在一组临床上没有动脉硬化闭塞症的男性中，经皮获得了人股动脉壁特性的测量结果。根据年龄将患者分为三组：35岁以下，35-60岁和60岁以上。使用超声回波跟踪系统测量直径和直径变化。通过听诊法测定动脉脉压。结果表明，动脉随着年龄的增长而变得更硬。压力-应变弹性模量（Ep）从年轻组的2.6 ± 0.3 SEM × 106 dynes/cm 2变化到老年组的6.3 ± 1.0 SEM × 106 dynes/cm 2。这些值与其他研究者使用侵入性和体外技术报告的值相似。虽然统计学比较表明组间存在显著差异，但组内差异相当大。并不罕见，Ep值从个人在最古老的组落在范围内获得的值在年轻的组。
Measurements of human femoral arterial wall properties have been obtained transcutaneously in a group of males who were clinically free of arteriosclerosis obliterans. The patients were divided into three groups according to age: under 35, 35-60, and over 60 years. Diameter and changes in diameter were measured using an ultrasonic echo-tracking system. Arterial pulse pressure was determined by the auscultatory method. The results suggest that arteries become stiffer with age. The pressure-strain elastic modulus (Ep) varied from 2.6 ± 0.3 SEM × 106 dynes/cm2 in the young group to 6.3 ± 1.0 SEM × 106 dynes/cm2 in the old group. These values are similar to those reported by other investigators using invasive and in vitro technics. Although statistical comparisons indicate a significant difference between groups, there was considerable variation within the groups. Not infrequently, values for Ep obtained from individuals in the oldest group fell well within the range of the values obtained in the young group.
