The results suggest that there is considerable difference in the measured BP in the right and left arms and that large differences in the absolute SBP are associated with risk factors for arteriosclerosis such as hypertension, hypercholesterolemia, obesity, metabolic abnormalities and low ABI.

These results suggest that the peripheral AI(r) measurement is clinically useful in predicting LVH. Enhanced wave reflection may be related to the development of LVH in hypertensive patients.

Although the SDPTG depends on various factors in a manner different from BAPWV, it may be useful for detecting vascular aging accelerated by hypertension.

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.
