ACC/AHA guideline update for perioperative cardiovascular evaluation for noncardiac surgery—executive summary

These guidelines represent an update of those published in 1996 and are intended for physicians who are involved in the preoperative, operative, and postoperative care of patients undergoing noncardiac surgery. They provide a framework for considering cardiac risk of noncardiac surgery in a variety of patient and surgical situations. The overriding theme of these guidelines is that preoperative intervention is rarely necessary simply to lower the risk of surgery unless such intervention is indicated irrespective of the preoperative context. The purpose of preoperative evaluation is not simply to give medical clearance but rather to perform an evaluation of the patient’s current medical status; make recommendations concerning the evaluation, management, and risk of cardiac problems over the entire perioperative period; and provide a clinical risk profile that the patient, primary physician, anesthesiologist, and surgeon can use in making treatment decisions that may influence short- and long-term cardiac outcomes. The goal of the consultation is to identify the most appropriate testing and treatment strategies to optimize care of the patient, provide assessment of both short- and long-term cardiac risk, and avoid unnecessary testing in this era of cost containment. ### A. Development of Guidelines These guidelines are based on an update of a Medline, EMBASE, Cochrane library, and Best Evidence search of the English literature from 1995 through 2000, a review of selected journals, and the expert opinions of 12 committee members representing various disciplines of cardiovascular care, including general cardiology, interventional cardiology, noninvasive testing, vascular medicine, vascular surgery, anesthesiology, and arrhythmia management. As a result of these searches, more than 400 relevant new articles were identified. In addition, draft guidelines were submitted for critical review and amendment to the executive officers representing the American College of Cardiology (ACC) and the American Heart Association (AHA). A large proportion of the data used to develop these guidelines are …
