Why can't I have caffine 24 hrs prior to a stress test?
I'm having a stress test tomorrow morning at 8am. I was supposted to stop all caffine 24 hours prior to the test but forgot and drank coffee until 10am today will that be ok?
Because it will disrupt your system and not give an accurate reading. To put it in the simplicist terms
because it drives up your blood pressure, and could give false returns on a stress test. tell doc howmuch coffee you had, and they can figure that into your results
it raises your blood pressure
yeah, its only 2 hours short of 24 hrs you should be fine. if it concerns you though mention it to the doc. anyway, caffeine effects how hard your heart works and raises blood pressure so it can alter the test results
I think you should mention that to the Doc before the test. Caffeine elevates heart rate.
Because caffeine raises blood pressure and will affect your test. Your test will not be accurate if you drink coffee within that time. That's why they tell you not to drink any caffeine.
if your doctor has told you to stop drinking coffee prior to TMT ,you have to follow his orders.there is some reason behind it.drinking coffee may alter your BP and pulse rate which will give you false positive reports.
No caffeine, no smoking it all has to do with your heart rate & blood presure,and ekg. Tomorrow if your walking the treadmill no caffine after midnight I tell my patients.Also nothinh to eat or drink 2 hours before your appt.If your not walking the treadmill caffine is bad if you are having a chemial stress test using persantine,adenosine,dobutamine because you may have reaction with the medication they will inject to speed your heart rate up as if you were walking.Make sure you tell the Cariologist how you feel at all times if you are feeling any sob ,chest pain or fatigue so your dr can document how you are feeling.Cardiologist, and ekg tech will be monitoring you the whole time. Hope I could help nuclear medicine tech asst.
