老年糖尿病合并原发性高血压患者24小时血压昼夜节律变化

目的　观察老年 2型糖尿病合并原发性高血压患者动态血压昼夜节律的变化。方法　按有无糖尿病将老年原发性高血压患者分为两组 ,A组为糖尿病合并原发性高血压组 ,B组为原发性高血压组 ,进行 2 4h无创性动态血压监测。结果　老年糖尿病合并原发性高血压患者夜间收缩压明显增高 (P <0 .0 1) ;其血压昼夜差值、节律变化、以及夜间心率变化与老年单纯性高血压病组比较 ,差异有显著性意义 (P <0 .0 5 )。结论　糖尿病合并原发性高血压患者夜间血压及心率下降幅较单纯高血压患者明显减少 ,提示糖尿病合并原发性高血压时对患者的昼夜血压调节功能损害较大

Circadian 24-hour rhythm of blood pressure fluctuation in senile diabetics accompanied with primary hypertension

Objective To observe circadian 24-hour rhythm of blood pressure fluctuation in senile patients with diabetes type Ⅱ accompanied with hypertension.Methods The cases of senile primary hypertension were divided into groups in terms of having or not having diabetes.The blood pressure was monitored successively and non-invasively.Results The night systolic pressure of senile diabetic patients accompanied with primary hypertension rose remarkably, P<0.01, the difference of blood pressure between day and night and the rhythm change showed remarkable difference in comparison with those of senile patients suffering from hypertension alone.Conclusion The nocturnal blood pressure and heart rate of the patients suffering from diabetes and hypertension are kept at higher level as compared with those of the patients with hypertension alone, indicating that the function of diurnal and nocturnal blood pressure regulation is obviously damaged.
