高血压与外周动脉疾病患病关系的横断面研究

A cross-sectional analysis on the relationship between hypertension and peripheral artery disease

  • 摘要: 目的探讨北京市年龄≥35岁人群高血压与外周动脉疾病(PAD)的关系。方法 2013年7月至2014年12月采用分层多阶段随机抽样的方法对北京四个区县年龄≥35岁居民进行上臂血压及踝臂血压测量,共检测5 126人。结果高血压组PAD的患病率明显高于无高血压组(6.5%比3.1%,P<0.05)。Logistic回归分析结果显示,在校正年龄、性别、体质量指数(BMI)、吸烟、糖尿病、血脂代谢异常以及降压药物的使用后,与正常血压人群相比,正常高值、1级高血压、2级高血压、3级高血压其患PAD的OR(95%CI)分别为1.38(0.87~2.19)、1.68(1.04~2.73)、2.10(1.18~3.73)、5.08(2.57~10.08)。将收缩压设定为连续变量分析,结果显示收缩压每升高10 mm Hg,PAD患病风险增加19%(OR=1.19,95%CI 1.09~1.30);收缩压为120~139、140~159、≥160 mm Hg组患PAD的风险分别为收缩压<120 mm Hg组的1.29(95%CI 0.83~2.01)、1.61(95%CI 1.01~2.60)、2.75(95%CI 1.65~4.60);趋势检验P<0.001;而PAD患病风险与舒张压则关系不明显。在高血压患者中,高血压未治疗组、治疗后未达标组、治疗达标组的PAD患病风险分别为无高血压组的1.45(0.98~2.14)、1.93(1.34~2.78)、1.23(0.83~1.82)。结论高血压可增加PAD患病风险,收缩压升高为PAD的独立危险因素;控制高血压患者升高的血压可以控制PAD患病的风险。

     

    Abstract: Objective To investigate the relationship between hypertension and peripheral artery disease(PAD) in the population aged over 35 years in Beijing. Methods A multistage stratified random sampling technique was used to select the adult residents aged over 35 years in four districts and counties of Beijing area between July 2013 and December 2014. A total of 5 126 residents were randomly sampled and their upper arm blood pressure and ankle brachial blood pressure were measured. Results The prevalence of PAD was significantly higher in hypertensive individuals compared with normotensive individuals(6.5% vs 3.1%, P<0.05). After controlling for age, gender, body mass index(BMI), smoke, diabetes, dyslipidemia and the use of antihypertensive drugs, the OR(95% CI) of PAD were 1.38(0.87-2.19) in high-normal, 1.68(1.04-2.73) in grade 1 hypertension, 2.10(1.18-3.73) in grade 2 hypertension and 5.08(2.57-10.08) in grade 3 hypertension, respectively, compared with the optimal blood pressure. The risk of PAD increased by 19% with per 10 mm Hg increment of systolic blood presure(SBP). Compared with the individuals of SBP less than 120 mm Hg, the risk of PAD increased by 61%(OR: 1.61, 95% CI 1.01-2.60) and 175%(OR: 2.75, 95% CI 1.65-4.60) in those with SBP 140-159 and ≥160 mm Hg, respectively. In comparison with non-hypertension group, the OR(95% CI) of PAD were 1.45(0.98-2.14) for untreated hypertension, 1.93(1.34-2.78) for treated but uncontrolled hypertension, and 1.23(0.83-1.82) for treated and controlled hypertension,respectively. Conclusion Hypertension is associated with increment risk of PAD. Elevated SBP is the independent risk factor of PAD. Controlling elevated blood pressure in patients with hypertension may reduce the risk for PAD.
