The Effects of Low Concentrations of Pravastatin on Placental Cells. Reprod Sci 2024; 31:3139-3147.

Abstract
Pravastatin is a promising medication to treat preeclampsia. However, the appropriate dose of pravastatin for managing preeclampsia has not been established. In this in vitro study, we examined the effects of low concentrations of pravastatin (0.01 to 10 µM) under hypoxic conditions on two types of placental cells and found that pravastatin decreased sFlt-1 levels up to 34% in cytotrophoblast cells isolated from human term placentas. Furthermore, we showed that sFlt-1 levels in HTR-8/SVneo cells, a cell line derived from first trimester trophoblast cells, decreased after exposure to very low concentrations of pravastatin (0.01, 0.1 µM). We also examined the effects of pravastatin on uterine spiral artery remodeling-related events and showed in wound healing and tube formation assays that low concentrations of pravastatin upregulated cell migration and invasion in HTR-8/SVneo cells. These results demonstrated that a low dose of pravastatin has in vitro effects that suggest a potential for anti-preeclamptic effects in vivo.

The combination of high uric acid and high C-reactive protein increased the risk of cardiovascular disease: A 15-year prospective cohort study. Nutr Metab Cardiovasc Dis 2024; 34:1508-1517. [PMID: 38503620 DOI: 10.1016/j.numecd.2024.01.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 09/23/2023] [Accepted: 01/24/2024] [Indexed: 03/21/2024]
Abstract
BACKGROUND AND AIMS Uric acid (UA) and C-reactive protein (CRP) may interact synergistically to accelerate the initiation and progression of cardiovascular disease (CVD). This study investigated the effects of a combination of high UA and high CRP on the risks of CVD. METHODS AND RESULTS A total of 90,270 participants recruited from the Kailuan study were included, who were divided into four groups according to the presence/absence of hyperuricemia and inflammation. Cox regression was applied to evaluate the hazard ratios (HRs) and 95% confidence intervals (95% CIs) of CVD. C-statistics, net classification index (NRI), and integrated discrimination improvement (IDI) were used to compare the incremental predictive of UA, CRP, and their combined effects on CVD. Mediation analysis was to explore the impact of CRP on the association between UA and CVD. Over a median follow-up of 14.95 years, we identified 11398 incident CVD cases. Compared to the low UA/low CRP group, the high UA/low CRP, low UA/high CRP and high UA/high CRP groups showed progressively higher risks of CVD, HR (95% CI): 1.18(1.10-1.27), 1.27(1.21-1.33) and 1.50 (1.33-1.69), respectively. The incorporation of UA and CRP into the traditional China-PAR model led to improvement in the C-statistic, NRI, and IDI, and was better than incorporation of either UA or CRP alone. Mediation analysis showed that CRP mediated the association between UA and CVD, accounting for 11.57% of the total effects. CONCLUSIONS High UA/high CRP is associated with increased risks of CVD. Incorporation of both UA and CRP provided additional value for risk stratification.

Abstract
Vascular diseases are the leading cause of death in Spain. Hypercholesterolemia is not only a cardiovascular risk factor, but also underlies the etiopathogenesis of atherosclerosis. Therefore, reducing LDL cholesterol (LDL-C) to the goals recommended by clinical practice guidelines, is essential to decrease the risk of vascular complications. Despite this, current LDL-C control is scarce, even in subjects with high and very high risk. This is mainly due to an insufficient intensification of lipid-lowering treatment. In this context, it is essential to prescribe the appropriate therapy, adjusted to patient's needs based on their LDL-C and their vascular risk. Rosuvastatin, alone or in combination with ezetimibe, provides intensive LDL-C reductions (up to 50-55% and 60-75%, respectively), with a low risk of side effects and in an efficient manner, in patients both without and with established atherosclerotic vascular disease.

PLoS One 2023; 18:e0295052. [PMID: 38039298 PMCID: PMC10691679 DOI: 10.1371/journal.pone.0295052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 11/15/2023] [Indexed: 12/03/2023] Open
Abstract
Use of statins for primary prevention can reduce all-cause mortality in Asian elderly populations, but their effect and the specific effective subgroups in the elderly Japanese population remain unclear. This study examined the relationship between statin therapy for primary prevention and mortality reduction in older Japanese adults, and investigated the effective subgroups. The cohort study was conducted using the Shizuoka Kokuho Database (SKDB). Data were compared between the statin-treated group and a non-statin-treated (control) group using the inverse probability of treatment weighting (IPTW) method. In the SKDB cohort aged ≥65 years, new statin use was associated with a decreased risk of all-cause mortality (hazard ratio, 0.40; 95% confidence interval [CI], 0.33-0.48) after IPTW adjustment. The risk difference for mortality at 5 years in the statin-treated group compared with that in the control group was 0.05 (95% CI, 0.04-0.06), and the number needed to treat was 21.20 (95% CI, 18.10-24.70). In conclusion, statin use for primary prevention in older adults may reduce the risk of all-cause mortality in the population without atherosclerotic disease. Furthermore, statin use for primary prevention is feasible in patients aged 75 to <85 years and in patients with comorbidities such as diabetes, or dementia.

Abstract
BACKGROUND The aim of this study was to compare moderate- versus high-intensity statin therapy in patients with type 2 diabetes and low-density lipoprotein (LDL) cholesterol less than 130 mg/dL. METHODS This was a randomized, open-label, parallel design trial comprised of 79 patients randomly allocated into two groups receiving high-intensity [atorvastatin 40 mg (A40) or rosuvastatin 20 mg (R20) daily] or moderate-intensity [atorvastatin 20 mg (A20) or rosuvastatin 10 (R10) mg daily] statins for eight weeks. The variables investigated were lipid profile, high sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6). RESULTS The percentage of decrease in LDL levels (±SD) for the high-intensity group (-35.5±25.5) was significantly greater than the moderate-intensity group (-24.6±23.5) (P=0.04). While 38.1% (n:8) of patients receiving A20 and 55% (n:11) of those being on R10 achieved the targets of≥30% reduction in the LDL level, these figures were 63.2% (n=12) and 73.8% (n=14) for A40 and R20 subgroups, respectively. Subsequently, the likelihood of achieving LDL reduction≥30%, was significantly greater with high-intensity statin therapy (OR: 3.1, 95% CI: 1.09, 8.90, P=0.03). Logistic regression analysis also showed that for every 1 mg/ dL increase in the baseline LDL level, the odds of achieving the LDL reduction≥30% increased by 1.04 times [95% CI: (1.01, 1.07), P=0.003]. CONCLUSION Despite the general conception, moderate-intensity statins are not adequate for the majority of patients with T2DM and mild hyperlipidemia and greater numbers of patients could reach the LDL cholesterol target with high-intensity statin therapy.

Abstract
BACKGROUND Chronic low-grade inflammation is associated with both ischemic stroke and sedentary behaviour. The aim of this study was to investigate the predictive abilities of biomarkers of inflammation and immune modulation associated with sedentary behaviour for ischemic stroke recurrence and mortality in a stroke population. METHODS Patients admitted to hospital for acute stroke were recruited to the prospective multicentre cohort study, the Norwegian Cognitive Impairment After Stroke (Nor-COAST) study, from May 2015 until March 2017. Patients with ischemic stroke, blood samples available from the three-month follow-up, and no stroke recurrence before the three-month follow-up were included. Serum was analysed for C-reactive protein (CRP) with high-sensitive technique, and plasma for interleukin-6 (IL-6), neopterin, pyridoxic acid ratio index (PAr-index: 4-pyridoxic acid: [pyrioxal+pyridoxal-5'-phosphate]) and kynurenic acid (KA). Ischemic stroke recurrence and death were identified by the Norwegian Stroke Registry and the Cause of Death Registry until 31 December 2018. RESULTS The study included 354 patients, 57% male, mean age 73 (SD 11) years, mean observation time 2.5 (SD 0.6) years, and median National Institute of Health Stroke Scale of 0 (IQR 1) at three months. CRP was associated with mortality (HR 1.40, CI 1.01, 1.96, p = 0.046), and neopterin was associated with the combined endpoint (recurrent ischemic stroke or death) (HR 1.52, CI 1.06, 2.20, p = 0.023), adjusted for age, sex, prior cerebrovascular disease, modified Rankin Scale, and creatinine. When adding neopterin and KA to the same model, KA was negatively associated (HR 0.57, CI 0.33, 0.97, p = 0.038), and neopterin was positively associated (HR 1.61, CI 1.02, 2.54, p = 0.040) with mortality. Patients with cardioembolic stroke at baseline had higher levels of inflammation at three months. CONCLUSION Neopterin might be a valuable prognostic biomarker in stroke patients. The use of KA as a measure of anti-inflammatory capacity should be investigated further. TRIAL REGISTRATION The study was registered at Clinicaltrials.gov ( NCT02650531 ). First posted on 08/01/2016.

Abstract
Background Statins reportedly have anti-inflammatory effects aside from their lipid-lowering impact. We investigated the effects of statin therapy on the level of C-reactive protein (CRP) or highly sensitive CRP (hs-CRP), a liver-derived marker of systemic inflammation, among stroke patients. Methods An online search was performed in Scopus, PubMed/MEDLINE, ISI Web of Science, and Google Scholar up to November 2020 to recognize clinical trials investigating the effects of statins on the CRP level in stroke patients. Results Overall, nine studies (11 treatment arms) with 1659 participants met the inclusion criteria. Six out of 9 studies (8 out of 11 arms) were categorized as studies with a high-quality methodological approach using the Cochrane Collaboration's tool. Data from 5 treatment arms indicated a significant decrease in CRP concentration, and in one treatment arm, CRP concentration did not suggest any considerable alteration following statin therapy. Moreover, two treatment arms showed a significant reduction in hs-CRP concentration and three treatment arms revealed no significant alteration in hs-CRP concentration following statin therapy. Generally, results were heterogeneous and independent of the type of statin, statin dose, treatment duration, and changes in plasma low-density lipoprotein cholesterol concentration. Conclusion The results suggest that statin therapy could reduce and, therefore, could be considered in these patients as potential anti-inflammatory agents.

Abstract
AIMS To study the role of cytokines and vascular inflammatory biomarkers in unstable carotid plaque. BACKGROUND Clinical studies showed that not only the degree of stenosis but also the type of carotid plaque can be responsible for ipsilateral ischemic stroke. OBJECTIVE The objective of this study is to suggest a role for vulnerable carotid atherosclerotic disease in the occurrence of ischemic stroke. METHODS PubMed, Embase, Cochrane library, and reference lists have been used to evaluate articles published until February 15, 2021. RESULTS Several factors may be involved in unstable plaque. Clinical studies support the involvement of brain inflammatory biomarkers as well as cytokines in the unstable carotid plaque. CONCLUSIONS Biomarkers could help to stratify patients with a vulnerable carotid plaque and to personalize the drug treatment. In this review, we briefly discuss the characteristics of vulnerable plaque and the role of biomarkers in the vulnerable carotid plaque.

Abstract
Current guidelines for primary and secondary prevention of stroke in patients with carotid atherosclerosis are based on the quantification of the degree of stenosis and symptom status. Recent publications have demonstrated that plaque morphology and composition, independent of the degree of stenosis, are important in the risk stratification of carotid atherosclerotic disease. This finding raises the question as to whether current guidelines are adequate or if they should be updated with new evidence, including imaging for plaque phenotyping, risk stratification, and clinical decision-making in addition to the degree of stenosis. To further this discussion, this roadmap consensus article defines the limits of luminal imaging and highlights the current evidence supporting the role of plaque imaging. Furthermore, we identify gaps in current knowledge and suggest steps to generate high-quality evidence, to add relevant information to guidelines currently based on the quantification of stenosis.

Abstract
Modern causal mediation theory has formalized several types of indirect and direct effects of treatment on outcomes regarding specific mediator variables. We reviewed and unified distinct approaches to estimate the "interventional" direct and indirect effects for multiple mediators and time-varying variables. This study was motivated by a clinical trial of elderly type-2 diabetic patients in which atorvastatin was widely prescribed to control patients' cholesterol levels to reduce diabetic complications, including cardiovascular disease. Among atorvastatin's preventive side-effects (pleiotropic effects), we focus on its anti-inflammatory action as measured by white blood cell counts. Hence, we estimate atorvastatin's interventional indirect effects through cholesterol lowering and through anti-inflammatory action, and interventional direct effect bypassing these two actions. In our analysis, total effect (six-year cardiovascular disease risk difference) estimated by standard plug-in g-formula of -3.65% (95% confidence interval: -10.29%, 4.38%) is decomposed into indirect effect via low-density lipoprotein cholesterol (-0.90% [-1.91%, -0.07%]), via white blood cell counts (-0.03% [-0.22%, 0.11%]), and direct effect (-2.84% [-9.71%, 5.41%]) by the proposed parametric mediational g-formula. The SAS program and its evaluation via simulated datasets are provided in the Supplemental materials.

Abstract
Introduction: Reducing low-density lipoprotein cholesterol (LDL-C) with lipid-lowering therapies has been associated with a decrease in the frequency of cardiovascular events.Areas covered: A systematic search was conducted on PubMed (MEDLINE), using the MeSH terms [Rosuvastatin] + [Ezetimibe] + [Dyslipidemia] + [treatment]. Original data from clinical trials, prospective and retrospective studies and more useful reviews were selected.Expert opinion: While statins continue to be the cornerstone of dyslipidemia management, many patients do not attain LDL-C targets with high-intensity statins alone. Rosuvastatin is a high-intensity statin with a low risk of adverse effects and drug-drug interactions and proven benefits in the prevention of cardiovascular disease. Rosuvastatin and ezetimibe have complementary mechanisms of action that enhance their ability to reduce LDL-C levels. Various studies have shown that the combination of rosuvastatin 10-40 mg and ezetimibe 10 mg enables considerable reductions in LDL-C (up to 60-75%) with a good safety profile in a broad spectrum of patients with hypercholesterolemia, including those at high risk and those with atherosclerotic cardiovascular disease. In addition, a fixed-dose combination of rosuvastatin and ezetimibe may improve adherence to medication. In this review, the available evidence on the combination of rosuvastatin and ezetimibe is updated.

Abstract
Statins, 3-hydroxy-methylglutaryl coenzyme A reductase inhibitors, have been used for decades for the prevention of coronary artery disease and stroke. They act primarily by lowering serum cholesterol through the inhibition of cholesterol synthesis in the liver, which results in the upregulation of low-density lipoprotein receptors in the liver. This results in the removal of low-density lipoproteincholesterol. Studies have suggested that statins may demonstrate additional effects that are independent of their effects on low-density lipoprotein-cholesterol. These have been termed "pleiotropic" effects. Pleiotropic effects may be due to the inhibition of isoprenoid intermediates by statins. Isoprenoid inhibition has effects on the small guanosine triphosphate binding proteins Rac and Rho which in turn effects nicotinamide adenine dinucleotide phosphate oxidases. Therefore, there are changes in endothelial nitric oxide synthase expression, atherosclerotic plaque stability, pro-inflammatory cytokines and reactive oxygen species production, platelet reactivity, and cardiac fibrosis and hypetrophy development. Recently, statins have been compared to the ezetimibe and the recently published outcomes data on the proprotein convertase subtilisin kexin type 9 inhibitors has allowed for a reexamination of statin pleiotropy. As a result of these diverse effects, it has been suggested that statins also have anti-arrhythmic effects. This review focuses on the mechanisms of statin pleiotropy and discusses evidence from the statin clinical trials as well as examining the possible anti-arrhythmic effects atrial fibrillation and ventricular tachyarrhythmias.

Abstract
Inflammatory bowel disease is a chronic autoimmune disorder of the western world that is rapidly expanding in newly industrialized countries. Novel strategies are urgently needed to prevent and improve the treatment of this costly and disabling disease. Statins are the most commonly prescribed drugs worldwide. Besides their lipid-lowering effects, statins may exert complex immunomodulatory properties and multiple pleiotropic effects including the inhibition of T-cell activation, antigen-presenting function and leukocyte infiltration of target organs which might render statins as beneficial agents for inflammatory and autoimmune conditions. In this review, we summarize the experimental findings on the topic, and critically appraise the epidemiological evidence regarding the value of statins as a potential strategy for preventing and treating inflammatory bowel disease. Several experimental studies have shown that statins reduce inflammation in animal models of colitis; however, clinical studies investigating their disease-modifying and preventive potential in IBD have demonstrated some limitations and conflicting results. The available epidemiological evidence is not yet sufficient to support the use of statin for preventing or treating inflammatory bowel disease. Additional high-quality research is warranted.

Abstract
OBJECTIVES Although several studies have shown that interventions to lower blood lipid concentration may reduce the risk of coronary arterial disease and ischemic stroke, the correlation between serum lipid levels and hemorrhagic stroke remains controversial. To clarify any possible association between serum lipid and hematoma expansion, we examined various serum lipid indices in patients with and without early hematoma expansion. METHODS Data of 572 intracerebral hemorrhage (ICH) patients from the cerebral small vessel disease cohort of Peking Union Medical College Hospital were retrospectively analyzed. Patients who finished the baseline brain computed tomography (CT) examination within 6 h post-ictus and the follow-up CT within 48 h after initial CT were included in the study. Hematoma expansion was delimited as an enlargement of hemorrhage volume over 33% or 12.5 mL between baseline and subsequent CT. Both uni- and multivariate logistic regression analyses were conducted to explore the association between early hematoma growth and various serum lipid indices, including triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), non-HDL-C, ratios of LDL-C/HDL-C and LDL-C/TC, as well as other demographic and clinical features. RESULTS Out of 157 patients included in the analysis, hematoma growth occurred in 45 (28.7%). Only higher baseline systolic blood pressure was found to be correlated with an increased risk of hematoma growth based on both univariate (odds ratio [OR] 1.014, 95% confidence interval [CI]: 1.002-1.026, P = .024) and multivariate logistic regression analyses (OR 1.022, 95%CI: 1.008-1.037, P = .003). No associations were detected between the various serum lipid indices examined and other clinical features with a likelihood of early hematoma growth between groups or within various subgroups defined by different characteristics including age, gender, baseline Glasgow Coma Scale score, systolic blood pressure, intraventricular extension, and hematoma location. CONCLUSIONS No association between various indices of serum lipid and hematoma growth was identified among patients and subgroups with spontaneous ICH in the Chinese population; these findings may help to guide lipid management after ICH. However, further multi-centered, larger scale studies are expected to verify our results.

Abstract
INTRODUCTION Statins are known to lower CRP, and this reduction has been suggested to contribute to the established efficacy of these drugs in reducing cardiovascular events and outcomes. However, the exact mechanism underlying the CRP-lowering effect of statins remains elusive. METHODS In order to test the possibility of direct interaction, we performed an in silico study by testing the orientation of the respective ligands (statins) and phosphorylcholine (the standard ligand of CRP) in the CRP active site using Molecular Operating Environment (MOE) software. RESULTS Docking experiments showed that all statins could directly interact with CRP. Among statins, rosuvastatin had the strongest interaction with CRP (pKi = 16.14), followed by fluvastatin (pKi = 15.58), pitavastatin (pKi = 15.26), atorvastatin (pKi = 14.68), pravastatin (pKi = 13.95), simvastatin (pKi = 7.98) and lovastatin (pKi = 7.10). According to the above-mentioned results, rosuvastatin, fluvastatin, pitavastatin and atorvastatin were found to have stronger binding to CRP compared with the standard ligand phosphocholine (pKi = 14.55). CONCLUSIONS This finding suggests a new mechanism of interaction between statins and CRP that could be independent of the putative cholesterol-lowering activity of statins.

Abstract
OBJECTIVE Statins are a class of drugs that competitively bind to the active site of HMG-CoA reductase enzyme, thereby inhibiting the initial steps in cholesterol synthesis. Originally approved for use in lowering serum cholesterol, a risk factor for developing atherosclerosis and coronary heart disease, statins have subsequently been noted to have myriad extrahepatic effects, including potential effects on cognition, diabetes, breast cancer, bone, and muscle. This narrative review assesses the current state of the science regarding the risks and benefits of statin therapy in women to identify areas where additional research is needed. METHODS Basic and clinical studies were identified by searching PubMed with particular attention to inclusion of female animals, women, randomized controlled trials, and sex-specific analyses. RESULTS Statin therapy is generally recommended to reduce the risk of cardiovascular disease. None of the current clinical guidelines, however, offer sex-specific recommendations for women due to lack of understanding of sex differences and underlying mechanisms of disease processes. In addition, conclusions regarding efficacy of treatments do not consider lipid solubility for the drug, dosing, duration of treatment, interactions with estrogen, or comorbidities. Pleiotropic effects of statins are often derived from secondary analysis of studies with cardiovascular events as primary outcomes. CONCLUSIONS Many of the trials that have established the efficacy and safety of statins were conducted predominantly or entirely in men, with results extrapolated to women. Additional research is needed to guide clinical recommendations specific to women. : Video Summary:http://links.lww.com/MENO/A462.

Abstract
BACKGROUND AND AIMS To reassess the effect of statin-based lipid-lowering therapy on ischemic stroke in primary and secondary prevention trials with regard to achieved levels of low-density lipoprotein-cholesterol in view of the availability of novel potent hypolipidemic agents. METHODS English literature was searched (up to November 2018) for publications restricted to trials with a minimum enrolment of 1000 and 500 subjects for primary and secondary prevention, respectively, meeting the following criteria: adult population, randomized controlled design, and recorded outcome data on ischemic stroke events. Data were meta-analyzed and curve-estimation procedure was applied to estimate regression statistics and produce related plots. RESULTS Four primary prevention trials and four secondary prevention trials fulfilled the eligibility criteria. Lipid-lowering therapy was associated with a lower risk of ischemic stroke in primary (risk ratio, RR 0.70, 95% confidence interval, CI, 0.60-0.82; p < 0.001) and in the secondary prevention setting (RR 0.80, 95% CI 0.70-0.90; p < 0.001). Curve-estimation procedure revealed a linear relationship between the absolute risk reduction of ischemic stroke and active treatment-achieved low-density lipoprotein-cholesterol levels in secondary prevention (adjusted R-square 0.90) in support of "the lower the better" hypothesis for stroke survivors. On the other hand, the cubic model followed the observed data well in primary prevention (adjusted R-square 0.98), indicating greater absolute risk reduction in high-risk cardiovascular disease-free individuals. CONCLUSIONS Statin-based lipid-lowering is effective both for primary and secondary prevention of ischemic stroke. Most benefit derives from targeting disease-free individuals at high cardiovascular risk, and by achieving low treatment targets for low-density lipoprotein-cholesterol in stroke survivors.

Abstract
Atherosclerotic cardiovascular disease (ASCVD) remains a leading cause of morbidity and mortality despite excellent pharmacological and revascularization approaches. Low-density lipoproteins (LDL) are undoubtedly the most significant biochemical variables associated with atheroma, however, compelling data identify inflammation as critical for the maintenance of the atherosclerotic process, underlying some of the most feared vascular complications. Although its causal role is questionable, high-sensitivity C-reactive protein (hs-CRP) represents a major biomarker of inflammation and associated risk in CVD. While statin-associated reduced risk may be related to the lowering of both LDL-C and hs-CRP, PCSK9 inhibitors leading to dramatic LDL-C reductions do no alter hs-CRP levels. On the other hand, hs-CRP levels identify groups of patients with a high risk of CV disease achieving better ASCVD prevention in response to PCSK9 inhibition. In the FOURIER study, even in patients with extremely low levels of LDL-C, there was a stepwise risk increment according to the values of hs-CRP: +9% (<1 mg/L), +10.8% (1-3 mg/L) and +13.1% (>3 mg/L). Likewise, in the SPIRE-1 and -2 studies, bococizumab patients with hs-CRP> 3 mg/L had a 60% greater risk of future CV events. Most of the patients enrolled in the PCSK9 trials were on maximally tolerated statin therapy at baseline, and an elevated hs-CRP may reflect residual inflammatory risk after standard LDL-C lowering therapy. Moreover, data on changes in inflammation markers in carriers of PCSK9 loss-of-function mutations are scanty and not conclusive, thus, evidence from the effects of anti-inflammatory molecules on PCSK9 levels might help unravel this hitherto complex tangle.

Abstract
BACKGROUND The American College of Cardiology and American Heart Association (ACC/AHA) issued new cholesterol treatment guidelines in 2013. Two of the groups designated for primary prevention were analyzed: patients with a low-density lipoprotein cholesterol (LDL-C) level ≥ 190 mg per dL and diabetic patients aged 40-75 years. OBJECTIVE To estimate the effects of primary prevention as specified in the 2013 guidelines on cardiovascular event risk and cost. METHODS Primary prevention patients were identified using laboratory and diagnostic data for Humana members from 2007 to 2013. Potential study patients were classified into 3 risk groups: elevated LDL-C, diabetes, and elevated LDL-C and diabetes. Patients receiving cholesterol-lowering medications before their index date were excluded. Eligible patients were divided into 2 treatment groups: (1) primary prevention patients who initiated treatment before experiencing any cardiovascular disease (CVD)-related event, and (2) patients who either did not initiate treatment until after experiencing a CVD event or never initiated treatment. The associations between initiating cholesterol-lowering medications for primary prevention and the risk for acute myocardial infarction, stroke, coronary angioplasty, or coronary artery bypass graft surgery were estimated using Cox proportional hazards models. The effect of primary prevention on health care costs was estimated using generalized linear models. RESULTS 91,066 patients met study selection criteria. Primary prevention rates were the lowest in diabetic patients (35%), who were newly designated for treatment in the 2013 guidelines. Primary prevention rates were higher for patients designated for treatment under earlier guidelines: 65% for patients with elevated LDL-C and 78% for the combined LDL-C and diabetes group. Primary prevention treatment was associated with significant reductions in cardiovascular event risk (up to 37%) and lower total all-cause costs (by $673) in the first post-index year. CONCLUSIONS Initiating cholesterol-lowering medications for primary prevention, as specified in the ACC/AHA 2013 guidelines, for patients with high LDL-C and diabetes is associated with reduced CVD event risks and lower health care costs. DISCLOSURES No outside funding supported this study. Han received fellowship support from the Pharmaceutical Research and Manufacturers Association Foundation (PhRMA) during the conduct of this study. Dougherty is employed by PhRMA.

Abstract
Atherosclerosis is a major cause of ischemic stroke that can be effectively prevented with appropriate lifestyle modifications and control of cardiovascular risk factors. Medical advances in recent years along with aggressive cardiovascular risk factor modifications have resulted in decreased recurrence rates of atherosclerotic stroke. Non-statin lipid-lowering molecules have recently shown clinical benefit and are recommended for very high-risk patients to reduce their risk of stroke. Aggressive hypertension treatment is crucial to reduce atherosclerotic stroke risk. Advances in antithrombotic treatments include combinations of antiplatelets and new antiplatelet agents in the acute phase post-stroke, which carries a high risk of recurrence. Intensive medical treatment has also limited the indications for carotid interventions, especially for asymptomatic disease. Intracranial atherosclerotic disease may provoke stroke through various mechanisms; it is increasingly recognized as a cause of ischemic stroke with advanced imaging and is best managed with lifestyle modifications and medical therapy. The diagnostic search for the vulnerable culprit atherosclerotic plaque is an area of intense research, from the level of the intracranial arteries to that of the aortic arch. Ultrasonography and novel magnetic resonance imaging techniques (high-resolution vessel-wall imaging) may assist in the identification of vulnerable atherosclerotic plaques as the underlying cause in cryptogenic or misdiagnosed non-atherosclerotic ischemic stroke. Vertebrobasilar atherosclerotic disease is less common than carotid artery disease; thus, high-quality data on effective prevention strategies are scarcer. However, aggressive medical treatment is also the gold standard to reduce cerebrovascular disease located in posterior circulation.

Abstract
PURPOSE Estimating how much of the impact of statins on coronary heart diseases (CHD), cardiovascular disease (CVD), and mortality risk is attributable to their effect on low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and triglycerides. METHODS A semi-parametric g-formula estimator together with data from the Multi-Ethnic Study of Atherosclerosis (a prospective multi-center cohort study) was utilized to perform a mediation analysis. A total of 5280 participants, men and women of various race/ethnicities from multiple sites across the United States, were considered in the current study. RESULTS The adherence adjusted total relative risk reduction (RRR) estimate (95% confidence interval) of statins on CHD was 14% (-16%, 37%), and the indirect component through LDL was 23% (-4%, 58%). For CVD, the total RRR was 23% (2%, 40%), and the indirect component through LDL was 5% (-13%, 25%). The total RRR of mortality was 18% (-1%, 35%), and the indirect component through LDL was -4% (-17%, 12%). The estimated indirect components through HDL and triglycerides were close to zero with narrow confidence intervals for all 3 outcomes. CONCLUSIONS The estimated effect of statins on mortality, CVD, and CHD appeared to be independent of their estimated effect on HDL and triglycerides. Our study provides evidence that the preventive effect of statins on CHD could be attributed in large part to their effect on LDL. Our g-formula estimator is a promising approach to elucidate pathways, even if it is hard to make firm conclusions for the LDL pathway on mortality and CVD.

Abstract
The statins have been used for 30 years to prevent coronary artery disease and stroke. Their primary mechanism of action is the lowering of serum cholesterol through inhibiting hepatic cholesterol biosynthesis thereby upregulating the hepatic low-density lipoprotein (LDL) receptors and increasing the clearance of LDL-cholesterol. Statins may exert cardiovascular protective effects that are independent of LDL-cholesterol lowering called pleiotropic effects. Because statins inhibit the production of isoprenoid intermediates in the cholesterol biosynthetic pathway, the post-translational prenylation of small GTP-binding proteins such as Rho and Rac, and their downstream effectors such as Rho kinase and nicotinamide adenine dinucleotide phosphate oxidases are also inhibited. In cell culture and animal studies, these effects alter the expression of endothelial nitric oxide synthase, the stability of atherosclerotic plaques, the production of proinflammatory cytokines and reactive oxygen species, the reactivity of platelets, and the development of cardiac hypertrophy and fibrosis. The relative contributions of statin pleiotropy to clinical outcomes, however, remain a matter of debate and are hard to quantify because the degree of isoprenoid inhibition by statins correlates to some extent with the amount of LDL-cholesterol reduction. This review examines some of the currently proposed molecular mechanisms for statin pleiotropy and discusses whether they could have any clinical relevance in cardiovascular disease.

Abstract
BACKGROUND Patients with high total cholesterol have increased risk of cardiovascular disease. National Cholesterol Education Program (NCEP) and American Heart Association (AHA) guidelines recommend cholesterol lowering with statin medications; however, statin adherence remains poor. We hypothesized that patient-centered education on the 10-year risk for each of the major constituents of cardiovascular disease would increase statin adherence and achievement of the low-density lipoprotein cholesterol (LDL-C) goal. METHODS Veterans within the Salt Lake City Veterans Affairs (VA) Medical Center initiating statin therapy from October 2008 to December 2011 were randomized in a pragmatic design to receive either an educational mailer or usual care. The mailer outlined their 10-year global cardiovascular risk, separated into coronary heart disease, stroke, and congestive heart failure. The study was unblinded and followed an intention-to-treat analysis where outcome measures were obtained during normal care process. The primary outcome measure was the achievement of the LDL-C goal during the 12-month follow-up. RESULTS Two hundred and seven patients were randomly assigned to either the intervention arm (95) or the control arm (112). No differences in the proportion of patients meeting the LDL-C goal were detected during 12-months [Relative Risk (RR): 0.95 (95 percent confidence interval (CI): 0.77-1.17)] or 18-months [RR: 1.03 (95 percent CI: 0.84, 1.25)]. Patients in the intervention arm had higher adherence on average, e.g., intervention patients were more likely to have 70 percent or more days of statin therapy compared to patients who received standard care-though this did not reach statistical significance-RR: 1.33 (95 percent CI: 1.00, 1.78). There were no statistical differences in cardiovascular outcomes or mortality. CONCLUSION Patient education mailers sent to patients starting statin treatment did not have a clear impact on LDL-C goal achievement or adherence to statin therapy.

Abstract
Dyslipidemia is one of the major modifiable risk factors associated with atherosclerotic cardiovascular disease. Appropriate modification of lipid profiles reduces the progression of atherosclerosis in vessel walls across all vascular beds. The management of dyslipidemia has evolved over the last several decades, especially since the discovery of 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors, also known as statins. Statin use in atherosclerotic heart disease is well described in observational and prospective placebo-controlled studies, citing both lipid-lowering and pleiotropic effects. However, the effect of statins and other lipid-lowering agents on noncoronary arterial beds (the aorta, arteries to the extremities, renal, and carotid arteries) is less understood. This article is part 2 of a 2-part review, with part 1 having focused on lipid metabolism and the downstream effects of lipids on the development of atherosclerosis. The current review (part 2) will discuss trials, retrospective reviews, and observational cohort studies regarding the use of statins and/or other lipid-lowering drugs for primary and secondary prevention of peripheral noncoronary atherosclerotic disease.

Abstract
OBJECTIVES Complicated aortic arch plaques (CAP) and their progression are important for recurrent ischemic stroke (IS) and its prognosis. We investigated the effects and clinical benefits of rosuvastatin therapy on this pathophysiology. The purpose of this study was to investigate whether rosuvastatin prevention of aortic arch plaque progression improved the prognosis of IS patients. METHODS Ninety-seven consecutive acute cerebral embolism patients were retrospectively surveyed. All had transesophageal echocardiography (TEE) to assess the presence or absence of CAP, defined as aortic wall thickness ≥4 mm or plaque ulceration. Patients received conventional antithrombotic therapy as clinically indicated. All patients with CAP were recommended to receive 5 mg rosuvastatin/day, administered by their attending physicians; not all physicians followed this recommendation. Six-month follow-up TEEs were performed in patients with CAP who received rosuvastatin. Major adverse cerebrovascular events (MACEs) comprised recurrent IS and death. RESULTS CAP was detected in 39 patients (40%), and MACEs in 15. Multivariate regression analysis showed that patients with CAP not taking rosuvastatin was an independent risk factor for MACEs (odds ratio = 18.044; 95% confidential interval = 2.089-155.846, p < 0.01). When patients were divided into three groups: those with CAP taking rosuvastatin, those with CAP not taking rosuvastatin, and those without CAP, Kaplan-Meier analysis demonstrated that patients with CAP not taking rosuvastatin had significantly more MACEs than those in the other two groups (long-rank test; χ2 = 6.553, p < 0.05). Six-month TEE follow-ups in the 26 patients with CAP taking rosuvastatin showed significant improvement in CAP diameter with improved lipid profiles; 88% (23/26 patients) showed no morphological CAP progression; 15 of these showed CAP regression. DISCUSSION Rosuvastatin therapy prevented aortic arch plaque progression in IS patients with CAP, and may also have long-term clinical benefits.

Abstract
A global heart failure (HF) registry suggested that the inverse association between body mass index (BMI) and all-cause mortality differed by race, particularly stronger in Japanese patients at 1-year follow-up. Whether this finding was consistent across all East Asian populations was unknown. In a multicenter prospective study in Taiwan, we enrolled 1,301 patients hospitalized for systolic HF from 2013 to 2014 and followed up the mortality after their discharge for a median of 1-year period. Cox proportional hazard regression analyses were used to assess the association of BMI with all-cause mortality. The results showed that BMI was inversely associated with all-cause mortality (hazard ratio and 95% CI per 5-kg/m(2) increase: 0.75 [0.62 to 0.91]) after adjusting for demographics, traditional risk factors, HF severity, and medications at discharge. Subsequently, we sought previous studies regarding the BMI association with mortality for East Asian patients with HF from Medline, and a random-effect meta-analysis was performed by the inverse variance method. The meta-analysis including 7 previous eligible studies (3 for the Chinese and 4 for the Japanese cohorts) and the present one showed similar results that BMI was inversely associated with all-cause mortality (hazard ratio 0.65 [0.58 to 0.73], I(2) = 37%). In conclusion, our study in Taiwan and a collaborative meta-analysis confirmed a strong inverse BMI-mortality association consistently among East Asian patients with HF.

Abstract
BACKGROUND/PURPOSE A reduction of cardiovascular events has been reported in phase 2 and 3 trials of the proprotein convertase subtilisin kexin 9 (PCSK9) inhibitors alirocumab and evolocumab. We aimed to investigate the effect PCSK9 inhibition on stroke risk in a meta-analysis involving data from randomized studies with alirocumab and evolocumab. METHODS Data from pre-specified combined analysis of 4465 patients who completed phase 2 or 3 studies of evolocumab over a period of 1year and a randomized trial on alirocumab including 2341 patients with hyperlipidemia on maximally tolerated statin who were at high risk for coronary heart disease over a period of 1.5years were used. RESULTS The number of patients having an ischemic stroke was small in both trials. PCSK9 inhibition showed no significant effect on stroke rate (risk ratio 1.43; 95% CI, 0.45-4.57, p=0.55). No significant differences in stroke risk were evident when transient ischemic attacks were included in the analysis (risk ratio 0.65; 95% CI, 0.25-1.68, p=0.37). No hemorrhagic strokes were reported in either study. CONCLUSION Although a benefit towards reduction of cardiovascular events in the overall has been documented, longer exposure is warranted to be able to evaluate the effect on stroke risk.

Abstract
BACKGROUND Previous study indicated that high-dose statin treatment might increase the risk of hemorrhagic stroke and adverse reactions. We aim to compare the efficacy and safety of intensive-dose and standard-dose statin treatment for preventing stroke in high-risk patients. METHODS A thorough search was performed of multiple databases for publications from 1990 to June 2015. We selected the randomized clinical trials comparing standard-dose statin with placebo and intensive-dose statin with standard-dose statin or placebo for the prevention of stroke events in patients. Duplicate independent data extraction and bias assessments were performed. Data were pooled using a fixed-effects model or a random-effects model if significant heterogeneity was present. RESULTS For the all stroke incidences, intensive-dose statin treatment compared with placebo treatment and standard-dose statin treatment compared with placebo treatment showed a significant 21% reduction in relative risk (RR) (RR 0.79, 95% confidence interval (CI) [0.71, 0.87], P < 0.00001) and an 18% reduction in RR (RR 0.82, 95% CI [0.73, 0.93], P = 0.002) in the subgroup without renal transplant recipients and patients undergoing regular hemodialysis separately. For the fatal stroke incidences, intensive-dose statin treatment compared with standard dose or placebo was effective reducing fatal stroke (RR 0.61, 95% CI [0.39, 0.96], P = 0.03) and the RR was 1.01 (95% CI [0.85, 1.20], P = 0.90) in standard-dose statin treatment compared with placebo. CONCLUSION The results of this meta-analysis suggest that intensive-dose statin treatment might be more favorable for reducing the incidences of all strokes than standard-dose statin treatment, especially for patients older than 65 years in reducing the incidences of all stroke incidences.

Abstract
Cardiovascular disease (CVD) has been the number one cause of death in the U.S. for 114 of the last 115 years. Lifestyle factors that promote CVD also appear to increase prostate cancer risk and those that reduce CVD risk also appear to reduce the risk of prostate cancer. The largest randomized trials utilizing dietary supplements or pharmacologic agents for prostate cancer prevention (Selenium and Vitamin E Cancer Prevention Trial [SELECT]) have also shed light on the problems and future solutions in this area. Dietary supplements that have not been found to be CVD protective, such as selenium and Vitamin E have not been found to be prostate protective. In addition, over exposure to specific anti-oxidants in nutritionally replete populations may be encouraging cancer growth. Future trials of dietary supplements to prevent prostate cancer could be problematic because by the time a definitive trial is initiated the participants will no longer be “deficient” in the nutrient being tested, which arguably occurred in the SELECT trial. It is also interesting that statins, aspirin, and/or metformin (S.A.M.) are 3 generic, low-cost, heart healthy agents derived from natural sources with separate mechanism of actions, which all appear to have the best benefit to risk ratio compared to any other agent available for prostate cancer prevention, especially aggressive disease, or as an ancillary agent (s) to conventional cancer treatment. It is time to focus on the forest over the trees and recommend proven CVD protective measures for men concerned about their risk of prostate cancer.

Abstract
HIV-1-associated neurocognitive disorder (HAND) remains a persistent problem despite antiretroviral therapy (ART), largely a result of continued inflammation in the periphery and the brain and neurotoxin release from activated myeloid cells in the CNS. CD14+CD16+ inflammatory monocytes, expanded in HIV infection, play a central role in the pathogenesis of HAND and have parallels with monocyte-dependent inflammatory mechanisms in atherosclerosis. Statins, through their HMG-CoA reductase inhibitor activity, have pleiotropic immunomodulatory properties that contribute to their benefit in atherosclerosis beyond lipid lowering. Here, we investigated whether statins would modulate the monocyte phenotype and function associated with HIV-1 neuropathogenesis. Treatment ex vivo with simvastatin and atorvastatin reduced the proportion of CD16+ monocytes in peripheral blood mononuclear cells, as well as in purified monocytes, especially CD14++CD16+ "intermediate" monocytes most closely associated with neurocognitive disease. Statin treatment also markedly reduced expression of CD163, which is also linked to HAND pathogenesis. Finally, simvastatin inhibited production of monocyte chemoattractant protein-1 (MCP-1) and other inflammatory cytokines following LPS stimulation and reduced monocyte chemotaxis in response to MCP-1, a major driver of myeloid cell accumulation in the CNS in HAND. Together, these findings suggest that statin drugs may be useful to prevent or reduce HAND in HIV-1-infected subjects on ART with persistent monocyte activation and inflammation.

Abstract
OPINION STATEMENT Statins are a group of lipid-lowering agents that are competitive inhibitors of the enzyme 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase that have been used to reduce cholesterol levels and prevent cardiovascular events. Statins have been also shown to reduce the risk of stroke. In this review, we cover the role of statins in cerebrovascular disease through lipid-lowering mechanisms and other "pleiotropic" effects that provide protection against cerebrovascular events and potentially contribute to improve functional outcome after stroke.

Abstract
OBJECTIVE The aim of this work was to assess efficacy and tolerability of simvastatin plus vitamin D for migraine prevention in adults with episodic migraine. METHODS We performed a randomized, double-blind, placebo-controlled trial with a 12-week baseline period and 24-week intervention period in 57 adults with episodic migraine. Participants were randomly assigned to simvastatin 20 mg tablets twice-daily plus vitamin D3 1,000 international units capsules twice-daily or matching placebo tablets and capsules. RESULTS Compared to placebo, participants using simvastatin plus vitamin D3 demonstrated a greater decrease in number of migraine days from the baseline period to intervention weeks 1 to 12: a change of -8.0 (interquartile range [IQR]: -15.0 to -2.0) days in the active treatment group versus +1.0 (IQR: -1.0 to + 6.0) days in the placebo group, p < 0.001; and to intervention weeks 13 to 24: a change of -9.0 (IQR: -13 to -5) days in the active group versus +3.0 (IQR: -1.0 to + 5.0) days in the placebo group, p < 0.001. In the active treatment group, 8 patients (25%) experienced 50% reduction in the number of migraine days at 12 weeks and 9 (29%) at 24 weeks postrandomization. In comparison, only 1 patient (3%) in the placebo group (p = 0.03) experienced such a reduction. Adverse events were similar in both active treatment and placebo groups. INTERPRETATION The results demonstrate that simvastatin plus vitamin D is effective for prevention of headache in adults with episodic migraine. Given statins' ability to repair endothelial dysfunction, this economical approach may also reduce the increased risk for vascular diseases among migraineurs.

Abstract
BACKGROUND High-sensitivity C-reactive protein (hsCRP), a marker of systemic inflammation, may promote atherosclerosis, particularly among adults with elevated blood pressure; however, data are sparse. We examined the association between hsCRP concentrations and risk of total stroke by hypertension status (normotension, prehypertension, and hypertension) among men in the Physicians' Health Study (PHS). METHODS AND RESULTS Blood samples were collected (1996-1997) and assayed for hsCRP among 10 456 initially healthy men from PHS I and PHS II and followed from 1997 to 2012. Self-reported hypertension status, cardiovascular risk factors, lifestyle, and alcohol consumption were obtained from the baseline questionnaire prior to randomization in PHS II. Strokes were updated approximately annually and confirmed by medical records according to the National Survey of Stroke criteria. Multivariable Cox models were used. We observed 395 incident total strokes over 115 791 person-years. In analyses adjusted for potential confounders and stroke risk factors, clinically elevated hsCRP (>3 mg/L) was associated with a 40% significantly greater hazard of total stroke compared with hsCRP <1 mg/L (hazard ratio 1.40, 95% CI 1.06 to 1.87; Ptrend=0.01). Additional adjustment for blood pressure and biomarkers associated with cardiovascular risk marginally attenuated the estimates. Results were similar by hypertension status, although not statistically significant among normotensive and prehypertensive participants due to limited events. CONCLUSIONS Elevated hsCRP levels were associated with a greater risk of total stroke, even after adjustment for potential confounders and cardiovascular risk factors. Risk of total stroke was significantly higher among hypertensive men with elevated hsCRP compared with normotensive men with low hsCRP.

Abstract
PURPOSE Perioperative stroke is associated with significant morbidity and mortality, with an incidence that may be underappreciated. In this review, we examine the significance, pathophysiology, risk factors, and evidence-based recommendations for the prevention and management of perioperative stroke. SOURCE This is a narrative review based on literature from the PubMed database regarding perioperative stroke across a broad surgical population. The Society for Neuroscience in Anesthesiology and Critical Care recently published evidence-based recommendations for perioperative management of patients at high risk for stroke; these recommendations were analyzed and incorporated into this review. PRINCIPAL FINDINGS The incidence of overt perioperative stroke is highest in patients presenting for cardiac and major vascular surgery, although preliminary data suggest that the incidence of covert stroke may be as high as 10% in non-cardiac surgery patients. The pathophysiology of perioperative stroke involves different pathways. Thrombotic stroke can result from increased inflammation and hypercoagulability; cardioembolic stroke can result from disease states such as atrial fibrillation, and tissue hypoxia from anemia can result from the combination of anemia and beta-blockade. Across large-scale database studies, common risk factors for perioperative stroke include advanced age, history of cerebrovascular disease, ischemic heart disease, congestive heart failure, atrial fibrillation, and renal disease. Recommendations for prevention and management of perioperative stroke are evolving, though further work is needed to clarify the role of proposed modifiable risk factors such as perioperative anticoagulation, antiplatelet therapy, appropriate transfusion thresholds, and perioperative beta-blockade. CONCLUSIONS Perioperative stroke carries a significant clinical burden. The incidence of perioperative stroke may be higher than previously recognized, and there are diverse pathophysiologic mechanisms. There are many opportunities for further investigation of the pathophysiology, prevention, and management of perioperative stroke.

Abstract
Statins or 3-hydroxy-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors not only prevents the synthesis of cholesterol biosynthesis but also inhibits the synthesis of essential isoprenoid intermediates such as farnesyl pyrophosphate, geranylgeranyl pyrophosphate, isopentanyl adenosine, dolichols and polyisoprenoid side chains of ubiquinone, heme A, and nuclear lamins. These isoprenoid intermediates are required for activation of various intracellular/signaling proteins- small guanosine triphosphate bound protein Ras and Ras-like proteins like Rho, Rab, Rac, Ral, or Rap which plays an indispensible role in multiple cellular processes. Reduction of circulating isoprenoids intermediates as a result of HMG CoA reductase inhibition by statins prevents activation of these signalling proteins. Hence, the multiple effects of statins such as antiinflammatory effects, antioxidant effects, antiproliferative and immunomodulatory effects, plaque stability, normalization of sympathetic outflow, and prevention of platelet aggregation are due to reduction of circulating isoprenoids and hence inactivation of signalling proteins. These multiple lipid-independent effects of statins termed as statin pleiotropy would potentially open floodgates for research in multiple treatment domains catching attentions of researchers and clinician across the globe.

Abstract
We conducted a meta-analysis of 13 randomized trials comparing the efficacy of rosuvastatin versus atorvastatin in reducing concentrations of C-reactive protein (CRP). We searched PubMed, Ovid, and Elsevier databases until June 2014. Search terms included C-reactive protein or CRP, rosuvastatin, atorvastatin, randomized, randomly, and randomization; 13 trials (3798 patients) were included. Funnel plots for CRP were inspected to assess publication bias. The pooled analysis demonstrated the benefit of rosuvastatin over atorvastatin therapy for all 13 trials (mean difference [MD] = −0.11, which is standardized mean with no unit although the raw data before pooling is mg/L, 95% confidence interval −0.15 to −0.07, P < .0001) with no evidence of significant publication bias (I2 = 6.9%, P = .377). Subgroup analysis indicated a significant benefit of rosuvastatin over atorvastatin regarding the 1/1 dose ratio (MD = −0.14, 95% CI −0.21 to −0.06) and 1/2 dose ratio (MD= −0.11, 95% CI −0.16 to −0.05). Cumulative and influence analyses showed accuracy and stability for the estimation mentioned earlier. Our meta-analysis shows that rosuvastatin produces better reduction in CRP concentrations than atorvastatin at a dose ratio of 1/1 and 1/2 (rosuvastatin/atorvastatin), respectively.

Abstract
Stroke remains to be a leading cause of disability. However, optimal strategies can prevent up to 80% of strokes. A large body of evidence supports many strategies for primary and secondary prevention of stroke. The purpose of this paper is to highlight recent major advances for management of modifiable medical and behavioral risk factors of stroke. Specific studies are highlighted, including those related to atrial fibrillation (AF), hypertension, revascularization, hyperlipidemia, antiplatelets, smoking, diet, and physical activity. Effective strategies include the use of novel oral anticoagulants for AF, antiplatelet therapy, and intensive lowering of atherosclerosis risk factors.

Abstract
BACKGROUND Venous thromboembolism (VTE) is common in clinical practice. The efficacy of statins in the primary prevention of VTE remains unproven. This is an update of the review first published in 2011. OBJECTIVES To assess the efficacy of statins in the primary prevention of VTE. SEARCH METHODS For this update the Cochrane Peripheral Vascular Diseases (PVD) Group Trials Search Co-ordinator searched the Specialised Register (last searched February 2014) and CENTRAL (2014, Issue 1). SELECTION CRITERIA Randomised controlled trials (RCTs) that assessed statins in the primary prevention of VTE were considered. The outcomes we evaluated were the rates of VTE, cardiovascular and cerebrovascular events, death and adverse events. Two authors (L Li, JH Tian) independently selected RCTs against the inclusion criteria. Disagreements were resolved by discussion with a third author (KH Yang). DATA COLLECTION AND ANALYSIS Data extraction was independently carried out by two authors (L Li, JH Tian). Disagreements were resolved by discussion with a third author (PZ Zhang). Two authors (L Li, JH Tian) independently assessed the risk of bias according to a standard quality checklist provided by the PVD Group. MAIN RESULTS For this update we included one RCT with 17,802 participants that assessed rosuvastatin compared with placebo for the prevention of VTE. The quality of the evidence was moderate because of imprecision, as the required sample size for the outcomes of this review was not achieved. Analysis showed that when compared with placebo rosuvastatin reduced the incidence of VTE (odds ratio (OR) 0.57, 95% confidence interval (CI) 0.37 to 0.86) and deep vein thrombosis (DVT) (OR 0.45, 95% CI 0.25 to 0.79), the risk of any (fatal and non-fatal) myocardial infarction (MI) (OR 0.45, 95% CI 0.30 to 0.69), and any (fatal and non-fatal) stroke (OR 0.51, 95% CI 0.34 to 0.78). There was no difference in the incidence of pulmonary embolism (PE) (OR 0.77, 95% CI 0.41 to 1.46), fatal MI (OR 1.50, 95% CI 0.53 to 4.22), fatal stroke (OR 0.30, 95% CI 0.08 to 1.09) or death after VTE (OR 0.50, 95% CI 0.20 to 1.24). The incidence of any serious adverse events was no different between the rosuvastatin and placebo groups (OR 1.07, 95% CI 0.95 to 1.20). AUTHORS' CONCLUSIONS Available evidence showed that rosuvastatin was associated with a reduced incidence of VTE, but the evidence was limited to a single RCT and any firm conclusions and suggestions could be not drawn. Randomised controlled trials of statins (including rosuvastatin) are needed to evaluate their efficacy in the prevention of VTE.
