Migraine and biomarkers of cardiovascular disease in women.

Migraine has been associated with an unfavourable cardiovascular risk profile and with increased risk of cardiovascular disease. In a cross-sectional analysis of 27,626 women aged >or=45 years, we evaluated the association of migraine and migraine aura status with elevated levels of total cholesterol, low- and high-density lipoprotein cholesterol (HDL-C), non-HDL-C, apolipoprotein (Apo) A-1 and B(100), lipoprotein (a), C-reactive protein (CRP), fibrinogen, intercellular adhesion molecule-1, homocysteine and creatinine. A total of 5087 (18.4%) women reported any history of migraine. Compared with women with no migraine history, women who reported any history of migraine had modestly increased adjusted odds ratios (95% confidence interval) of 1.09 (1.01, 1.18) for elevated total cholesterol, 1.14 (1.05, 1.23) for non-HDL-C, 1.09 (1.01, 1.18) for Apo B(100) and 1.13 (1.05, 1.22) for CRP. The increase did not meaningfully differ according to migraine aura status and migraine frequency. In this large cohort of women, only a modest association was found between migraine and adverse levels of certain cardiovascular biomarkers.
