The relationship between ApoE gene polymorphism and the efficacy of statins controlling hyperlipidemia

Objective: To explore the relationship between ApoE gene polymorphism and clinical efficacy of statins on lipidemia. Methods: Peripheral venous blood was obtained from 220 patients with hyperlipidemia who were admitted to the outpatient department of our hospital. The potential relationship between ApoE gene polymorphism and clinical effect of statins was analyzed. Results: In the three isomers (E2, E3, E4) of ApoE, expression level of ApoE protein in ApoE4 gene carriers was significantly different from that in E2 or E3 gene carriers (both P<0.05). At the same time, both the decrease rate of total cholesterol (TC) in blood lipid and low density lipoprotein cholesterol (LDL-C) and the rise rate of high density lipoprotein cholesterol (HDL-C) in ApoE4 carriers after taking statins were much lower than those in non-ApoE4 patients (P<0.05). Conclusion: ApoE gene polymorphism is associated with hyperlipidemia and has certain influence on the clinical efficacy of statins in treatment of hyperlipidemia.

Automated summary

The study found a relationship between ApoE gene polymorphism and the clinical efficacy of statins on patients with hyperlipidemia. Carriers of ApoE4 gene had lower changes in lipid levels after taking statins compared to non-ApoE4 patients.
