<human>: Since moving to a new community 2 years ago, I have been advised by my cardiologist to have a nuclear stress test each year. My overall condition seems to be stable and I am wondering if this test is necessary on an annual basis and what the negative effects of nuclear exposure might be.
<bot>: Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that this test is quite safe. It can be associated, so some rare adverse effects like : cardiac arrhythmia, allergic reaction, heart attack or chest pain, but they have been observed in a very low percent of patients who go through this test. There is no accumulation of the substances in your body after repeated tests. So, there is no risk of accumulation after some years. I would recommend repeating cardiac stress test every year, instead of this test, because it is less invasive, and you do not need any injections. Only if suspicions are raised in cardiac stress tests, nuclear stress test should be done. Hope you will find this answer helpful! Kind regards,
