I had a kidney transplant 5 years ago. I saw a cardiologist today that wants to do a nuclear stress test. I thought radioactive dye was bad after a kidney transplant?

A nuclear cardiac stress test does not have any kidney toxicity and should be safe for a person with a kidney transplant. Iodine containing contrast used for cardiac catheterization can be toxic to the kidney, so if the stress test is abnormal, then a cardiac catheterization may be the next procedure suggested. You may have to consult with your transplant nephrologist, if a heart catheterization is recommended.
