Acta Neurol Scand: 2011: 124: 40–44. © 2010 John Wiley & Sons A/S. Background – Patients with acute ischemic stroke and atrial fibrillation are at increased risk of stroke progression and recurrence. We sought to assess whether D-dimer and other markers of hemostatic activation could predict these adverse events in such patients. Method – Blood samples were obtained from patients included in the Heparin in Acute Embolic Stroke Trial. Stroke progression was defined as a ≥3-point worsening on the Scandinavian Stroke Scale during the first 48 h after randomization. Blood samples were analyzed for D-dimer, prothrombin fragment 1 + 2, soluble fibrin monomer, and C-reactive protein. Results – A total of 382 patients were included in the analyses. Levels of D-dimer and other markers of hemostatic activation were not significantly higher in patients with stroke progression than in other patients (D-dimer median values: 1025 ng/ml vs 970 ng/ml, P = 0.73). The same was true for recurrent stroke (D-dimer: 720 ng/ml vs 973 ng/ml, P = 0.96), and the combined endpoint of stroke progression, recurrent stroke, and death (D-dimer: 991 ng/ml vs 970 ng/ml, P = 0.91). Multivariable analyses did not alter the results. Conclusion – D-dimer and other markers of hemostatic activation were not associated with stroke progression, recurrent stroke, or death in patients with acute ischemic stroke and atrial fibrillation. |
