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.
Blood flow with heart failure. In CHF (congestive heart failure), the heart muscle becomes weaker. When the heart muscle is weakened, it is less forceful in pumping blood throughout the body. Less blood moves out of the heart. The body has several ways to try to keep the same amount of blood flow moving. First, the heartâs chambers (the atria and ventricles) stretch to hold more blood.
