Abstract

Little is known about the effects of statins on the quality of circulating low-density lipoprotein (LDL) in relation to atherosclerosis progression. In a double-blind, randomized trial of 325 patients with familial hypercholesterolemia (FH), we assessed the effects of high-dose atorvastatin (80 mg) and conventional-dose simvastatin (40 mg) on LDL subfraction profile (n = 289), LDL oxidizability (n = 121), and circulating autoantibodies to oxidized LDL (n = 220). Progression of atherosclerosis was measured by carotid intima media thickness (IMT) (n = 325). At baseline, the patients showed an intermediate LDL subfraction profile composed of three LDL subfractions (LDL1, LDL2, LDL3), with LDL2 as the predominant subfraction. A strong negative correlation was found between plasma triglycerides and the LDL subfraction profile (r = -.64, p = .000). Both plasma levels of triglycerides and small dense LDL3 correlated weakly with baseline IMT (r = .11, p = .04 and r = .15, p = .01, respectively; n = 289). No association was found between baseline IMT and oxidation parameters or circulating antibodies to oxidized LDL. Atorvastatin reduced triglycerides, LDL cholesterol, and all LDL subfractions to a greater extent than did simvastatin an...Continue Reading

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.
