Key result
CT-derived PA/Ao ratio is linked to COVID-19 clinical severity.
Why the study?
Definitive diagnosis of pulmonary hypertension in COVID-19 is difficult due to infection spread risk, necessitating noninvasive prediction methods.
Does plain computed tomography-determined pulmonary artery-to-aorta ratio predict clinical severity in patients with COVID-19?
Does plain computed tomography-determined pulmonary artery-to-aorta ratio predict clinical severity in patients with COVID-19?
Plain computed tomography-determined pulmonary artery-to-aorta ratio is being assessed as a noninvasive predictor of COVID-19 clinical severity.
Should not yet change practice; leaves open predictive utility of PA/Ao ratio pending prospective validation.
Coronavirus disease (COVID-19) is associated with pulmonary hypertension due to pulmonary embolism, which affects subsequent outcomes. However, definitive diagnosis of pulmonary hypertension is difficult because of the risk of spreading the infection. Here, we assess the utility of plane computed tomography in noninvasively predicting the clinical severity of COVID-19.
