When can cardiac damage from anthracycline exposure present?

When can cardiac damage from anthracycline exposure present?

• A. During treatment or years after completion
• B. Only during treatment
• C. Only after completion
• D. Never

Answer: (A)

Cardiac damage from anthracyclines can show up both during treatment and many years after therapy ends, not only at one time. This happens because the drug’s effect on heart cells is dose-related and can cause immediate injury as treatment proceeds, while also causing long-term changes that may gradually develop into cardiomyopathy long after exposure. So patients can present with heart problems while still receiving the drug or years later, underscoring the need for ongoing cardiac monitoring even after therapy stops. The other options miss either the early window, the late window, or both, and are therefore not accurate.
