老年原发性高血压合并糖尿病患者动态血压及血压变异性的特点分析

目的观察老年原发性高血压合并2型糖尿病患者的动态血压(ABP)及血压变异性(BPV)的特点。方法按有无糖尿病将老年原发性高血压患者分为2组,研究组为老年原发性高血压合并糖尿病,对照组为单纯老年原发性高血压,进行24 h无创性动态血压监测,之后进行对比分析。结果老年原发性高血压合并糖尿病患者的日间平均收缩压、日间脉压、日间收缩压标准差及日间收缩压标准差变异系数与对照组相比,均显著增大(P<0.05)。结论糖尿病可导致老年原发性高血压患者ABP及BPV增大,尽早评价ABP、BPV,对患者病情判断、指导治疗及预后评估具有重要价值。

Characteristics analysis on ABP and BPV of aged essential hypertensive patients associated with diabetes mellitus

Objective To observe the features of type 2 diabetes mellitus(T2DM) on ambulatory blood pressure(ABP) and blood pressure variability(BPV) in aged essential hypertensive(EH) patients.Methods The patients were divided into two groups of aged essential hypertensive with and without diabetes mellitus.The objective group was targeted to the essential hypertensive patients associated with diabetes mellitus and the comparative group was based on the essential hypertensive patients only.Twenty-four hours recordings of ambulatory blood pressure were performed and analyzed.Results Mean daytime systolic blood pressure(dmSBP),mean daytime pulse pressure(dmPP),daytime SBP standard deviation(dSBPSD) and its coefficient of variance(dSBPCV)((P<0.05) of EH patients with diabetes mellitus(DM) were all significantly higher than those of EH patients without DM respectively.Conclusion Diabetes mellitus could lead to increase on ABP and BPV of the aged essential hypertensive patients.Therefore,the assessments on ABP and BPV should be launched early,which plays valuable role in diagnosis,treatment and prognosis.
