Demand Ischemia


demand ischemia

Demand ischemia is another type of heart attack for which blockages in the arteries may not be present. It occurs when a patient’s heart has an increased need for oxygen that exceeds the body’s ability to supply it. It may occur in patients with infection, anemia, or tachyarrhythmias (abnormally fast heart rates). Blood tests will show the presence of enzymes that indicate damage to the heart muscle.
