However, at a population level, this risk deserves attention because the prevalence of migraine is so high. The absolute risk of stroke for most migraine patients is low, so a doubling of risk is not cause for panic, explains Elizabeth Loder from Brigham and Women's Hospital, Boston, in an accompanying editorial. ![]() They also call for additional research to investigate the association between migraine and cardiovascular disease in more detail. In light of these findings, the authors recommend that young women who have migraine with aura should be strongly advised to stop smoking, and methods of birth control other than estrogen containing contraceptives should be considered. There was no association between migraine and heart attack or death due to cardiovascular disease. This risk is further increased by being female, age less than 45 years, smoking, and estrogen containing contraceptive use. They show that migraine with aura is associated with a twofold increased risk of ischemic stroke. Differences in study design and quality were taken into account to minimise bias. So to investigate this further, an international team of researchers analysed the results of nine studies on the association between any migraine (with and without aura) and cardiovascular disease. Up to one third of sufferers also experience an aura prior to or during a migraine headache (often described as the perception of a strange light, an unpleasant smell or confusing thoughts or experiences).ĭoctors have long suspected a connection between migraine and vascular events such as stroke. Women are affected up to four times more often than men. Migraine is a common, chronic disorder that affects up to 20% of the population. In addition, researchers examined how often surgical patients were admitted to the hospital within 30 days of being sent home.The risk was highest among young women with migraine with aura who smoke and use estrogen containing contraceptives. For patients with a history of migraine, the risk increased to about 4.3 strokes for every 1,000 surgical patients. The absolute risk of stroke was about 2.4 cases for every 1,000 surgical patients, researchers estimated. Most often, strokes occurred after vascular, heart or brain surgery.Īmong all the patients who had a stroke, 89 of them, or about 12 percent, had a history of migraine with or without aura. Overall, 771 people had a stroke within 30 days of surgery, or less than 1 percent of the study population. Of these 8,901 patients diagnosed with migraine, 1,278 had migraine with aura. People with a history of migraines made up about 8 percent of the total cases. To assess how migraine history influenced the odds of stroke following surgery, researchers examined data on 124,588 patients who had operations requiring general anesthesia and mechanical ventilation from 2007 to 2014. Up to one in five people get migraines, a chronic, often debilitating disorder characterized by severe headaches as well as symptoms like nausea and intense sensitivity to sight or sound, researchers note in The BMJ. Many previous studies have linked migraine to an increased risk of stroke. Ischemic stroke, the most common type, results from an obstruction in a blood vessel supplying the brain. Matthias Eikermann of Harvard University and Massachusetts General Hospital in Boston. ![]() “Our study shows that patients with migraine, particularly migraine with aura, undergoing a surgical procedure are at increased risk of perioperative ischemic stroke and readmission to hospital within 30 days after discharge,” said senior study author Dr. When patients had a history of migraines with aura – or visual symptoms such as flashing or shimmering lights, zigzagging lines or stars – the odds of stroke were more than doubled. ![]() While stroke was rare in the study, the odds of stroke within 30 days of surgery were 75 percent higher for people with a history of migraines. (Reuters Health) - People with a history of migraines may be more likely to have a stroke after surgery than patients who don’t get these severe headaches, a recent study suggests.
