the throat", from Greek ankhone "a strangling".
