White matter lesions (WMLs) are detected on brain MRI of elderly and are predictive of cognitive decline. Arterial stiffness is a cause of systolic hypertension and of increase in central pressure and might predict cardiovascular events. This study aimed to examine relationships between arterial stiffness parameters and WMLs in a large noninstitutionalized French cohort.

Methods: In a sample of 931 subjects belonging to 3C-Dijon study, WMLs were detected using automated software from which total, periventricular and deep WMLs volumes were estimated. Central systolic blood pressure (SBP) and aortic stiffness (carotid-to-femoral Pulse Wave Velocity, PWV) were assessed by tonometry. Due to differences in vascular profile, analyses were stratified by gender.

Results: 349 males and 582 females (respectively 75.0±3.7 and 75.4±3.8yrs) were included. Males had higher cardiovascular risk factors: hypertension (69.3 vs. 61.5% for females, P<0.0005) and diabetes (11.8 vs. 5.5%, P<0.001). Mean Total WMLs were similar between males and females but PWV was higher in males (15.2±3.3 vs. 14.3±3.1 m/s). In multivariable analyses adjusted for age, brain volume, heart rate, hypertension and diabetes, PWV was related to higher periventricular WMLs volume only in males (odds ratio of being in 3rd tertile of WML volume [per 1 SD increase in PWV]: 1.48; 95%CI: 1.10–2.02; P<0.05) but not in females. In contrast, in females, a higher central SBP was significantly associated with a greater volume of deep WMLs (OR: 1.27; P<0.05) but not in males.

Conclusion: These data suggest that relationships between aortic stiffness, central SBP and WMLs might differ by gender.
