Which set of symptoms is characteristic of Chronic Heart Failure?

• A. Shortness of breath only
• B. Edema and weight gain
• C. Breathlessness, early muscular fatigue, exercise intolerance
• D. Chest pain with exertion

Answer: (C)

Chronic heart failure limits the heart’s ability to pump blood, which leads to reduced perfusion and fluid buildup. This causes breathlessness, especially with activity, and a noticeable drop in exercise tolerance due to fatigue. The combination of dyspnea, early muscular fatigue, and overall exercise intolerance is the most characteristic presentation because it directly reflects both the lungs' response to impaired circulation and the muscles’ reduced oxygen delivery during activity. Edema and weight gain are common accompanying signs of fluid retention, but they don’t alone describe the typical functional symptoms. Chest pain with exertion points more toward ischemic heart disease than chronic heart failure.
