Abstract
Stress echocardiography has become a valuable clinical tool in recent years. Different forms of cardiovascular stresses, ranging from treadmill exercise to pharmacologic agents, may be coupled with two dimensional echocardiography to accurately assess the presence and significance of coronary artery disease. Stress echocardiography also provides important prognostic and diagnostic information in a variety of clinical settings such as after myocardial infarction, before noncardiac surgery, and postrevascularization with bypass surgery or coronary angioplasty. In patients unable to exercise, pharmacologic stress echocardiography using dobutamine, dipyridamole or adenosine may be used. When compared with thallium imaging, stress echocardiography has a comparable accuracy for the detection of coronary artery disease, safer risk profile, and lower cost, and may represent the ideal form of noninvasive imaging for coronary disease.
