The levels of SPAP and mPAP in the PAH-CHD-H group were significantly higher than those of the PAH-CHD-M and PAH-CHD-L groups (p < 0.05), but there was no statistically significant difference in SPAP between the PAH-CHD-M and PAH-CHD-L groups (p > 0.05). This evidence concerns the gene PDZK1IP1 and coronary artery disorder.
