Ischemia is a restriction of the blood supply to tissue resulting in a shortage of oxygen.[3] Types include ischemic heart disease, stroke, peripheral vascular disease, and mesenteric ischemia.[4] Symptoms depend on the area of the body affected.[4] Onset may be gradual or sudden.[3]
Gradual cases may occur due to atherosclerosis, fibromuscular dysplasia, vasculitis, or external pressure from a tumor.[3] Sudden cases may occur due to a blot clot, vasospasm, or aortic dissection.[3][5]
Efforts to prevent the condition include a healthy lifestyle.[4] The first documented use of the term is from 1855.[2] The term is from the Greek ischein meaning "to restrain" plus haima meaning "blood".[2]
