Which of the following is a sign of congestive heart failure?

• A. Shortness of breath
• B. Chest pain
• C. Dizziness
• D. Headache

Answer: (A)

Shortness of breath is a key sign because congestive heart failure means the heart isn’t pumping effectively, so fluid can back up into the lungs and make breathing harder, especially with activity or when lying down. This breathlessness, often described as dyspnea, is a direct consequence of fluid accumulation and reduced oxygen delivery to tissues. Chest pain is more typical of heart muscle oxygen problems, like a heart attack or angina, rather than heart failure itself. Dizziness can occur for various reasons, including medications or blood pressure changes, but it’s not the defining sign of heart failure. Headache is not a characteristic sign of congestive heart failure either. So the presence of shortness of breath directly reflects the fluid congestion and impaired pumping that define congestive heart failure.
