Abstract

Background: Arterial stiffness is a risk factor for symptomatic stroke, and is associated with symptomatic cerebral infarction and cognitive impairment. Hence, we hypothesized that arterial stiffness would be a significant determinant of silent cerebrovascular lesions. Methods: The subjects were 363 individuals without symptomatic cerebrovascular lesions who had their arterial stiffness assessed by brachial-ankle pulse wave velocity (baPWV) measurement. The subjects were classified into two groups by the presence or absence of lacunar infarcts, as well as into three groups by grade of white matter hyperintensity (WMH). baPWV was compared among these groups. Results: Eighty-six subjects had lacunar infarcts. Of 138 subjects with WMHs, 102 were classified as having grade 1 and 36 as having grade 2 or 3 WMHs. baPWV was significantly higher in subjects with lacunar infarcts than in those without (17.3 ± 0.3 vs. 16.4 ± 0.2 m/s). baPWV tended to increase with higher WMH grade (16.2 ± 0.2, 16.9 ± 0.3, and 17.8 ± 0.5 m/s in grade 0, 1, and 2 or 3, respectively) after adjustments for confounding factors. The adjusted odds ratio (OR) for lacunar infarcts in subjects with middle-tertile baPWV was significantly higher (OR, 2.37; 95% confidence interval, CI, 1.10-5.11) and the OR in subjects with the highest-tertile baPWV tended to be higher (OR 2.26; 95% CI 0.99-5.45) compared with the lowest-tertile baPWV. The adjusted OR for WMH tended to increase with increased baPWV. Conclusions: Arterial stiffness appeared to be associated with the presence of a lacunar infarct and WMH, independently of the risks for other cerebrovascular diseases.
