Is the pulmonary artery to aorta ratio a prognostic indicator in acute exacerbation of COPD?

ABSTRACT:

Introduction and aim

To evaluate whether the pulmonary artery to ascending aorta diameter ratio (PA/A ratio), measured via thoracic computed tomography (CT), is associated with poor clinical outcomes and mortality in patients hospitalized for acute exacerbation of chronic obstructive pulmonary disease (COPD).

Methods

This retrospective study included 486 COPD patients admitted between 2017 and 2023 with available thoracic CT or CT angiography at admission. PA and aortic diameters were measured by radiologists, and PA/A ratios were calculated. Clinical parameters including blood gas values, need for non-invasive (NIMV) or invasive mechanical ventilation (IMV), and mortality data were collected. Statistical analyses included Mann-Whitney U, Chi-square, Spearman correlation, an
