【摘要】 目的研究原发性高血压（ＥＨ）患者血压昼夜节律改变与高血压病期及严重程度的关系。方法应用无创动态血压监测系统记录２４ｈ血压并分析正常人组（５２例）、高血压Ⅰ期（４８例）、Ⅱ期（８５例）、Ⅲ期（３２例）患者白昼与夜间的血压变化。结果Ｉ～Ⅲ期患者夜间收缩压（ＳＢＰ），舒张压（ＤＢＰ）下降率分别为１８％，１５％；８％，７％；１％，２％；昼夜节律紊乱Ⅰ期６％，Ⅱ期３６％，Ⅲ期８４％。Ⅰ期夜间ＳＢＰ下降率高于正常人组（Ｐ＜０．０５）。结论夜间血压下降率可以做为临床上高血压程度及靶器官受损评估的一项指标。更多还原

【Abstract】 Aim \ To study the relationship between circadian blood pressure and target organs damages.\ Methods\ 52 normotensive and 165 essential hyperensive(EH) subjects in different stages were investigated with noninvasive ambulant blood pressure mornitoring(ABPM).\ Results\ That in night time the decline rate of systolic blood pressure(SBP) and diastolic blood pressure(DBP) were 18% and 15% in stage Ⅰ,8% and 7% in stage Ⅱ,1% and 2% in stage Ⅲ respectively. Day and night rhythmic disorder occur in 6% in Ⅰ,36% in Ⅱ,84% in Ⅲ.\ Conclusion\ This study comfirms that non dipper phenomena may be considered as a index for evaluating the severity of EH and target organs involvement.更多还原
