【摘要】：探讨中心动脉与肱动脉舒张压(DBP)、收缩压(SBP)、脉压(PP)、心内膜下心肌活力率(SEVR)、波形参数(k)、每搏输出量(SV)、心排量(CO)、外周阻力(RS)等参数的相关性.通过对40例临床需要进行冠状动脉造影患者的有创中心动脉参数与肱动脉参数进行相关分析,将直接测得的中心动脉参数分别与通过回归方程、建立模型估算的中心动脉参数进行配对t检验和Bland-Altman图示.结果表明:除k值外的所有中心动脉与肱动脉参数均相关;两种估算方法 DBP,SEVR一致性相当,其回归方程用Y'=a+bx表示;DBP,SBP,PP,SEVR,SV,CO也可通过回归方程估算,但准确性比传递函数差.
[Abstract]:To investigate the correlation between central artery and brachial artery diastolic blood pressure (DBP), systolic pressure (SBP), pulse pressure (PP), subendocardial myocardial viability (SEVRV), waveform parameter (KV), cardiac output volume (SVV), cardiac output volume (CO), peripheral resistance (RS) and so on. By analyzing the correlation between the parameters of the invasive central artery and the brachial artery in 40 patients with coronary arteriography, the parameters of the central artery were measured directly and the regression equation was used to analyze the relationship between the parameters of the central artery and the brachial artery. The estimated central artery parameters were matched t test and Bland-Altman diagram. The results show that all the central arteries except k value are correlated with brachial artery parameters, and the two estimation methods are consistent with each other, and the regression equation can be used to estimate DBP / SBP / PPSE VRSVV / CO, but the accuracy is lower than that of transfer function.
