What are the risks of an angiogram?
Complications
- kidney damage due to the dye – this is usually temporary.
- a heart attack or stroke.
- damage to a blood vessel, causing internal bleeding – further surgery may be needed to repair the damage.
- a serious allergic reaction to the dye (anaphylaxis), causing dizziness, breathing difficulties or loss of consciousness.

How is chlorine displaced in the dyeing process?
It is readily displaced by the oxygen and nitrogen of ―OH and ―NH 2 groups. Reaction of a dye bearing an amino group with cyanuryl chloride links the two through nitrogen to form the reactive dye. A second chlorine is displaced (in the dyeing step) by reaction with a hydroxyl group of cotton or an amino group in wool.

Who is at risk for developing CIN from dye?
About 2 percent of people receiving dyes can develop CIN. However, the risk for CIN can increase for people with diabetes, a history of heart and blood diseases, and chronic kidney disease (CKD). For example, the risk of CIN in people with advanced CKD (glomerular filtration rate (GFR) below 30 mL/min/1.73m2), increases to 30 to 40 percent.
