BackgroundWe studied the usefulness of hemostatic biomarkers in assessing the pathology of thrombus formation, subtype diagnosis, prognosis in the acute phase of cerebral infarction, and differences between various hemostatic biomarkers.MethodsOur study included 69 patients with acute cerebral infarction who had been hospitalized within 2 days of stroke onset. Fibrin monomer complex (FMC), soluble fibrin (SF), D-dimer, thrombin-antithrombin III complex, fibrinogen, antithrombin III, and fibrin/fibrinogen degradation products (FDPs) were assayed as hemostatic biomarkers on days 1, 2, 3, and 7 of hospitalization.ResultsIn the cardioembolic (CE) stroke group, FMC and SF levels were significantly higher on days 1 and 2 of hospitalization, and D-dimer levels were significantly higher on day 1 of hospitalization, compared to the noncardioembolic (non-CE) stroke group. FDP levels were significantly higher at all times in the CE group compared to the non-CE group. Neither the National Institute of Health Stroke Scale (NIHSS) used during hospitalization nor the modified Rankin Scale (mRS) used at discharge found any significant correlations to hemostatic biomarkers, but the NIHSS score during hospitalization was significantly higher in the CE group than in the non-CE group.ConclusionsMeasurements of hemostatic biomarkers, such as FMC, SF, and D-dimer on the early stage of cerebral infarction are useful for distinguishing between CE and non-CE stroke.Copyright © 2012 National Stroke Association.
