Thrombogenesis in myocardial infarction and related syndromes: the role of molecular markers in diagnosis and management.
Anticoagulant therapy has undergone some major developments in recent years. Conventional drugs that produce anticoagulant effects such as heparin and oral anticoagulants are no longer considered the only candidates for the anticoagulant/antithrombotic management of patients. Recombinant hirudin, glycoproteins IIb/IIIa targeting antibodies, synthetic peptides such as Hirulog and efegatran are being tested for their efficacy. These drugs produce their effects at different sites. To monitor their overall effects on the hemostatic system, molecular markers offer a practical and reliable approach. Markers of thrombin generation are useful for the monitoring of antithrombin drugs whereas, the efficacy of antiplatelet drugs can be assessed by monitoring the platelet release products. Furthermore, polytherapy using several anticoagulant and antithrombotic drugs in combination has been considered. In these situations, the use of molecular markers may also prove to be invaluable. The introduction of simple technology such as the test strip or particle agglutination methods may be available for the measurement of many of these markers in the near future. This will be useful for ready availability and reduced cost for individual marker testing. Furthermore, this type of technology can be used at bedside, off-site, and in doctor's offices. It is clear that the molecular marker profiling provides useful information on the nature of pathophysiology of a given thrombotic disorder. However, for practical use, a cost-effective and simpler assay-based approach will enhance their use, and these tests will be readily accepted at the laboratory and clinical levels.
