Patients without CAD displayed the highest platelet surface–associated levels of CXCL14, followed by patients with ACS and those with CCS, showing the lowest platelet CXCL14 levels (mean mean fluorescence intensity logarithmized, 1.51 ± 0.40 vs 1.47 ± 0.38 vs 1.35 ± 0.35, respectively) (P for other vs ACS, 1; other vs CCS, .012; and ACS vs CCS, .008, respectively). Here, CXCL14 is linked to coronary artery disorder.
