COPD + PH: pulmonary artery diameter in patients with COPD and pulmonary hypertension; COPD: pulmonary artery diameter in patients with COPD and normal pulmonary artery pressure; transverse systolic : transverse systolic diameter; axial systolic : axial systolic diameter; and systolic area: sectional systolic area.
Mean ± SD; : level of probability, n.s.: not significant; right: right pulmonary artery; left: left pulmonary artery; pulsatility: ratio between systolic and diastolic cross-sectional areas. Number of observations: 20 for each set.
