摘要

Abstract Introduction Recent articles revealed that an increased main pulmonary artery to ascending aorta ratio (PA/A) in thorax computed tomography (CT) correlated with pulmonary hypertension, and might be linked to a high probability of chronic obstructive pulmonary disease (COPD) exacerbations. Objectives In this study, our aim was to evaluate the clinical importance of PA/A in patients with exacerbations of COPD and investigate its relationship with the number of exacerbations in 1 year or short/long‐term mortality after hospital discharge. Methods One hundred fifty‐six patients hospitalized for COPD exacerbations who fulfilled our inclusion criteria were enrolled in the study. We recorded the number of exacerbations in 1 year from hospital records, checked mortality status, and calculated the PA/A ratio from thorax CT images. Results PA/A ratio positively correlated with the number of hospitalizations for COPD exacerbations and the total number of exacerbations (hospitalized or not) in 1 year, and baseline PaCO 2 level during hospitalization ( r ?=?0.376, P ??0.001, r ?=?0.230, P ?=?0.004, and r ?=?0.328, P ??0.001, respectively). There was no relationship between mortality and PA/A. Conclusion Our study showed that PA/A was related with the number of hospitalizations and the total number of exacerbations due to COPD in 1 year. However, there was no relationship between PA/A and mortality.
