    Reaction to Lexiscan
    bearhugs_n_kisses posted:
    I need healp on how to address this with my cardiaologist. I had a nuclear stress test done on Thursday. I had a very bad reaction the the Lexiscan. My BP went way up, I got sick to my stomach, flushing from toes to head, a terrible headache, my heart was racing and frankly I thought I was going to die. This was a very frighten experince. These symptoms continued for about 10 min except for the terrible headache with lasted 2 days. After the stress test was comlpeted and the pictures were taken I was approached by two Dr.s and asked to come in the back. I was informed there was a problem with the radiotracer dye that is was a BAD BATCH ( quote) and they were no able to get good pictures and that I would have to come back tomorrow (Friday) to repeat the entire test from bigining to end. By the look on my face the Dr.s could tell somethimng was wrong. One of them said to me " Well it is not like we are inconviencing you- you need to come back tomoroww anyway to complete the test. ( no one told me this wa a two day test) I said I am reacting to one the fact you just told me this was a bad batch of dye and 2 to the reaction I had to the Lexicam and that I do not want to go thru that again. They were obviously not told of my reaction as the response to me was " well that only lasted about a minute didn't it?" I said NO. it took about a minute to work but my reaction lasted about 10 mins and I still am not feeling well. The receptionist blurred out to the Dr. "but this is a two day test" the Dr. said we will comlpete it all in one day. ( funny how that changed) Anyway, I left to beging my 2 and a half hour drive back home and was so ill I didn't think I was going to make it. I was to ill to make the 5 hour trip again the next day to do this all over again and have continued to be ill all weekend till now with headache, gastrointestinal issues and exhaustion. I was not even able to call the nuclear med depaertment to tell them I could not make it there to redo the test. Also I live on a fixed income and have to plan for every penny spent. 2 trips in t days is an extra 100.00 in gas for me. This whole thing has caused me such stress and I don't know how to address this with my cardilogist who I just met for the very first time. The day I met him he ordered an echocardiogram, EKG and a ton of blood work. I had these all done that day. Then a week later went to have the stress test done. I have a tendency to respond with emotion and write or say to much instead of staying with the facts. I connot go thru that again. I cannot trust the same thing won't happen to me. And I can't believe they told me they gave me a "bad batch "of dye. I don't know if I should call, write or email my cardiologist and what exactly I should say. Can you help me? Thank you Tammy

    Hi Tammy:

    A very frightening experience no doubt.

    Some years ago, my father had a persantine/thallium stress test, and never made it to the nuclear scan part, as the persantine (stressor agent) damn-near killed him (caused the worst chest pain ever), and he already had coronary artery disease, multi-vessel bypass and several angioplasties.

    "I cannot go thru that again."

    Perhaps a different pharmacological stress agent would make a world of difference, or if not, perhaps you could inquire about a non-invasive 64-slice Cardiac CT scan (heart scan), which doesn't require the heart to be put under stress, physically, or stressor agent-induced, which as reported, allows doctors to view/examine the heart and the coronary arteries in never-before-seen detail.

    Much better yet though, as reported, and as available, the new 320-slice Cardiac CT scanners can measure subtle changes in blood flow, or minute blockages forming in blood vessels, no bigger than the average width of a toothpick (1.5 mm) in the heart, and the brain. Also as applicable, as availablem there is non-invasive Cardiac MRI (a "heart-specific" magnetic resonance imaging technology).

    ALWAYS be proactive in your health care and treatment. Sometimes this requires being assertive. Most important, communicate/interact well with your doctors. Best of luck down the road of life.

    Take care,

    Regarding the "bad batch" of radiotracer, just curious as to which specific type were you given?

    A shortage of a radioisotope used in performing nuclear stress tests.


    Medical isotope shortage threatens treatments - 8/14/09

    The shutdown of a nuclear reactor in Canada has caused a shortage of a radioactive isotope used to detect cancers and heart disease, forcing doctors into costlier procedures that can be less effective and expose patients to more radioactivity.

    Some 16 million people in the United States, 40,000 patients each day, undergo medical imaging procedures using the isotope, technetium-99. Eighty percent of nuclear medicine scans use it.

    ☞A little over half of technetium-99 used in the United States goes for heart imaging.......

    Hi CardioStar, Thank you so much for your response and all the information you shared. I read it all. This is all new to me and now I know I have options and what they might be. This will be helpful when my cardiologist and I decide what the best next step will be. Thank you again Gratefully Tammy
    bearhugs_n_kisses responded:
    Cardiostar, I do not know what I was given as the radiotracer but I was told they were going to make up "a new batch" for me the next day. After reading your info about the shortage and that it had to be made daily because it only lasts 6 to 12 hours it could have very well have been the problem. Thanks Again Tammy
