Which diagnostic test is used to evaluate heart failure?

• A. CT angiography
• B. Endoscopy
• C. Echocardiogram
• D. MRI

Answer: (C)

Evaluating heart failure hinges on seeing how the heart is pumping and filling, and whether there are structural issues like valve problems. An echocardiogram uses ultrasound to visualize the heart in real time and provides essential information: left ventricular ejection fraction to distinguish reduced vs preserved ejection fraction, chamber sizes, wall motion, valvular function, and estimates of filling and pulmonary pressures with Doppler. This combination makes it the best, most informative, and most accessible test to diagnose heart failure, guide treatment decisions, and monitor response. Other tests have important roles in specific situations, but they aren’t first-line for evaluating heart failure. CT angiography maps coronary arteries or detects a pulmonary embolism, not heart failure mechanics. Endoscopy has no relevance to cardiac function. MRI can offer detailed tissue characterization and is used in certain complex cases, but it’s less readily available and slower, so echocardiography remains the initial go-to study.
