血压水平及其变异性与预后的关系

目的 探讨高血压病（EH）患者血压水平和变异性与预后的关系。方法采用美国Accutroker Dx型无创性全自动血压监测仪，对274例EH患者进行24小时动态血压监测，将监测值和临床资料进行综合分析和统计学处理。结果（1）随着血压级别的升高，反映血压变异性（BPV）的收缩压和舒张压各参数均显著升高：（2）随着血压级别的升高，勺型发生率降低，而靶器官损害（TOD）及临床伴随情况（ACC）发生率上升；（3）在二级和三级高血压中，24小时和日间收缩压变异系数与影响预后的因素呈显著正相关。结论随血压水平增高，BPV增大，TOD和AOC发生率也增高。当血压水平较高时，BPV越大，预后越差。

The relationship between the level and variability of blood pressure and prognosis

Objective To evaluate the relationship between the level and variability of blood pressure and prognosis in patients with Essential Hypertension(EH).Methods Noninvasive blood pressure recorder (Accutroker Dx)was used to carry out 24 hours ambulatory blood pressure monitoring in 274 patients with EH.The statistical analysis was done in the obtained readings and clinical data.Results First,when the level of blood pressure was increased,the indexes of systolic and diastolic pressure on blood pressure variability all were increased.Second,when the level of blood pressure was increased ,the incidence of ladle-type was decreased,and the incidence of Target Organ Damage(TOD)and Accompanying Clinical Condition(ACC)was decreased.Third,the significant positive correlation was observed between 24 hours and day systolic blood pressure variability coefficient and the factor of effect on prognosis.Conclusion When the level of blood pressure was increased,blood pressure variability(BPV)was increased,and the incidence of TOD and ACC was also increased.When the level of blood pressure was higher,the larger BPV were,the poorer prognosis were.
