Abstract

Abstract

Objective The correlation between pulmonary artery diameter measured by high resolution computedtomography （HRCT） and pulmonary artery pressure measured by echocardiography in patients with chronic obstructive pulmonary disease （COPD） was investigated to find a new method to assess pulmonary artery pressure and to add a new method to the clinical assessment of the disease. Methods Seventy-seven patients with stable chronic obstructive pulmonary disease who were seen in Kunming First People’ s Hospital from May 2018 to May 2020 were set as the test group, and 50 healthy individuals who underwent health checkups in same period were selected as the control group, all of whom underwent chest HRCT to measure right pulmonary artery diameter, left pulmonary artery diameter, and main pulmonary artery diameter, and also underwent cardiac ultrasound to measure right ventricular diameter, pulmonary artery pressure, and main pulmonary artery diameter. The data collected were analyzed for correlation. Results The data of left and right pulmonary artery diameter and main pulmonary artery diameter measured by HRCT in the COPD group were larger than those in the normal group （P < 0.05）, and there were differences in the data of right pulmonary artery diameter and main pulmonary artery diameter between the COPD groups （P < 0.05）, but not in the left pulmonary artery diameter （P > 0.05）; the right intraventricular diameter and pulmonary artery pressure measured by echocardiography were different between the COPD groups （P < 0.05）. The right intraventricular diameter, pulmonary artery pressure, and main pulmonary artery diameter were significantly correlated with the left and right pulmonary artery diameters and main pulmonary artery diameter by Pearson linear correlation analysis （P < 0.05）, and all were positively correlated. Conclusio There is a significant correlation between the values of pulmonary artery pressure and the values of pulmonary artery diameter in patients with COPD. HRCT measurement of pulmonary artery trunk diameter and right pulmonary artery diameter can be used as a method to assess pulmonary artery pressure.
