On a global scale, there is an increasing tendency for a more aggressive treatment of hypercholesterolemia. Minor effects of statins on brain cholesterol metabolism have been reported in some in vivo animal studies, and it seems that this is due to a local effect of the drug. We treated male ...

OBJECTIVES: This study examined whether intensive cholesterol-lowering therapy with statins in nonhypercholesterolemic patients is effective in improving echolucency of vulnerable plaques assessed by ultrasound with integrated backscatter (IBS) analysis. BACKGROUND: Atherosclerotic plaque stabilization is a promising clinical strategy to prevent cardiovascular events in patients with coronary artery disease (CAD). There ...

The early lesions of atherosclerosis begin in childhood, and are related to antecedent cardiovascular disease risk factors. Environmental and genetic factors such as diet, obesity, exercise, and certain inherited dyslipidemias influence the progression of such lesions. The identification of youth at risk for atherosclerosis includes an integrated assessment of these ...

Inhibitors of 3-hydroxy-3-methylglutaryl coenzymeA reductase are widely used in the management and prevention of cardiovascular disease. In addition to its major activity, plasma lipid lowering, statins have shown a wide spectrum of additional effects that may contribute to their benefits in the prevention of cardiovascular disease. Our objective was to ...

Use of statins for prevention of coronary heart disease is based on the decrease of serum cholesterol and LDL cholesterol. To better investigate the changes in lipid profile after statin treatment, we propose here to use an analysis of serum by proton nuclear magnetic resonance (NMR) spectroscopy associated with a ...

Serum cholesterol is a major risk factor for cardiovascular disease. Total cholesterol, LDL cholesterol and triglycerides are positively related to cardiovascular disease, while HDL cholesterol has an inverse relationship. Measurement of lipids is essential in individuals with established cardiovascular disease or type 2 diabetes, and may also be carried out ...

Statins have been the mainstay of lipid-lowering therapy since their introduction. However, as lower LDL cholesterol targets are sought, adjunct therapies are becoming increasingly important. Few patients reach new targets with statin monotherapy. We propose that the cholestanol:cholesterol ratio can be used to guide lipid-lowering therapy and result in greater ...

Despite a growing body of research on the benefit of combination drug therapy for dyslipidemia in the metabolic syndrome or diabetes mellitus, there are insufficient outcome data on the use of combination therapy as well as inadequate data to compare certain combination regimens. The focus of the therapeutic approach in ...

OBJECTIVES: We planned to carry out a pilot study to evaluate the efficacy and safety as an antihypercholesterolemic agent of a brand dietary supplement made of Monascus purpureus titrated extract, octacosanols and niacin on 111 Caucasian patients with low cardiovascular disease risk (<20% by Framingham algorithms), comparing them with the ...

How rapidly benefits accrue from nonstatin, lipid-lowering therapies is a 21st-century question posed to data collected in the 20th century. The 3 early dietary trials conducted in institutional settings where diet was strictly controlled demonstrate that, compared with a control diet, cholesterol-lowering diets reduce coronary event rates over several years. ...

Therapeutic strategies to prevent atherosclerotic plaque progression and achieve plaque stabilization involve 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA)-reductase inhibitors (statins) and renin-angiotensin system (RAS)-blockade, but studies investigating the potentially additive effects of a combined treatment strategy are rare. We hypothesised that the adjunction of atorvastatin with telmisartan or ramipril might achieve additional effects ...

Cardiovascular disease is the leading cause of death in the US and other industrialised societies. Rosuvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor, is the most efficacious lipid-lowering agent of the statin class. New guidelines and recent evidence-based studies confirm the benefit of intensive reduction of low-density lipoprotein cholesterol in terms ...

The authors investigated the effects of rosuvastatin, beyond its lipid-lowering activity, on several nonlipid metabolic variables, along with its safety and tolerability, in patients treated for primary hyperlipidemia. Patients (n = 55) with primary hyperlipidemia were open-label assigned to the recommended starting dose of rosuvastatin 10 mg/day, and serum metabolic ...

Elevated blood levels of low-density lipoprotein cholesterol (LDL-C) are associated with an increased risk for atherosclerotic coronary heart disease (CHD). Atorvastatin is a statin drug that inhibits 3-hydroxy-3-methyl-glutaryl coenzyme A reductase (the rate-limiting step of cholesterol production) and primarily lowers LDL-C levels. Atorvastatin has also been shown to significantly reduce ...

In the summer of 2004, an evidence-based update of the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) guidelines for management of hypercholesterolemia was published. This detailed assessment of 5 major clinical trials, published since the ATP III report in 2001, was designed to provide guidance for ...

BACKGROUND: The cardiovascular event rate in Japanese populations is strikingly lower than that in Caucasian populations and it has been postulated that this difference might be because of variations in atherosclerosis progression in patients with coronary artery disease (CAD). However, the rate of angiographically assessed progression and its response to ...

Use of plant stanols/sterols in forms that are sufficiently bioavailable for therapeutic effect should be a key element of maximal dietary therapy. This principle was recognized by National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) and has been amply confirmed by experimental studies in humans. Since the ...

Impairment of flow-mediated dilation (FMD) has been shown to be associated with hypercholesterolemia and hypertriglyceridemia and reduction of cholesterol and/or triglyceride levels can improve FMD. In hyperlipidemia the role of inflammatory substances on endothelial function requires further clarification. In patients with combined hyperlipidemia (n = 29), the capacity of FMD ...

This study investigated the effects of colesevelam hydrochloride (WelChol; Sankyo Pharma, Parsippany, NJ) and ezetimibe (Zetia; Merck/Schering Plough Pharmaceuticals, North Wales, PA), alone and in combination, for the treatment of hypercholesterolemia in patients who were intolerant to, or refused, HMG-Co-A reductase inhibitor (statin) therapy. Combination therapy with colesevelam HCl/ezetimibe resulted ...

Over the past two decades, statin-based intervention trials have conclusively shown that lowering low-density lipoprotein cholesterol (LDL-C) prevents cardiovascular disease and death. In response to these trials, the National Cholesterol Education Program has established and refined LDL-C goals in its Adult Treatment Panel (ATP) guidelines. In response to five new ...

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 ...

There is no doubt that lowering serum cholesterol levels reduces the risk of major coronary events. This evidence has led treatment guidelines to set progressively lower targets for low density lipoprotein cholesterol (LDL-C). However, despite widespread use of statins, substantial numbers of patients do not achieve the LDL-C goals. Using ...

BACKGROUND: The normalization of blood lipid profile has become an accepted method of primary and secondary prevention of vascular disease, with statins being the most popular group of medicines prescribed to lower cholesterol and LDL cholesterol levels. The failure of statins, administered in an appropriate dose, to maintain the optimal ...

Atherosclerosis and its complications still represent the major cause of death in developed countries. Statins have been described as the most potent class of drugs to reduce serum cholesterol levels. The effectiveness and rapidity of statin-induced decreases in coronary events led to the speculation that statins possess also cholesterol-independent effects. ...

BACKGROUND: Lowering high levels of low-density lipoprotein cholesterol (LDL-C) is the primary aim in the prevention of cardiac events. However, low levels of high-density lipoprotein cholesterol (HDL-C) are also associated with an increased risk of ischemic heart disease. Some patients have lower HDL-C during statin treatment than before the treatment. ...

Although low-density lipoprotein (LDL)-cholesterol lowering with the statins reduces the mortality and morbidity associated with coronary artery disease, considerable mortality and morbidity remains. Berberine upregulates the LDL receptor (LDLR) by a mechanism distinct from that of the statins, which involves stabilising the LDLR mRNA. In hamsters fed a high-fat and ...

While therapy with HMG-CoA reductase inhibitors, or statins, has provided the principal pharmacological innovation in the treatment of hypercholesterolemia in recent years, extensive use of these agents has shown that not all patients respond to them and that still greater reductions in low-density lipoprotein (LDL) cholesterol can further protect patients ...

Hyperlipidemia is an important risk factor for atherosclerosis. Hemorheological factors contribute to morbidity and mortality in patients with dyslipidemia. We evaluated the effects of 3 antihyperlipidemic drugs (pravastatin, atorvastatin, and fenofibrate), which have different mechanisms of action and different patterns of action on lipid profiles, on erythrocyte deformability and fibrinogen ...

The effects of atorvastatin (40 mg/day) versus placebo on fasting and postprandial plasma levels of high-sensitivity C-reactive protein (hs-CRP) and lipoprotein-associated phospholipase A2 (Lp-PLA2) were examined over 36 weeks in 84 patients who had coronary heart disease and low-density lipoprotein cholesterol levels >130 mg/dl and compared directly with the effects ...

The use of cholesterol targets in cardiovascular disease prevention means that we must have access to highly effective, well-tolerated drugs. Rosuvastatin is the most recently introduced member of the statin class and offers powerful low-density lipoprotein (LDL)-cholesterol lowering accompanied by sustained high-density lipoprotein (HDL)-cholesterol raising and triglyceride lowering. As the ...

Ezetimibe is intestinally active cholesterol absorption inhibitor used to reduce low-density lipoprotein-cholesterol levels. This case report describes a novel side effect with this agent: ezetimibe-induced hyperlipidaemia in a patient with statin intolerance and familial combined hyperlipidaemia. Ezetimibe therapy induced an asymptomatic 770% increase in triglycerides (TGs) (3.51-27.1 mmol/l) and a ...

BACKGROUND: As statin therapy has been reported to reduce antioxidants such as vitamin E and coenzyme Q10 and there are indications that this reduction may cause impairment of left ventricular function (LVF), we studied the influence of simvastatin on LVF and serum vitamin E and coenzyme Q10 levels in humans. ...

Patients with mixed dyslipidemias (increased LDL cholesterol and triglyceride as well as low HDL cholesterol levels) benefit from a combination of lipid-modifying drugs such as statins, niacin, fibrates and ezetemibe. However, safety, tolerability and cost are a concern in drug combination therapy. Dietary phytosterols reduce LDL cholesterol, and niacin or ...

STUDY OBJECTIVES: To determine the effects of atorvastatin on low-density lipoprotein cholesterol (LDL) particle size and C-reactive protein (CRP) concentrations in patients undergoing long-term hemodialysis. Another objective was to compare the effects of atorvastatin on lipoprotein profiles as determined by direct versus indirect assessment of lipoprotein composition. DESIGN: Randomized, parallel-group ...

HMG-CoA reductase inhibitors (statins) are widely prescribed and recommended as first-line therapy for most patients with hypercholesterolemia or established coronary heart disease. However, there is interpatient variability in lipid-lowering response to statins that is not explained by initial cholesterol levels and inadequate dosing alone. Genetic polymorphisms may contribute. This review ...

The 2004 update to the National Cholesterol Education Program guidelines goes farther than the 2001 version in suggesting an optional low-density lipoprotein cholesterol (LDL-C) goal of less than 70 mg/dL for patients at "very high risk." It recommends starting both diet and drug therapy in all patients at high or ...

Reduction of low-density lipoprotein cholesterol (LDL-C) with statin therapy is currently identified in treatment guidelines as the primary focus for patients with or at risk of coronary heart disease (CHD). Yet despite effective statin therapy there is still an unacceptably high residual coronary risk. A substantial proportion of patients with ...

Identification and management of dyslipidemia is an important element in the multi-factorial approach to prevent coronary heart disease. Diabetic dyslipidemia typically consists of elevated triglyceride, low high-density lipoprotein cholesterol, predominance of small, dense low-density lipoprotein (LDL) particles, and average LDL cholesterol (LDL-C). Lipid-lowering therapy has a beneficial effect on cardiovascular ...

OBJECTIVE: The purpose of this study was to assess the relationship between adherence to statin therapy and LDL cholesterol goal achievement in patients with diabetes and dyslipidemia. RESEARCH DESIGN AND METHODS: The records of patients being medically treated for dyslipidemia in a managed care diabetes program from January 2001 to ...

Inhibitors of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase are antilipidemic agents (statins) widely used for the prevention of cardiovascular diseases. Recent studies have suggested that the overall benefits of statin therapy cannot be accounted for solely by its antilipidemic effect. To obtain further insight into the mechanism of action of statins, we ...

Patients with combined hyperlipidemia (elevated triglyceride [TG] levels, elevated low-density lipoprotein [LDL] cholesterol, and multiple lipoprotein abnormalities) are at increased risk for coronary heart disease. We conducted a multicenter (in the United States), randomized, double-blind, active-controlled, 18-week study to determine if combination therapy with simvastatin plus fenofibrate is more effective ...

Familial hypercholesterolemia (FH) is characterized by the accumulation of excess cholesterol in tissues including the artery wall and tendons. We describe a patient with homozygous FH who presented with asymptomatic cholesterol granuloma of the brain. The patient's plasma low-density lipoprotein cholesterol level was remarkably responsive to combination hypolipidemic therapy with ...

Although statin therapy is a mainstay of lipid treatment, complementary effects of other cholesterol-lowering therapies modify the lipid panel and other aspects of coronary disease risk. These other therapies lower low-density lipoprotein cholesterol and triglycerides and/or raise high-density lipoprotein cholesterol, improve diabetic control, and modify other cardiovascular risks. Historically, combination ...

Ezetimibe reduces plasma low-density lipoprotein (LDL) cholesterol by blocking sterol absorption in enterocytes. The NPC1L1 gene product was recently identified as the molecular target for ezetimibe, although functional details are incomplete. We used the non-response phenotype of plasma LDL cholesterol to ezetimibe treatment to ascertain individuals who might have variant ...

BACKGROUND: Peritoneal sclerosis is a complication of peritoneal dialysis and results in ultrafiltration failure. It is related to chronic peritoneal injury due to dialysis solution content and recurrent peritonitis. Statins have anti-inflammatory properties which may be of value in modulating responses to injury. We evaluated the capacity of atorvastatin to ...

The critical importance of high-density lipoprotein cholesterol (HDL-C) as an independent and predictive factor for coronary heart disease (CHD) has been increasingly recognised in treatment guidelines for prevention and treatment of cardiovascular disease. The association of low HDL-C with an increased incidence of CHD implies a critical role for raising ...

3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors or "statin" medications are the most commonly prescribed therapy for lowering cholesterol. In use for over a decade, they have demonstrated both safety and tolerability across a broad range of patients. The ability to inhibit the biosynthesis of cholesterol and reduce low-density lipoprotein cholesterol levels ...

BACKGROUND: 3-Hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase inhibitors reduce serum cholesterol and are increasingly advocated in primary prevention to achieve reductions in LDL cholesterol. Newer dietary approaches combining cholesterol-lowering foods may offer another option, but these approaches have not been compared directly with statins in the same persons. OBJECTIVE: The objective was ...

The preventive effect of statins on coronary events is not only associated with the cholesterol-lowering effect of these drugs, but also various direct effects on the vascular wall, which include improvement of endothelial function, antioxidant activity, and anti-inflammatory activity. We investigated whether short-term statin therapy could improve arterial stiffness and ...

OBJECTIVE: To review the effects of lipid-lowering therapy on small-dense low-density lipoprotein cholesterol (sdLDL-C). DATA SOURCES: Literature was obtained from MEDLINE (1989-September 2004) and references of selected articles. Key search terms included small-dense LDL-C and lipid-lowering drug therapy. DATA SYNTHESIS: Statins, fibrates, and niacin have demonstrated favorable effects on sdLDL-C, ...
