Practice Question

A myocardial infarction affects which of the following blood vessels of the heart?

Answer Choices:

Correct Answer:

Coronary

Rationale:

💓A myocardial infarction, or heart attack, occurs when the blood supply to part of the heart muscle is blocked.

🩸This blockage happens specifically in the coronary arteries, which supply oxygen-rich blood to the heart tissue.

⚠️When one of these arteries becomes occluded, the heart muscle tissue suffers from a lack of oxygen, resulting in tissue death.

📉Prompt restoration of coronary blood flow is critical to preventing permanent damage or death of the affected heart area.

📌Core Message

Coronary arteries supply the heart with oxygenated blood, and a blockage in these vessels leads to a myocardial infarction.
