Which statement about monitoring LV function after completing therapy is correct?

• A. Not needed
• B. Only during therapy
• C. Only if symptoms arise
• D. Periodic monitoring after completion

Answer: (D)

Monitoring LV function after therapy is important because cardiotoxic effects can appear or worsen well after treatment ends, and patients may have no symptoms early on. Imaging tests such as echocardiography (to measure left ventricular ejection fraction and possibly assess strain) provide a way to detect subclinical decline in heart function before it becomes clinically obvious. Because risk persists or late-onset damage can occur, periodic post-treatment surveillance helps catch changes early and guide management, rather than waiting for symptoms to prompt action. This makes ongoing follow-up the best approach.
