Study Description
Brief Summary:
Although a number of sophisticated diagnostic tests have been shown to be helpful in identifying patients at high risk for perioperative cardiac complications, no study has addressed the most important question: Should prophylactic coronary revascularization be performed prior to elective vascular surgery? This study is designed to answer this question.
