M. Dahm et al., VALUE OF MOLECULAR MARKERS IN THE INITIAL PHASE OF ORAL ANTICOAGULATION THERAPY AFTER HEART-VALVE REPLACEMENT WITH MECHANICAL PROSTHESES, Zeitschrift fur Kardiologie, 87, 1998, pp. 42-45
In a prospective study, 39 patients following aortic or mitral valve r
eplacement underwent investigation of molecular markers (prothrombin f
ragment F1+2, Factor II) in the initial phase of oral anticoagulation
therapy (OAT). The results demonstrate that, despite INR being in the
depicted range, the levels of the molecular markers remained high, ind
icating an increased risk of thromboembolic events. This leads to the
conclusion that molecular markers are superior to INR in the monitorin
g of the early phase of OAT.
