What is the gold standard for diagnosing coronary artery disease?

For diagnosing coronary artery disease, the definitive test is invasive coronary angiography performed during cardiac catheterization. This procedure directly visualizes the coronary lumen with contrast, allowing precise measurement of stenosis and immediate treatment decisions if needed. Noninvasive stress testing looks for ischemia but doesn’t reveal the actual anatomy of the arteries. Echocardiography assesses heart structure and function rather than coronary patency. CT coronary angiography can image the arteries noninvasively but has limitations and isn’t considered the gold standard for diagnosing CAD in all patients because of radiation, contrast use, and some diagnostic accuracy concerns.
