右下肺动脉直径联合肺动脉压力值在肺心病的诊断价值 postprint

Abstract: Objective To explore the diagnostic value of pulmonary artery pressure value combined with right lower pulmonaryartery diameter in pulmonary heart disease. Methods Randomly selected from June 2014 to May 2016, 49 cases withpulmonary heart disease diagnosed as pulmonary heart disease group; 31 cases with chronic obstructive pulmonary diseasewere treated with the same time as the COPD group; and 30 cases of normal adults as control group. CT was used to measurethe diameter of the right lower pulmonary artery in each group, and the pulmonary artery pressure was measured byechocardiography. The indexes of each group were compared and the relationship between the indexes and the course ofpulmonary heart disease were analyzed. Results With the development of pulmonary heart disease, the diameter of the rightpulmonary artery increased, there were significant differences in the diameter of the main pulmonary artery and pulmonaryartery pressure between the control group and the pulmonary heart disease group. Pulmonary heart disease group and COPDgroup, the control group of the right lower pulmonary diameter/pulmonary artery pressure value comparison, the differencewas statistically significant. Conclusion The change of the right lower pulmonary diameter and pulmonary pressure value arerelated to the degree of the disease course of pulmonary heart disease. The value of right lower pulmonary diameter andpulmonary artery pressure value is a CT monitoring index in the diagnosis of pulmonary heart disease and its process.
