Lack of blood flow to heart muscle due to blockage?

• A. Coronary
• B. Costal
• C. Coronary Ischemia
• D. Conjunctivitis

Answer: (C)

The main idea here is reduced blood supply to heart tissue. When the heart muscle isn’t getting enough blood due to a blockage in the coronary arteries, this is called coronary ischemia. Ischemia means a shortage of blood (and thus oxygen) to a tissue, leading to symptoms like chest pain (angina) and, if prolonged, potential heart damage.

That’s why coronary ischemia is the best term for “Lack of blood flow to heart muscle due to blockage.” The word coronary refers to the heart’s arteries, but by itself it doesn’t describe the lack of flow. Costal relates to ribs, and conjunctivitis is an eye condition, so they don’t fit the scenario.
