Objectives To explore the significance of noninvasive central blood pressure detection in blood pressure management and vessel function assessment of hypertension.MethodsA total of 348 subjects were recruited in the study and A-pulse CASP software were derived to measure the parameters of CASP and vessel function. The recruited subjects were divided into different groups for analysis according to age and disease.Results①CASP in hypertension group were both higher than those in normal group, while RAI and PRT lower.②Hypertensive patients of which brachial blood pressure were controlled have lower CASP and RAI than those above the level.③ Hypertensive patients whose brachial blood pressure were controled have significantly higher CASP than normal subjects.Conclusions Central blood pressure is more reflective of actural blood pressure and vessel function. Enhanced control of CASP in hypertensive patients contributes to improving vessel compliance.%目的 探索无创中心动脉压检测对血压管理及评估血管功能的意义.方法 入选对象348例.采用BPro?动脉脉搏波采集设备结合A-PULSE CASP?中心动脉压应用软件检测,按年龄、疾病等分组统计,探讨无创中心动脉压检测在血压管理及评估血管功能方面的临床意义.结果①高血压组中心动脉收缩压(Central Aortic Systolic Pressure,CASP)显著高于正常组;反射波增强指数(Radial Augmentation Index,RAI)、收缩期巅峰与动脉反射波时差(Peak Relative Time, PRT)小于正常组.②血压控制达标组CASP、RAI均小于未达标组.③血压控制达标组CASP较正常组偏高.结论 CASP能更准确地反映实际血压,控制中心动脉压有助于改善血管顺应性.
