Abstract
We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the protective effects of rosuvastatin on contrast-induced acute kidney injury (CI-AKI) and major adverse cardiovascular events (MACEs) in patients undergoing cardiac catherization.PubMed, MEDLINE, Web of Science, EMBASE, ClinicalTrials.gov, and the Cochrane Central RCTs were searched for RCTs from inception to May 2015, to compare rosuvastatin for preventing CI-AKI with placebo treatment in patients undergoing cardiac catherization.Five RCTs with a total of 4045 patients involving 2020 patients pretreated with rosuvastatin and 2025 control patients were identified and analyzed. Patients treated with rosuvastatin had a 51% lower risk of CI-AKI compared with the control group based on a fixed-effect model (OR = 0.49, 95% CI = 0.37-0.66, P < 0.001), and showed a trend toward a reduced risk of MACEs (OR = 0.62, 95% CI = 0.36-1.07, P = 0.08). A subgroup analysis showed that studies with Jadad score ≥3 showed a significant reduction of CI-AKI (OR = 0.53, 95% CI, 0.38-0.73, P < 0.001). However, the risk of CI-AKI did not significantly differ in the studies with Jadad score <3 (OR = 0.54, 95% CI, 0.13-2.24, P = 0.40). In addition, the rosuvastatin treatment showed no effect for preventing CI-AKI in patients with chronic kidney disease (CKD) undergoing elective cardiac catherization (I = 0%, OR = 0.81, 95% CI = 0.41-1.61, P = 0.55).This updated meta-analysis demonstrated that preprocedural rosuvastatin treatment could significantly reduce the incidence of CI-AKI, with a trend toward a reduced risk of MACEs in patients undergoing cardiac catheterization. However, rosuvastatin treatment did not seem to be effective for preventing CI-AKI in CKD patients undergoing elective cardiac catheterization.

Abstract
BACKGROUND Rosuvastatin is one of the most potent statins and is currently widely prescribed. It is therefore important to know the dose-related magnitude of effect of rosuvastatin on blood lipids. OBJECTIVES Primary objective To quantify the effects of various doses of rosuvastatin on serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, non-HDL-cholesterol and triglycerides in participants with and without evidence of cardiovascular disease. Secondary objectives To quantify the variability of the effect of various doses of rosuvastatin.To quantify withdrawals due to adverse effects (WDAEs) in the randomized placebo-controlled trials. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) Issue 10 of 12, 2014 in The Cochrane Library, MEDLINE (1946 to October week 5 2014), EMBASE (1980 to 2014 week 44), Web of Science Core Collection (1970 to 5 November 2014) and BIOSIS Citation Index (1969 to 31 October 2014). No language restrictions were applied. SELECTION CRITERIA Randomized controlled and uncontrolled before-and-after trials evaluating the dose response of different fixed doses of rosuvastatin on blood lipids over a duration of three to 12 weeks. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility criteria for studies to be included and extracted data. WDAEs information was collected from the placebo-controlled trials. MAIN RESULTS One-hundred and eight trials (18 placebo-controlled and 90 before-and-after) evaluated the dose-related efficacy of rosuvastatin in 19,596 participants. Rosuvastatin 10 to 40 mg/day caused LDL-cholesterol decreases of 46% to 55%, when all the trials were combined using the generic inverse variance method. The quality of evidence for these effects is high. Log dose-response data over doses of 1 to 80 mg, revealed strong linear dose-related effects on blood total cholesterol, LDL-cholesterol and non-HDL-cholesterol. When compared to atorvastatin, rosuvastatin was about three-fold more potent at reducing LDL-cholesterol. There was no dose-related effect of rosuvastatin on blood HDL-cholesterol, but overall, rosuvastatin increased HDL by 7%. There is a high risk of bias for the trials in this review, which would affect WDAEs, but unlikely to affect the lipid measurements. WDAEs were not statistically different between rosuvastatin and placebo in 10 of 18 of these short-term trials (risk ratio 0.84; 95% confidence interval 0.48 to 1.47). AUTHORS' CONCLUSIONS The total blood total cholesterol, LDL-cholesterol and non-HDL-cholesterol-lowering effect of rosuvastatin was linearly dependent on dose. Rosuvastatin log dose-response data were linear over the commonly prescribed dose range. Based on an informal comparison with atorvastatin, this represents a three-fold greater potency. This review did not provide a good estimate of the incidence of harms associated with rosuvastatin because of the short duration of the trials and the lack of reporting of adverse effects in 44% of the placebo-controlled trials.

Clinical utility of rosuvastatin and other statins for cardiovascular risk reduction among the elderly.
Long, SB, Blaha, MJ, Blumenthal, RS, Michos, ED
Clinical interventions in aging. 2011;:27-35
Abstract
Age is one of the strongest predictors of cardiovascular disease (CVD) risk. Treatment with statins can significantly reduce CVD events and mortality in both primary and secondary prevention. Yet despite the high CVD risk among the elderly, there is underutilization of statins in this population (ie, the treatment-risk paradox). Few studies have investigated the use of statins in the elderly, particularly for primary prevention and, as a result, guidelines for treating the elderly are limited. This is likely due to: uncertainties of risk assessment in older individuals where the predictive value of individual risk factors is decreased; the need to balance the benefits of primary prevention with the risks of polypharmacy, health care costs, and adverse medication effects in a population with decreased life expectancy; the complexity of treating patients with many other comorbidities; and increasingly difficult social and economic concerns. As life expectancy increases and the total elderly population grows, these issues become increasingly important. JUPITER (Justification for the Use of statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) is the largest primary prevention statin trial to date and enrolled a substantial number of elderly adults. Among the 5695 JUPITER participants ≥ 70 years of age, the absolute CVD risk reduction associated with rosuvastatin was actually greater than for younger participants. The implications of this JUPITER subanalysis and the broader role of statins among older adults is the subject of this review.

Should we measure C-reactive protein on earth or just on JUPITER?
Bajpai, A, Goyal, A, Sperling, L
Clinical cardiology. 2010;(4):190-8
Abstract
Evidence for the role of inflammation in the pathogenesis of atherosclerosis is compelling and has generated interest in high-sensitivity C-reactive protein (hs-CRP) as a marker of cardiovascular risk. Data regarding hs-CRP and cardiovascular risk, though largely consistent, is of unclear clinical relevance. Most recently, the Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin (JUPITER) trial has led to further debate regarding the utility of hs-CRP. This article provides a comprehensive review of the data regarding cardiovascular risk and hs-CRP with an emphasis on the JUPITER trial and concludes with an evidence-based analysis of the current role of hs-CRP in cardiovascular risk assessment.

The JUPITER and AURORA clinical trials for rosuvastatin in special primary prevention populations: perspectives, outcomes, and consequences.
Narla, V, Blaha, MJ, Blumenthal, RS, Michos, ED
Vascular health and risk management. 2009;:1033-42
Abstract
Statins have emerged at the forefront of preventive cardiology and have significantly reduced cardiovascular events and mortality. Nonetheless, cardiovascular disease remains the leading cause of death in the United States and in other developed countries, as well as the etiology of significant morbidity and health-care expenditure. In an attempt to reduce potentially missed opportunities for instituting preventive therapy, the JUPITER study (Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) and the AURORA study (A Study to Evaluate the Use of Rosuvastatin in Subjects on Regular Hemodialysis: An Assessment of Survival and Cardiovascular Events) examined the effect of statins in two specific patient populations who currently do not meet the guidelines for statin treatment, but nonetheless, are at high cardiovascular risk. This review outlines the JUPITER and AURORA trials, interprets the data and significance of the results, analyses the drawbacks and impact of both trials and delineates the potential for further clinical trials.

Coronary atherosclerosis can regress with very intensive statin therapy.
Sipahi, I, Nicholls, SJ, Tuzcu, EM, Nissen, SE
Cleveland Clinic journal of medicine. 2006;(10):937-44
Abstract
The ASTEROID trial (JAMA 2006; 295:1556-1565) showed that very intensive statin therapy with rosuvastatin 40 mg once daily results in highly significant regression of coronary atherosclerosis as assessed by serial intravascular ultrasonography (IVUS). The mean low-density lipoprotein cholesterol (LDL-C) level achieved with this regimen was 61 mg/dL, and the mean high-density lipoprotein cholesterol (HDL-C) level increased by 15%. While the merits of concomitant LDL-C-lowering and HDL-C-raising therapies remain to be determined, the results of the ASTEROID and other recent trials suggest that the optimal strategy for lipid-lowering in patients with coronary artery disease is to try for the lowest LDL-C level that can be attained without adverse effects.

Abstract
BACKGROUND The risk of cardiovascular complications is markedly increased in patients on dialysis treatment. This includes cardiac disease, stroke, and peripheral vascular disease. The mortality in dialysis patients is markedly higher compared to a nonuremic population. There are several cardiovascular (CV) risk factors that are unique to this population, one of which is dyslipidemia. Uremic patients do not usually develop hypercholesterolemia, but rather are characterized by high levels of very low density lipoprotein (VLDL) triglycerides, low high density lipoprotein (HDL) cholesterol, and elevated levels of modified low density lipoprotein (LDL) particles, which are particularly harmful to the vascular wall. HMG-CoA reductase inhibitors (statins) have been proven to be very efficient in reducing CV events in a nonrenal population. There are several landmark trials that have demonstrated that statins reduce the mortality in cardiovascular disease (CVD) in populations with normal, or close to normal, renal function. There are some observational registry data indicating that this may also be true in hemodialysis (HD) patients, but no prospective controlled trial has been performed to date. METHODS We present the rationale for, and a brief outline of, a randomized placebo-controlled trial using a novel drug, rosuvastatin, in HD patients, to target cardiovascular events (the AURORA study). This study will include close to 3000 male and female HD patients, aged 50-80 years. The study is event driven and it has been estimated that it will run for a follow-up time close to four years. CONCLUSION There is a sound rationale for making a randomized placebo-controlled statin trial in HD patients, with the objective to demonstrate an effect on CV mortality and morbidity.
