Abstract
OBJECTIVE: To investigate the correlation between growth differentiation factor 15 (GDF 15) + 157 A/T polymorphism and the formation of collateral circulation in acute non-ST segment elevated myocardial infarction in Han population of Shandong province. METHOD: The medical records of 200 cases of patients undergoing selective coronary angiography were analyzed, and the arterial blood specimens of included patients were collected before coronary angiography. Based on the results of coronary angiography, patients were divided into acute myocardial infarction (AMI) group and normal control group; AMI group was divided into collateral group and non-collateral group by Rentrop's grading method; polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing methods were used to analyze the GDF 15 + 157 A/T polymorphism in the two groups. RESULTS: There were statistically significant differences in GDF 15 + 157 A/T AA and AT distribution between AMI group and the control group (P = 0.002); and there was statistically significant difference in allele frequencies between the two groups (P = 0.006); for AMI group, there were statistically significant differences in GDFAA and AT genotype distribution between patients with and without collateral (P = 0.014), and there was statistically significant difference in allele frequencies between the two (P = 0.025). CONCLUSION: There was correlation between GDF 15 + 157 A/T polymorphism and the formation of collateral circulation in patients with non-ST-segment elevated myocardial infarction.
