Damage to the heart muscle caused by a thrombus blocking a coronary artery is called?

• A. Cholecystectomy
• B. Gastritis
• C. Coronary Thrombosis
• D. Colitis

Answer: (C)

This question focuses on the specific term for a clot forming in the heart’s blood vessels and causing damage to the heart muscle. When a thrombus blocks a coronary artery, the heart muscle beyond that blockage is deprived of oxygen and can become injured or die—that injury is a myocardial infarction, but the event itself is described by coronary thrombosis. Among the options, coronary thrombosis best names the process that leads to the heart damage, since the other choices refer to other organs (gallbladder, stomach, colon) or to inflammation rather than to a clot in the heart. So the correct term is coronary thrombosis.
