Stress tests are tests performed by a doctor and/or trained technician to evaluate the cardiovascular system during a period of exercise and increased demand. This test measures exercise capacity and identifies abnormal responses to exercise.
Stress Testing will be performed upon written order by a Physician or Health Professional Affiliate (HPA).
Cardiac Exercise Stress Testing
Cardiac Stress Testing Most patients will walk on a treadmill. For those patients who are unable to walk on a treadmill, there is also the option of using an exercise bike.
Patient Preparation: Wear comfortable clothing and sneakers or walking shoes as you will be walking on the treadmill. Do not drink or eat foods containing caffeine for 12 hours before the test. Caffeine will interfere with the results of your test. The test takes about 30-45 minutes.
Nuclear Stress Testing
Blood flow to the heart muscle is pictured using a radioactive substance (radio-isotope) known as a tracer (*this is not a dye*). There are two types of Nuclear Tests (Exercise and Chemical)
For either type, an IV will be started so that the tracer can be administered. Next, resting images will be taken of your heart. If you are having a Nuclear Exercise Stress Test, you will then walk on the treadmill just like you would with a regular stress test. If you are having a Chemical Stress Test you will be given a medication which dilates the arteries in the heart, mimicking exercise. A second set of images will then be taken of your heart, which will be compared to the resting images to see if there are any changes.
