Kawamura and co-workers [79] evaluated the chemokine receptor membrane expression (CCR2/CCR5/CXCR2/CXCR3) along with the plasma concentrations of CCL2 in 55 CAD patients who underwent percutaneous transluminal coronary angioplasty (PTCA) and 20 patients without a significant coronary stenosis according to the results of a coronary catheterization. This evidence concerns the gene CCL2 and coronary artery disorder.
