Which test is routinely included in the initial evaluation of heart failure alongside imaging?

• A. EEG
• B. CBC/CMP
• C. Urine culture
• D. Skin biopsy

Answer: (B)

In heart failure workup, imaging shows the heart’s structure and function, but routine blood tests are essential to understand how the body is handling the condition and its treatment. A CBC/CMP provides this critical information: the CBC screens for anemia or infection that could worsen symptoms, while the CMP assesses kidney function, electrolytes (like potassium and sodium), and liver enzymes. Kidney function and electrolytes are especially important because diuretics, ACE inhibitors, and other HF therapies can alter them, so having a baseline helps with safe dosing and monitoring. This mix of imaging plus CBC/CMP is a standard part of the initial evaluation to guide management. The other options don’t fit as routinely in this context. EEG checks brain activity and isn’t useful for HF management; urine culture is specific for infection unless indicated, not a general HF workup; skin biopsy has no role in assessing heart failure.
