Abstract
Lipoprotein mass concentrations were measured by analytical ultracentrifugation in a subset of 57 hypercholesterolaemic male participants in the National Heart, Lung, and Blood Institute Type II Coronary Intervention Study. 2-year changes in levels of intermediate-density lipoproteins (IDL) of flotation rate 12-20 were strongly predictive of progression of coronary artery disease at 5 years. Changes in serum mass concentrations of low-density lipoproteins (LDL; flotation rate 0-12), very-low-density lipoproteins (VLDL; flotation rate 20-400), high-density lipoproteins (HDL), and the HDL2 and HDL3 subfractions did not differ significantly between men with and without definite progression of coronary artery disease. The relation of IDL mass to disease progression remained significant (p less than 0.05) after adjustment for group assignment to cholestyramine treatment or placebo and was only slightly reduced (p less than or equal to 0.06) by adjustment for changes in LDL mass concentrations. Changes in IDL mass and ratios of HDL-cholesterol to total-cholesterol or LDL-cholesterol were inversely correlated and had a similar ability to predict progression. The findings are consistent with earlier evidence that IDL are directly involved in the development of coronary artery disease and suggest that ratios of HDL-cholesterol to total-cholesterol or LDL-cholesterol may be indicators of coronary disease risk partly owing to relations with IDL metabolism.This publication has 20 references indexed in Scilit:
