[Pulmonary artery pressure estimated by Doppler echocardiography in patients with chronic obstructive pulmonary disease].
Doppler echocardiography and right heart catheterization were performed in 18 patients with COPD. The pulmonary blood flow pattern were analysed by the pulsed doppler flowmeter. ⋯ PG correlated well with sPAP (r = 0.89, P less than 0.001) and mPAP (r = 0.92, P less than 0.001). We considered that doppler echocardiography was useful for noninvasive estimation of pulmonary artery pressure in patients with COPD.
