Angiography is a kind of X-ray used to check blood vessels. Blood vessels do not display clearly on a normal X-ray, so a special dye requires to be injected into your blood first. This highlights your blood vessels, enabling your doctor to see any problems. The X-ray images produced during angiography are called angiograms.
Your doctor may recommend that you should have Angiography if you have:
- Chest pain
- Pain in your jaw, neck or arm that can’t be explained by other tests
- New or increasing chest pain
- A heart defect you were born with
- Abnormal issues on a noninvasive heart stress test
- Other blood vessel difficulties or a chest injury
- A heart valve problem that requires surgery
Angiography (CAG)- Procedure
Before your angiogram method starts, your health care team will examine your medical history, including allergies and medications you take. The team may do a physical exam and check your vital signs — blood pressure and pulse. You’ll also empty your bladder and switch into a hospital gown. You may have to remove contact lenses, eyeglasses, and hairpins.
