Key clinical point: Presence of migraine poses a strong risk for incident venous thromboembolism (VTE), whereas VTE is modest risk factor for the onset of migraine.
Major finding: The risk of developing VTE was significantly higher in patients with vs without migraine (odds ratio [OR] 96.155; P = .004). Conversely, the risk for migraine was modestly higher in patients with vs without VTE (OR 1.002; P = .016).
Study details: This two-sample bidirectional Mendelian randomization study evaluated the causal association between migraine and VTE using single-nucleotide polymorphisms as instrumental variables obtained from large-scale Genome-Wide Association Studies public databases (IEU Open GWAS project, FinnGen).
Disclosures: The study did not disclose any funding. The authors declared no conflicts of interest.
