What does ischemic mean?
Ischemic is a medical adjective describing a condition in which blood flow to an organ or tissue is reduced or obstructed. The resulting shortage of oxygen can injure cells and may lead to serious complications. Common examples include ischemic stroke, ischemic heart disease, and ischemic bowel or brain injury. The word is especially associated with strokes, although ischemia can affect many parts of the body. In general conversation, "ischemic" is usually encountered through medical diagnoses and reports rather than used independently. It should not be confused with ischemic stroke itself: ischemic is the adjective describing the condition or damage, while stroke names a particular clinical event. The term comes from the Greek roots for "to restrain" and "blood," reflecting the original sense of blood being held back from a part of the body.

Where does ischemic come from?
Ischemic derives from the Greek iskhein, meaning "to restrain," and haima, meaning "blood." The related noun ischemia was formed in the nineteenth century from the same elements and originally referred to the local retention of blood rather than the modern condition of inadequate blood flow. The English adjective developed through the scientific vocabulary of medicine, with the spelling "ischemic" becoming standard in American usage and "ischaemic" being widely used in British usage.
