Patients should discuss this with their referring doctor or the nuclear medicine practice where they will have the test for details. See nuclear medicine for further information about the precautions to take with nuclear medicine studies for breastfeeding patients and those in close contact with children.
Known allergy to any of the pharmacological stress agents is an obvious contraindication.
More specific contraindications for dipyridamole and adenosine:
Caution is exercised when using dobutamine in patients with suspected tendency to ventricular tachyarrythmias and in patients with atrial tachyarrythmias (particularly if not on anticoagulation).
There are no relative contraindications for the NM Cardiac Stress Test. Even in claustrophobic and obese patients, whose weight exceeds the limits of the imaging bed, can be scanned with patient sitting up and 2 dimensional (planar instead of tomographic) images acquired.
The contraindications of the pharmacological stress agents are outlined above.
The likelihood of an adverse reaction to the radiopharmaceutical is very remote, in the order of 1 in 10,000. The likelihood of a serious allergic event is even less likely. The adverse effects of the pharmacological stress agents are outlined above.
The alternatives to NM cardiac stress tests are:
