Objective: the objective of this Project is to review the indications, protocols and applications of the stress echocardiogram. methods and materials: research on the following words was done in the PUBMED/Medline, Cochrane, SciELO databases, as well as in references in journal articles and texts mainly from texts from the last five years in English and in Spanish: stress echocardiogram, effort echocardiogram and pharmacological stress test. The result of this search returned 203 references, 46 of which were taken as the most relevant, taking into consideration mainly, meth analysis, revision articles, state of the art, random studies, DOBLE CIEGO, and clinical guides. Results: The data obtained from the regional ventricular function in the maximum peak of exercise, are important predictors of cardiac events; this, in addition to all of the clinical variables during patient follow up. A score of parietal motility, higher than 1.4, or a ejection fraction lower than 50%, imply a significant adverse forecast. On the other hand, the myocardiál an viábility indicators, through the pharmacologic stimulus of the myocardium, predict the recovery of the cardiac function after revascularization procedures. Conclusion: The stress echocardiogram (ECO) is a complementary technique, useful for the diagnose and forecast fo patients with coronary disease. The principles of its use consist on the basics that upon the creation of ischemia, an alteration in the distal parietal motility will be produced to the obstructive coronary injury. Furthermore, it can be used to evaluate the severity of a vulvopathy and to establish the diagnose of the hidden pulmonary hypertension.
