Abstract

Introduction In the current literature, several studies show that pulmonary artery stiffness (PAS) is associated with right ventricular (RV) dysfunction, pulmonary arterial hypertension (PAH), and disease severity in patients with structural heart disease, human immunodeficiency virus (HIV), and chronic lung disease. Hence, in this study, we aimed to use PAS to show the early changes in the pulmonary vascular bed in patients with cirrhosis. Material and Methods In this prospective, cross-sectional study, 39 subjects who were being followed up with cirrhosis and 41 age- and sex-matched healthy participants were enrolled. For each case, the PAS value was calculated by dividing mean peak velocity of the pulmonary flow by the pulmonary flow acceleration time (PfAT). Results The measured PAS was 23.62 ± 5.87 (Hz/msn) in cirrhotic patients and 19.09 ± 4.16 (Hz/msn) in healthy subjects (p < 0.001). We found a positive statistical significance between PAS and systolic pulmonary arterial pressure (sPAP) (r = 0.378; p = 0.001). PAS was an independent predictor that was associated with cirrhosis disease according to multivariate logistic regression analysis (OR: 1.209; 95% CI: 1.059–1.381; p = 0.005). Conclusion Based on the study results, we consider that PAS may help in the early detection of changes in the pulmonary vascular bed, even if the RV function parameters or sPAP are within the normal range.
