Coronary angiogram

What is a coronary angiogram?

A coronary angiogram is a test used to look at the main arteries that supply the heart with blood and oxygen, known as the coronary arteries. This test shows your doctor the exact location and seriousness of any narrowed areas in your coronary arteries..

During the test, a thin plastic tube called a catheter is inserted into a blood vessel through a small cut in your groin or wrist. Using X-ray, the catheter is directed through your blood vessels to your heart. A special dye is then injected through the catheter so the arteries can show up clearly on an X-ray.


The test can also give information about the blood pressure inside your heart and how well your heart is pumping. Your consultant can use this information to help decide on your treatment. 


A coronary angiogram is also called an angiogram or a cardiac catheterisation.
