Lp(alpha) lipoprotein and pre-beta1-lipoprotein in relation to lipid levels in males.
Previous studies have shown that a slow-moving pre-beta-lipoprotein fraction, named the pre-beta1-lipoprotein, occurred significantly more frequently among subjects with coronary heart disease (CHD) than among healthy individuals. This lipoprotein is closely related to, and probably identical with, the Lp(a) lipoprotein. Immunological tests likewise showed that Lp(a) lipoprotein was significantly more common among patients with CHD than among controls. Mean cholesterol and triglyceride levels were higher in pre-beta1-lipoprotein positive than in pre-beta1-lipoprotein negative individuals. Lp(a+) individuals tended to have higher serum cholesterol values than did Lp(a-) persons but there was no difference in the mean triglyceride value. This apparent discrepancy seems to be due to the presence in occasional sera of lipoprotein fractions with pre-beta1-mobility, usually of a VLDL nature. These lipoproteins are not associated with the Lp(a) lipoprotein.
