RESUMEN
BACKGROUND & PURPOSE: Fibrinoeptide-A (FpA) and D-dimer have been well known as hematologic parameters for activation of the coagulation and the endogeneous fibrinolysis system during acute phase of ischemic stroke. We measured the levels of FpA and D-dimer in acute progressive and non-progressive ischemic strokes to assess whether these markers are valuable as a predictor of stroke progression during acute phase. METHODS: FpA (RIA method) and D dimer (ELISA method) were determined in 54 patients, 9 with acute progressive and 45 with non-progressive within acute stage(< 48 hours of onset) of cerebral infarction. RESULTS: Levels of FpA in patients with acute progressive stroke were significantly higher than those in patients with non-progressive stroke, indicating activation of the coagulation system (P = 0.013). And, levels of D-dimer in patients with acute progressive stroke were also higher than those in patients with non-progressive stroke but statistically insignificant(P-0.071). CONCLUSIONS: These findings suggest that the coagulation system is more enhanced in progressive stroke than non-progressive one during acute stage of ischemic stroke. Higher levels of FpA are thought to be useful markers to predict stroke in progression.
