Markers of activated coagulation for early diagnosis of acute myocardial infarction.

Intracoronary thrombosis plays a key role in the pathogenesis of acute myocardial infarction (AMI), and the formation of an occlusive thrombus usually precedes the development of myocardial damage. Therefore we evaluated and compared the early sensitivities of thrombin-antithrombin III complex (TAT), D-dimer, myoglobin, creatine kinase (CK) MB mass concentration, and cardiac troponin T (cTnT) on admission to a coronary care unit (CCU) before heparin or thrombolytic therapy was started. We investigated 31 consecutive patients admitted to CCU for evolving AMI within 6 hours from the onset of infarct-related symptoms; the median delay from chest pain onset to CCU admission was 135 minutes. Of all biochemical markers tested TAT had the highest early sensitivity on admission to the CCU, and TAT was significantly more sensitive than cTnT, CKMB mass, myoglobin, and D-dimer. However, TAT increases give no information about the location of clot formation in the body, and the diagnosis of AMI must be subsequently verified by an increase in more cardiac specific proteins, such as troponins or CKMB.[1]
