|Title:||Apolipoproteins AI, B, and E polymorphisms in severe aortic valve stenosis|
|Abstract:||Hypercholesterolemia has been related to aortic valve stenosis (AS). Polymorphisms of apolipoproteins (apo) AI, B, and E are associated with variable levels of plasma lipids, but the association between these polymorphisms and AS is unknown. In a case-control study of groups matched by age, sex, comparable body mass index, hypertension, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol, we analyzed the distribution of apo AI A/G mutation, apo B signal peptide insertion/deletion, apo B XbaI restriction fragment length, and apo E polymorphisms in 62 non-diabetic patients with severe aortic valve stenosis and 62 control subjects. All patients underwent echocardiographic analysis. Univariate analysis showed a higher prevalence of the XbaI X + /X + genotype (p = 0.007) of apo B and the apo E2 allele (p = 0.034) in patients with severe AS. Apo polymorphisms were not associated with lipid levels, left ventricular mass, or the aortic gradient.|
