For suspected heart failure, which initial tests are recommended before echocardiography?

• A. EKG, CXR, and BNP
• B. EKG alone
• C. BNP alone
• D. Echo first

Answer: (A)

When heart failure is suspected, start with a rapid, practical workup that can be done quickly and guide urgent management while echocardiography is arranged. An electrocardiogram helps detect rhythm problems, prior myocardial infarction, or conduction abnormalities that influence treatment. A chest X-ray assesses heart size and signs of pulmonary edema or other lung issues that can mimic or accompany heart failure. BNP (or NT-proBNP) testing adds a biochemical sense of volume overload and supports or argues against heart failure in the right clinical context. Using these together provides a fast, complementary picture: ECG shows electrical and ischemic clues, CXR shows structural and pulmonary involvement, and BNP offers a biochemical signal of HF. Echocardiography remains the definitive test to quantify heart function and structure, but it is appropriate to obtain after or alongside these initial studies to guide immediate decisions. BNP can help, but it’s not perfect—values can be affected by age, kidney function, obesity, and other conditions—so it must be interpreted with the overall clinical picture.
