Abstract

Background: High sensitivity cardiac troponin (hs-cTn) assays are able to quantitate low concentrations of cTn and provide an opportunity to rule out acute myocardialinfarction (MI) at an early stage following a patient's presentation to an emergency department. The objectives of the current study were to examine the performance of single hs-cTnI measurement strategy to rule out acute MI and predict 30-day safety outcomes at presentation in these patients. Methods: This was a prospective, observational study of patients (n = 2333). Acute MI occurred in 299 patients (12.8%). Patients presented to US emergencydepartments with suspected acute coronary syndrome. Cardiac troponin measurements were obtained using theinvestigational ADVIA Centaur XPT TNIH (hs-cTnI) Assay (Siemens Healthcare Diagnostics Inc.). Clinical data and hs-cTnI results were analyzed to determine: 1) clinical sensitivity and negative predictive value (NPV) for ruling outacute MI and 2) safety outcomes of acute MI and death at30 days, using the hs-cTnI limit of detection (LoD) 1.6 ng/L concentration. Results: In patients with a hs-cTnI
