Brain ischemia. Brain ischemia (a.k.a. cerebral ischemia, cerebrovascular ischemia) is a condition in which there is insufficient blood flow to the brain to meet metabolic demand. This leads to poor oxygen supply or cerebral hypoxia and thus to the death of brain tissue or cerebral infarction / ischemic stroke.
When blood can't get to your heart, your heart muscle doesn't get the oxygen it needs. Without oxygen, its cells can be damaged or die. The key to recovery is to get your blood flow restored quickly. Get medical help right away if you think you're having symptoms of a heart attack.
