Rationale Pulmonary artery enlargement (PAE) is associated with exacerbations in Chronic
Obstructive Pulmonary Disease (COPD) and with survival in moderate to severe patients …

Chronic obstructive pulmonary disease (COPD) is a complex condition defined by
progressive airflow limitation in response to noxious stimuli, inflammation, and vascular …

Background Exacerbations of chronic obstructive pulmonary disease (COPD) are
associated with accelerated loss of lung function and death. Identification of patients at risk …

COPD is one of the leading causes of mortality worldwide [1]. Pulmonary hypertension has
been associated with reduced survival among individuals with COPD [2] and is an …

Rationale The relationship between pulmonary artery size with underlying pulmonary
hypertension and mortality remains to be determined in COPD. We sought to evaluate the …

Background Numerous studies have shown pulmonary artery enlargement when measured
by chest computed tomography (CT) could predict a worse outcome in chronic obstructive …

Introduction In chronic obstructive pulmonary disease (COPD), chest computed tomography
(CT) provides clinically important cardiovascular findings, which include diameter of …

Purpose Pulmonary hypertension and exercise-induced oxygen desaturation (EID)
influence acute exacerbation of COPD. Computed tomography (CT)-detected pulmonary …

Background COPD is associated with significant morbidity primarily driven by acute
exacerbations. Relative pulmonary artery (PA) enlargement, defined as a PA to ascending …

Background Relative pulmonary arterial enlargement, defined by a pulmonary artery to aorta
(PA/A) ratio> 1 on CT scanning, predicts hospitalization for acute exacerbations of COPD …
