Brachial-Ankle Pulse Wave Velocity is Related to the Total Cerebral Small-Vessel Disease Score in an Apparently Healthy Asymptomatic Population.
Journal of Stroke and Cerebrovascular Diseases : the Official Journal of National Stroke Association 2020 November
INTRODUCTION: Cerebral small-vessel disease (CSVD) is an extensive cerebrovascular disease associated with many poor outcomes. Previous studies have shown that brachial-ankle pulse wave velocity (baPWV) is related to various neuroimaging signatures, but its association with the total CSVD burden remains unknown. We aimed to explore whether baPWV is related to the total CSVD score and to establish a cutoff for detecting the presence and severity of CSVD, which may guide clinical preventive measures.
METHODS: We retrospectively selected 684 neurologically healthy participants to explore correlations between baPWV and the total CSVD score and each of its components (lacunes, white matter hyperintensity (WMH), perivascular space (PVS), and cerebral microbleeds (CMBs)). Subsequently, we established two receiver operating characteristic (ROC) curves to study the effectiveness of baPWV in predicting CSVD (scores 1-4) and severe CSVD (scores 3-4).
RESULTS: The median baPWV was 13.16 m/s, which increased significantly with increasing scores (0-4). BaPWV was significantly higher among persons with each component of the total CSVD score than among those without any components. Multivariable ordinal logistic regression analyses showed that a one-unit (m/s) change in baPWV significantly increased the total CSVD score by 0.012. The optimal baPWV cutoffs for detecting CSVD and severe CSVD were 13.12 m/s and 15.63 m/s, respectively.
CONCLUSIONS: BaPWV was positively correlated with the total CSVD score, suggesting that baPWV measurement is a useful method for early diagnosis of CSVD, which may contribute to preventing and controlling CSVD progression in the general population of China.
