Abstract
Ezetimibe has been reported to provide significant incremental reduction in low-density-lipoprotein cholesterol (LDL-C) when added to a statin; however, its effect on coronary atherosclerosis has not yet been evaluated in detail. The aim of this study was to investigate the add-on effect of ezetimibe to a statin on coronary atherosclerosis evaluated by intravascular ultrasound (IVUS).In this prospective randomized open-label study, a total of 51 patients with stable coronary artery disease (CAD) requiring percutaneous coronary intervention (PCI) were enrolled, and assigned to a combination group (n = 26, rosuvastatin 5 mg/day + ezetimibe 10 mg/day) or a monotherapy group (n = 25, rosuvastatin 5 mg/day). Volumetric IVUS analyses were performed at baseline and 6 months after the treatment for a non-PCI site. LDL-C level was significantly reduced in the combination group (-55.8%) versus that in the monotherapy group (-36.8%; P = 0.004). The percent change in plaque volume (PV), the primary endpoint, appeared to decrease more effectively in the combination group compared with the monotherapy group (-13.2% versus -3.1%, respectively, P = 0.050). Moreover, there was a significant group × time interaction in the effects of the two treatments on PV (P = 0.021), indicating the regressive effect of the combination therapy on PV was greater than that of monotherapy for subtly different values of baseline PV in the two treatment groups. Moreover, percent change in PV showed positive correlations with percent change of LDL-C (r = 0.384, P = 0.015).Intensive lipid-lowering therapy with ezetimibe added to usual-dose statin may provide significant incremental reduction in coronary plaques compared with usual-dose statin monotherapy.

Abstract
The effects of combining angiotensin-receptor blockers of different peroxisome proliferator-activated receptor γ-activating capacity with rosuvastatin on high-density lipoprotein (HDL) subfractions and associated enzymes in patients with mixed dyslipidemia, hypertension, and prediabetes were assessed. Patients (n = 151) were randomly allocated to rosuvastatin (10 mg/d) plus telmisartan 80 mg/d (RT group, n = 52) or irbesartan 300 mg/d (RI group, n = 48) or olmesartan 20 mg/d (RO group, n = 51). Total and intermediate HDL cholesterol (HDL-C) levels did not change in any group. Large HDL-C increased, while small HDL-C decreased significantly in all the groups (P = not significant between the groups). The mass of HDL lipoprotein-associated phospholipase A2 (HDL-Lp-PLA2) and the activities of paraoxonase 1 remained unchanged in all the groups. However, HDL-Lp-PLA2 activity increased only in the RT group (+21.4%; P < .01 vs baseline) and did not change in the RI (-4.3%; P = .005 vs RT group) and RO (+3.2%; P = .01 vs RT) groups. In conclusion, only the combination of rosuvastatin with telmisartan increased the possibly antiatherosclerotic HDL-Lp-PLA2 activity.

Abstract
We compared the effects of lipid lowering with rosuvastatin (RSV) monotherapy versus intensified treatment by combining RSV with ezetimibe (EZT) on kidney function in patients undergoing vascular surgery. Patients were randomly assigned to either 10 mg/d RSV (n = 136) or RSV 10 mg/d plus EZT 10 mg/d (RSV/EZT, n = 126). At 12 months, a similar decrease in estimated glomerular filtration rate (eGFR) was noted. Patients who achieved a low-density lipoprotein cholesterol (LDL-C) of <100 mg/dL had less eGFR decrease than those patients having an LDL-C limit of more than 100 mg/dL. There were no significant changes in the urinary total protein to creatinine ratio in either group. Significant microalbuminuria was evident in both the groups. Patients undergoing vascular surgery show deterioration in their renal function during the first year, despite statin therapy. Intensified lipid-lowering therapy by adding EZT does not appear to have any renoprotective effect.

Abstract
BACKGROUND Little is known about the differences between standard-dose statins effects on glucose level and lipids in Japanese patients with diabetes mellitus (DM). METHODS AND RESULTS The 1,049 patients were randomly assigned to either the rosuvastatin group or atorvastatin group. There were no significant differences between the 2 groups in the effect on non-high-density lipoprotein cholesterol (non-HDL-C) and HbA1c at 12 months. However, physicians tended to switch to more intensive therapy for DM in the atorvastatin group. CONCLUSIONS Rosuvastatin 5 mg and atorvastatin 10 mg have a similar lowering effect on non-HDL-C, but might be different in terms of adverse effect on glucose levels.

Abstract
Several randomized studies have suggested that pretreatment with statins may reduce a periprocedural biomarker release in patients who underwent percutaneous coronary intervention (PCI); however, results remain controversial. The purpose of this study was to investigate the effect of a 1-day rosuvastatin therapy on troponin I release in patients who underwent nonemergency PCI. A total of 445 patients with angina pectoris were randomly assigned to therapy with rosuvastatin (20 mg 12 hours before coronary angiography + 20 mg immediately before PCI; rosuvastatin group, 220 patients) or PCI without statin therapy (control group, 225 patients). In patients taking statins (73%), rosuvastatin was added to their long-term statin therapy. The primary end point was the incidence of TnI microleak defined as TnI elevation >1.5× upper limit of normal, and the secondary end point was the incidence of post-PCI TnI elevation >3× upper limit of normal. The incidence of primary and secondary end point in the rosuvastatin versus control group was 13.6% versus 12% (p = 0.61) and 8.2% versus 7.1% (p = 0.67), respectively. Patients with C-reactive protein ≥2.0 mg/L had a decreased release of post-PCI TnI in the rosuvastatin group (0.032 [0.010 to 0.143] μg/L vs 0.056 [0.018 to 0.241] μg/L; p = 0.04). In conclusion, 1-day rosuvastatin therapy (20 mg twice a day) did not influence post-PCI TnI release in patients with angina. However, these results suggest that, in patients with an advanced inflammatory status, rosuvastatin loading therapy might have a cardioprotective effect.

Abstract
OBJECTIVE This study was carried out to examine the difference in effects between rosuvastatin and pravastatin on neointimal formation after the placement of a drug-eluting stent (DES). MATERIALS AND METHODS Forty patients who underwent placement of a DES in our hospital were prospectively randomized to receive rosuvastatin (n=20) or pravastatin (n=20), and analyzed by optical coherence tomography at the chronic stage. The main outcome measure was comparison of neointimal coverage analyzed at a strut level. RESULTS A significant reduction in total cholesterol, low-density lipoprotein, and white blood cell count was observed during the study in the rosuvastatin group (total cholesterol, from 4.82±0.90 to 4.43±0.77 mmol/l, P=0.038; low-density lipoprotein, from 2.85±0.76 to 2.34±0.57 mmol/l, P=0.006; white blood cell count, from 5810±1399 to 5355±1257/µl, P=0.048), but not in the pravastatin group. Although not statistically significant, C-reactive protein was lower in the rosuvastatin than in the pravastatin group at the chronic stage (1.14±1.21 vs. 7.67±13.67 mg/l, P=0.051). Malapposed and uncovered struts were significantly less frequent in the rosuvastatin group than in the pravastatin group (malapposed, 0.06 vs. 0.60%, P<0.001; uncovered, 6.49 vs. 11.29%, P<0.001). The difference in uncovered struts was maintained even when stent types were analyzed separately (everolimus-eluting stent, 4.81 vs. 6.21%, P=0.007; sirolimus-eluting stent, 14.40 vs. 20.86%, P<0.001). Comparison of neointimal thickness between the rosuvastatin and the pravastatin groups showed inconsistent results depending on the stent types analyzed. CONCLUSION Compared with pravastatin, the use of rosuvastatin resulted in lower frequency of uncovered and malapposed struts after the placement of a DES, which might be mediated through improved inflammatory and lipid profiles.

Abstract
OBJECTIVES We prospectively compared the preventive effects of rosuvastatin and atorvastatin on contrast-induced nephropathy (CIN) in patients with chronic kidney disease (CKD) undergoing percutaneous coronary intervention (PCI). METHODS We enrolled 1078 consecutive patients with CKD undergoing elective PCI. Patients in Group 1 (n = 273) received rosuvastatin (10 mg), and those in group 2 (n = 805) received atorvastatin (20 mg). The primary end-point was the development of CIN, defined as an absolute increase in serum creatinine ≥0.5 mg/dL, or an increase ≥25% from baseline within 48-72 h after contrast medium exposure. RESULTS CIN was observed in 58 (5.4%) patients. The incidence of CIN was similar in patients pretreated with either rosuvastatin or atorvastatin (5.9% vs. 5.2%, p = 0.684). The same results were also observed when using other definitions of CIN. Clinical and procedural characteristics did not show significant differences between the two groups (p>0.05). Additionally, there were no significant inter-group differences with respect to in-hospital mortality rates (0.4% vs. 1.5%, p = 0.141), or other in-hospital complications. Multivariate logistic regression analysis revealed that rosuvastatin and atorvastatin demonstrated similar efficacies for preventing CIN, after adjusting for potential confounding risk factors (odds ratio = 1.17, 95% confidence interval, 0.62-2.20, p = 0.623). A Kaplan-Meier survival analysis showed that patients taking either rosuvastatin or atorvastatin had similar incidences of all-cause mortality (9.4% vs. 7.1%, respectively; p = 0.290) and major adverse cardiovascular events (29.32% vs. 23.14%, respectively; p = 0.135) during follow-up. CONCLUSIONS Rosuvastatin and atorvastatin have similar efficacies for preventing CIN in patients with CKD undergoing PCI.

Abstract
AIMS: Rosuvastatin and pitavastatin have been proposed as probe substrates for the organic anion-transporting polypeptide (OATP) 1B, but clinical data on their relative sensitivity and selectivity to OATP1B inhibitors are lacking. A clinical study was therefore conducted to determine their relative suitability as OATP1B probes using single oral (PO) and intravenous (IV) doses of the OATP1B inhibitor rifampicin, accompanied by a comprehensive in vitro assessment of rifampicin inhibitory potential on statin transporters. METHODS The clinical study comprised of two separate panels of eight healthy subjects. In each panel, subjects were randomized to receive a single oral dose of rosuvastatin (5 mg) or pitavastatin (1 mg) administered alone, concomitantly with rifampicin (600 mg) PO or IV. The in vitro transporter studies were performed using hepatocytes and recombinant expression systems. RESULTS Rifampicin markedly increased exposures of both statins, with greater differential increases after PO vs. IV rifampicin only for rosuvastatin. The magnitudes of the increases in area under the plasma concentration-time curve were 5.7- and 7.6-fold for pitavastatin and 4.4- and 3.3-fold for rosuvastatin, after PO and IV rifampicin, respectively. In vitro studies showed that rifampicin was an inhibitor of OATP1B1 and OATP1B3, breast cancer resistance protein and multidrug resistance protein 2, but not of organic anion transporter 3. CONCLUSIONS The results indicate that pitavastatin is a more sensitive and selective and thus preferred clinical OATP1B probe substrate than rosuvastatin, and that a single IV dose of rifampicin is a more selective OATP1B inhibitor than a PO dose.

Journal of atherosclerosis and thrombosis. 2014;(12):1298-307
Abstract
AIM: We used quantitative coronary angiography (QCA) to investigate whether coronary plaque progression can be inhibited by controlling lipids with rosuvastatin at Japanese standard doses following elective percutaneous coronary intervention (PCI). METHODS A total of 143 patients who underwent elective PCI were randomized to either the rosuvastatin (5 or 2.5mg/day) or non-statin group. Changes from baseline in the minimal lumen diameter (MLD) and average lumen diameter (ALD) measured using QCA were analyzed in both target and non-target lesions. RESULTS The changes in MLD and ALD from baseline to 24 months in the non-target lesions were significantly smaller in the rosuvastatin group than in the non-statin group (-0.079 ± 0.014 mm vs.-0.135 ± 0.019 mm, p=0.022; -0.062 ± 0.012 mmvs. -0.109 ± 0.016mm, p=0.025). The changes in MLD from six to 24 months in the target lesions were significantly lower in the rosuvastatin group than in the non-statin group among the patients treated with drug-eluting stents (-0.046 ± 0.108 mm vs. -0.133 ± 0.108 mm, p=0.009) versus those treated with bare-metal stents (-0.011 ± 0.094 mm vs. -0.015 ± 0.040 mm, p=0.255). CONCLUSIONS The present study demonstrated that the administration of a standard dose of rosuvastatin slows coronary plaque progression and may prevent the late catch-up phenomenon associated with drug-eluting stents in patients who undergo elective PCI.

Abstract
Elevated plasma levels of asymmetric dimethylarginine (ADMA) are prevalent in patients with hypercholesterolemia and coronary artery disease. A total of 83 patients with hypercholesterolemia and angiographically documented mild coronary artery stenosis were randomized to rosuvastatin treatment (20 mg) or atorvastatin treatment (40 mg) once daily for 6 weeks after a 4-week dietary lead-in phase. Both statins decreased total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglyceride levels effectively. Only rosuvastatin increased high-density lipoprotein cholesterol (HDL-C) levels. Both rosuvastatin and atorvastatin decreased plasma ADMA levels; rosuvastatin had a significantly greater effect. The reduction in ADMA levels were correlated with the reduction in TC and LDL-C levels as well as LDL-C-HDL-C ratio. Treatment with rosuvastatin or atorvastatin in patients with hyperlipidemia with mild coronary artery stenosis may lead to a decrease in ADMA levels, which may contribute to improved endothelial function.
