Dobutamine stress echocardiography combines pharmacologically induced stress with echocardiographic imaging for the diagnosis of coronary artery disease. Dobutamine can create graded levels of stress that mimic physiologic exercise. In the setting of coronary artery disease, stress may lead to ischemia, and subsequently regional dyssynergy which is detectable by echocardiography. Since the stress is pharmacologically mediated, it can be offered to patients who cannot perform adequate exercise. Compared to other currently used imaging techniques, dobutamine stress echocardiography is equivalent in terms of its sensitivity specificity and accuracy. Apart from the diagnosis of coronary disease, dobutamine stress echocardiography has been shown to provide prognostic information.
