Key result
Echo-Doppler parameters yield a ~0.92 correlation with invasive mPAP in patients with stable COLD.

Does echo-Doppler examination provide reliable noninvasive estimation of mean pulmonary artery pressure compared to right heart catheterization in patients with stable chronic obstructive lung disease?
Effect estimate: r = 0.92
Echo-Doppler examination provides reliable noninvasive estimation of pulmonary artery pressure in patients with chronic obstructive lung disease.
Marangoni et al. (2008) conducted an observational in stable chronic obstructive lung disease (COLD) (n=30). Echo-Doppler examination vs. Right heart catheterization was evaluated on Correlation of echo-Doppler parameters with mean pulmonary artery pressure (mPAP) (r = 0.92). Echo-Doppler parameters correlated strongly with mean pulmonary artery pressure (multiple correlation coefficient r = 0.92 during catheterization) in patients with stable COLD.
