In medicine, ischemia, also spelled as ischaemia or ischæmia, (/ɪˈskiːmɪə/; from Greek language ισχαιμία, ischaimía; isch- root denoting a restriction or thinning or to make or grow thin/lean, haema blood) is a restriction in blood supply to tissues, causing a shortage of oxygen and glucose needed for cellular metabolism (to keep tissue alive). Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue. It also means local anemia in a given part of a body sometimes resulting from congestion (such as vasoconstriction, thrombosis or embolism).

Ischemic means having or showing symptoms of ischemia, while nonischemic means "not related to or showing signs of ischemia".
