Abstract
Background:Quality and quantity of high-density lipoprotein cholesterol (HDL-C) may be associated with cardiovascular risk. We investigated the effect of rosuvastatin on cholesterol efflux (CE) for HDL function and vascular health.
Methods and Results:We enrolled 30 dyslipidemic patients with type 2 diabetes mellitus and 20 healthy subjects as controls. Vascular health was assessed on flow-medicated dilation (FMD), nitroglycerin-induced dilatation of the brachial artery and carotid artery intima-media thickness (cIMT). These parameters were compared between patients and controls, and between baseline and at 12 weeks of treatment with rosuvastatin 20 mg. Age and body mass index were 49.8±11.3 years and 25.8±3.7 kg/m2in the patients, and 28.8±3.2 years and 22.4±2.4 kg/m2in the controls, respectively. The biomarkers related to lipid and glucose metabolism and lipoprotein (a), high-sensitivity C-reactive protein, and cIMT were significantly higher, and CE and FMD were significantly lower in the patients than in the controls. In the patients, rosuvastatin 20 mg decreased low-density lipoprotein cholesterol by 54.1% and increased HDL-C by 4.8%. The CE increased significantly after rosuvastatin treatment (12.26±2.72% vs. 14.05±4.14%). FMD also increased, and lipoprotein (a) and cIMT decreased significantly and were associated with changes of CE.
Conclusions:Rosuvastatin-induced changes in HDL function are significantly associated with cardiovascular benefit.
