One of the most controversial to in clinical cardiology is the extent of preoperative studies that is required among patients scheduled for major elective noncardiac operations. Patients in need of an elective operation for either an expanding aortic aneurysm or lower limb ischemia have the highest risk of postoperative cardiac complications because of the high prevalence of coronary artery disease and the hemodynamic stresses associated with the vascular procedures. The decision to perform preoperative coronary angiography should be reserved for only those patients who are deemed clinically unstable or are functionally limited by cardiac symptoms. Among patients with minimal symptoms, preoperative coronary artery revascularization with either coronary artery bypass graft surgery or percutaneous coronary interventions delays the needed operation and does not improve short-term outcomes or long-term survival.
