Reinhardt SW, et al. - Researchers contemplated the variations in outcomes with clinical evaluation and noninvasive testing (coronary computed tomographic angiography [CCTA] or stress testing) vs clinical evaluation alone, in patients with acute chest pain. A longer length of stay (LOS), more downstream testing, more radiation exposure, and greater cost without an improvement in clinical outcomes were yielded via negative biomarkers, and a nonischemic ECG result, noninvasive testing with CCTA or stress testing, in patients presenting to the Emergency Department (ED) with acute chest pain.
