An angiogram is the injection of a special dye into the heart or its blood vessels that shows up on an x-ray. The procedure identifies any blockage in the coronary arteries, the blood vessels that supply the heart. The angiogram can also show how the heart is beating and how the blood flows through the heart. There may be some bruising or discomfort at the site of the catheter entry. Cardiac catheterization and angiogram are safe procedures with minimal risks.
Some people can be allergic to the dye used during an angiogram.
If you have ever had a reaction to a test that involves x-ray dyes, even a gall bladder test, you should tell your healthcare provider. If you or someone in your family needs one of these tests, ask your healthcare provider to discuss the risks and benefits of the test with you. All Rights Reserved.
