Which condition occurs when a coronary artery is blocked, leading to heart muscle death?

Explanation:
Blockage of a coronary artery stops blood flow to a part of the heart muscle. Without blood, that heart tissue is deprived of oxygen and dies, a process called infarction. When this happens, the condition is called a myocardial infarction, commonly known as a heart attack. Prompt treatment to restore blood flow limits the damage. The other options involve areas outside the heart—dementia affects the brain, gastric ulcers affect the stomach lining, and hepatitis affects the liver—so they don’t describe a heart attack caused by a blocked coronary artery.
