Migraine and venous thrombosis: Another important piece of the puzzle

摘要

In this issue of Research and Practice in Thrombosis and Haemostasis(RPTH), Folsom and colleagues report on the association betweena migraine history and the risk of venous thromboembolism (VTE)in older adults.1 For this purpose, the authors carried out an analysison the well‐known cohort study “The Atherosclerosis Risk inCommunities (ARIC) Cohort,” in which patients were interviewedfrom 1993 through 1995 regarding migraine, and followed for subsequentVTE through 2013. The analytic population comprisednearly 12 000 individuals, and the authors concluded that a migrainehistory was not associated with an increased risk of VTE (adjustedhazard ratio, 1.06; 95% confidence interval [CI], 0.82‐1.36). While noassociation was observed between migraine without aura and VTE(adjusted hazard ratio, 0.97; 95% CI, 0.71‐1.32), a weak associationbetween migraine with aura and VTE could not be entirely ruled out(adjusted hazard ratio, 1.25; 95% CI, 0.85‐1.85).
