Abstract:
Objective To investigate the correlation of IL-6-572GC mutation with the incidence and severity of CHD in the Han elderly in Henan Province.Methods A total of 446 elderly CHD pa-tients of Han majority in Henan Province who were admitted to Department of Cardiovascular Diseases of our hospital from January 2020 to December 2022 were enrolled as the study group,and 218 healthy elderly patients taking physical examination in the same period were selected as the control group.The genotypes of IL-6-174GC,IL-6-572GC and IL-6-597GA were detected in the two groups.Logistic regression analysis was used to analyze the relationship between IL-6-572G/C gene polymorphism and CHD in the elderly,as well as the correlation between IL-6-572GC genotype and the severity of CHD.Results Larger proportions of hypertension and diabetes and higher LDL-C level,but lower HDL-C level were observed in the study group than the control group(P＜0.05,P＜0.01).There were three genotypes at IL-6-174GC locus(GG,GC and CC),three genotypes at IL-6-572GC locus(GG,GC and CC),and three genotypes at IL-6-597GA locus(GG,GA and AA).There were no significant differences in the genotype fre-quencies of IL-6-174GC and IL-6-597GA between the two groups(P＞0.05),but there was a sig-nificant difference in the genotype frequency of IL-6-572GC(P＜0.01)and the genotype frequen-cy of GG was significantly lower in the study group than the control group(33.18％vs 46.82％,P＜0.01).Logistic regression analysis showed that IL-6-572GC(OR=1.534,95％CI:1.180-1.995),hypertension(OR=1.442,95％CI:1.033-1.957),diabetes(OR=1.610,95％CI:1.083-2.391),HDL-C(OR=0.467,95％CI:0.266-0.818)and LDL-C(OR=2.004,95％CI:1.104-3.636)were all influencing factors of CHD(P＜0.05,P＜0.01).At IL-6-572GC locus,the inci-dence of single branch lesions was higher in the carriers of GG genotype than those of GC and CC genotypes,and the incidence of 3-branch lesions was lower than that of CC genotype(P＜0.05).Conclusion The mutation of IL-6-572GC gene is correlated with the incidence and severity of CHD in the elderly Henan Han people,and its mutation also increases the risk and severity of the disease.
