【摘要】 目的:探讨老年高血压患者血压变异性与左室肥厚的关系。方法:对老年高血压组32例,高血压治疗达标组30例,正常血压组24例,分别采用动态血压记录仪监测动态血压,计算出24小时、白天、夜间血压变异性,采用超声心动图测量左室内径,室间隔内径和左室后壁厚度,计算出左室重量及左室重量指数。结果:高血压组血压变异性、左室重量、左定重量指数高于高血压治疗达标组和正常组（P<0.05）,高血压治疗达标组血压变异性、左室重量高于正常组（P<0.05）。结论:24小时血压变异性与血压平均水平有关,血压变异者更易发生靶器官损害和左室肥厚。更多还原

【Abstract】 Objective: To study the correlation between blood pressure variability and left ventricular hypertrophy in elderly patients with hypertension. Methods: Ambulatory blood pressure system was applied to measure average BP, BP variability. Left ventricular internal diameter, the thickness of ventricular septum and left ventricular posterior wall were taken using echocardiography so as to calculate left ventricular weight (LVM) and left ventricular weight index (LVMI) in 32 elderly patient with hypertension (group Ⅰ), 30 cases achieved treatment goals of blood pressure (group Ⅱ) and 24 controls (control group). Results: BP variability, LVM and LVMI in groupⅠwere higher than those of group Ⅱ and control group (P<0.05). BP variability, LVM in group Ⅰ were higher than those of control group (P<0. 05). Conclusion: There is correlation among BP variability and average BP, LVH.更多还原
