If you are pregnant or suspect that you may be pregnant, you should notify your physician due to the risk of injury to the fetus from radionuclide angiography. Radiation exposure during pregnancy may lead to birth defects. If you are lactating or breastfeeding, you should notify your physician due to the risk of contaminating breast milk with the radionuclide.
Patients who are allergic to or sensitive to medications, contrast dyes, iodine, or latex should notify their physician. There may be other risks depending upon your specific medical condition. Be sure to discuss any concerns with your physician prior to the procedure. Nicotine in cigarettes may cause spasm in the coronary arteries, which could affect the test results.
