老年非胰岛素依赖型糖尿病并高血压时血压昼夜节律改变

对比了22例健胀老华人和62例非胰岛素依赖型糖尿病(NIDDM)及合并高血压(NIDDM-HT)时的老年患者24小时动态血压昼夜节律,结果显示:健康老年人,老年NIDDM、老年NIDDM-HT者昼夜血压波动曲线均呈双峰、双谷状,老年人血压昼夜节律是存在的,但减弱;老年NIDDM血压昼夜节律消失;NIDDM-HT时夜间血压下降幅度进一步减小,提示:高龄、糖尿病、高血压均不同程度影响血压昼夜节律,而糖尿病起着主要作用,血压昼夜节律消失提示器官缺血,积极控制糖尿病及合并症以改善组织器官的缺血,是缓解血压昼夜节律消失的关键。

Day-and-Night Rhythm Change of Blood Pressure of the Aged NIDDM Patients and Those with Hypertension

The 24-hour ambulatory blood pressure day-and-night rhythm of 22 aged healthy people, 28 aged NIDDM patienls and 34 aged NIDDM patients with hypertension (NIDDM-HT) were comparied. The results showed that the blood pressure fluctuation curves for all of them had same characteristic: two -peaked and two-.valleyed. The blood pressure day-and-night rhythm for aged healthy people, did exist despite decreasing; for aged NIDDM patients, vanished. The dropping amplitude of blood pressure of NIDDM-HT patients at night was further reduced. These results mean that many factors such as age, hypertension and diabetes mellitus affect the blood pressure day-and-night rhythm to .various degrees, but the later is the major factor. The vanishing of blood pressure day-and-night rhythm suggests ischemia of organs. The key to alleviate the vanishing of blood pressure day-and -night rhythm is to control the diabetes mellitus and its complications actively and to improve the providing of blood to organs.
