Stress Doppler echocardiography in the evaluation of ischemic heart disease.
Doppler echocardiography enables convenient, noninvasive evaluation of global, systolic performance at rest and during exercise. Early studies suggested that Doppler parameters of systolic function were sensitive to exercise-induced myocardial ischemia and could identify patients with severe coronary artery disease. Subsequent investigation, however, has identified several factors in addition to myocardial ischemia that can significantly influence exercise Doppler study results. Thus, in order to obtain reliable information, the many factors that can influence Doppler measurements of aortic flow velocity and acceleration must be accounted for. Further work in this area is likely to produce results that encourage greater application of this technique in experimental and clinical research. At present, the role of stress Doppler echocardiography in the evaluation of ischemic heart disease remains uncertain.
