老年高血压患者血压变异性与颈动脉粥样硬化的关系

The Analysis of Blood Pressure Variability in Old Patients with Hypertension Associated with Carotid Atherosclerotic

目的:研究老年高血压患者血压变异性与颈动脉粥样硬化的关系。方法:运用24小时动态血压监测,对98例老年高血压患者进行动态血压监测,测得24小时及白昼、夜间血压平均值、血压变异性,并进行颈动脉彩色多普勒检查,根据颈动脉内中膜厚度及动脉斑块形成情况分为动脉粥样硬化组(AS组)和非动脉粥样硬化组(非AS组)。对比2组甘油三酯(TG)、总胆固醇(TC)、低密度脂蛋白(LDL-C),分析老年高血压患者血压变异性与颈动脉粥样硬化的关系。结果:AS组较非AS组的24小时、白昼及夜间收缩压和舒张压平均值,以及相应变异性均显著增高(P<0.01)。TG、TC、LDL-C无统计学差异。结论:老年高血压患者血压变异性与颈动脉粥样硬化有关。

Objective：To analyze the relationship between carotid atherosclerotic, blood pressure variability in old patients with hypertension. Methods：98 old patients With hypertension were detected by ambulatory blood pressure monitoring（ABPM）, measured the blood pressure average value and the blood pressure variability of 24 h, day, and night, detected with color doppler, by IMT evidence divided it to atherosclerosis group and non - atherosclerosis group. Analyzed the relationship between carotid atherosclerotic, blood pressure variability in old patients with hypertension. Results：The blood pressure average value and the blood pressure variability of 24 h, day, and night in carotid atherosclerotic group were higher than other （P 〈 0. 01 ）. Conclusion：The blood pressure variability concem with carotid atherosclerotie in old patients with hypertension.
