Abstract
Emergency physicians are tasked with risk stratifying patients presenting with suspected acute coronary syndromes (SACS). In the era of contemporary troponin (Tn) assays, patients with a Tn above the upper reference level (URL; 99th percentile of a healthy population) were commonly admitted, with the remaining risk-stratified by the application of their published scoring systems (eg, TIMI, EDACS, HEART) into discharge or not (observe or admit) cohorts. With the availability of high-sensitivity Tn (hsTn), the contribution of scoring systems to the risk stratification of patients with low hsTn levels is uncertain.
