摘　　要：目的：比较目前通用的无创中心动脉压检测仪A-PULSE CASPro和SphygmoCor测量中心动脉压的相关性和稳定性。方法：450名男性志愿者，年龄19～23（22±1）岁；采集病史、记录一般情况；告知并签署知情同意；坐位休息10 min后测量右上肢肱动脉血压、分别用A-PULSE CASPro和SphygmoCor测量中心动脉压；记录数据。结果：A-PULSE CASPRO与SphygmoCor 测量的中心动脉压平均差值为1.57 mmHg（1 mmHg=0.133 kPa）和标准偏差为2.53 mmHg。采用Bland-Altman评价两种方法测量中心动脉压的偏差是在（5±8） mmHg范围之内。两种设备的线性回归方程为Y=0.9231＊X＋9.9341。A-PULSE CASPro和SphygmoCor测量的中心动脉压数值一致性好，R2为0.9123。结论： A-PULSE CASPro和SphygmoCor测量中心动脉压数值基本一致，相关性好，稳定性好。AIM：To compare the stability, accuracy and correlation between two common noninvasive central aortic pressure gauges （A-PULSE CASPro and SphygmoCor） in measuring central aortic systolic pressure. METHODS： Four hundred and fifty male volunteers, aged 19-23 years with an average of （22±1）, were enrolled in this study. After medical history was acquired, basic data was recorded and the volunteers signed the informed consent, the right brachial artery blood pressure was measured after 10 minutes’ sitting rest. Then, A-PULSE CASPro and SphygmoCor were used separately to measure the central aortic systolic pressure and the data were recorded. RESULTS： The mean absolute deviation of the central aortic systolic pressure value measured by A-PULSE CASPro and SphygmoCor was 1.57 mmHg and the standard deviation was 2.53 mmHg. The linear regression equation of the two instruments was Y=0.9231＊X＋9.9341. Good consistency of the central aortic systolic pressure value was obtained by both A-PULSE CASPro and SphygmoCor, with the value of R2=0.9123. CONCLUSION： The central aortic systolic pressure values measured by both A-PULSE CASPro and SphygmoCor are matched. The errors of the two instruments with the evaluation of Bland-Altman are within the range of （5±8） mmHg. The predictive indication of the central aortic systolic pressure is more obvious than that of the peripheral systolic pressure in forecasting the cardiovascular events. Noninvasive central blood pressure measurement has important clinical value in the diagnosis of hypertension and blood pressure management.
