Mitral valve prolapse and platelet aggregation in patients with hemiplegic and non-hemiplegic migraine
Abstract:
Migraine and mitral valve prolapse (MVP) share a number of features. Both migraine and MVP show platelet dysfunctions and an increased risk of transient ischemic attacks (TIA) and stroke. There is a strikingly high incidence of migraine among MVP patients. The focal neurological deficits associated with hemiplegic migraine resemble TIA symptoms which may occur in MVP patients. Furthermore, the risk of cerebral infarction in migraineurs is reported to be higher than in the general population. The results of our study with 43 patients suffering from non-hemiplegic migraine (common and classical migraine) and 19 migraineurs with a hemiplegic migraine indicate that hemiplegic migraine is not associated with MVP and increased platelet aggregation more frequently than other migraine forms. Independent of migraine type, there is no difference between patients with and without mitral valve prolapse with respect to platelet dysfunction.
Insights
Migraine and mitral valve prolapse (MVP) share similarities, but this study found no increased platelet dysfunction in hemiplegic migraine patients with MVP. Findings suggest MVP is not more frequent in hemiplegic migraineurs.
Area of Science:
- Neurology
- Cardiology
- Hematology
Background:
- Migraine and mitral valve prolapse (MVP) share features like platelet dysfunction and increased risk of stroke.
- A high incidence of migraine is observed in MVP patients, with neurological deficits mimicking transient ischemic attacks (TIA).
- Cerebral infarction risk is elevated in migraineurs.
Purpose of the Study:
- To investigate the association between hemiplegic migraine and mitral valve prolapse (MVP).
- To compare platelet aggregation and dysfunction in migraineurs with and without MVP.
- To determine if hemiplegic migraine is linked to MVP and increased platelet aggregation more than other migraine types.
Main Methods:
- Study included 43 patients with non-hemiplegic migraine and 19 with hemiplegic migraine.
- Assessed platelet dysfunction and aggregation.
- Compared findings between migraineurs with and without MVP, independent of migraine type.
Main Results:
- Hemiplegic migraine was not found to be more frequently associated with MVP and increased platelet aggregation compared to other migraine forms.
- No significant difference in platelet dysfunction was observed between patients with and without MVP, irrespective of migraine type.
Conclusions:
- The study suggests that hemiplegic migraine is not specifically associated with mitral valve prolapse or heightened platelet aggregation.
- Platelet function appears similar in migraine patients with and without MVP, regardless of migraine subtype.
