Is it okay to drink caffeinated drink before a dobutamine nuclear stress test?

Yes within reason. . The caffeine does not affect the nuclear tracer or the dobutamine. However, most protocols want you to have not eaten or drank for 8 hours. Additionally, in my lab we withhold caffeine from all stress test patients because some of them will need to be converted to other types of stress that can be affected by caffeine. This way all options are available while the patient is present.
Caffeine. Yes. Caffeine can negate the effects of some pharmacologic stress agents such as dipyridamole (persantine) but should not interfere with Dobutamine.

What can you tell me about the cardiolite nuclear stress test?

Myocardial scan. A cardiac perfusion scan measures the amount of blood supplied to your heart muscle. Radiotracers such as thallium or technetium sestamibi (cardiolite) are injected intravenously and travel through blood to heart muscle.2 sets of images are made during rest and exercise and compared. Indications for this study include chest pain, previous heart attack, heart surgery and coronary artery disease. Read more...

My doctor ordered a nuclear stress test but I am concern about the risks and nuclear injection?

Talk to your doc... It is quite normal to be apprehensive about the test and potential side effect of med/material you are given. The substances often used in nuclear stress test is called thallium-201 or technetium-99 radioactive isotopes. The amount used is quite small and long-term cancer risk is less than 1 in 1000 in older adults. I recommend discussing your concern with your doc. Good luck. Read more...
Stress test... There are 2 forms of nuclear stress... Exercise ; pharmacologic. Usually exercise is preferred if possible. Both methods use a tracer such as technetium or thallium to image the heart. You will not feel side effects from the tracer itself however it does expose you to a small amount of radiation. If pharmacologic stress test is performed, you may feel some effects from the pharm agent. Read more...

How important is a nuclear stress test for type b WPW syndrome?

Somewhat. Stress testing, i.e. Exercising while hooked up to an ekg, can be important to see if the extra heart fiber that causes this condition stops conducting at higher heart rates. The nuclear portion, which evaluates for ischemia or lack of blood flow, is not very important. Read more...
