There is a lack of knowledge on the association between cardiovascular risk factors and intracranial atherosclerotic lesion burden in the Caucasian population. In this study 105 Caucasian stroke and TIA patients underwent 7T intracranial vessel wall imaging within 3 months after symptom onset. Poisson regression analysis showed that older age, higher systolic blood pressure, diabetes mellitus and a higher SMART risk score (wherein multiple cardiovascular risk factors are combined) were associated with a higher number of vessel wall lesions. Controversially, dyslipidemia and cigarette smoking were not associated with the severity of intracranial vessel wall lesions.
