Allergic to Angiogram dye?

I had a nuclear scan (MIBI) and a stress test that showed questionable blockage in the left side of my heart. Problem is, is that I am allergic to CT dye which is what they use in an angiogram. Does anybody know any other type of test that can be done to look and see of there is actual blockage.

If you are allergic to CT dye you have an allergy to iodine. There is no reason why you can't have the angiogram (heart cath) . The heart cath is the "gold standard" for diagnosing coronary artery disease.

We do several people in the heart cath lab each month who have iodine allergies. Your cardiologist will premedicate you with something like Prednisone (a steroid) for 2 to 3 days prior to the exam. Depending on the doctor's protocol, when you get there that day, they may give you Tagemet (IV drip), and in the cath lab or before they come get you, they will give you IV Benedryl.

Don't worry, with that pretreatment I have never ,in 20 years, seen anyone have a reaction during or after the heart cath.
Just make sure that whenever you have any type of medical procedure you tell them about your iodine allergy.

I hope this helped and good luck with your procedure....I hope you have a false positive.

No.

You can safely get the cath/CT IF you are properly premedicated.

When I did cardiology, we used prednisone (or another steroid), benedryl, and tagamet/zantac/pepcid.
