means chest pain or pressure caused by reduced blood flow to the heart muscle, usually from narrowed arteries, not a heart attack itself but its warning shot.
from from latin angina, throat spasm or quinsy, itself from greek ankhone meaning strangling; the word migrated from throats to chests once physicians realized the crushing sensation was cardiac, not tonsillar.
