When the groups were compared in terms of laboratory findings, the following values were higher in the critical CAD group compared with the non-critical CAD group; glucose levels (p < 0.001), neutrophil counts (p < 0.001), CRP levels (p < 0.001), NLR (p < 0.001), PLR (p < 0.001), and GLR (p < 0.001). Here, CRP is linked to coronary artery disorder.
