In inability of pathologic myocardium to augment function during stress is the cornerstone of stress echocardiography for both ischemic and non-ischemic disease. The time-course, extent and spatial distribution of abnormal wall motion abnormalities are markers of the severity of the underlying pathology. Potential confounders of this association of disease and abnormal function are the nature (and adequacy) of stress, the quality and timing of image acquisition, and the sensitivity and reliability of the diagnostic criteria. This chapter reviews the selection and performance of stress modalities, details of image acquisition and approaches to interpretation and reporting. The evidence-base for the accuracy and prognostic value of stress echocardiography is summarized, and its role, relative to other imaging approaches is discussed.
