Which statement describes late symptoms of chemotherapy-related cardiotoxicity?

• A. Shortness of breath at rest
• B. Progressive dyspnea, lower limb edema, persistent fatigue
• C. Chest pain during activity
• D. Headache

Answer: (B)

Late chemotherapy-related cardiotoxicity tends to show signs of heart failure from damaged heart muscle. The best description matches gradual shortness of breath with activity (dyspnea on exertion), swelling in the legs (edema) from fluid buildup, and ongoing fatigue due to the heart not pumping effectively. These symptoms reflect chronic congestion and reduced cardiac output that develop over time after exposure to cardiotoxic agents. Chest pain during activity would point more to ischemia or angina rather than a late pattern of heart failure. Shortness of breath at rest can occur in more advanced decompensation but is not the typical late pattern, and headache is not a characteristic sign of chemo-induced cardiotoxicity.
