title: An overview of biochemical markers in acute coronary syndromes.
abstract: The cardiac troponins (cTns), cTnT and cTnI, are currently regarded as being the most useful diagnostic and prognostic biochemical markers of myocardial damage in patients with suspected acute coronary syndromes (ACSs). In spite of the evidence-based nature of this observation, the uptake of serum cTn measurement in routine clinical practice--in both the UK and elsewhere, is patchy, indeed, there still exists wide variability in the range of testing and sampling strategies involving usage of the many existing cardiac markers. For evaluating suspected acute myocardial infarction (AMI) and other ACSs, international opinion favours either serum cTnT or cTnI (measured 12-24 h after admission to the emergency room)--together with a short-time window marker such as serum creatine kinase (CK) (measured on admission and perhaps again within the 12-24 h window). Translation of this strategy into universal clinical practice would require not only formulation of, but also strict adherence to, agreed clinical decision-making protocols which, in turn, would need to be backed by adequate funding.
