AbstractBackground: Migraine prevalence has been estimated to be as high as 25% during reproductive years. Despite this, and the known significantly lower odds of acute stroke being correctly diagnosed among women versus men, little is known about the migraine-stroke connection in this vulnerable population. Our study seeks to provide a consolidated examination of cerebrovascular and obstetric complications of migraines in pregnant women and to evaluate the role of concurrent comorbidities. Methods: We utilized the 2016-2020 Healthcare Cost and Utilization Project's National Inpatient Sample with the International Classification of Diseases, 10th Revision diagnostic codes to compare pregnant patients with migraines with those without migraines. Multivariable logistic regression was used to examine the incidence of subtypes of stroke while controlling for confounding variables. Results: Overall, 19,825,525 pregnant patients were evaluated; 219,175 (1.1%) had a concomitant diagnosis of migraine. Pregnant patients with migraines were more likely to suffer ischemic (0.1% versus 0.0%) or hemorrhagic stroke (0.3% versus 0.1%). On multivariate analysis, acute ischemic stroke was most strongly associated with migraine with aura (odds ratio [OR], 23.26; 95% confidence interval [CI], 18.46-29.31), followed by migraine without aura (OR, 8.15; 95% CI, 4.79-13.88). Conclusions: Pregnant women with migraine are at a significantly increased risk for both ischemic and hemorrhagic stroke. Pregnant women with migraines should be cautioned that they may be at an increased risk of stroke, particularly if they are experiencing an aura, and encouraged to contact their medical providers to rule out neurological complications.
