To investigate the relationship between brachial ankle pulse wave velocity (BaPWV), radial augmentation index (radial AI), ankle-brachial index (ABI), and carotid intima-media thickness (carotid-IMT), and to study the prevalence and characteristics of atherosclerosis and peripheral arterial disease in a Chinese population of Inner Mongolia.
Participants were recruited from Inner Mongolia in China through cluster multistage and random sampling. BaPWV, radial AI, ABI, and carotid-IMT values were measured in each subject.
A total of 1,236 participants from natural population of Inner Mongolia in China were included in this study. The average ABI value was 1.082 ± 0.093. The average values of common carotid, internal carotid, and carotid artery bifurcation IMT were 0.70 ± 0.21, 0.77 ± 0.24, and 0.78 ± 0.25 mm, respectively. The average value of BaPWV was 1450.5 ± 301.5 cm/s. The average value of radial AI was 78.9 ± 16.8 %. BaPWV, radial AI, and carotid-IMT values were positively correlated with ages significantly. BaPWV values were positively correlated with radial AI significantly. BaPWV values were positively correlated with values of common carotid, internal carotid, and carotid artery bifurcation IMT respectively. Radial AI values were positively correlated with the values of common carotid, internal carotid, and carotid artery bifurcation IMT respectively. A U-shaped relationship was observed that radial AI values were decreased at first and then increased as ABI values increased.
The data suggests that BaPWV, radial AI, and carotid-IMT values are positively correlated with each other, and AI values are correlated with ABI values in a U-shaped curve in a Chinese population of Inner Mongolia.
探讨肱踝脉搏波速度（BaPWV）、桡动脉增强指数（radial AI）、踝臂指数（ABI）与颈动脉内膜中层厚度（carotid-IMT）之间的关系，并研究中国内蒙古人群动脉粥样硬化和外周动脉疾病的患病率及特征。
通过整群多级随机抽样在中国内蒙古招募参与者。测量每位受试者的BaPWV、radial AI、ABI和carotid-IMT值。
本研究共纳入1236名来自中国内蒙古自然人群的参与者。平均ABI值为1.082±0.093。颈总动脉、颈内动脉和颈动脉分叉处IMT的平均值分别为0.70±0.21、0.77±0.24和0.78±0.25mm。BaPWV的平均值为1450.5±301.5cm/s。radial AI的平均值为78.9±16.8%。BaPWV、radial AI和carotid-IMT值与年龄显著正相关。BaPWV值与radial AI显著正相关。BaPWV值分别与颈总动脉、颈内动脉和颈动脉分叉处IMT值正相关。radial AI值分别与颈总动脉、颈内动脉和颈动脉分叉处IMT值正相关。观察到一种U型关系，即随着ABI值增加，radial AI值先降低后升高。
数据表明，在中国内蒙古人群中，BaPWV、radial AI和carotid-IMT值相互之间呈正相关，且AI值与ABI值呈U型曲线相关。
