Unlabelled:
Recently, it has been reported that circulating oxidized low-density lipoprotein (Ox-LDL) might be a pivotal indicator for coronary artery disease and the severity of acute coronary syndromes. The purpose of this study was to investigate the effects of statins on Ox-LDL in patients with hypercholesterolemia. Sixteen patients with hypercholesterolemia were randomly assigned to 2 groups, one received 10 mg of pravastatin (n = 8) and the other received 20 mg of fluvastatin (n = 8). The plasma level of Ox-LDL was measured using a newly developed sandwich enzyme-linked immunosorbent assay (ELISA) method. There were no differences between the two groups in Ox-LDL, total cholesterol (TC), or LDL cholesterol (LDL-C) at the baseline. The reduction in Ox-LDL in the fluvastatin group was significantly higher than that in the pravastatin group (47.5% versus 25.2%, P = 0.033). The reductions in TC and LDL-C did not differ between the two groups.
Conclusion:
The present study has shown for the first time that the level of circulating Ox-LDL was significantly decreased by treatment with statins. In addition, the lowering effect of statins on the circulating Ox-LDL was independent of their lipid-lowering effect. Fluvastatin was more effective than pravastatin with regard to decreasing the circulating Ox-LDL.
