In our study, we found that the serum resistin level was significantly higher (P-value=0.0) in the stable angina (8.368 ± 1.633 ng/ml) and acute myocardial infarction (13.606 ± 2.067 ng/ml) groups (P-value=0.0) than the control group (2.4272±1.25210 ng/ml). This evidence concerns the gene RETN and myocardial infarction.
