Multicenter Study Clinical Trial
Incremental value of high-sensitivity cardiac troponin T for risk prediction in patients with suspected acute myocardial infarction.
High-sensitivity cardiac troponin assays have better analytical precision and sensitivity than earlier-generation assays when measuring cardiac troponin at low concentrations. We evaluated whether use of a high-sensitivity assay could further improve risk stratification compared with a standard cardiac troponin assay. ⋯ Concentrations of hs-cTnT >0.014 μg/L improve the prediction of death but not subsequent AMI in unselected patients presenting with acute chest pain.
