Exercise Stress Testing
What is the purpose of an exercise test?
Exercise testing is used to:
- Confirm the diagnosis of coronary disease or angina
- Follow the progress of coronary disease
- Evaluate respiratory function
- Aid in the detection of exercise induced asthma as well as restrictive and obstructive lung disease
- Predict the risk of further heart problems
- Help evaluate response to treatment
How accurate is the exercise test?
The exercise test is not a perfect test. Some people with disease will have a normal test and some healthy people will have an abnormal test.
The accuracy of a cardiac exercise test can be improved in two ways. One way is by performing an echocardiogram at rest, before the exercise test, and again immediately following the exercise test. If there is coronary artery narrowing, the images just after exercise may show abnormal heart function. A second method to improve the exercise test is by injecting a small amount of a radioactive (nuclear) tracer into a vein in your arm. The tracer can indicate areas of the heart that do not receive adequate blood flow. Typically there are two injections, one at rest and the other at the peak of exercise.
There are options for the exercise portion of the test as well. Most of the time, your IHLA physician will like to have you walk on a treadmill. For the Cardiopulmonary Exercise Test (CPX), the exercise portion is typically performed on a bicycle ergometer. However, if you are physically unable to use either of these pieces of equipment, there are medications that we can use to simulate exercise. Your physician will discuss these choices with you, prior to your test.
