To learn more about your condition, your cardiologist may refer you for any of a number of non-invasive diagnostic tests. Non-invasive refers to tests that do not require insertion of diagnostic tubes into the heart or arteries. Here are some examples of tests your cardiologist may request:
- stress (or treadmill) test,
- nuclear stress test (exercise and medication),
- echocardiogram (exercise and medication),
- computed tomography (CT) angiogram scan of the heart arteries,
- positron emission tomography (PET) scan or a magnetic resonance angiography (MRA) scan.
During these tests, you will be attended by technologists or physicians who are specially trained in operating the diagnostic equipment. Your cardiologist - or another cardiologist with special training in interpreting echocardiogram and other images and diagnostic data - will review and analyze your test results. If these test results suggest blockages in your arteries or other problems, your cardiologist may refer you to an interventional cardiologist (a specialist in procedures such as angiograms, angioplasty, and stenting).
