Diagnostic performance of high-sensitivity cardiac troponin T (hs-cTnT) varies depending on presenting symptoms in patients with suspected acute coronary syndrome (ACS). ⋯ The diagnostic performance of hs-cTnT in patients with suspected ACS depends on the leading presenting symptom. Patients admitted with dyspnea represent a high-risk cohort in which the diagnosis of ACS is less frequent and with inferior performance of serial hs-cTnT measurements. Higher hs-cTnT cutoffs at baseline and absolute changes after 6 h help to identify non-STEMI (ST segment elevation myocardial infarction) in this population.
