What are late symptoms of chemotherapy-related cardiotoxicity?

• A. Shortness of breath at rest
• B. Progressive dyspnoea, lower limb oedema, persistent fatigue
• C. Chest pain with exertion
• D. Palpitations

Answer: (B)

Late chemotherapy-related cardiotoxicity often shows up as heart failure years after treatment. The best answer captures the gradual, functional decline typical of this effect: increasing trouble with daily activities due to shortness of breath on exertion, fluid buildup causing leg swelling, and persistent fatigue. These symptoms reflect the heart’s reduced pumping ability and volume overload that develop over time.

Shortness of breath at rest suggests more acute decompensation rather than the slow, late pattern. Chest pain with exertion points to ischemia, not specifically to timing of cardiotoxicity. Palpitations can occur with rhythm problems but aren’t the hallmark late signs of this toxicity.
