Clinical Application of CHD

Coronary angiography is currently a common and effective method for diagnosing coronary atherosclerotic heart disease (CHD). Selective coronary angiography is to use an angiography machine to percutaneously puncture the femoral artery of the lower extremity through a specially designed cardiac catheter, retrograde along the descending aorta to the root of the ascending aorta, and then explore the left or right coronary artery for insertion and inject contrast agent in order to visualize the coronary arteries.

Find out whether there are stenotic lesions in the blood vessels, make a clear diagnosis of the lesion location, scope, severity, and condition of the blood vessel wall, and decide on the treatment plan (intervention, surgery or medical treatment). This is a relatively safe and reliable invasive diagnostic technique, which has been widely used clinically and is considered to be the "gold standard" for the diagnosis of coronary heart disease.
