Nuclear stress test - do I need it?

[Taffy779]

I am 75 and Type 2 diabetes, under control. I have no cardiac symptoms. My electrocardiogram and Echo (sono) were fine. I have no heart pains. I am having a hip replacement. I will have a epidural and some pills for anesthesia. I am not required by the hospital to have cardiac clearance. Some rheumatologist at the hospital recommended I have a nuclear stress test before the surgery. I asked her why. She said my age, my diabetes and something else. Maybe family history. My father and his brother had heart trouble at a young age. I went to a cardiologist and he thought it was a good idea. I really do not want to have this test. Do I need it? I know it is precautionary but is it really necessary? I have so much pain and my other hip hurts so I may need to have that hip done down the line. It seems the immediate issue is my hip. I do not want to stir up troubles and wonder if this test is just drumming up more business for the doctor.

I don't believe there is any radiation in the scan.  The dye that is injected (Cardiolite) is  radioactive.  However, the type of material is exceptionally safe and poses virtually no short or long term risk, and it is quickly expelled by your body.  I wish you a speedy recovery with your hip replacement.

Thanks for responding.I am afraid of all of the radiation involved.

    A nuclear stress test is usually done by getting your heart rate up to a desired level by treadmill exercise, then having a scan done by an MRI type machine specifically designed for that purpose.  If you are unable to do the treadmill, then they will probably inject you with a drug that will cause your heart to temporarily speed up.  It can be a little uncomfortable when the scan is being done because you will be required to lie still for 30-40 minutes.   It is a painless procedure, however.  
   No doubt, given your age in particular, the doctors don't want any surprises when you are going to have a hip replaced.   Please regard the caution your doctors fare exercising about your treatment as a good thing.
