摘要: 摘要: 目的 探讨卧位高血压 (SP) 与颈动脉内膜中层厚度 (IMT) 的关系。方法 开滦研究是以功能社区人群为基础的心血管疾病危险因素研究。自 2006 年 6 月开始, 每 2 年进行 1 次健康体检。体检过程中对观察对象进行人口统计学资料、 吸烟、 饮酒、 体育锻炼、 服用药物情况的记录, 血压、 IMT 的测量以及三酰甘油、 超敏 C 反应蛋白、 低密度脂蛋白胆固醇等生化指标的检测。在参加第 3 次健康体检的人群中, 采用整群抽样的方法抽取年龄≥60 岁的离退休员工进行相关检查。在随机抽取的 3 064 例观察对象中, 对符合入选标准的 2 464 例进行了第 3+次体检。体检内容包括: 不同体位的血压测量、 颈部血管彩超检查、 24 h 动态血压监测、 肱踝脉搏波传导速度及尿微量白蛋白检测。采用多重线性回归分析卧位 SBP 与 IMT 的关联, 多因素 Logistic 回归分析 SP 对 IMT 的影响。结果 (1) 剔除血压、 IMT 资料缺失者, 2 220 例观察对象纳入统计分析。其中, 男 1 463 例 (65.9%)、 女 757 例 (34.1%), 平均年龄(67.29±6.09) 岁, IMT 平均厚度 (0.92±0.18) mm。(2) 卧位 SBP 与 IMT 呈正相关 (r=0.175, P<0.01)。(3) 多重线性回归分析显示: 校正其他混杂因素后, 卧位收缩压 (SBP) 每增加 1 个标准差 (+20.42 mmHg, 1 mmHg=0.133 kPa), IMT 增加 0.01 mm (P<0.05)。(4) Logistic 回归分析显示: 校正了年龄、 性别、 坐位 SBP 等因素后, SP 仍是 IMT 增加的危险因素(OR=1.37, 95%CI: 1.03~1.80), 且独立于坐位 SBP。结论 SP 是 IMT 增加的危险因素, 且独立于坐位SBP。

Abstract: Abstract:Objective To investigate the correlation of the supine hypertension (SP) with carotid intima- media thickness (IMT) in the elderly. Methods Kailuan study is a functional community-based cardiovascular risk factor study. From June 2006, there was a physical examination every two years. In the examination, demographic data, smoking, drinking, physical exercise situation and medication situation were recorded. Levels of triglyceride, high sensitivity C- reactive protein, low density lipoprotein and other biochemical indexes were observed. Using cluster random sampling, 3 064 retired employees of 60 years of age or older were selected. A total of 2 464 subjects took part in an additional examination, including the 24-hour ambulatory blood pressure monitoring, brachial-ankle pulse wave velocity, blood pressure of different positions and urine albumin. Multiple linear regression was used to analyze the correlation between supine systolic blood pressure (SBP) and IMT. Multivariate Logistic regression was used to analyze the effect of SP on IMT. Results (1) Among 2 220 participants (67.29±6.09) years, 1 463 (65.9%) individuals were male and 757 (34.1%) were females, and the average IMT was (0.92±0.18) mm. (2) There was a positive correlation between supine SBP and IMT (r=0.175, P<0.01). (3) After adjusting the confounds, supine SBP was significantly associated with IMT, with an increase of 1 SD (+ 20.42 mmHg, 1 mmHg=0.133 kPa) in SBP corresponding to an increase of IMT by 0.01 mm (P<0.01). (4) Multiple Logistic regression analysis showed that after adjusting for sitting SBP, age, gender and other factors, SP was still a risk factor of increased IMT (OR=1.37, 95%CI:1.03- 1.80), and independent of sitting SBP. Conclusion The supine hypertension is a risk factor of increased IMT, and independent of sitting SBP.
