What occurs when a coronary artery is completely blocked?

Question

Quizplus · Accepted Answer

When a coronary artery is completely blocked, it prevents blood flow and oxygen to a part of the heart muscle. If this goes on for too long, the affected heart muscle can begin to die. This is known as a heart attack. Angina is chest pain or discomfort that occurs when the heart muscle doesn't get enough blood flow, but it is not the same as a heart attack. Arrhythmia refers to an abnormal heart rhythm, and an obstructive embolism occurs when an object (such as a blood clot) gets stuck in a blood vessel and blocks blood flow. However, neither of these options describe the outcome of a completely blocked coronary artery.
