老年高血压中医辨证分型与24小时血压变化水平相关性探讨

目的探讨老年高血压病中医辨证分型与血压变化水平的关系。方法采用24h动态血压检测技术，对116例老年高血压患者进行监测和中医辨证分型，观察动态血压水平，计算夜间血压下降率，以此判断血压昼夜节律变化。结果肝火亢盛证白天收缩压升高幅度最大，与气阴两虚证比较有统计学意义（P〈0．05）。气阴两虚证血压分布曲线呈非杓型的发生率较高，与其他证型比较，差异有统计学意义（P〈0．01）。结论老年高血压不同中医证型与24h血压水平和血压昼夜节律之间存在一定关系，通过中医辨证分型可以判断靶器官损害及预后。

The Relationship Between Circadian Rhythm Variation of Blood Pressure and TCM Syndrome Pattern in Essential Hypertension of Old Age

Objective To study the relationship between circadian rhythm variation of blood pressure and TCM syndrome pattem in old age essential hypertension, Methods One hundred and sixteen cases of old age essential hypertension were selected, their circadian rhythm variation of blood pressure and TCM syndromes were determined. Results The daytime systolic blood pressure was increased in the pattern with hyperactivity of liver-fire syndrome, there was difference compared with qi and yin deficiency pattern （P 〈 0.05）. The incidence of blood pressure scattered as ladle type was high in the pattern of qi and yin deficiency, and has difference with other syndromes （P〈0.01）. Conclusions TCM syndrome pattern is related to circadian rhythm variation of blood pressure in old age essential hypertension. We can infer objected organs damage and prognosis by TCM syndrome.
