【摘要】 目的 探讨老年高血压患者血压晨峰与动脉缓冲功能的关系。方法 根据24 h ABPM结果将97例老年患者分为两组,晨峰变异>10 mm Hg为晨峰组,余非晨峰组。所有受试者行24 h动态血压和血管超声检查测得动脉横断面的顺应性(CSC)、动脉可扩张系数(VD)和内皮依赖血管扩张功能(FMD)。结果 晨峰组24 h、白昼、夜间平均收缩压均保持较高水平,显著高于非晨峰组( P0.05),晨峰组IMT明显高于非晨峰组,差异有统计学意义(P [3] Kaneda R Kario K, Hoshide S, et al.Morning blood pressure hyper-reactivity is an independent predictor for hypertensive cardiac hypertrophy in a community-dwelling population Am J Hypertension,2005,18:1528-1533.
