title: [Controversies in stress echocardiography: the indications, diagnostic accuracy and stratification of dobutamine stress echocardiography].
abstract: In recent years, stress echocardiography has become a valuable tool in the diagnosis, stratification and prognostic evaluation of coronary artery disease. Stress echocardiography has been performed with a variety of methods, including exercise, atrial pacing and pharmacological stress with the use of adenosine, dipyridamol and dobutamine. Either of these modalities of stress echo are a good choice in the evaluation of ischemic disease and the selection of one over another should depend on the patient's characteristics, experience of the stress echo laboratory and clinical needs (in the detection of viability there is greater experience in the use of dobutamine making this the most popular choice when evaluating myocardial hibernation). The aim of this paper is to review the indications, diagnostic accuracy and prognostic stratification of dobutamine stress echocardiography, comparing them with those obtained with other stress echo modalities and with nuclear techniques.
