BACKGROUND AND PURPOSE: Migraine is reportedly associated with several cardio-cerebrovascular diseases (CCDs), but some of these diseases have not received sufficient attention. We thus attempted to determine the associations of migraine with peripheral arterial disease (PAD), ischemic heart disease (IHD), atrial fibrillation/flutter (AF), ischemic stroke (IS), and hemorrhagic stroke (HS).

METHODS: The study population was recruited by applying International Classification of Diseases, Tenth Revision (ICD-10) codes to the database of the Korean National Health Insurance Service from 2002 to 2018. Cumulative incidence curves were plotted to compare the incidence rates of CCDs between the migraine (ICD-10 code G43; n=130,050) and nonmigraine (n=130,050) groups determined using 1:1 propensity-score matching. Cox proportional-hazards regression models were used to obtain adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for CCDs in patients with any migraine, migraine with aura (n=99,751), and migraine without aura (n=19,562) compared with nonmigraine controls.

RESULTS: For all CCDs, the cumulative incidence rates were higher in the migraine group than the nonmigraine group (p<0.001 in log-rank test). Any migraine, irrespective of the presence of aura, was associated with PAD (aHR 2.29, 95% CI 2.06-2.53), IHD (aHR 2.17, 95% CI 2.12-2.23), AF (aHR 1.84, 95% CI 1.70-1.99), IS (aHR 2.91, 95% CI 2.67-3.16), and HS (aHR 2.46, 95% CI 2.23-2.71). aHR was higher in female than in male migraineurs for all of the CCDs.

CONCLUSIONS: Associations of migraine with CCDs have been demonstrated, which are stronger in females than in males.
