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.
Angina is caused by reduced blood flow to your heart muscle. Your blood carries oxygen, which your heart muscle needs to survive. When your heart muscle isn't getting enough oxygen, it causes a condition called ischemia. The most common cause of reduced blood flow to your heart muscle is coronary artery disease (CAD).Your heart (coronary) arteries can become narrowed by deposits called plaques. This is called atherosclerosis.This reduced blood flow is a supply problem â your heart is not getting enough oxygen-rich blood.he most common cause of reduced blood flow to your heart muscle is coronary artery disease (CAD).
