Dobutamine stress echocardiography: a new, noninvasive method for detecting ischemic heart disease

Pharmacologic induction of exercise with dobutamine hydrochloride, coupled with the technology of echocardiography, is an alternate method for evaluating ischemic heart disease. Dobutamine stress echocardiography involves obtaining echocardiographic images before, during, and after a titrated dobutamine infusion is administered. The study is positive if global or regional ventricular wall motion abnormalities develop. With our changing health care environment, this cost-effective, noninvasive diagnostic procedure is becoming a standard for determining the presence of coronary artery disease in those individuals who are unable or unwilling to undergo exercise stress testing.
