Lear A, et al. - The authors aimed at determining if admission, and provocative stress testing of patients who have ruled out for acute coronary syndrome put patients with low-risk category for coronary artery disease (CAD) at risk for false-positive provocative stress testing and unnecessary coronary angiogram/imaging. Among all patients admitted/observed after Emergency Department presentation with chest pain, follow-up provocative testing was unlikely to find CAD in patients with low pretest probability. They noted that testing all low-probability patients puts them at increased risk for unnecessary invasive confirmatory testing.
