老年2型糖尿病患者认知功能与血压昼夜节律变化特点

目的探讨老年2型糖尿病(T2DM)患者认知功能与24h动态血压昼夜节律变化特点。方法选择270例老年T2DM患者为糖尿病组,另选择同期健康体检者100例为对照组。对两组行24h动态血压监测,根据夜间血压下降率(ΔMBP)分为杓型(△MBP10%～20%,n=95)、非杓型(△MBP0%～<10%,n=86)、超杓型(△MBP>20%,n=47)和反杓型(△MBP<0%,n=42);用中文版简易智能状态检查表(MMSE)对所有受试者进行认知功能调查,比较各组间MMSE得分的差异。结果糖尿病组患者MMSE得分[(24.34±2.51)分]低于对照组[(28.88±3.02)分],差异有统计学意义(P<0.05)。糖尿病组中非杓型[(24.77±2.53)分]、超杓型[(23.34±2.41)分]和反杓型[(23.03±2.26)分]患者的MMSE得分均低于杓型[(26.03±2.68)分]患者,超杓型和反杓型又低于非杓型患者,差异有统计学意义(P<0.05),但超杓型和反杓型之间的差异无统计学意义。Pearson相关分析显示,糖尿病患者MMSE得分与24hSBP(r=-0.73)、24hDBP(r=-0.60)、...

Relationship between 24-hour ambulatory blood pressure circadian rhythm and cognition function in the patients of elderly type 2 diabetes

Objective To study the relationship between 24-hour ambulatory blood pressure circadian rhythm and cognition function in the patients of elderly type 2 diabetes. Methods Two hundred and seventy elderly patients of type 2 diabetes were performed 24-hour ambulatory blood pressure monitoring(ABPM),and divided into dipper group(n=95),non-dipper group(n=86),super-dipper group(n=47) and reverse-dipper group(n=42). 100 healthy subjects served as control. Cognition function were evaluated by Mini-Mental State Exami...
