Troponin is a widely used biomarker in patients with cardiac disease. In this Review, Westermann et al. describe the development of high-sensitivity assays for troponin, and their practical use in clinical diagnosis of acute myocardial infarction. Elevated concentrations of troponin in myocardial injury and chronic cardiac disease are also discussed.
