Cells co‐expressing CD38 and CD45RO [11.5% ± 4.3% vs 9.7% ± 3.6%, P = 0.033], CD39 [53.8% ± 20.5% vs 43.2% ± 21.6%, P = 0.014], HLA‐DR [15.1% ± 7.1% vs 12.3% ± 6.7%, P = 0.049] and Ki67 [9.2% ± 4.2% vs 7.0% ± 2.9%, P = 0.007] were also significantly increased in the CAD+ group. This evidence concerns the gene CD38 and coronary artery disorder.
