摘要: 目的研究不同年龄段非酒精性脂肪性肝病(NAFLD)患者外周动脉僵硬度的变化,探讨影响动脉僵硬度增高的相关危险因素。方法根据超声检查是否存在脂肪肝将2382例健康体检者分为NAFLD组和无NAFLD组。使用欧姆龙BP-203RPE III动脉硬化检测装置同时检测左右两侧肱踝脉搏波传导速度(baPWV)值。以baPWV≥1400 cm/s为动脉僵硬度增高,采用Logistic回归分析影响动脉僵硬度增高的危险因素。结果在2382例体检者中,发现NAFLD患者935例(39.3%),在1595例男性中,检出NAFLD 患者726例(45.5%),在787例女性中,检出NAFLD患者209例(26.6%,P<0.001);20~39岁年龄段NAFLD组baPWV水平为(1340.0±180.7) cm/s,显著高于无NAFLD组【(1203.9±155.2) cm/s,P<0.001】;40~59岁年龄段NAFLD组baPWV水平为(1437.1±232.6) cm/s,显著高于无NAFLD组【(1355.8±217.9) cm/s,P<0.001】;大于60岁年龄段NAFLD组baPWV水平为(1885.8±404.0) cm/s,与无NAFLD组的baPWV水平【(1830.2±430.6) cm/s】无统计学差别(P>0.05);不同性别NAFLD对baPWV增高发生率的影响不同,以女性患NAFLD对baPWV影响较大;在1643例血压正常者,采用二分类Logistic回归分析发现,年龄、性别、NAFLD和血清总胆固醇为baPWV升高的独立危险因素。结论NAFLD患者较无NAFLD人群动脉僵硬度增高,以青中年NAFLD患者增高更为明显。NAFLD为动脉僵硬度增高的独立危险因素。

Abstract: Objective To investigate the changes and risk factors of arterial stiffness in patients with nonalcoholic fatty liver diseases(NAFLD). Methods A total of 2,382 healthy persons were enrolled for physical examination,and the NAFLD was diagnosed by ultrasound monitoring. Brachial ankle pulse wave velocity (baPWV)was determined by a domestic BP-203RPE III arterial stiffness detector,and the baPWV level≥1400 cm/s was arbitrarily believed as the increase of arterial stiffness. Risk factors of baPWV elevation were assessed by using logistic regression analysis. Results Overall,The prevalence of NAFLD was 39.3% among 2382 subjects,45.5% in 1595 men and 26.6% in 787 women,respectively;In individuals between 20 to 39 years old,the baPWV level was significantly higher in NAFLD group than in those without NAFLD[(1340.0±180.7) cm/s vs (1203.9±155.2) cm/s,P<0.001],and the increases baPWV rate was 31.4% vs. 10.5%(P<0.001);In individuals between 40 to 59 years old,the baPWV was also significantly different between NAFLD patients and non-NAFLD subjects [(1437.1±232.6) cm/s vs.(1355.8±217.9) cm/s,P<0.001],and the increased baPWV rate was 50.1% vs. 33.1%(P<0.001); However,such difference was not significant among 330 cases over 60 years old;In addition,the effect of NAFLD on baPWV increase was higher in female patients than in males;Logistic analysis showed that NAFLD,age,gender and serum total cholesterol levels were independent risk factors for baPWV increase in individuals with normal blood pressure. Conclusion The baPWV level is higher in individuals with NAFLD,especially in middle-aged ones. NAFLD is an independent risk factor for the baPWV elevation.
