title: Clinical determinants in perioperative cardiac evaluation.
abstract: Perioperative cardiac events are the largest cause of morbidity and mortality for patients undergoing elective surgery. As a result, numerous recent studies have focused on attempts to identify patients at increased risk for perioperative events. These have delineated testing modalities capable of identifying high-risk patients, and clinical markers which further stratify patients facing elective surgery into high-, medium-, and low-risk subgroups. In this article, the authors review the evidence supporting the use of clinical markers of risk to evaluate patients before elective surgery. The role of preoperative clinical assessment in identifying patients most likely to benefit from further testing or intervention, (ie, those at significant risk for short- and long-term cardiac events) is stressed. Assessment and intervention for risk factors of long-term cardiac disease is also stressed, as the preoperative evaluation represents an opportunity for improvement in the short- and long-term cardiac risk profile. Finally, the algorithm for preoperative cardiovascular evaluation published jointly by the ACC/AHA joint taskforce on practice guidelines is reviewed. This algorithm is a synthesis of the current literature, into a cost effective and efficient approach to patient evaluation.
