We investigated the lipid lowering and anti-atherosclerotic effects of atorvastatin in patients with hypercholesterolemia. Thirty patients were given atorvastatin 10 mg daily, and assessed for serum lipids, intima-media thickness (IMT), and brachial-ankle pulse wave velocity (ba-PWV) at the baseline, 6 months, and 12 months. Remnant-like particle-cholesterol (RLP-C), lipoprotein (a)(Lp(a)), and high-sensitivity C-reactive protein (hs-CRP) were measured in some patients at the baseline and at 6 months. Total cholesterol, triglyceride and low-density lipoprotein cholesterol were significantly decreased by 32%, 23% and 44% at 6 months, respectively, and these effects were sustained at 12 months. There was no change in high-density lipoprotein cholesterol. IMT at the baseline was 0.88 ± 0.16 mm and decreased to 0.76 ± 0.13 mm at 6 months, remaining at 0.75 ± 0.12 mm at 12 months. We did not observe any significant changes in ba-PWV. RLP-C and hs-CRP were significantly reduced from 7.3 ± 10.8 mg/dL to 4.3 ± 5.3 mg/dL and 0.075 ± 0.065 mg/dL to 0.039 ± 0.043 mg/dL at 6 months, respectively. There was no change in Lp(a). The observed decrease in IMT suggests that atorvastatin possibly improves atherosclerosis, in addition to the significant reduction of serum lipids.
