Description

Pulse wave velocity (PWV) has been measured in aorta, and it is recognized that PWV is associated with the atherosclerosis. However, measurement of PWV in aorta was a little complicated.<br>The present study was conducted to examine the usefulness of noninvasive brachial-ankle pulse wave velocity (baPWV) measurements in the NTT employees who received the human dry dock in our institute. The subjects were 1434 adults (1272 males and 162 females). The baPWV were increased according to the number of atherosclerosis risk factors, including hypertension, diabetes, hyperlipidemia and obesity (p<0.0001).<br>The systolic blood pressure, age, heart rate, sex, body mass index (BMI) and triglycerides were independent factors for baPWV using multiple regression analysis. The highest correlation coefficient was systolic blood pressure. Heart rate was also highly correlated with baPWV. In addition, BMI was a negative influence factor for baPWV.<br>These results suggest that the baPWV is influenced by not only age and sex but also blood pressure and heart rate. Furthermore, it is necessary to consider the possibility that baPWV is underestimated in obese subjects.
