15 (HealthDay News) --
patients face a higher risk for developing a blood clot in their veins,
a team of Austrian and Italian researchers reports.
studies have suggested that the absolute risk for a resulting stroke
among migraine patients is actually quite low, but the current work
turns conventional wisdom on its head by suggesting that a migraine
diagnosis raises the risk for such potentially fatal clotting incidents
-- known as venous thrombosis or thromboembolism -- while having little
or no impact on the risk for developing any hardening or narrowing of
study refutes the widespread view that migraine [patients] are more
likely to have hardening and narrowing of the arteries, [known as]
atherosclerosis," noted study co-author Dr. Stefan Kiechl, from the
department of neurology at Innsbruck Medical University, in Austria.
"Alternatively, it suggests that migraine patients are more prone to
develop blood clots in their veins."
people that develop clots in [their] veins are also at an increased
risk to develop clots in the arteries supplying brain and heart, our
finding may in part explain the excessrisk
of stroke and heart attacks in migraine
patients," Kiechl added.
and his colleagues from Bruneck Hospital in Italy are publishing their
findings in the Sept. 16 issue of Neurology.
