Post-Thrombolytic D-Dimer Elevation Predicts Symptomatic Intracranial Hemorrhage and Poor Functional Outcome After Intravenous Thrombolysis in Acute Ischemic Stroke Patients
Abstract
Background: We aimed to investigate the association of post-thrombolytic D-dimer elevation with symptomatic intracranial hemorrhage (sICH) and functional outcome in AIS patients receiving intravenous thrombolysis.
Methods: We retrospectively reviewed our database for patients with AIS who received intravenous thrombolysis between August 2018 and December 2021. ΔD-dimer was calculated as follow-up D-dimer minus baseline D-dimer. Poor functional outcome was defined as 3 months modified Rankin score (mRS) 3-6. sICH was defined as cerebral hemorrhagic transformation in combination with clinical deterioration of National Institutes of Health Stroke Scale (NIHSS) score ≥4 points at 24 hours. Binary logistic regression analysis was used to investigate the association of post-thrombolytic D-dimer parameters with sICH and poor functional outcome. The receiver operating characteristic (ROC) curve derived optimal cut-off of different D-dimer parameters was determined at the maximal Youden's Index.
Results: A total of 325 patients were finally included. After controlling for clinical variables, follow-up D-dimer level (OR 1.230; 95% CI 1.119 to 1.351; P < 0.001) and ΔD-dimer (OR 1.347; 95% CI 1.165 to 1.559; P < 0.001) were independently associated with poor functional outcome. Additionally, follow-up D-dimer level (OR 1.095; 95% CI 1.009 to 1.188; P = 0.030) was independently related to sICH. The optimal cut-off value of follow-up D-dimer level for predicting sICH was 4185 μg/L (area under the curve 0.760; sensitivity 76.0%; specificity 81.3%); and the optimal cut-off value of follow-up D-dimer level and ΔD-dimer as a predictor for poor functional outcome was projected to be 3838 μg/L and 2190 μg/L, which yielded a sensitivity and a specificity of 62.3%, 84.5% and 73.8%, 85.2%, respectively.
Conclusion: Elevated follow-up D-dimer levels are associated with sICH and poor functional outcome in AIS patients following intravenous rt-PA. Moreover, post-thrombolytic D-dimer elevation, measured by ΔD-dimer, was a better predictive biomarker for long-term outcome at 3 months.
