Abstract;The aim of this study was to evaluate the accuracy and reproducibility of brachial-ankle pulse wave velocity (ba-PWV) measured by oscillometric method, and its correlation with carotid-femoral PWV (cf-PWV) measured by the traditional applanation tonometric method, and then to analyze the major determinants of PWV. The subjects consisted of 102 patients (male 71; mean age 61+14 years). ba-PWV demonstrated good reproducibility, and significant correlation with cf-PWV (r=0.81, p<0.001). Using univariate analysis, both ba-PWV and cf-PWV had positive correlations with age, FBS, glycosylated hemoglobin and systolic blood pressure. On the other hand, stepwise multi-regression analysis showed that ba-PWV and cf-PWV had independent associations with systolic blood pressure, age and diabetes mellitus. Furthermore, it was shown that there were increases in ba-PWV and cf-PWV with increasing numbers of risk factors. Therefore, oscillometric ba-PWV can be easily and reproducibly used for quantifying arterial stiffness, and it has good correlation with tonometric cf-PWV. Oscillometric ba-PWV will be suitable for wider clinical application. (author abst.)
