摘要
目的 探讨脉搏波传导速度(pulse wave velocity,PWV)和踝臂指数(ankle brachial pressure index,ABI)在飞行人员动脉硬化早期检测中的应用价值.方法 应用动脉硬化检测仪,检测107例飞行人员的PWV和ABI,并与107例地方体检人员进行对比分析.结果 飞行人员组发现PWV异常10例(9.3%),对照组发现36例(33.6%);对照组发现1例ABI异常,而飞行人员组未见ABI异常;两组人群PWV均值随着年龄的增长而增大(F=3.314～13.819,P＜0.05),但飞行人员PWV均值显著低于同年龄组一般人群(t=2.187～4.208,P＜0.05).线性回归分析结果表明,飞行人员PWV与年龄、血压、腰围和体重指数显著相关(β=0.439～0.634,P＜0.01).结论 年龄、血压、腰围或体重指数的增加是飞行人员大动脉弹性降低的主要危险因素,PWV可以作为飞行人员血管早期病变检测与评价的功能指标.
Objective To explore the value of using pulse wave velocity (PWV) and ankle brachial pressure index (ABI) to detect the early arteriosclerosis in flying personnel. Methods PWV and ABI were detected in 107 cases of flying personnel by arteriosclerosis detector and 107 civil personnel were examined as control group. Results 10 cases (9.3%) of abnormal PWV were found in flying personnel group while 36 cases (33.6%) found in control group. Only one abnormal ABI case was in control group but in flying personnel group. The mean PWV of both groups' showed significant increase with the age growing (F= 3. 314-13. 819, P＜0. 05). The mean PWV of flying personnel group was significantly lower than that of the control group in same age segment (t= 2. 187-4. 208,P＜0.05). Linear regression analysis showed that PWV was closely related to the age, blood pressure, waist circumference (WC) and body mass index (BMI) in flying personnel group (β=0. 439-0. 634, P＜0. 05). Conclusions The increases of age, blood pressure and WC or BMI are the major risk factors of causing aorta elasticity decreased in flying personnel. It is suggested that the PWV would be an applicable functional index in early diagnosis of vascular pathological changes and in medical evaluation.
