Which test is NOT used to diagnose heart failure?

• A. Echocardiogram
• B. Brain natriuretic peptide (BNP) blood test
• C. Nuclear stress test
• D. Holter monitoring

Answer: (D)

Diagnosing heart failure relies on assessing how well the heart pumps and its structure, along with biomarkers of myocardial stress. An echocardiogram visualizes chambers and valves and measures ejection fraction, giving direct information about pumping function. BNP or NT-proBNP rises with ventricular stretch and helps confirm HF in the right clinical context. A nuclear stress test evaluates blood flow and scar in the heart and can reveal ischemia or viability that contributes to HF. In contrast, Holter monitoring tracks the heart’s electrical activity over 24-48 hours to detect arrhythmias and rhythm problems; while valuable for rhythm management, it does not assess pumping function or cardiac structure, so it is not used to diagnose heart failure.
