For a patient experiencing chest pain when walking, what is the next step in management?

• A. Coronary angiography
• B. Exercise stress test
• C. Medication adjustment
• D. CT angiography

Answer: (B)

When a patient presents with chest pain during exertion, such as walking, it raises the suspicion of potential coronary artery disease (CAD) or ischemia. The next appropriate step in management is to assess the functional capacity of the heart and its response to stress, which is effectively evaluated through an exercise stress test.

An exercise stress test involves monitoring the patient's heart while they engage in physical activity, usually on a treadmill or stationary bike. This test can help determine if the chest pain is indeed related to inadequate blood flow to the heart muscles during an increased demand for oxygen. The outcome will guide further management, such as the need for coronary angiography if the test indicates significant ischemia.

While coronary angiography could provide direct visualization of the coronary arteries, it is typically reserved for cases where there is a clear indication of significant obstruction or if non-invasive tests suggest a high likelihood of severe coronary artery disease. Similarly, adjusting medications might be necessary based on findings, but it generally follows initial diagnostic testing. CT angiography could also visualize coronary artery anatomy but is less commonly used as an initial management step compared to an exercise stress test.

Thus, performing an exercise stress test is the logical next step in evaluating the cause of the patient's symptoms and deciding the most appropriate management
