What is the most diagnostic method of defining CAD?
Coronary angiography. During the Coronary angiography, a small catheter is inserted through the skin and into the artery. Guided through the X-ray, the catheter is advanced into the coronary arteries, with the dye injected, and the images produced are called angiogram. The angiographic images reveal the extent and severity of blockages. That is the Gold standard for defining the CAD.
