Abstract

The aim of this study was to explore the relationship between the ApoE gene polymorphism and dietary factors with stroke and circulating lipid levels in the Chinese population. We selected 580 patients with stroke and 580 age- and gender-matched healthy controls, and examined their ApoE polymorphism genotype using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. We also analyzed the relationship between the ApoE gene polymorphism and dietary factors as well as plasma lipid concentrations in this cohort. We detected six ApoE genotypes in the study populations, and determined that the E4 allele was positively associated with cerebral infarction (CI), whereas allele E2 was negatively associated with total cholesterol (TC) and low-density lipoprotein-cholesterol levels. The dietary habits of the subjects with descending order of average total TC and triglyceride levels were: subjects addicted to oily food > subjects addicted to sweets > subjects addicted to smoking > subjects addicted to alcohol > subjects following a vegetarian diet (P ApoE gene polymorphism was associated with a risk for CI in a Chinese population.
