Study Details

Study Description

Brief Summary

BACKGROUND: We sought to determine the diagnostic value of the new TnThs assay for early detection of evolving non-STEMI in patients with acute coronary syndrome and a negative 4th generation cTnT result on admission.

METHODS: We evaluated several statistical patterns of blood results of TnT hs and cTnT of 115 patients and calculated necessity of prediction of evolving non-STEMI within 6 hours.

RESULTS: Based on the results of the 4th generation cTnT assay, an evolving non-STEMI was diagnosed in 26 patients, 31 were classified as unstable angina. The TnThs lead to an increase of non-STEMI diagnosis as compared to the 4th generation assay. We could calculate increased sensitivities for earlier detection of evolving non-STEMI from 61.5% on admission to 90.9% within 3 hours and 100% within 6 hours compared to cTnT.

CONCLUSIONS: The TnThs assay enables earlier detection of non-STEMI and allows identification of an additional percentage of cases with non-STEMI previously classified as unstable angina.
