title: Copeptin as a biomarker in cardiac disease.
abstract: The introduction of biochemical biomarkers in the evaluation of patients with cardiovascular disease has led to practice-changing advancements in the way these patients are diagnosed and managed. Measurements of cardiac troponins or brain-type natriuretic peptide (BNP) and its precursor, N-terminal brain-type natriuretic peptide (NT-proBNP), have become indispensable in the evaluation of patients with acute coronary syndromes and heart failure, respectively, constituting an integral part of the diagnostic algorithm and risk stratification of these conditions. Copeptin, a glycopeptide, part of the prehormone molecule of the antidiuretic hormone - or arginine-vasopressin - has shown considerable promise in this field. There is evidence that copeptin might be useful as a diagnostic or prognostic biomarker and risk-stratifier in a range of cardiovascular disease conditions. The main clinical scenarios where copeptin has been studied as a biomarker are: early rule-out of myocardial infarction in patients with acute chest pain, diagnosis of heart failure in patients with acute dyspnea and determining the prognosis of destabilized or chronic stable heart failure. The present review is aimed at providing concise information about the molecular structure and biosynthesis of copeptin, the available medical chemistry methods of quantification, and the potential clinical uses of this molecule in patients with heart disease.
