BASIC PROCEDURES: The study included 175 patients who presented to the ED with chest pain and underwent EST between January 1, 2005, and November 30, 2006. MAIN FINDINGS: After the EST, 113 patients were discharged, and 62 were admitted. Exercise stress testing's positive predictive value for coronary artery disease among admitted patients was 35.7%, and sensitivity was 95.2%. Exercise stress testing's negative predictive value among discharged patients was 99.1%. None of the 113 discharged patients returned to the ED for cardiac reasons during the 30-day follow-up period. PRINCIPAL CONCLUSION: A chest pain unit or a parallel facility for evaluating patients with chest pain and with low risk for active coronary disease is necessary for detecting low-risk patients who eventually need cardiac intervention. 收起
