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.
Myocardial ischemia occurs when the blood flow through one or more of your coronary arteries is decreased. The low blood flow decreases the amount of oxygen your heart muscle receives.Myocardial ischemia can develop slowly as arteries become blocked over time.Or it can occur quickly when an artery becomes blocked suddenly. Conditions that can cause myocardial ischemia include: 1  Coronary artery disease (atherosclerosis).he low blood flow decreases the amount of oxygen your heart muscle receives.
