Migraine has complex relationships with cerebrovascular and cardiovascular disorders but also with cardiac anomalies. Patients affected by migraine with aura have an increased prevalence of right-to-left shunt due to patent foramen ovale or pulmonary arteriovenous malformations. The association between ischemic heart disease, cardiovascular mortality and migraine remains unsettled. The debate focuses on a physiopathological link between migraine and cardiovascular diseases or a higher prevalence of risk factors in migraineurs.
