A-011 High Sensitive Troponin Assays for Differentiating the Patients with Unstable Angina from Stable Angina

Abstract Background There have been no cardiac biomarkers used in the diagnosis of unstable angina. In this study, we examined high sensitive troponin T and I as a marker to differentiate patients with angina from stable Methods A total 816 (59 AMI, 94 angina, 99 623 healthy individuals) were included. All had glomerular filtration rate ≥60 mL/min/1.73 m2. Leftover serum samples obtained who visited The Catholic University Korea, St Vincent’s Hospital April November, 2019. Cardiac was measured using Beckman Coulter Access sensitivity cTnI assay, Abbott Architect TnI Roche Elecsys Troponin T-high assay. Results 99th percentile URLs (Upper Reference Limits) cTnI, cTnT are 9.8 ng/L, 17.9 16.4 respectively. 9.1% (9/99), 5.1% (5/99), 6.1% (6/99) showed higher values than each URL cTnT, 24.5% (23/94), 25.5% (24/94) significant differences between frequencies showing troponins URL. Conclusion High could be useful for differentiation
