Comparisons with similar studies might involve investigations into other receptor genes, such as PROK2 (Lichtenauer and Jung, 2018), EDN1 (Liang et al., 2018), and NOS3 (Teralı and Ergören, 2019), which play roles in vascular function and inflammation regulation and may have similar implications in CAD. This evidence concerns the gene NOS3 and coronary artery disorder.
