控制血糖对老年原发性高血压合并2型糖尿病患者血压变异性的影响

目的探讨控制血糖对老年原发性高血压（EH）合并2型糖尿病（T2DM）患者血压变异性（BPV）的影响。方法临床确诊60例EH合并T2DM老年患者,糖化血红蛋白（HbA1c）含量检测均〉8.0 mmol/L,在给予原有抗高血压药物治疗同时,行控制血糖治疗3月后复查HbA1c,根据检测指标分为2组：A组为HbA1c达标组（HbA1c〈7.0 mmol/L）,B组为HbA1c未达标组（HbA1c〉7.0 mmol/L）。控制血糖治疗前后分别进行动态血压测定,比较患者BPV的变化。以各时间段血压的标准差（SD）作为血压变异的指标：24 h收缩压变异（24hSSD）和24 h舒张压变异（24hDSD）、白昼收缩压变异（dSSD）和舒张压变异（dDSD）、夜间收缩压变异（nSSD）和舒张压变异（nDSD）。结果 （1）EH合并T2DM患者,行控制血糖治疗HbA1c达标组治疗后与治疗前比较,24hDSD、dDSD、nDSD无显著差异（P〉0.05）,24hSSD、dSSD、nSSD有显著差异（P〈0.05）。（2）EH合并T2DM患者,行控制血糖治疗HbA1c未达标组治疗后与治疗前比较,患者的24hSSD、24hDSD、dSSD、dDSD、nDSD均无显著差异（P〉0.05）,nSSD有显著差异（P〈0.05）。（3）EH合并T2DM患者24hSSD、24hDSD变化与HbA1c含量呈正相关（r=0.531、0.667,P〈0.05）。结论在原有抗高血压药物治疗同时,控制血糖治疗可显著改善EH合并T2DM患者的BPV,改善其心血管系统血流动力学,从而减少心血管病并发症。

Effects of glucose control on blood pressure variability in elderly hypertensive patients with type 2 diabetes mellitus

Objective To study the effects of glucose control on blood pressure variability(BPV) in elderly essential hypertensive(EH) patients with type 2 diabetes mellitus(T2DM).Methods Sixty elderly patients with EH combined with T2DM whose HbA1c were more than 8.0 mmol/L were enrolled in this study.The patients received 3 months' glucose control and routine antihypertension treatment,and then underwent HbA1c measurement.According to the level of HbA1c,the patients were divided into group A(HbA1c <7.0 mmol/L) and gr...
