Which statement best defines congestive heart failure?

• A. A condition in which the heart beats irregularly.
• B. A chronic condition in which the heart doesn't pump blood as well as it should.
• C. A sudden blockage of a coronary artery causing a heart attack.
• D. A disease of the heart valves that causes a murmur.

Answer: (B)

Congestive heart failure is a chronic condition in which the heart doesn’t pump blood as well as it should. When the heart’s pumping ability is reduced, organs don’t get enough oxygen-rich blood, and blood can back up in the lungs and other tissues, causing fluid buildup and symptoms like shortness of breath, fatigue, and swelling. The term “congestive” highlights that fluid congestion effect. This statement is the best definition because it captures both the ongoing nature of the problem and the inadequate pumping that leads to systemic and pulmonary congestion. It’s not about the heart beating irregularly, which would describe an arrhythmia; it’s not about a sudden artery blockage causing a heart attack; and it’s not specifically about a heart valve disease with a murmur. Those are different conditions, although they can occur alongside heart failure.
