Ventricular ischemia refers to a condition where there is a reduction in the blood supply to the ventricular walls of the heart. This can be caused by a variety of factors, including atherosclerosis, which is the buildup of plaque in the coronary arteries, or by conditions that increase the heart's demand for oxygen, such as anemia or hyperthyroidism. When the heart muscle does not receive enough oxygen-rich blood, it can lead to chest pain, shortness of breath, and other symptoms. If the ischemia is severe and prolonged, it can result in damage to the heart muscle, a condition known as myocardial infarction or heart attack. read more >>

Myocardial ischemia occurs when blood flow to your heart is reduced, preventing it from receiving enough oxygen. ... Myocardial ischemia, also called cardiac ischemia, can damage your heart muscle, reducing its ability to pump efficiently. A sudden, severe blockage of a coronary artery can lead to a heart attack.read more >>
