Chemical One Day Patient Instructions

Chemical Nuclear Stress Test (One Day)

Please allow 4 hours to complete this test

This procedure is used as a tool for the detection of coronary (heart) artery disease. In order to obtain the images for this procedure, a small gauge IV will be inserted into either arm or hand. This IV will be used for all medications and nuclear imaging tracers. You will be imaged twice; first is the rest phase of the procedure and then the stress phase. Imaging takes about 15-20 minutes for each set of images. The stress phase consists of an injection of a short acting drug that dilates the coronary (heart) arteries. The diagnostic data obtained is the same as if you were exercising on a treadmill. Occasionally, chest tightness, shortness of breath, head pressure and nausea are felt. However, this sensation should dissipate in a matter of minutes post injection. In most cases, patients are walked on a treadmill very slowly to help minimize the side effects.
