Preoperative Dipyridamole Thallium Imaging and Ambulatory Electrocardiographic Monitoring as a Predictor of Perioperative Cardiac Events and Long-term Outcome

Abstract
Background: Dipyridamole thallium imaging (DTI) and ambulatory electrocardiography (AEGC) have been advocated as means to stratify risk before vascular surgery. The purpose of this study was to compare the predictive value of both tests in noncardiac surgery patients for perioperative cardiac morbidity and long-term mortality.
