Glossary of Terms
Lack of oxygenated blood supply to an organ. In heart disease, ischemia is often used to describe the heart muscle that is not getting the proper amount of oxygen-rich blood because of narrowed or blocked coronary arteries. The symptoms of ischemia depend on the organ that is "ischemic". With the heart, ischemia often results in angina or "chest pain" that can be an early warning of an impending heart attack. In the brain, ischemia can result in a stroke.
