This article states that although men who suffer from migraines are more likely to experience heart attacks, scientists have failed to find a biological mechanism linking them. Such a link seems to be suggested in an earlier Science News article, “A Gasping Heart” (SN: 4/7/07, p. 218), which states that a patent foramen ovale is linked to migraines and that that heart defect, combined with sleep apnea, can cause oxygen desaturation, which can be a factor in cardiovascular disease.
