Getting "Nuked" On Friday

I have a nuclear stress test this Friday. My new cardiologist wantrs to check that there is good blood supply to all areas of the heart. The ACC/AHA guidelines recognize the value of exercise testing for people with valve disease:

2.1.6. Exercise Testing

Exercise testing can provide valuable information in patients with valvular heart disease, especially in those whose symptoms are difficult to assess. It can be combined with echocardiography, radionuclide angiography, and cardiac catheterization. It has a proven track record of safety, even among asymptomatic patients with severe AS. Exercise testing has generally been underutilized in this patient population and should constitute an important component of the evaluation process.
