HIGH SENSITIVE TROPONIN T RULES OUT MYOCARDIAL INFARCTION 2 HOURS FROM ADMISSION IN CHEST PAIN PATIENTS.

Abstract

Results: The median (25th-75th percentile) time from onset of chest pain was 5.3 (3.3-7.7) hours. One hundred and fourteen (49%) patients had a MI and another 10 (4%) had other reasons for myocardial damage. Hs-TnT had higher sensitivity than conventional Tn assays to detect MI (table) and myocardial damage. The AUC (95%CI) to detect myocardial damage was on admission 0.97 (0.95-0.99) for Hs-TnT, 0.95 (0.93-0.98) for standard TnT and 0.95 (0.91-0.98) for TnI Conclusions: Using decision-limits according to recommendations, Hs-TnT is more sensitive than conventional Tn assays for early detection of myocardial damage and is able to rule out MI 2 hours from admission.
