Comparison of Atherosclerotic Indicators Between Cardio Ankle Vascular Index and Brachial Ankle Pulse Wave Velocity

Background: Aortic pulse wave velocity has been used for evaluating atherosclerosis. Recently, the development of the volume plethysmographic method has made it possible to easily measure the index of the pulse wave velocity. The brachial ankle pulse wave velocity and cardio ankle vascular index are used for estimating the extent of atherosclerosis. The diagnostic usefulness of these indexes in predicting coronary artery disease was examined. Methods: The brachial ankle pulse wave velocity, the cardio ankle vascular index, and the high-sensitivity C-reactive protein were measured in 696 patients who had chest pain and underwent coronary angiography. Measurement values of brachial ankle pulse wave velocity were compared with those of cardio ankle vascular index in terms of the baseline covariates and the number of major coronary vessels involved (vessel disease). Results: The brachial ankle pulse wave velocity was significantly correlated with age, systolic blood pressure, and diastolic blood pressure but ...
