[Prevalence of potential drug-drug interactions in ambulatory patients with statin therapy].

AIM: To asses the prevalence of potentially critical drug-drug interactions (DDIs) in outpatients treated with a statin. PATIENTS/METHODS: Data of patients (e.g. age, sex, comorbidities, individual statin, number of drugs, number of diagnoses) were collected from 242 Swiss practitioners. The medication was screened electronically for potentially critical DDIs. RESULTS: We included 2742 statin-treated patients (mean age 65.1 +/- 11.2 [SD] years, 3.2 +/- 1.6 diagnoses, 4.9 +/- 2.4 drugs prescribed) from the German (53.3%), French (36%) or Italian speaking (10.7%) part of Switzerland. Of those, 401 (14.6%) had a total of 591 potentially severe DDIs; 190 patients (6.9%) had potential statin DDIs, 288 (10.5%) potential non-statin DDIs, mainly due to pharmacodynamic mechanisms. The prevalence of potential DDIs was similar between regions, except for a trend for a higher prevalence of drug-statin interactions in the French-speaking part. The number of drugs per patient and a diagnosis of arrhythmia or heart failure were identified as risk factors for DDIs. CONCLUSIONS: Drug combinations with potentially severe DDIs are common in patients treated with statins due to pharmacotherapy of their co-morbidities. Special attention in this specific population should be drawn on patients with polypharmacy and those with drug treatments for arrhythmia or heart failure.

Therapy insight: Potential of statins for cancer chemoprevention and therapy.

The 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, also known as statins, are commonly prescribed medications that lower serum cholesterol and decrease cardiac morbidity and mortality. These agents inhibit the rate-limiting step of the mevalonate pathway, an effect that influences cholesterol homeostasis and other diverse cellular functions. Preclinical data suggest statins have pleiotropic antineoplastic effects in a variety of tumors, but clinical studies have provided conflicting data regarding whether statins may increase or decrease the risk of cancer. Abnormal cholesterol metabolism in cancer is poorly understood but should be considered when evaluating the antineoplastic effects of statins. Emerging evidence suggests that atherosclerosis and cancer have similar underlying molecular mechanisms, both having lipid abnormalities and a pro-inflammatory phenotype. Like nonsteroidal anti-inflammatory agents, statins target lipid metabolism, have significant anti-inflammatory effects, and can influence cardiovascular mortality. Recent studies show that statins may have chemopreventive effects and may complement cytotoxic chemotherapy or radiotherapy as a biologic response modifier in established cancer, but current data do not support their use as monotherapy. The preclinical data supporting anticancer activity, their additional health benefits, and the safety and relative low cost of statins compared to other 'targeted' agents currently under development all favor conducting prospective clinical trials of these drugs in cancer chemoprevention and therapy.

Mutual amplification of apoptosis by statin-induced mitochondrial stress and doxorubicin toxicity in human rhabdomyosarcoma cells.

Besides their cholesterol-lowering effect, 3-hydroxy-3-methyl-glutaryl-CoA reductase inhibitors (statins) show antiproliferative behaviour, which has been suggested as a promising anticancer strategy. However, the signalling cascades leading to statin-induced death of cancer cells are poorly characterized. Here we show that statins activate the mitochondrial pathway of apoptosis in rhabdomyosarcoma RD cells via translocation of Bax from the cytosol to mitochondria. The prototypical representative of statins, simvastatin, induced consecutive activation of caspase 9 and 3 in a concentration-dependent manner. The permeability transition pore inhibitor bongkrekic acid was capable of completely preventing simvastatin-induced caspase 9 and 3 activity, corroborating the mitochondrial pathway of apoptosis as the sole mechanism of statin action. Alternative pathways via death receptors, that is, caspase 8 or calpain activation, were not triggered by simvastatin. Simvastatin-treated RD cells could be completely rescued from apoptosis by the co-application of mevalonic acid, indicating that deprivation of cholesterol precursors is essential for statin-induced apoptosis. However, pretreatment with subthreshold concentrations of simvastatin was sufficient to augment doxorubicin toxicity via the mitochondrial apoptotic machinery. Moreover, the presence of doxorubicin increased the potency of simvastatin to trigger caspase activation. Taken together, these data highlight the therapeutic anticancer potential of statins and their additivity and mutual sensitization, in combination with doxorubicin in human rhabdomyosarcoma cells.

Direct comparison of dietary portfolio vs statin on C-reactive protein.

BACKGROUND: 3-Hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) markedly reduce serum cholesterol and have anti-inflammatory effects. The effect of cholesterol-lowering diets on inflammatory biomarkers is less well known. OBJECTIVE: To compare the efficacy of a dietary combination (portfolio) of cholesterol-lowering foods vs a statin in reducing C-reactive protein (CRP) as a biomarker of inflammation linked to increased cardiovascular disease risk. METHODS: In all, 34 hyperlipidemic subjects completed three 1-month treatments as outpatients in random order: a very low-saturated fat diet (control); the same diet with 20 mg lovastatin (statin); and a diet high in plant sterols (1.0 g/1000 kcal), soy protein (21.4 g/1000 kcal), viscous fibers (9.8 g/1000 kcal), and almonds (14 g/1000 kcal) (portfolio). Fasting blood samples were obtained at weeks 0, 2, and 4. RESULTS: Using the complete data, no treatment reduced serum CRP. However, when subjects with CRP levels above the 75th percentile for previously reported studies (> 3.5 mg/l) were excluded, CRP was reduced similarly on both statin, -16.3 +/- 6.7% (n = 23, P = 0.013) and dietary portfolio, -23.8 +/- 6.9% (n = 25, P = 0.001) but not the control, 15.3 +/- 13.6% (n = 28, P = 0.907). The percentage CRP change from baseline on the portfolio treatment (n = 25) was greater than the control (n = 28, P = 0.004) but similar to statin treatment (n = 23, P = 0.349). Both statin and portfolio treatments were similar in reducing CRP and numerically more effective than control but only the change in portfolio was significant after the Bonferroni adjustment. CONCLUSIONS: A combination of cholesterol-lowering foods reduced C-reactive protein to a similar extent as the starting dose of a first-generation statin.

Statins inhibit the dimerization of beta-secretase via both isoprenoid- and cholesterol-mediated mechanisms.

We have previously reported that protein lipidation in the form of palmitoylation and farnesylation is critical for the production of Abeta (amyloid beta-peptide), the dimerization of beta-secretase and its trafficking into cholesterol-rich microdomains. As statins influence these lipid modifications in addition to their effects on cholesterol biosynthesis, we have investigated the effects of lovastatin and SIMVA (simvastatin) at a range of concentrations chosen to distinguish different cellular effects on Abeta production and beta-secretase structure and its localization in bHEK cells [HEK-293 cells (human embryonic kidney cells) transfected with the Asp-2 gene plus a polyhistidine coding tag] cells. We have compared the changes brought about by statins with those brought about by the palmitoylation inhibitor cerulenin and the farnesyltransferase inhibitor CVFM (Cys-Val-Phe-Met). The statin-mediated reduction in Abeta production correlated with an inhibition of beta-secretase dimerization into its more active form at all concentrations of statin investigated. These effects were reversed by the administration of mevalonate, showing that these effects were mediated via 3-hydroxy-3-methylglutaryl-CoA-dependent pathways. At low (1 microM) statin concentrations, reduction in Abeta production and inhibition of beta-secretase dimerization were mediated by inhibition of isoprenoid synthesis. At high (>10 microM) concentrations of statins, inhibition of beta-secretase palmitoylation occurred, which we demonstrated to be regulated by intracellular cholesterol levels. There was also a concomitant concentration-dependent change in beta-secretase subcellular trafficking. Significantly, Abeta release from cells was markedly higher at 50 microM SIMVA than at 1 microM, whereas these concentrations resulted in similar reductions in total Abeta production, suggesting that low-dose statins may be more beneficial than high doses for the therapeutic treatment of Alzheimer's disease.

Reduced incidence of new-onset diabetes mellitus after renal transplantation with 3-hydroxy-3-methylglutaryl-coenzyme a reductase inhibitors (statins).

Statins have anti-inflammatory effects, modify endothelial function and improve peripheral insulin resistance. We hypothesized that statins influence the development of new-onset diabetes mellitus in renal transplant recipients. The records of all previously non-diabetic adults who received an allograft in Toronto between January 1, 1999 and December 31, 2001 were reviewed with follow-up through December 31, 2002. All patients receiving cyclosporine or tacrolimus, mycophenolate mofetil and prednisone were included. New-onset diabetes was diagnosed by the Canadian Diabetic Association criteria: fasting plasma glucose > or =7.0 mmol/L or 2-h postprandial glucose > or =11.1 mmol/L on more than two occasions. Statin use prior to diabetes development was recorded along with other variables. Cox proportional hazards models analyzing statin use as a time-dependent covariate were performed. Three hundred fourteen recipients met study criteria, of whom 129 received statins. New-onset diabetes incidence was 16% (n = 49). Statins (p = 0.0004, HR 0.238[0.109-0.524]) and ACE inhibitors/ARB (p = 0.01, HR 0.309[0.127-0.750]) were associated with decreased risk. Prednisone dose (p = 0.0001, HR 1.007[1.003-1.010] per 1 mg/d at 3 months), weight at transplant (p = 0.02, HR 1.022[1.003-1.042] per 1 kg), black ethnicity (p = 0.02, HR 1.230[1.023-1.480]) and age > or =45 years (p = 0.01, HR 2.226[1.162-4.261]) were associated with increased diabetes. Statin use is associated with reduced new-onset diabetes development after renal transplantation.

The myopathy of statins.

Statins are first-line drugs for prevention and treatment of hypercholesterolemia and atherosclerotic disease. Despite the fact that statins are generally well tolerated and have a positive impact on human health, their myotoxic properties should keep physicians on alert. Mechanisms of statin-induced myopathy are still not fully understood. Phenotypic characteristics of patients, individual statin properties, and metabolic interaction with other drugs are important factors that may increase risk for statin myopathy. The lowest effective dose of statin should be used during treatment. Early recognition of myopathy and discontinuation of statin is critical in preventing serious sequelae such as rhabdomyolysis with all its complications.

Early statin therapy in acute coronary syndromes.

Patients who survive an acute coronary syndrome of unstable angina or myocardial infarction are at much higher risk of a recurrent event within the following year than patients with stable coronary syndromes. Statin therapy is justified for many of these patients, not only for long-term benefit but also to reduce the risk of recurrent events within weeks of the primary event. The mechanisms that underlie this benefit are probably related to improvements in endothelial function, a decrease in vascular inflammation, and reduced prothrombotic factors. The effects of statins may be mediated by cholesterol reduction, cholesterol-independent effects (particularly decreasing isoprenoids), and mechanisms that are independent of inhibiting 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase. Observational studies consistently show an early reduction in mortality with statin therapy started before discharge from hospital after an acute coronary syndrome. Several randomized controlled trials also support an early benefit of risk reduction from statins started during the hospital admission for an acute coronary syndrome. Early statin therapy is also related to improved compliance and use of statins several years after a coronary event. Thus, early statin therapy may improve both early and long-term secondary prevention efforts.

Nitric oxide (NO)-releasing statin derivatives, a class of drugs showing enhanced antiproliferative and antiinflammatory properties.

Inhibitors of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase, namely statins, exert pleiotropic actions beyond lipid-lowering effects. Their pharmacological activity on atherosclerotic plaque stability and vascular inflammation appears to be mediated, at least in part, by nitric oxide (NO). With the aim of enhancing the nonlipid-lowering properties of selected statins, we introduced a NO-releasing moiety into the structure of pravastatin (NCX 6550) and fluvastatin (NCX 6553). NO release was evaluated as nitrosylhemoglobin adduct formation by using EPR spectroscopy in rat blood. Both compounds produced a linear time-dependent increase in nitrosylhemoglobin formation, which is consistent with slow NO release kinetics. In PC12 cells, unlike their native statins, both compounds stimulated cGMP formation (NCX 6550, EC(50) = 2.3 +/- 0.2 microM; NCX 6553, EC(50) = 2.7 +/- 0.2 microM). Moreover, NCX 6550 potently inhibited cell proliferation in rat aortic smooth muscle cells (IC(50) = 2.2 +/- 0.3 microM) with a mechanism that involved both the polyamine and HMG-CoA reductase signaling pathways. Hence, mevalonate or putrescine partially reverted the effects of NCX 6550 and their combination was fully effective. In RAW 264.7 murine macrophage cells stimulated with lipopolysaccharide (1 microg/ml), NCX 6550, but not pravastatin, significantly decreased inducible NO synthase and cyclooxygenase-2 protein expression as well as nitrite accumulation. All together, the data show that the previously undescribed NO-releasing statins retain HMG-CoA reductase inhibitory activity and release bioactive NO slowly. Among the additional properties, compared with native statins, the NO-releasing statins show enhanced antiinflammatory effects. Thus, NO-releasing statins represent an interesting class of drugs having potential in the therapy of disorders associated with endothelial dysfunction and vascular inflammation.

Statins cause intracellular accumulation of amyloid precursor protein, beta-secretase-cleaved fragments, and amyloid beta-peptide via an isoprenoid-dependent mechanism.

The use of statins, 3-hydroxy-3-methylglutaryl-CoA reductase inhibitors that block the synthesis of mevalonate (and downstream products such as cholesterol and nonsterol isoprenoids), as a therapy for Alzheimer disease is currently the subject of intense debate. It has been reported that statins reduce the risk of developing the disorder, and a link between cholesterol and Alzheimer disease pathophysiology has been proposed. Moreover, experimental studies focusing on the cholesterol-dependent effects of statins have demonstrated a close association between cellular cholesterol levels and amyloid production. However, evidence suggests that statins are pleiotropic, and the potential cholesterol-independent effects of statins on amyloid precursor protein (APP) metabolism and amyloid beta-peptide (A beta) genesis are unknown. In this study, we developed a novel in vitro system that enabled the discrete analysis of cholesterol-dependent and -independent (i.e. isoprenoid-dependent) statin effects on APP cleavage and A beta formation. Given the recent interest in the role that intracellular A beta may play in Alzheimer disease, we analyzed statin effects on both secreted and cell-associated A beta. As reported previously, low cellular cholesterol levels favored the alpha-secretase pathway and decreased A beta secretion presumably within the endocytic pathway. In contrast, low isoprenoid levels resulted in the accumulation of APP, amyloidogenic fragments, and A beta likely within biosynthetic compartments. Importantly, low cholesterol and low isoprenoid levels appeared to have completely independent effects on APP metabolism and A beta formation. Although the implications of these effects for Alzheimer disease pathophysiology have yet to be investigated, to our knowledge, these results provide the first evidence that isoprenylation is involved in determining levels of intracellular A beta.

Interrelationship of free oxygen radicals and endothelial dysfunction--modulation by statins.

3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) are successfully used for the treatment of hypercholesterolemia and profoundly reduce cardiovascular morbidity and mortality in hypercholesterolemic patients. Endothelial dysfunction is the early state of atherosclerosis and predicts adverse cardiac events and mortality. Reduced nitric oxide (NO) bioactivity in the vascular wall, caused by increased free oxygen-radical generation and decreased NO production, seems to be an important underlying mechanism. It is well established that statins improve endothelial dysfunction in hypercholesterolemic patients. However, results from in vitro studies, animal experiments, and small clinical trials suggest that statins may improve vascular function after short-term treatment in hyper- and normocholesterolemic individuals. The underlying mechanisms may at least in part be related to the cholesterol-independent effects of statins on vascular cells. Cellular antioxidative properties of statins, leading to decreased oxidative stress and restoration of NO bioactivity, may be of special relevance for the improvement of vascular function. However, further studies and clinical intervention trials are required to clarify the clinical importance of the pleiotropic effects in humans and their contribution to the well-established clinical benefits of statins and to confirm a beneficial effect of statin therapy on endothelial dysfunction and cardiovascular events in normocholesterolemic patients.

VE-statin, an endothelial repressor of smooth muscle cell migration.

The recruitment and proliferation of smooth muscle cells and pericytes are two key events for the stabilization of newly formed capillaries during angiogenesis and, when out of control in the adult, are the main causes of arteriosclerosis. We have identified a novel gene, named VE-statin for vascular endothelial-statin, which is expressed specifically by endothelial cells of the developing mouse embryo and in the adult, and in early endothelial progenitors. The mouse and human VE-statin genes have been located on chromosome 2 and 9, respectively, they span >10 kbp and are transcribed in two major variants arising from independent initiation sites. The VE-statin transcripts code for a unique protein of 30 kDa that contains a signal peptide and two epidermal growth factor (EGF)-like modules. VE-statin is found in the cellular endoplasmic reticulum and secreted in the cell supernatant. Secreted VE-statin inhibits platelet-derived growth factor (PDGF)-BB-induced smooth muscle cell migration, but has no effects on endothelial cell migration. VE-statin is the first identified inhibitor of mural cell migration specifically produced by endothelial cells.

Statins, fibrates, and melanoma risk: a systematic review and meta-analysis.

BACKGROUND: Large randomized, controlled clinical trials of lovastatin and gemfibrozil for heart disease prevention have reported statistically significantly lower melanoma incidences in persons receiving these medications. Results of in vitro animal model and human case-control studies also suggest that statins and fibrates may reduce the risk of melanoma. METHODS: We performed a systematic review of trials that randomly assigned participants to receive statins or fibrates versus an alternative therapy for a minimum of 6 months. Trials were identified by searching five electronic databases and the reference lists of eligible publications. Unpublished data were solicited from trial investigators and pharmaceutical companies. A meta-analysis was performed using a fixed-effects model, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate pooled treatment effects. All statistical tests were two-sided. RESULTS: We obtained data on incident melanomas from 20 of 36 qualifying randomized controlled trials (12 statin trials and eight fibrate trials), with a total of 70,820 participants. A total of 127 melanomas occurred among the 39,426 participants in the statin trials (59 among the 19,872 statin group participants and 68 among the 19,554 control group participants). A total of 27 melanomas occurred among the 31,394 participants enrolled in the fibrate trials (seven among the 12,324 fibrate group participants and 20 among the 19,070 control group participants). Overall, incidence of melanoma was not statistically significantly associated with the use of either statins (OR = 0.87, 95% CI = 0.61 to 1.23) or fibrates (OR = 0.45, 95% CI = 0.20 to 1.01). In a subgroup analysis by drug, only lovastatin use (in one trial) was statistically significantly associated with lower incidence of melanoma (OR = 0.52, 95% CI = 0.27 to 0.99). CONCLUSIONS: These findings do not validate the possibility that statins or fibrates prevent melanoma.

Severe irritability associated with statin cholesterol-lowering drugs.

BACKGROUND: As use of a drug becomes widespread, the full spectrum of its effects becomes clearer. Although a link has been suggested between low or lowered cholesterol and irritability/aggression, less is known about possible links between irritability and statins. AIM: To assess the possible connection of statin usage to severe irritability. DESIGN: Case series. METHODS: Six patients referred or self-referred with irritability and short temper on statin cholesterol-lowering drugs completed a survey providing information on character of behavioural effect, time-course of onset and recovery, and factors relevant to drug adverse effect causality. RESULTS: In each case the personality disruption, once evident, was sustained until statin use was discontinued; and resolved promptly with drug cessation. In four patients, re-challenge with statins occurred, and led to recrudescence of the problem. All patients experienced other recognized statin adverse effects while on the drug. Manifestations of severe irritability included homicidal impulses, threats to others, road rage, generation of fear in family members, and damage to property. DISCUSSION: Case series invariably raise more questions than they can answer. These case reports suggest that severe irritability may occur in some statin users. Although this adverse effect may be rare, potentially life-threatening adverse effects of drugs must be taken seriously.

Improved postoperative outcomes associated with preoperative statin therapy.

Statin therapy is well established for prevention of cardiovascular disease. Statins may also reduce postoperative mortality and morbidity via a pleiotropic (non-lipid-lowering) effect. The authors conducted a meta-analysis to determine the influence of statin treatment on adverse postoperative outcomes in patients undergoing cardiac, vascular, or noncardiovascular surgery. Two independent authors abstracted data from 12 retrospective and 3 prospective trials (n = 223,010 patients). A meta-analysis was performed to evaluate the overall effect of preoperative statin therapy on postoperative outcomes. Preoperative statin therapy was associated with 38% and 59% reduction in the risk of mortality after cardiac (1.9% vs. 3.1%; P = 0.0001) and vascular (1.7% vs. 6.1%; P = 0.0001) surgery, respectively. When including noncardiac surgery, a 44% reduction in mortality (2.2% vs. 3.2%; P = 0.0001) was observed. Preoperative statin therapy may reduce postoperative mortality in patients undergoing surgical procedures. However, the statin associated effects on postoperative cardiovascular morbidity are too variable to draw any conclusion.

Debate: at what level of coronary heart disease risk should a statin be prescribed?

3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) are effective treatments for the primary and secondary prevention of coronary heart disease, but an outstanding issue is determining who should have such treatment. The benefit from treatment with statins appears to be proportional to the underlying risk of coronary heart disease and independent of the factors increasing risk. Most benefit will therefore be achieved by treating people at increased risk of coronary heart disease. Statins reduce coronary morbidity even when the risk of coronary heart disease is relatively low (6% over 10 years), but reduction in all-cause mortality, the true measure of safety has been shown only when the risk of a major coronary heart disease event is 15% over 10 years or greater. At this level of risk patients appear willing to take treatment to gain the benefit expected from statin treatment, and the cost effectiveness of statin treatment is within the range accepted for other treatments. The major impediments to the systematic introduction of statin treatment at this level of risk are the very high overall cost and the large workload in countries like Britain, where the population risk of coronary heart disease is high. For this reason, recent British guidelines correctly advise statin treatment for secondary prevention and primary prevention when the 10 year coronary heart disease risk is 30% or greater as the first priority, moving to a lower coronary heart disease threshold for primary prevention only when resources permit.

Early initiation of statin therapy after a coronary event.

PURPOSE OF REVIEW: Despite improvements in the early management of acute coronary syndromes, the risk of major cardiovascular complications remains high. Lipid-modifying treatment with statins has the potential to further improve outcomes through improved endothelial function, antithrombotic and antiinflammatory actions. Statins are of proven benefit in patients with stable coronary heart disease. There has been speculation on potential mechanisms of benefit but, until recently, little data on the efficacy and safety of statins in the acute setting. Recent observational studies and randomized trials have addressed some of the questions regarding early initiation of statins in acute coronary syndromes. RECENT FINDINGS: Recent observational and randomized trials have shown that early commencement of statins in acute coronary syndromes is safe as early as 6 hours after the event and is likely to improve longer-term compliance. The current data are not sufficient to draw conclusions about the efficacy of statins early in the course of acute coronary syndromes. SUMMARY: Current management for acute coronary syndromes should include the commencement of statin therapy during initial hospital admission. This recommendation is based on safety and compliance data. More randomized trial evidence is required to determine whether early initiation will produce better outcomes than later initiation after an acute coronary event.

Cardiovascular disease with diabetes or the metabolic syndrome: should statins or fibrates be first line lipid therapy?

PURPOSE OF REVIEW: Subgroups with diabetes or with features of the metabolic syndrome have been increasingly highlighted in large clinical endpoint trials with lipid therapy. This review will focus on the results of trials with statins or fibrates and examine the strength of the evidence for major cardiovascular event reduction with each kind of therapy in these high-risk subgroups that typically have low-to-moderate levels of LDL cholesterol. RECENT FINDINGS: Of six statin trials in populations with moderately increased LDL cholesterol only one, the Heart Protection Study, has shown that statin therapy will significantly reduce the major coronary heart disease events of non-fatal myocardial infarction or coronary heart disease death in diabetes. None of these trials has shown that statins have a particular predilection for reducing cardiovascular events in individuals with higher levels of body weight or other features of the metabolic syndrome. There are far fewer trial data with fibrates than with statins. However, the Veterans Affairs High Density Lipoprotein Intervention Trial has shown that a fibrate can significantly reduce major cardiovascular events, most particularly coronary heart disease death, in those with diabetes as well as those without diabetes who have insulin resistance. Indeed, all fibrate trials show that this therapy appears to selectively benefit the individual with obesity and features of the metabolic syndrome. SUMMARY: Based principally on evidence from the Veterans Affairs High Density Lipoprotein Intervention Trial and the cumulative experience with statins, trial data would thus far suggest that the patient with a modest increase in LDL cholesterol who has diabetes or features of the metabolic syndrome might be likely to achieve more substantial cardiovascular benefit from fibrate than from statin therapy.
