Cardiac stress testing is a test used to measure the heart’s ability to respond to external stress in a controlled environment. The stress response of the heart in the test is induced by exercise, such as treadmill walking or biking, or by mimicked by drugs, such as adenosine, dipyridamole or dobutamine. Exercise is the preferred modality for inducing cardiac stress and increasing myocardial oxygen demand. Two main reasons for a pharmalogical induced stress test are; the patient's inability to exercise adequately because of physical or psychologic limitations; or the chosen test does not go along with exercise (i.e., PET scanning).
