Abstract:
Physician-supervised exercise testing in asymptomatic patients with aortic stenosis allows an objective assessment of the hemodynamic response to exercise and it provides a measure of exercise capacity. Exercise testing cannot be used to determine the presence or absence of coronary artery disease, but limited data indicate that exercise testing can provide prognostic information. The results of such testing can be used to provide an exercise prescription and to reassure the patient who might otherwise excessively limit his or her activity.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
