RESUMO
In stroke patients higher levels of plasma fibrinogen are associated with increased risk of unfavourable functional outcome and short-term mortality. The aim of our study was to determine the relationship between plasma fibrinogen level and long-term risk of death in ischemic stroke patients. Seven hundred thirty six patients (median age 71; 47.1% men) admitted to the stroke unit within 24 h after stroke were included. Plasma fibrinogen level was measured on day 1 of hospitalisation. Hyperfibrinogenemia was defined as plasma fibrinogen concentration >3.5 g/L. The maximal follow-up period was 84 months. Hyperfibrinogenemia was found in 25.0% of patients. On multivariate logistic regression analysis, after adjustment for age, stroke severity, atrial fibrillation, smoking, white blood cell count, fever, in-hospital pneumonia and hyperglycemia, hyperfibrinogenemia was associated with increased case fatality (HR 1.71, 95% CI 1.29-2.26, P < 0.01). Hyperfibrinogenemia predicts the long-term risk of death in ischemic stroke patients.
