In comparisons among these peptides, the AUC values for high-molecular weight adiponectin and the high-molecular weight adiponectin/total adiponectin ratio were similar to that of heregulin-β1 but inferior to that of salusin-α Therefore, serum salusin-α level has higher diagnostic value in detecting CAD compared with the other three peptides. This evidence concerns the gene ADIPOQ and coronary artery disorder.
