In the present study the investigators are researching the effects of the cholesterol absorption inhibitor ezetimibe on postprandial lipemia and postprandial endothelial function in patients with the metabolic syndrome. The lipid-lowering effect of high-dose statin monotherapy on fasting lipids is equal to the combination therapy of low-dose statin and ezetimibe.
