Ischemia is

• A. An inadequate blood supply to an organ or part of the body, especially the heart muscles.
• B. An excess blood supply to tissues
• C. Inflammation of the arteries
• D. A viral infection of the heart

Answer: (A)

Ischemia means an inadequate blood supply to an organ or part of the body, which deprives tissues of oxygen and nutrients needed to function. In the heart, reduced blood flow from narrowed or blocked coronary arteries can cause chest pain (angina) and, if not resolved, may lead to tissue damage or heart attack. The other statements don’t fit because an excessive blood supply is called hyperemia, inflammation of the arteries is arteritis, and a viral infection of the heart describes myocarditis.
