Abstract:
In the second part of the paper, we discuss the relationship between migraine with aura and either patent foramen ovale (PFO) or stroke. The results of the studies suggest that PFO with right-to-left shunt is more prevalent among patients suffering from migraine with aura. Moreover, migraine with aura is a risk factor for ischaemic stroke in women and the risk increases when they have additional vascular risk factors such as taking oral contraception and smoking. However, the pathophysiology of these phenomena remains hypothetical. The most frequently reported theory suggests paradoxical embolism as a mechanism of the above-mentioned pathologies. In this paper we compare the pros and cons of the general theories. We discuss the percutaneous closure of PFO in patients with migraine, regarding the benefit/risk ratio.
Insights
Patent foramen ovale (PFO) is more common in migraine with aura patients. Migraine with aura increases stroke risk in women, especially with other vascular factors.
Area of Science:
- Neurology
- Cardiology
- Vascular Medicine
Background:
- Migraine with aura (MWA) is a neurological condition.
- Patent foramen ovale (PFO) is a cardiac anomaly.
- The link between MWA, PFO, and stroke requires further elucidation.
Purpose of the Study:
- To explore the association between migraine with aura and patent foramen ovale (PFO).
- To evaluate migraine with aura as a risk factor for ischemic stroke.
- To discuss the pathophysiology and treatment implications, including PFO closure.
Main Methods:
- Review of existing studies on migraine with aura, PFO, and stroke.
- Analysis of prevalence data for PFO in MWA patients.
- Discussion of theoretical mechanisms, including paradoxical embolism.
Main Results:
- PFO with right-to-left shunt is more prevalent in patients with migraine with aura.
- Migraine with aura is identified as a risk factor for ischemic stroke in women.
- The risk of stroke is amplified by coexisting vascular risk factors like oral contraceptive use and smoking.
Conclusions:
- The association between MWA and PFO is significant, with paradoxical embolism as a leading hypothesis.
- Migraine with aura poses a notable risk for ischemic stroke in women, particularly when combined with other vascular risk factors.
- The benefit-risk ratio of percutaneous PFO closure in migraine patients warrants careful consideration.
