Interestingly, the CAD-positive patients demonstrated higher plasma concentrations of CXCL10 in the aorta as well as significantly higher transcoronary concentration gradients of circulating CXCL10 whereas no significant differences ofCCL2, CCL5 or hsCRP were observed in the aortic plasma concentrations or transcoronary concentration gradients between the CAD-positive and -negative groups. Here, CXCL10 is linked to coronary artery disorder.
