Aortic stiffness and pulse wave reflection in young subjects with migraine: A case-control study

Area of Science:

• Cardiology
• Neurology
• Vascular Medicine

Background:

• Migraine is associated with increased risk of ischemic stroke and cardiovascular events.
• The underlying mechanisms linking migraine to cardiovascular disease remain unclear.
• Aortic stiffness, measured by pulse wave velocity (PWV), is a predictor of cardiovascular disease.

Purpose of the Study:

• To investigate if aortic stiffness is increased in young migraineurs without overt cardiovascular disease or major risk factors.
• To explore aortic pulse wave velocity (PWV) as a potential link between migraine and cardiovascular risk.

Main Methods:

• A study involving 60 migraine patients and 60 matched healthy controls.
• Carotid-femoral PWV and aortic augmentation index measured using applanation tonometry.
• Exclusion of participants with overt cardiovascular disease, diabetes, or major cardiovascular risk factors.

Main Results:

• Migraine patients exhibited significantly higher aortic PWV and aortic augmentation compared to controls.
• Migraine with aura was associated with even higher aortic PWV than migraine without aura.
• Age, mean arterial pressure, and migraine independently predicted aortic PWV.

Conclusions:

• Migraine is independently associated with increased aortic stiffness and enhanced pressure wave reflection.
• This increased aortic stiffness in young migraineurs without major risk factors may explain their heightened cardiovascular risk.
• Aortic stiffness could be a key mechanism linking migraine to cardiovascular disease.
