Primary care physicians play a major role in the risk stratification of patients with coronary artery disease (CAD) preparing for noncardiac surgery. Preoperative risk assessment takes into account the type and urgency of surgery and the extent of underlying CAD. With this approach, patients can be categorized as being at high, intermediate, or low risk for postoperative cardiac complications. Judicious use of preoperative noninvasive cardiac testing may help identify those patients at particularly high risk for such complications.
