Coronary CT angiography for patients with stable chest pain in the Emergency Department; an appraisal of current and emerging evidence

摘要

The recent Medicare reimbursement of coronary computed tomographic angiography (CCTA) reflects the potential of this technology to result in significant cost-savings and improved management of patients with coronary artery disease, including those presenting to the emergency department (ED) with chest pain. In his recent editorial, Scott1 expresses concerns that CCTA is a 'new test with possible unchartered hazards', and implies that the use of CCTA in evaluating acute chest pain is a premature application of this technology.
