Thirty patients with stable chronic obstructive lung disease (COLD) underwent an echo-Doppler examination before and during right heart catheterization. No statistically significant differences between observations for any of two-dimensional echo-Doppler parameters were found. The measurement of all parameters taken during the catheterization correlated better with mean pulmonary artery pressure (mPAP) than those taken before. This difference was most evident for the isovolumetric acceleration time (r = 0.71 before versus r = 0.85 during the catheterization) and relaxation time (r = -0.75 before versus r = -0.87 during the catheterization). The multiple correlation coefficient for all measured parameters and mPAP was 0.83 before and 0.92 during the catheterization. In conclusion, in patients with COLD, it appears possible to get reliable information about PAP using noninvasive techniques.
30例稳定期慢性阻塞性肺疾病（COLD）患者在右心导管插入术前和术中接受了超声多普勒检查。二维超声多普勒参数的任何观察值之间均未发现统计学上的显著差异。导管插入术期间测量的所有参数与平均肺动脉压（mPAP）的相关性比术前更好。等容加速时间（导管插入术前r = 0.71，导管插入术中r = 0.85）和舒张时间（导管插入术前r = -0.75，导管插入术中r = -0.87）的差异最为明显。所有测量参数与mPAP的多重相关系数在导管插入术前为0.83，在导管插入术中为0.92。总之，对于COLD患者，似乎可以使用非侵入性技术获得有关肺动脉压的可靠信息。
