In total, 86 CAD patients were divided into the single-, double-, and triple-vessel disease groups according to the angiographic results and there were no differences in the frequencies of CD4+LAP+ T cells, CD4+CD25−LAP+ T cells, CD4+CD25+ T cells, and CD4+CD25+LAP− T cells among the three groups (see Table 2). Here, CD4 is linked to coronary artery disorder.
