We used pulsed Doppler echocardiography to examine the systolic ejection flow from the right ventricle in 66 patients with chronic obstructive pulmonary disease. Adequate recordings were obtained in 60 patients, in conjunction with right heart catheterization. Patients without pulmonary artery hypertension at rest (mean pulmonary artery pressure less than 20 mm Hg) underwent an exercise test which identified a group with PAH during exercise (MPAP greater than 30 mm Hg). The patients were divided into four groups: group 1, or control group: 17 healthy nonsmokers without normal respiratory function data; group 2: COPD without PAH (n = 12); group 3: PAH during exercise (n = 26); group 4: PAH at rest (n = 22). Analysis of Doppler data included time to peak velocity, right ventricular pre-ejection period, and ejection period. Pulsed Doppler echocardiography was a simple and reliable method of detecting PAH. Latent PAH, revealed by the exercise test, was accompanied by significant changes in Doppler findings, confirming the sensitivity of the method.
