Correlation and scatter plot of hydrogen sulfide (H₂S), synthase cystathionine-γ-lyase (CSE) mRNA and pulmonary vascular indexes on HRCT. (A) H₂S was negatively correlated with main pulmonary artery diameter (mPAD) (r = - 0.25, P < 0.05); (B) H₂S was negatively correlated with axial diagonal mPAD (r = - 0.27, P < 0.05); (C) H₂S was negatively correlated with sagittal mPAD (r = - 0.32, P < 0.01); (D) H₂S was negatively correlated with ascending aortic diameter (AAD) (r = - 0.30, P < 0.01); (E) Relative expression of CSE mRNA was positively correlated with coronal mPAD (r = 0.30, P < 0.05); (F) Relative expression of CSE mRNA was positively correlated with sagittal mPAD (r = 0.36, P < 0.05).
