Abstract: Introduction: Pulmonary hypertension (PH) comprises a heterogeneous group of diseases characterized by a sustained elevation of pressure in the pulmonary circulation, which imposes a progressive hemodynamic burden on the right ventricle, increasing the risk of right heart failure and premature death. Objectives: The general objective of this study was to determine the association between the pulmonary artery diameter measured by chest computed tomography angiography and the pulmonary artery pressure values obtained by echocardiography. The specific objectives were to measure the pulmonary artery diameter on CT angiography, estimate pulmonary pressures using echocardiography, and analyze the correlation between CT angiography and echocardiographic findings in the evaluation of pulmonary hypertension. Methodology: A retrospective observational study was conducted in adult patients with clinical suspicion of PH, evaluated by transthoracic echocardiography and chest CT angiography. Echocardiographic variables (estimated systolic pulmonary artery pressure) and tomographic variables (main pulmonary artery diameter and pulmonary artery-to-aorta ratio) were analyzed. Statistical analysis included association tests (χ²), correlation analysis (Pearson), and logistic regression. Results: A total of 47 patients were included, with female predominance. A statistically significant association was observed between pulmonary artery dilation on CT angiography and elevated systolic pulmonary artery pressure estimated by echocardiography (p < 0.05). No significant linear correlation was identified between continuous variables (r = 0.134; p = 0.369). Conclusions: This study determined the existence of a direct correlation between abnormal pulmonary artery diameter and elevated mean pulmonary arterial pressure measured noninvasively by echocardiography, which was statistically significant with a P value < 0.001. Recommendations: Further studies are recommended incorporating variables such as prior diseases and surgical history to assess potential modifications in the obtained results. Additionally, future studies should employ non-mixed variables with improved confounder control and a larger amount of complete data to allow a more precise evaluation of this relationship.
