Methods The clinical data of 52 cases of gastrointestinal neoplasms complicated with coronary artery disease admitted from July 2007 to August 2008 at the Affiliated Tumor Hospital of Kunming Medical College were analyzed retrospectively. All the cases had been assessed and managed according to ACC/AHA 2007 Guidelines on Perioperative Cardiovascular Evaluation and Care for Noncardiac Surgery. Results Perioperative managements included revascularization with stents in 5 cases, revascularization with only balloon in 15 cases, systemic medical therapy in 32 cases. Postoperative 30 day complications occurred in 8 cases (15.4%), including acute congestive heart failure in 1 case （1.9%）, acute myocardial infarction and death in 2 cases (3.8%), relapsing angina in 3 cases （5.8%), intractable cardiac arrhythmia in 2 cases （3.8%）. Conclusion Successful perioperative evaluation and management of high risk cardiac cases undergoing noncardiac surgery requires careful teamwork and communication between surgeon, anesthesiologist, cardiologist according to ACC/AHA 2007 Guidelines.
