Which term is the medical event caused by blocked coronary arteries depriving heart muscle of oxygen?

• A. Myocardial Infarction
• B. Hypoglycemia
• C. Epilepsy
• D. Hypersensitivity

Answer: (A)

When a coronary artery becomes blocked, the heart muscle it feeds is deprived of oxygen. That lack of oxygen causes injury and cell death in the heart tissue, which is known as a myocardial infarction, commonly called a heart attack. This event is specifically about the heart muscle being starved of oxygen due to blocked blood flow, not about sugar levels, brain seizures, or immune reactions. Hypoglycemia is low blood sugar, epilepsy involves brain electrical activity, and hypersensitivity is an exaggerated immune response.
