Statin administration prior to ischaemic stroke onset and survival: exploratory evidence from matched treatment-control study.

In addition to their lipid-lowering effects, it has been speculated that statins may also have beneficial effects on cerebral circulation and brain parenchyma during ischaemic stroke and reperfusion. We hypothesized that patients who had taken statins prior to stroke onset may have a better survival rate at 1 month and during the follow-up period. We retrospectively studied consecutive ischaemic stroke patients admitted to an acute stroke unit and at least a month's follow-up. From these, we included those patients who, at admission, had reported the use of a statin prior to the stroke onset in the statin group (n = 205). Each patient in the statin group was matched with two patients who reported no statin use (n = 410). Using logistic regression and Cox proportional hazards models, we adjusted for variables that significantly differed between treatment groups or that independently predicted mortality. After adjusting for those variables, statin use was associated with reduced mortality at 1 month [odds ratio 0.24; 95% confidence interval (CI) 0.09-0.67] and during the follow-up period (hazard ratio 0.57; 95% CI 0.35-0.93). The use of statins prior to stroke onset is associated with improved stroke survival within this cohort study with matched controls.

Suboptimal statin adherence and discontinuation in primary and secondary prevention populations.

OBJECTIVES: To compare statin nonadherence and discontinuation rates of primary and secondary prevention populations and to identify factors that may affect those suboptimal medication-taking behaviors. DESIGN: Retrospective cohort utilizing pharmacy claims and administrative databases. SETTING: A midwestern U.S. university-affiliated hospital and managed care organization (MCO). PATIENTS: Non-Medicaid MCO enrollees, 18 years old and older, who filled 2 or more statin prescriptions from January 1998 to November 2001; 2258 secondary and 2544 primary prevention patients were identified. MEASUREMENTS: Nonadherence was assessed by the percent of days without medication (gap) over days of active statin use, a measurement known as cumulative multiple refill-interval gap (CMG). Discontinuation was identified by cessation of statin refills prior to the end of available pharmacy claims data. RESULTS: On average, the primary and secondary groups went without medication 20.4% and 21.5% of the time, respectively (P=.149). Primary prevention patients were more likely to discontinue statin therapy relative to the secondary prevention cohort (relative risk [RR], 1.24; 95% confidence interval [CI], 1.08 to 1.43). Several factors influenced nonadherence and discontinuation. Fifty percent of patients whose average monthly statin copayment was < US dollars 10 discontinued by the end of follow-up (3.9 years), whereas 50% of those who paid >US dollars 10 but US dollars 20 discontinued by 2.2 and 1.0 years, respectively (RR, 1.39 and 4.30 relative to <US dollars 10 copay, respectively). CONCLUSIONS: Statin nonadherence and discontinuation was suboptimal and similar across prevention categories. Incremental efforts, including those that decrease out-of-pocket pharmaceutical expenditures, should focus on improving adherence in high-risk populations most likely to benefit from statin use.

Hydroxymethylglutaryl-CoA reductase inhibitors in older persons with acute myocardial infarction: evidence for an age-statin interaction.

OBJECTIVES: To characterize the relationship between hydroxymethylglutaryl-CoA reductase inhibitors (statins) and outcomes in older persons with acute myocardial infarction (AMI). DESIGN: Observational study. SETTING: Acute care hospitals in the United States from April 1998 to June 2001. PARTICIPANTS: Medicare patients aged 65 and older with a principal discharge diagnosis of AMI (N=65,020) who did and did not receive a discharge prescription for statins. MEASUREMENTS: The primary outcome of interest was all-cause mortality at 3 years after discharge. RESULTS: Of 23,013 patients with AMI assessed, 5,513 (24.0%) were receiving a statin at discharge. Nearly 40% of eligible patients (n=8,452) were aged 80 and older, of whom 1,310 (15.5%) were receiving a statin at discharge. In a multivariable model taking into account demographic, clinical, physician and hospital characteristics, and propensity score, discharge statin therapy was associated with significantly lower 3-year mortality (hazard ratio (HR)=0.89 (95% confidence interval (CI)=0.83-0.96)). In an analysis stratified by age, discharge statins were associated with lower mortality in patients younger than 80 (HR=0.84, 95% CI=0.76-0.92) but not in those aged 80 and older (HR=0.97, 95% CI=0.87-1.09). CONCLUSION: Statin therapy is associated with lower mortality in older patients with AMI younger than 80 but not in those aged 80 and older, as a group. This finding questions whether statin efficacy data in younger patients can be broadly applied to the very old and indicates the need for further study of this group.

Re-assessing the relationship between cholesterol, statins and Alzheimer's disease.

This communication integrates the purported role of cholesterol and statins in Alzheimer's disease (AD) with recent data. Meta-analysis of association studies relevant to AD indicates that apolipoprotein (apo)E4 is the only cholesterol-related polymorphism that shows clear association with AD. This suggests that the effect of apoE4 on the pathophysiology of AD occurs via a mechanism that is not directly related to cholesterol, such as fibrillization of Abeta. Despite the lack of genetic association, cholesterol and statins clearly modulate amyloid precursor protein (APP) processing in cell culture and animal models. Statins appear to act by a pleiotropic mechanism, involving both cholesterol (via lipid rafts) and isoprenylation. The pleiotropic mechanism of statin action clarifies conflicting data from clinical studies, where statins exert an action on Abeta and AD that might be dose dependent because of actions on both cholesterol and isoprenylation. Reduced isoprenylation can also inhibit inflammation. Our own studies of brains from Alzheimer subjects +/- statins indicate that statins inhibit inflammation in humans but might not reduce cerebral Abeta load. These results suggest that the primary action of statins in humans with AD might be to reduce inflammation rather than decrease Abeta load.

Erectile dysfunction and statin treatment in high cardiovascular risk patients.

Erectile dysfunction (ED) has been associated with risk factors for atherosclerosis. Medications used for atherosclerosis have also been implicated in ED. The aim of this study is to investigate the relationship of erectile function to cardiovascular risk factors and specific drug therapies before and after 6 months of statin therapy. In this prospective observational study, International Index of Erectile Function (IIEF) scores were measured in 93 men attending cardiovascular risk clinics. Cardiovascular risk factors and drug therapies were assessed prior to initiation and after 6 months of statin therapy. Prior to statin therapy, the median IIEF score was 21 (range 0-25), and 57% had impairment of erectile function. After statin therapy, IIEF scores were reduced to 6.5 (range 0-25) (p < 0.001), and 22% experienced new onset ED. Before statin therapy no correlation was observed between IIEF score and any individual cardiovascular risk factor. After 6 months of statin therapy, correlations were observed between lower IIEF scores (r = 0.62; p < 0.001) and age and diabetes and weakly with smoking. Differences in dose, relative efficacy or relative lipophilicity of statin prescribed showed no correlation with change in IIEF score. This study suggests ED following statin therapy is more likely in patients with severe endothelial dysfunction due to established cardiovascular risk factors including age, smoking and diabetes.

A case control study of age related macular degeneration and use of statins.

AIMS: Age related macular degeneration (AMD) is the leading cause of blindness in industrialised countries. Previous studies have suggested that statins may have a protective effect against the disease; however, existing studies have had limited power to reliably detect or exclude an effect and have produced conflicting results. The authors assessed the risk of AMD associated with the use of statins. METHODS: Population based case control study using the United Kingdom General Practice Research Database. 18 007 people with diagnosed AMD were compared with 86 169 controls matched on age, sex, and general practice. The primary outcome was the odds ratio for the association between exposure to statins and AMD. RESULTS: The crude odds ratio for the association between any recorded exposure to statins and AMD was 1.32 (95% CI 1.17 to 1.48), but this reduced to 0.93 (95% CI 0.81 to 1.07, p=0.33) after adjustment for consultation rate, smoking, alcohol intake, body mass index, atherosclerotic disease, hyperlipidaemia, heart failure, diabetes mellitus, hypertension, use of other cardiovascular drugs, and use of fibrates. There was no evidence that the risk varied by dose of statin, duration of use, or that the risk varied for individual statins. CONCLUSION: In the short and medium term statin use is not associated with a decreased risk of AMD. Whether subgroups of patients with specific forms of AMD (particularly choroidal neovascularisation) benefit from statin therapy remains a possibility.

Use of statins in the secondary prevention of coronary heart disease: is treatment equitable?

OBJECTIVE: To investigate possible inequities in the use of statins for people with coronary heart disease according to a wide range of social and clinical factors. DESIGN AND SETTING: Cross sectional analysis of data from the Health Survey for England 1998, a population based survey. SUBJECTS: 760 adults with coronary heart disease. RESULTS: Only 19.9% of subjects with coronary heart disease were receiving lipid lowering drugs (151 of 760; 95% confidence interval (CI) 17.0% to 22.7%). The likelihood of receiving statins was greatly reduced for older age groups: compared with those aged less than 65 years, the odds of receiving statin treatment were 0.53 (95% CI 0.35 to 0.80) for subjects aged 65-74 years, and 0.11 (95% CI 0.06 to 0.21) for subjects aged 75 years and over. Statins were given less often to current cigarette smokers than to non-smokers (odds ratio 0.55, 95% CI 0.32 to 0.96), and to subjects with angina compared with those with a previous myocardial infarct (odds ratio 0.63, 95% CI 0.43 to 0.93). Lower levels of statin use were also seen with increasing time since diagnosis (p = 0.12). No clear associations were observed with social measures. CONCLUSIONS: Important inequalities were found in the use of statins among people with coronary heart disease, which could not be justified by evidence from the large statin trials. Proactive policies are required to ensure that the vast majority of (if not all) patients with coronary heart disease are receiving statins, regardless of age, sex, social class, smoking status, type of coronary heart disease, or time since diagnosis.

Statin treatment and reduced risk of pneumonia in patients with diabetes.

BACKGROUND: Recent prognostic studies have shown that previous treatment with statins is associated with a better outcome in patients admitted to hospital with pneumonia. Because of an increased risk of pneumonia in patients with diabetes, we assessed the effects of statin use on the occurrence of pneumonia in adult diabetic patients. METHODS: All patients with a diagnosis of diabetes (types 1 and 2) enlisted in the UK General Practice Research Database between 1 June 1987 and 21 January 2001 were included. A case-control study was performed with cases defined as patients with a first recorded diagnosis of pneumonia. For each case up to four controls were matched by age, sex, practice, and index date. Patients were classified as current users when the index date was between the start and end date of statin treatment. Conditional multiple logistic regression analysis was used to estimate the strength of the association between statin treatment and the occurrence of pneumonia. RESULTS: Statins were used in 1.1% of 4719 cases and in 2.1% of 15 322 matched controls (crude odds ratio (OR) 0.51, 95% CI 0.37 to 0.68). After adjusting for potential confounders, treatment with statins was associated with a significant reduction in the risk of pneumonia (adjusted OR 0.49, 95% CI 0.35 to 0.69). The association was consistent among relevant subgroups (cardiovascular diseases, pulmonary diseases) and independent of the use of other prescription drugs. CONCLUSIONS: The use of statins is associated with a considerable reduction in the risk of pneumonia in diabetic patients. In addition to lowering the risk of cardiovascular disease, statins may be useful in preventing respiratory infections.

The influence of statin use on breast density.

OBJECTIVE: To evaluate if 3-hydroxy-3-methylglutaryl CoA reductase reductase inhibitor use (statins) alters mammography measured breast density. METHODS: Cohort study of women ages 50 to 80 years with two mammography screenings. Changes in BI-RADS breast density between screenings was compared for nonusers, initiators, discontinuers, continuers, and any users of statins. RESULTS: Statin use was not associated with increases or decreases in breast density compared with nonusers after adjusting for age, body mass index, change in body mass index, hormone therapy use, and time between screenings. Cumulative days of statin use during the year before screening was not associated with changes in breast density in any of the groups of statin users. When hormone therapy users were excluded, any statin use was associated with an increase in breast density compared with nonusers (odds ratio, 1.2; 95% confidence interval, 1.0-1.5). CONCLUSIONS: We found no association between statin use and change in breast density in general, but statin use may be associated with increases in breast density among nonusers of hormone therapy.

Statins and blood coagulation.

The 3-hydroxy-3-methylglutaryl (HMG)-coenzyme A (CoA) reductase inhibitors (statins) have been shown to exhibit several vascular protective effects, including antithrombotic properties, that are not related to changes in lipid profile. There is growing evidence that treatment with statins can lead to a significant downregulation of the blood coagulation cascade, most probably as a result of decreased tissue factor expression, which leads to reduced thrombin generation. Accordingly, statin use has been associated with impairment of several coagulant reactions catalyzed by this enzyme. Moreover, evidence indicates that statins, via increased thrombomodulin expression on endothelial cells, may enhance the activity of the protein C anticoagulant pathway. Most of the antithrombotic effects of statins are attributed to the inhibition of isoprenylation of signaling proteins. These novel properties of statins, suggesting that these drugs might act as mild anticoagulants, may explain, at least in part, the therapeutic benefits observed in a wide spectrum of patients with varying cholesterol levels, including subjects with acute coronary events. The HMG-CoA reductase inhibitors (statins) have been shown to exhibit several vascular protective effects, including antithrombotic properties, that are not related to changes in lipid profile. Treatment with statins can lead to a significant downregulation of the blood coagulation cascade, most probably as a result of decreased tissue factor expression, which leads to reduced thrombin generation.

Statins decrease Toll-like receptor 4 expression and downstream signaling in human CD14+ monocytes.

OBJECTIVE: Anti-inflammatory effects of statins contribute to their clinical benefit. Molecular mechanisms underlying these effects have not been well explored. Because statins attenuate lipopolysaccharide (LPS) responsiveness, we hypothesized that part of the pleiotropic effects are mediated through innate immunity. METHODS AND RESULTS: Toll-like receptor (TLR) 4 expression and downstream signaling in CD14+ monocytes after incubation with simvastatin and atorvastatin were quantified via flow-cytometry, quantitative RT-PCR, kinase assay, and enzyme-linked immunosorbent assay. Incubation with intermediates/ inhibitors of the mevalonate pathway was used to identify the mode of statin action. Statin incubation resulted in a dose-dependent reduction of TLR4 expression (53+/-7.6% reduction compared with untreated monocytes; P<0.005), transcript levels (68+/-6.3%; P<0.002), decreased IRAK phosphorylation (37+/-8.3%; P<0.05), and LPS-induced IL-6, IL-12, tumor necrosis factor (TNF)-alpha, and B7-1 expression (P<0.05). Four weeks of treatment with atorvastatin significantly reduced TLR4 expression on circulating CD14+ monocytes by 36.2+/-4.2% (P<0.05). Effects of statins were reversed by mevalonate (P=0.57). Incubation with specific inhibitors of geranylgeranyltransferase (54+/-4.3%), farnesyltransferase (57+/-5.1%), or with clostridium-difficile toxin B (58+/-6.1%, P<0.01) imitated the statin effects. Whereas wortmannin and LY294002 inhibited the statin effect (P=0.27), incubation with a specific RhoA kinase inhibitor had no effect (P=0.57). CONCLUSIONS: Statins influence TLR4 expression and signaling via inhibition of protein geranylgeranylation and farnesylation. These observations imply interactions with innate immunity as one pleiotropic mechanism.

Statins but not angiotensin-converting enzyme inhibitors delay progression of aortic stenosis.

BACKGROUND: Recently, statins and angiotensin-converting enzyme inhibitors (ACEIs) have been shown to slow aortic valve calcium accumulation. Although several studies also suggest that statins may reduce the hemodynamic progression of aortic stenosis (AS), no data are available for ACEIs or the combination of both. METHODS AND RESULTS: A total of 211 consecutive patients (aged 70+/-10 years, 104 females) with native AS, defined by a peak velocity >2.5 m/s (valve area 0.84+/-0.23 cm(2), mean gradient 42+/-19 mm Hg), with normal left ventricular function and no other significant valvular lesion who were examined between 2000 and 2002 and who had 2 echocardiograms separated by at least 6 months were included. Of these, 102 patients were treated with ACEIs, 50 patients received statins, and 32 patients received both. Hemodynamic progression of AS was assessed and related to medical treatment. Annualized increase in peak aortic jet velocity for the entire study group was 0.32+/-0.44 m x s(-1) x y(-1). Progression was significantly lower in patients treated with statins (0.10+/-0.41 m x s(-1) x y(-1)) than in those who were not (0.39+/-0.42 m x s(-1) x y(-1); P<0.0001). This effect was observed both in mild-to-moderate and severe AS. ACEI use, however, did not significantly affect hemodynamic progression (P=0.29). Furthermore, ACEIs had no additional effect on AS progression when given in combination with statins (0.11+/-0.42 versus 0.08+/-0.43 m x s(-1) x y(-1) for combination versus statin only; P=0.81). Cholesterol levels did not correlate with hemodynamic progression either in the group receiving statins or in the group that did not. CONCLUSIONS: ACEIs do not appear to slow AS progression. However, statins significantly reduce the hemodynamic progression of both mild-to-moderate and severe AS, an effect that may not be related to cholesterol lowering.

Statins protect human aortic smooth muscle cells from inorganic phosphate-induced calcification by restoring Gas6-Axl survival pathway.

Vascular calcification is clinically important in the development of cardiovascular disease. It is reported that hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors (statins) inhibited vascular calcification in several clinical trials. However, the mechanism is poorly understood. Recently, it has been suggested that apoptosis is one of the important processes regulating vascular smooth muscle cell (VSMC) calcification. In this study, we investigated the effect of statins on VSMC calcification by testing their effect on apoptosis, focusing in particular on regulation of the survival pathway mediated by growth arrest-specific gene 6 (Gas6), a member of the vitamin K-dependent protein family, and its receptor, Axl. In human aortic smooth muscle cells (HASMC), statins significantly inhibited inorganic phosphate (Pi)-induced calcification in a concentration-dependent manner (reduced by 49% at 0.1 micromol/L atorvastatin). The inhibitory effect of statins was mediated by preventing apoptosis, which was increased by Pi in a concentration-dependent manner, and not by inhibiting sodium-dependent phosphate cotransporter (NPC) activity, another mechanism regulating HASMC calcification. Furthermore, the antiapoptotic effect of statins was dependent on restoration of Gas6, whose expression was downregulated by Pi. Restoration of Gas6 mRNA by statins was mediated by mRNA stabilization, and not by an increase in transcriptional activity. Suppression of Gas6 using small interfering RNA and the Axl-extracellular domain abolished the preventive effect of statins on Pi-induced apoptosis and calcification. These data demonstrate that statins protected HASMC from Pi-induced calcification by inhibiting apoptosis via restoration of the Gas6-Axl pathway.

Favorable outcome of ischemic stroke in patients pretreated with statins.

BACKGROUND AND PURPOSE: Statins may be beneficial for patients with acute ischemic stroke. We tested the hypothesis that patients pretreated with statins at the onset of stroke have less severe neurological effects and a better outcome. METHODS: We prospectively included consecutive patients with ischemic stroke of <24-hour duration. We recorded demographic data, vascular risk factors, Oxfordshire Classification, National Institutes of Health Stroke Scale (NIHSS) score, admission blood glucose and body temperature, cause (Trial of Org 10172 in Acute Treatment [TOAST] criteria), neurological progression at day 3, previous statin treatment, and outcome at 3 months. We analyzed the data using univariate methods and a logistic regression with the dependent variable of good outcome (modified Rankin Scale [mRS] 0 to 1, Barthel Index [BI] 95 to 100). RESULTS: We included 167 patients (mean age 70.7+/-12 years, 94 men). Thirty patients (18%) were using statins when admitted. In the statin group, the median NIHSS score was not significantly lower and the risk of progression was not significantly reduced. Favorable outcomes at 3 months were more frequent in the statin group (80% versus 61.3%, P=0.059 with the mRS; 76.7% versus 51.8%, P=0.015 with the BI). Predictors of favorable outcome with the BI were: NIHSS score at admission (OR: 0.72; CI: 0.65 to 0.80; P<0.0001), age (OR: 0.96; CI: 0.92 to 0.99; P=0.017), and statin group (OR: 5.55; CI: 1.42 to 17.8; P=0.012). CONCLUSIONS: Statins may provide benefits for the long-term functional outcome when administered before the onset of cerebral ischemia. However, randomized controlled trials will be required to evaluate the validity of our results.

Discontinuation of statin treatment in stroke patients.

BACKGROUND AND PURPOSE: Statins reduce the risk for myocardial infarctions and stroke which may in part depend on cholesterol-independent (pleiotropic) vasoprotective effects. Here, we review evidence to suggest that the abrupt discontinuation of statin medication exerts negative vascular effects in patients with acute vascular events. SUMMARY OF REVIEW: It is increasingly recognized that statins (HMG-CoA reductase inhibitors) exert rapid cholesterol-independent effects. Cessation of statin treatment confers overshoot activation of heterotrimeric G-proteins Rho and Rac causing production of reactive oxygen species and suppression of NO bioavailability. In humans, discontinuation of statin therapy leads to a proinflammatory, prothrombotic state with impaired endothelium function. In patients with acute coronary syndromes, abrupt discontinuation of statin therapy significantly increases morbidity and mortality, whereas in stable vascular patients discontinuation may be safe. Recent prospective data indicated that the cessation of statin medication in acute ischemic stroke patients confers a significantly higher likelihood of early neurological deterioration and poor outcome. CONCLUSIONS: We propose that in all acute ischemic stroke patients chronically treated with statins before the event, treatment should be continued and the patient should receive medication at the day of the stroke.

Risks associated with statin therapy: a systematic overview of randomized clinical trials.

BACKGROUND: Although statins reduce the risk of cardiovascular events, concerns about adverse effects may deter physicians from prescribing these agents. We performed a systematic overview of randomized statin trials to quantify the risks of musculoskeletal, renal, and hepatic complications associated with therapy. METHODS AND RESULTS: Major statin trials were identified by electronic search of the MEDLINE database from 1966 to December 2005. We included English language reports of adults with documented hyperlipidemia; double-blind, random allocation of > or = 100 patients to statin monotherapy versus placebo; and reports of myalgia, creatine kinase elevations, rhabdomyolysis, transaminase elevations, and discontinuation due to adverse events. Among 74,102 subjects enrolled in 35 trials (follow-up range, 1 to 65 months), statin therapy (excluding cerivastatin) did not result in significant absolute increases in risks of myalgias (risk difference/1000 patients [RD], 2.7; 95% CI, -3.2 to 8.7), creatine kinase elevations (RD, 0.2; 95% CI, -0.6 to 0.9), rhabdomyolysis (RD, 0.4; 95% CI, -0.1 to 0.9), or discontinuation due to any adverse event (RD, -0.5; 95% CI, -4.3 to 3.3). The absolute risk of transaminase elevations was significantly higher with statin therapy (RD, 4.2; 95% CI, 1.5 to 6.9). CONCLUSIONS: On the basis of data available from published clinical trials, statin therapy is associated with a small excess risk of transaminase elevations, but not of myalgias, creatine kinase elevations, rhabdomyolysis, or withdrawal of therapy compared with placebo. Further study is necessary to determine whether the results from these published clinical trials are similar to what occurs in routine practice, particularly among patients who are older, have more severe comorbid conditions, or receive higher statin doses than most patients in these clinical trials.

Statin use is associated with improved function and survival of lung allografts.

3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) are widely used antilipidemic agents that are also immunomodulatory. We evaluated possible effects of these agents after lung transplantation by comparing outcomes of 39 allograft recipients, who were prescribed statins for hyperlipidemia, with those of 161 contemporaneous control recipients who did not receive these drugs. Acute rejection (>or= Grade II) was less frequently found in the statin group (15.1 versus 25.6% of biopsies, p < 0.01). None of 15 recipients started on statins during postoperative Year 1 developed obliterative bronchiolitis, whereas the cumulative incidence of this complication among control subjects was 37% (p < 0.01). Total cellularity, as well as proportions of inflammatory neutrophils and lymphocytes, were significantly lower in bronchoalveolar lavages of statin recipients. Among double lung recipients, those taking statins had significantly better spirometry: FVC (80 +/- 2 versus 70 +/- 1%) and FEV1 (87 +/- 2 versus 70 +/- 1%), as percentages of predicted values, and absolute FEV1/FVC (83.4 +/- 1.2 versus 78.6 +/- 0.5) (all p < 0.01). The 6-year survival of recipients taking statins (91%) was much greater than that of control subjects (54%) (p < 0.01). These data suggest statin use may have substantial clinical benefits after pulmonary transplantation.

Statins and renal function.

Renal disease is often associated with an increased risk of vascular events. Moreover, an accelerated form of atherosclerosis commonly occurs in these patients. The reasons for these associations are not clearly defined but include the widespread presence of several established risk factors (eg, dyslipidemia, hypertension, and diabetes). Other predictors of atherosclerotic disease may also be abnormally elevated (eg, homocysteine, fibrinogen, and lipoprotein a). In addition, there is evidence that impaired renal function per se predicts vascular risk. Despite this high-risk background, the potential benefit of treatment with statins has not been widely investigated in these patients. The present review considers the evidence (experimental and clinical) that statins exert beneficial effects in patients with different types of renal disease. This includes improved renal function, decreased microalbuminuria, and a fall in blood pressure. Statins may also improve renal allograft survival. The potential mechanisms mediating these effects are considered. The interactions between statins and several risk factors that may be present in patients with impaired renal function are also considered. There is an urgent need to define the role of statins in these high-risk patients. Which is the statin of choice? This question is relevant because impaired renal function can interfere with statin pharmacokinetics. Furthermore, other drugs administered to these patients may cause serious interactions with statins.
