WebJun 10, 2011 · The objective of this study was to compare the diagnostic performance of a new high-sensitivity troponin T (HsTnT) assay to that of conventional cTnI for the diagnosis of acute myocardial infarction (AMI) according to pretest probability (PTP). Methods WebResults. There was tremendous variability in the studies making the results unclear. Regarding diagnostic accuracy they found: The sensitivity for ACS diagnosis ranged from 71% to 100% for troponin T and from 43% to 94% for troponin I.
