Guest guest Posted April 2, 2006 Report Share Posted April 2, 2006 Hi Friends, I have to have a chemical stress test for heart function. Has anyone had any problems with this? Is there anything that I should be concerned about? Cheers, Ruth Quote Link to comment Share on other sites More sharing options...
Guest guest Posted April 3, 2006 Report Share Posted April 3, 2006 Hi Ruth I had one a couple of months ago, no problems. I had somehow been led to understand that the adenosine would somehow MIMIC a real exercise stress test. Instead, I was asked to do a treadmill anyway, and the effects of the IV-administered adenosine stunned me. The complete depth of exhaustion I felt, induced by the chemical, was amazing. I instantly felt wobbly and weak, and had a powerful need to gracefully sit down before I fell down. But the techs encouraged me to keep slowly plodding along as best I could on the treadmill. The best part was that the effect only lasted maybe 15-30 seconds, and I was " better " , relatively speaking. Then I was told this would be repeated, and I somehow managed to get through it. Later, I felt so DRAINED, it was like I had climbed a huge cliff. I don't mean to scare you, just to let you know something that should maybe be obvious (but was a surprise to me). The adenosine doesn't MIMIC vast exhaustion, it CAUSES it. The advantage is that you don't have to seriously treadmill to get the effect. But the effect is still there. If you're anything like me, be prepared for a SERIOUS need to rest afterwards, possibly much more than is typical. Otherwise, the test is a piece of cake. :-) Notice that " adenosine " above is the same as in " adenosine tri-phosphate " (ATP), the central storage engine of the electron transport chain. So I'm guessing that this chemically induced exhaustion has its mechanism in mitochondria. Steve D. Chemical Stress Test Hi Friends, I have to have a chemical stress test for heart function.

Guest guest Posted April 3, 2006 Report Share Posted April 3, 2006 Hi Ruth, It is great to hear from you. I have had it and I myself got very sick to my stomach and had lots of vomiting after and nausea during. I have been advised to use Tigan before the test next time.

Guest guest Posted April 8, 2006 Report Share Posted April 8, 2006 I was scheduled for the chemical stress test, and at the last minute changed to the treadmill only test. I ended up thinking that strenuous exercise under my own body's control would be preferable to the chemical method. YMMV, but I'm a bit leary of any medicines, as some seem to affect me differently. But the stress test is done with a cardiologist present, so that should give you some peace of mind.

Guest guest Posted April 9, 2006 Report Share Posted April 9, 2006 This sounds similar to the one I had which was called a thallium perfusion study - twas after I had had a heart attack and they didn't want to take the chance of giving me a treadmill. i absolutely hated the feeling - had to lie completely still while they pushed all the chemical through my veins - made me feel nauseated and kind of nervous as in jumpy through my whole body. I was glad when it was over, but I felt fine once it was over. pamela From: ohgminion To: Sent: Sunday, April 09, 2006 6:05 AM Subject: Re: Chemical Stress Test I was scheduled for the chemical stress test, and at the last minute changed to the treadmill only test.
