Effect of Exercise Treadmill Testing and Stress Imaging on the Triage of Patients With Chest Pain: CHEER Substudy

Exercise treadmill testing safely stratified most intermediate-risk patients with unstable angina and was less costly than routine admission. Patients not suitable for ETT are likely to have abnormal stress imaging results. They represent a higher-risk cohort that could be routinely admitted to the hospital without reducing the effectiveness of the CPU strategy.
