【摘要】 目的探讨老年高血压病患者血压昼夜节律与颈动脉粥样硬化间的关系。方法采用无创动态血压仪对90例老年高血压患者进行24h动态血压监测,并按动态血压结果分为勺形与非勺形组;同时采用B型超声诊断仪测量患者颈动脉内膜-中层厚度(IMT)及动脉粥样斑块。结果非勺形组患者IMT(1.14±0.17mm)较勺形组患者IMT(1.01±0.19mm)增厚(t=3.55,P<0.01);非勺形组患者颈动脉粥样斑块发生率(55.56%)较勺形组患者(28.89%)明显增加(χ2=6.54,P<0.05)。结论老年高血压患者血压昼夜节律影响颈动脉粥样硬化及斑块的形成。更多还原

【Abstract】 Objective To investigate the relationship between circadian rhythms of blood pressure and carotid artery atherosclerosis in elderly hypertensive patients. Methods Ninety elderly hypertensive patients were divided into two groups dipper group and non-dipper group according to the 24h blood pressure monitoring. The intimal-medial thickness IMT of carotid artery and plaques were detected with B-mode Doppler. Results IMT of non-dipper group 1.14±0.17mmwas thicker than that of dipper group 1.01±0.19mm t=3.55 P<0.01;The rate of plaque formation in non-dipper group55.56% was higher than that in dipper group28.89% χ2=6.54,P<0.05. Conclusion The circadian rhythms of blood pressure is associated with the intimal-medial thickness of artery.更多还原
