For patients with CHD in relation to CTEPH, we also noted eight common correlations, namely CD45+ and CD8+ (positive); CD8+ and CD3+ (positive); mPAP and RVSP (positive); CD4+ and CD4+/CD8+ (positive); mPAP and PASP (positive); PASP and RVSP (positive); mPAP and lymphocytes, which was positive for CHD and negative for CTEPH; and PASP and lymphocytes, for which we recorded identical differences to those noted above. This evidence concerns the gene CD8A and coronary artery disorder.
