Prognostic value of dobutamine-atropine stress echocardiography for peri-operative and late cardiac events in patients scheduled for vascular surgery.

Abstract

Cardiac events in the peri-operative phase and late after non-cardiac vascular surgery are a major cause of morbidity and mortality. Numerous tests and diagnostic strategies--usually consisting of a combination of analysis of clinical risk factors and additional non-exercise dependent stress testing, such as thallium scintigraphy, or stress echocardiography--have been developed to preoperatively identify patients with increased risk. The tests ideally should identify three subpopulations in a group with a high prevalence of coronary artery disease; (1) low-risk patients who can be referred for surgery without extra cardiac intervention. (2) patients whose peri-operative cardiac risk outweighs the potential benefits of vascular surgery, (3) patients whose risk may be reduced by peri-operative therapeutic interventions. This review will discuss the prognostic value of dobutamine stress echocardiography for risk stratification in patients scheduled for non-cardiac vascular surgery and discuss guidelines for future management.
