Migraine has already been identified as a risk factor for ischemic stroke. A recent study looks more at this connection, suggesting surgery patients with migraine are at an increased risk of stroke around the time of a surgical procedure.
“Migraine should be incorporated in the assessment for risk of perioperative (time period spanning the duration of a patient’s surgery, including preoperative and postoperative) stroke,” Matthias Eikermann, MD, PhD, one author of the study, told Medscape Medical News.
Researchers reviewed data on patients who had surgery at Massachusetts General Hospital and two affiliated community hospitals between January 2007 and August 2014. Of those patients, 8.2% of patients had been diagnosed with migraine.
“In this large cohort of surgical patients, migraine was associated with an increased risk of perioperative ischemic stroke within 30 days of surgery,” the authors of the study concluded. The study was published online in the British Medical Journal.
The authors said this study adds to evidence that migraine, specifically migraine with aura, is a marker for increased risk of stroke.
“We content that this association has clinical relevance in a growing list of risk factors that should be considered to promote disability-free survival,” the authors of the study said.
