血压负荷与诊室血压的关系

The Relationship between Ambulatory Blood Pressure Load and Office Blood Pressure Level

目的探讨诊室血压与动态血压负荷关系。方法选取不同血压水平受试者<90mmHg组,≥90mmHg组(≥95mmHg(轻、中度高血压))组,比较其诊室血压水平与对应的动态血压负荷值(血压负荷界值定义白天>140/90mmHg、夜间>120/80mmHg)及其相关性。结果入选53例成年(>18岁)正常血压及轻、中度高血压患者,其中男37例,女16例,平均年龄53.7±8.7岁。坐位舒张压(DBP)<90mmHg者(组1)31例,≥90mmHg者(组2)22例,其中≥95mmHg者16例。血压负荷:舒张压:组1的血压负荷为17%-29%(组间P<0.01)。组2的为75%-84%。组3的为86%-91%。组2与组3比较P>0.05。②收缩压:组1的血压负荷为33%-53%(组间P<0.01)。组2的为75%-88%。组3的为76%-90%,与≥90mmHg比P>0.05。诊室血压与其血压负荷的相关性(CC:相关系数):.舒张压:组1的CC为0.70-0.76,组2的为0.50-0.70。组3的为0.08-0.57。②收缩压:组1的为0.78-0.86,组2的为0.54-0.68,组3的为0.35-0.57。结论血压水平与血压负荷成正相关;轻中度血压与血压负荷相关性对临床更有指导意义。

Objective To investigate the relationship between ambulatory blood pressure(BP)load and office BP level.Methods To compare office BP levels with the corresponding value of BP load(The definition of BP load boundary value:the daytime>140/90mmHg,night>120/80mmHg)and their relationship.Results A total of 53 cases(> 18 years)with normal BP and mild to moderate hypertensive patients were recruited,including 37 males and 16 females,mean age 53.7± 8.7 years 31 cases with Sitting DBP< 90mmHg(group1),22 ...
