What best describes a condition when a coronary artery becomes blocked and tissue death occurs in heart tissue?

Explanation:
Blockage of a coronary artery stops blood flow to part of the heart, and without oxygen the affected heart muscle begins to die. This death of heart tissue is what defines a myocardial infarction, commonly called a heart attack. Angina is chest pain from temporary ischemia but usually without irreversible tissue death. An aneurysm is a bulging, weakened area of a vessel or heart wall, not an acute death of tissue from a blocked artery. Ventricular failure describes the heart’s pumping weakness, which can occur after an infarction, but it isn’t the tissue-death event itself.
