Allergic to Angiogram dye?

Question

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.

Answer 1

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.

Answer 3

i'm going to start up via asserting something is conceivable and not something is without some threat. in spite of this, that is amazingly not likely that the angiogram triggered the guts attack till it exceeded off interior a week of the technique on the main. An angiogram consistent with se does not contain any stretching of an artery - if it did, then you definately had an angioplasty meaning you had blockage at that ingredient. So how can a common angiogram quite a few months till now consequence in a heart attack now? that is definitely generic that categorical volatile plaques, with skinny fiborous caps and lipid cores, can rupture and reason a severe acute experience (heart attack). The rub is that on angiogram those lesions oftentimes are 30-40% blockages that doesn't in any different case warrant corrective scientific care. this could be a failing it fairly is being studied. sometime interior the destiny we'd have imagining which will supply us a flow component of the lesions - to renowned that are severe threat and that are actually not. i wish this facilitates. solid luck.

Answer 4

I, too am allergic to iodine and was pre medicated before an angiogram with horrific results. I was just given prednisone the night before and the morning of but still went into anaphylaxis. I spent several hours in the hospital being treated with Benadryl and prednisone but had to return to the ER with the same symptoms and more treatment. I will never trust another doctor to pre treat me for this allergy as death is preferable to what I went through. Ask questions and be thorough with those questions!

Answer 5

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.
