Introduction
In the current literature, several studies show that PAS (pulmonary
artery stiffness) is associated with RV (right ventricular) dysfunction,
PAH (pulmonary arterial hypertension), and disease severity in subjects
with structural cardiac disease, HIV (human immunodeficiency virus), and
chronic lung disease. Hence, our main aim was to use PAS to show the
early changes in the pulmonary vascular region in subjects with
cirrhosis.
