ACE I/D polymorphisms were assessed using PCR, and their frequency was determined. <br />Results: There were 298 people, 95 CAD patients, and 203 controls, with an average age of 50.96±3.45 and 51.14±10.20. We discovered that the frequency of the D allele was significantly higher in CAD patients than in controls (P = 0.0009). In contrast, the frequency of the I allele was significantly higher in controls than in CAD patients (P = 0.0009). The D allele carriers genotypes (DD + ID) were more frequent in the CAD patients than in the control group (P = 0.008). The ACE II genotype-state carriers were more common in the control group than in CAD patients (P = 0.008). However, in the case of the ACE ID genotype, no significant differences were not found in the tested groups (P = 0.47).<br /><br />Conclusions: These findings suggest that individuals with the ACE DD genotype are predisposed to CAD, whereas individuals with the ACE II genotype state are protected. https://arya.mui.ac.ir/article_26240_82afe738e1cd207f17505cc80d19b0b8.pdf
