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.
