Plasma lipids are major risk factors for coronary heart disease (CHD). Cholesteryl ester transfer protein (CETP) and apolipoprotein (apo) E genes are involved in lipoprotein metabolism, thus affecting plasma lipid and lipoproteins levels. Furthermore, such polymorphisms have been associated with susceptibility to CHD and obesity. We evaluated the influence of the gene polymorphisms of CETP TaqIB (B1, B2) and I405V (V, I) and apo E (∊2,∊3,∊4) on lipid levels, according to body mass index (BMI) in Greek men with CHD. The TaqIB (B1, B2) polymorphism affected plasma low-density lipoprotein cholesterol levels in overweight men with CHD, whereas the I405V (V, I) polymorphism affected triglyceride concentrations in normal weight men. No correlation was found between BMI and apo E polymorphisms. Large prospective studies are required to investigate the relationships of CETP and apo E polymorphisms with lipids, BMI, and CHD susceptibility.
