Ischemic refers to a condition where there is a reduced blood flow to a specific area of the body. This lack of blood supply can lead to a shortage of oxygen and nutrients, which are essential for the cells to function properly. Ischemia can occur in various organs, including the heart, brain, and limbs. One common example of ischemia is ischemic heart disease, where the heart muscle does not receive enough blood, potentially leading to chest pain or a heart attack. Another example is ischemic stroke, which happens when blood flow to the brain is blocked, resulting in brain cell damage.
