In suspected decompensated heart failure, which test is NOT part of the initial workup?

• A. Chest X-ray
• B. Cardiac biomarkers
• C. Echocardiography
• D. Coronary angiography

Answer: (D)

When evaluating suspected decompensated heart failure, the aim is to confirm the diagnosis and gauge severity using noninvasive, readily available tests. A chest X-ray helps you see signs of congestion such as pulmonary edema or cardiomegaly, supporting the HF diagnosis. Cardiac biomarkers, including natriuretic peptides, aid in distinguishing heart failure from other causes of dyspnea and can indicate severity, while troponin helps assess for concomitant myocardial injury. Echocardiography is essential because it provides detailed information on ventricular function, valvular disease, and filling pressures, which directly guides therapy.

Coronary angiography, on the other hand, is an invasive procedure used to visualize the coronary arteries and assess for obstructive coronary disease. It is not part of the initial evaluation of suspected decompensated heart failure; it’s reserved for cases where there is a strong concern for ischemia or when revascularization would change management.
