TNNT2 and myocardial infarction: These findings are supported by a subanalysis of the TRAPID-AMI (The High Sensitivity Cardiac Troponin T Assay for Rapid Rule-out of Acute Myocardial Infarction) study, which enrolled over 1200 patients (37% women) with chest pain to assess whether the application of Saenger's sex-oriented cut-offs for hs-cTnT would lead to a better reclassification of MI and an improvement in prognosis.
