Insights
Migraine is linked to cardiovascular risks like high blood pressure and left ventricular hypertrophy. These findings suggest a potential role for left ventricular hypertrophy in the connection between migraine and cardiovascular events.
Area of Science:
- Cardiology
- Neurology
- Epidemiology
Background:
- The relationship between cardiovascular risk factors and cardiovascular diseases in individuals with migraine is not fully understood.
- Existing research requires further investigation into the specific mechanisms linking migraine to cardiovascular health.
Purpose of the Study:
- To investigate the associations between migraine and various cardiovascular risk factors.
- To explore novel cardiovascular risk predictors in the context of migraine.
Main Methods:
- Utilized data from the Finnish Health 2000 Survey (BRIF8901), including 5737 adults aged 30+.
- Analyzed 488 participants reporting migraine using logistic regression.
- Included conventional cardiovascular risk factors, educational attainment, left ventricular hypertrophy, and hemoglobin A1c in the analysis.
Main Results:
- Migraine was associated with female sex (OR=3.75), lower age (B=0.99), lower high-density lipoprotein cholesterol (OR=1.23), higher diastolic blood pressure (OR=1.31), and left ventricular hypertrophy (OR=1.32).
- The likelihood of left ventricular hypertrophy increased with migraine frequency.
Conclusions:
- Left ventricular hypertrophy may mediate the link between migraine and cardiovascular events, potentially due to migraine-related hypertension and dyslipidemia.
- Further research is warranted to confirm these findings and elucidate the underlying mechanisms.
Background:
The influence of cardiovascular risk factors on the probability of cardiovascular diseases in migraineurs is still being discussed.
Aims Of The Study:
To further elucidate the mechanisms of these relationships, we assessed the associations between migraine and cardiovascular risk factors, including those that have been recently shown to improve the prediction of cardiovascular events.
Methods:
We used the data of the Finnish Health 2000 Survey (BRIF8901), consisting of 5737 subjects aged 30 years or older. In total, 488 participants reported migraine. In addition to conventional cardiovascular risk factors, educational attainment, presence of electrocardiographic signs of left ventricular hypertrophy and hemoglobin A1c were also included in the logistic regression analyses.
Results:
Migraine was found to be associated with female sex (Odds ratio (OR) = 3.75, p < .001), lower age (B = 0.99, p < .001), lower high-density lipoprotein cholesterol (OR = 1.23, p < .05), higher diastolic blood pressure (OR = 1.31, p < .05), and left ventricular hypertrophy (OR = 1.32, p < .05), the probability of the last one increasing with migraine attack frequency.
Conclusions:
Left ventricular hypertrophy, most probably as a consequence of migraine-related arterial hypertension and dyslipidemia, may play a role in the relationship between migraine and cardiovascular events. The nature of this finding calls for further studies.
