Which of the following tests will best evaluate the extent of Mr. Cetaine's coronary artery disease?

• A. Chest X-ray
• B. Cardiac ultrasonography
• C. Electrocardiography (ECG)
• D. Angiography

Answer: (D)

To determine how extensive coronary artery disease is, you need direct visualization of the coronary arteries to see where narrowing occurs and how severe it is. Coronary angiography achieves this by injecting contrast dye into the coronary vessels and taking X-ray images. It maps every major artery, shows the location and degree of stenosis, and reveals multi-vessel involvement or occlusions. This detailed picture is essential for planning revascularization options like angioplasty or bypass surgery. Other tests don’t provide the same level of anatomical detail. A chest X-ray can show heart size or edema but not the specific coronary anatomy. Echocardiography assesses heart structure and function, including wall motion, but doesn’t reveal the actual coronary artery blocks. An electrocardiogram detects electrical changes related to ischemia or infarction, but it doesn’t show which arteries are narrowed or by how much. So, the test that best evaluates the extent of coronary artery disease is angiography.
