Abstract
BackgroundThe aim of our study was to evaluate the risk for comorbid cardio- and cerebrovascular diseases in the working-aged migraine population of Finland.MethodsA total of 1505 cases who reported diagnosed migraine and 3010 controls from a cohort of 11,596 cases in the Finnish Health and Social Support Study were included. The study material was linked with two registers. ICD diagnoses I63 for ischemic stroke (IS), I21 − I22 for acute myocardial infarction (AMI), and G43 for transient ischemic attack (TIA) among study participants were drawn from the national Finnish Care Register for Health Care at the follow-up in 2012. Reimbursed triptan prescriptions were drawn from the national Social Security Institution (SII) data. The self-reported vascular risk factors were hypertension, high cholesterol values, any diabetes, myocardial infarction, stroke, and TIA. Odds Ratios (OR) with 95% confidence (95% CI) intervals were assessed for diagnosed stroke, myocardial infarction, and TIA.ResultsMigraineurs were mostly female (82%) and ≥ 54 years old (62%). Triptans were reimbursed among 34.7% of migraineurs. A self-reported hypertension (21%), high serum cholesterol (38%), and any diabetes (7%) were more common among migraineurs vs controls (p < 0.05). There was no risk for AMI. The risk for TIA (OR 3.20, 95% CI 1.45–7.05) and IS (2.57, 95% CI 1.28–5.17) among migraineurs vs controls remained high after adjustment for self-reported hypertension, obesity, and smoking. The risk was higher among women in two groups ≥54 years (3.25, 95% CI 1.35–7.84 and 5.0, 95% CI 1.94–12.89, respectively). The average age for IS in migraine was 57.5 years and for TIA 58.2 years among women, and 52.8 years and 50.3 years among men, respectively.ConclusionCardiovascular risk should be screened in the aging migraine population, and hormonal and other migraine-related risk factors should be considered, especially among women. Efficacious attack treatment with triptans should be offered to migraine patients who do not show contraindications.

Triptans were reimbursed by the Security Institution (SII) in 522 cases (34.7%) among all migraineurs and in age groups up to 58 years, but less often (16%) in the oldest age group of 64–68 years (Table 1)
No difference was found for any diabetes, myocardial infarction, or angina pectoris (Table 2)
Summary
The aim of our study was to evaluate the risk for comorbid cardio- and cerebrovascular diseases in the working-aged migraine population of Finland. Migraine affects up to 15% of adults and peaks among women and the working-age population [1]. Population-based and prospective studies have consistently reported an increased risk of ischemic stroke and cardiovascular disease in patients with overall migraine [3]. Sumelahti et al BMC Public Health (2021) 21:1088 cardiovascular diseases relates to higher cardiovascular risk factors in migraineurs than in people without migraine [7]. Genetic overlap exists between migraine, ischemic stroke [7], and coronary artery diseases [8], pointing to an overlap with large-artery and cardioembolic subtypes and MO [7]
