Multicenter Study Comparative StudyHigh-sensitivity cardiac troponin T for earlier diagnosis of acute myocardial infarction in patients with initially negative troponin T test--comparison between cardiac markers.
An early diagnosis is essential for therapeutic decision and risk stratification in patients with suspected acute myocardial infarction (AMI). We analyzed and compared the diagnostic value of high-sensitivity troponin T (hs-TnT) and other cardiac markers in patients with an initially negative troponin T test at presentation. ⋯ The hs-TnT displayed 100% sensitivity and negative predictive value for the patients admitted more than 120 min from the onset, however the specificity was limited. The absolute change from T0 to T3 (22 ng/L) improved the total diagnostic performance.
