Lipid profiles reflecting high and low risk for coronary heart disease: contribution of apolipoprotein E polymorphism and lifestyle
Abstract
To elucidate the role of modifiable factors and the apolipoprotein E polymorphism in explaining lipid profiles reflecting low, average and high risk for coronary heart disease, we selected subjects from a large population-based study. Subjects with low total cholesterol (TC) (< 15th percentile) and high HDL-cholesterol levels (> 85th percentile) were randomly selected (n = 99) and represent subjects with a low risk lipid profile. Additionally, 95 subjects with total and HDL-cholesterol levels in the 15% around the population-median (median risk lipid profile) and 100 subjects with high TC (> 85th percentile) and low HDL-cholesterol levels (< 15th percentile) (high risk lipid profile) were selected. Compared with E3/3 subjects, the likelihood for a low risk lipid profile was considerably higher (odds ratio 14.3; 2.6-79) in female, but not in male E2-carriers (1.5; 0.3-6.7). Smoking and alcohol consumption were independently associated with a low risk lipid profile in both genders, physical inactivity only in women. The odds ratio for a high risk lipid profile was elevated in male E4-carriers (4.9; 1.1-23) only. In addition to the E4 isoform, smoking and physical inactivity, overweight was the main determinant for a high risk lip...Continue Reading

ApoE Phenotypes
Apolipoprotein E (APOE) is a protein involved in fat metabolism and associated with the pathogenesis of Alzheimer's disease and cardiovascular disease. Here is the latest research on APOE phenotypes.
ApoE, Lipids & Cholesterol
Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
