Which test is not used to confirm typical stable ischemic heart disease?

• A. Exercise treadmill testing
• B. Resting ECG
• C. Stress imaging
• D. Coronary angiography

Answer: (D)

The test is about how we diagnose typical stable ischemic heart disease and which tests demonstrate ischemia versus anatomy. In stable ischemic heart disease, we first look for evidence that the heart muscle experiences ischemia under stress. Exercise treadmill testing can show inducible ischemia by revealing symptoms or ECG changes during physical stress. Resting ECG provides baseline information but cannot confirm ischemia on its own. Stress imaging, using nuclear perfusion or stress echocardiography, directly visualizes perfusion or wall‑motion abnormalities that occur with ischemia, increasing diagnostic accuracy when the pretest probability warrants it. Coronary angiography, however, is an invasive procedure that maps the anatomy and severity of coronary artery blockages. It confirms the presence of coronary lesions but does not by itself prove ischemia; it’s typically reserved for cases where noninvasive tests indicate ischemia or high risk and when revascularization planning is considered. So coronary angiography is not used to confirm typical stable ischemic heart disease in the initial diagnostic sense.
