Ischemia, or insufficient blood circulation, as occurs during a heart attack or stroke, causes tissues to be starved of oxygen. In the highly oxygenated tissues of the mind and heart, ischemia can cause irreversible harm in less than three to four minutes at normal body temperature. Reperfusion injury may be the injury caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen.
