Popis: Background: D-dimer has been evaluated as an independent marker of ischemic stroke. The non-existence of a clear consensus and pooled data about the use of D-dimer as a predictive biomarker for assessing the risk of stroke recurrence led us to perform this systematic review and meta-analysis. Methods: Studies reporting the risk of stroke recurrence with varying degrees of high D-dimer levels were screened through August 2021 using PubMed/Medline, Scopus, EMBASE and Web of Science databases and relevant keywords. Random effects models by Dersimonian & Laird were used for meta-analysis and subgroup analysis. I 2 statistics were used for heterogeneity assessment. The leave-one-out method was used for sensitivity analysis. Results: This systematic review included 5040 patients from 9 studies consisting of >60% males. There was a high burden of cardiovascular comorbidities, smoking and diabetes in stroke patients with or without associated diagnoses and high D-dimer levels. Compared to low D-dimer levels, higher plasma D-dimer levels were associated with ~80% (aOR 1.79, 95% CI: 1.24-2.59) increased risk of stroke recurrence. The odds of stroke recurrence were significantly high in the stroke cohorts including patients with mean age (Fig. 1) . In addition, elevated D-dimer levels showed a robust association for stroke recurrence in studies with higher sample size (n>500 vs. n Conclusion: This meta-analysis showed that high D-dimer levels were associated with nearly 80% higher odds of stroke recurrence irrespective of the etiology of index stroke events. Stronger associations were seen in studies with a mean age
