Answers:

1. A. True. The heart muscle receives its blood supply from coronary arteries, which run along the outside of the heart.

2. B. 2. The left main coronary artery (LMCA) and the right coronary artery (RCA) are the two main arteries. They both divide into smaller branches to reach all areas of the heart.

3. B. False. When a weak heart cannot pump blood as well as it should, that is known as heart failure. CAD is the result of reduced flow of oxygen and nutrients to the heart.

4. E. All of the above. However, some people with CAD have no symptoms or may have only mild symptoms.

5. A. True. The buildup of plaque in the inner lining of an artery causes it to narrow or become blocked.

6. D. More than 16 million, according to the American Heart Association. In fact, coronary artery disease is the number one killer of both men and women in the U.S.
