Cardiac troponin and defining myocardial infarction

  Figure 1. Schematic of the 4th Universal Definition of Myocardial Infarction (UDMI). The blood sample is from a patient with suspected non-ST elevation acute coronary syndrome. The sieve represents the cardiac troponin concentration cut-point at the 99th centile upper reference limit. In patients with troponin above this concentration, the UDMI recommends a differentiation of myocardial infarction from injury, and emphasizes the use of the best imaging techniques available to define aetiology of myocardial injury (preferably cardiac magnetic resonance imaging).1 See text for further details.
