Dyslipidemia is very common in diabetics and substantially increases the risk of fatal and non-fatal cardiovascular disease. Pharmacological therapy with 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors ('statins') is effective for dyslipidemia, but the cost and efficacy of individual therapies vary. Therefore, the interest in cost-effective pharmacologic interventions for the prevention of cardiovascular disease events in diabetics has increased. In this article, the literature pertaining to the epidemiology, cost and efficacy of statins in preventing cardiovascular disease in patients with type 2 diabetes mellitus, in both the primary and secondary prevention settings, is reviewed. Cost-effectiveness studies of statins in the diabetic population are detailed, along with recommendations for further research.

Recognition by the American Heart Association that obesity is a major modifiable risk factor for coronary heart disease has prompted health providers to take a more active role in obesity management. Obesity has long been known to accompany a host of chronic diseases, e.g., type II diabetes, hypertension, and dyslipidemia. We now recognize that obesity is itself a chronic disease with a complex etiology; like diabetes and hypertension, it is treatable with a similar chronic disease treatment model. Relatively modest weight loss confers disproportionate health benefits, improving a roster of risk factors. Diet, exercise, and behavior modification still compose the gold standard of treatment. If these measures fail, medication and surgery should be considered for appropriate patients. With current techniques, many patients can achieve realistic weight goals that can be maintained over the long term. Published management guidelines can now assist in integrating the practical applications of obesity-related research findings into everyday clinical practice.

An important complication of insulin-resistant states, such as obesity and type 2 diabetes, is an atherogenic dyslipidemia profile characterized by hypertriglyceridemia, low plasma high-density lipoproteins (HDL) cholesterol and a small, dense low-density lipoprotein (LDL) particle profile. The physiological basis of this metabolic dyslipidemia appears to be hepatic overproduction of apoB-containing very low-density lipoprotein (VLDL) particles. This has focused attention on the mechanisms that regulate VLDL secretion in insulin-resistant states. Recent studies in animal models of insulin resistance, particularly the fructose-fed hamster, have enhanced our understanding of these mechanisms, and certain key factors have recently been identified that play important roles in hepatic insulin resistance and dysregulation of the VLDL secretory process. This review focuses on these recent developments as well as on the hypothesis that an interaction between enhanced flux of free fatty acids from peripheral tissues to liver, chronic up-regulation of de novo lipogenesis by hyperinsulinemia and attenuated insulin signaling in the liver may be critical to the VLDL overproduction state observed in insulin resistance. It should be noted that the focus of this review is on molecular mechanisms of the hypertriglyceridemic state associated with insulin resistance and not that observed in association with insulin deficiency (e.g., in streptozotocin-treated animals), which appears to have a different etiology and is related to a catabolic defect rather than secretory overproduction of triglyceride-rich lipoproteins.

Diabetes mellitus is a major risk factor for the development of congestive heart failure (CHF). Diabetic cardiomyopathy has been acknowledged as a distinct disease entity that is an additional risk for diabetic patients to develop CHF, especially when they are affected by hypertension or epicardial coronary artery disease. Moreover, diabetic cardiomyopathy has been documented to lead to CHF even in the absence of other risk factors. As the combination of hypertension and diabetes has shown to be particularly detrimental, aggressive blood pressure control with a goal of less than 130/85 mm Hg is of critical importance. The first choice for pharmacologic treatment is angiotensin-converting enzyme inhibitors. Double- or triple-drug therapy is frequently required for good control. The increased risk of epicardial coronary artery disease in patients with diabetes warrants stringent treatment of dyslipidemia. If dilated cardiomyopathy with low ejection fraction is present, therapy with angiotensin-converting enzyme inhibitors, digoxin, diuretics, beta-blockers, and spironolactone (for patients with New York Heart Association class III to IV functional status) is indicated. If cardiac dysfunction consists predominantly of impaired diastolic function, heart rate control with a beta-blocker or a calcium antagonist is of particular importance. Control of blood glucose should be achieved, with hemoglobin A(1c) levels of less than 7%. Hyperinsulinemia should be avoided when possible; therefore, insulin-sensitizing agents are preferred over insulin-secretion-enhancing agents. Symptoms of CHF and acutely decompensated CHF should be treated no differently than nondiabetic patients. Care for patients with diabetes always includes lifestyle changes consisting of smoking cessation, decreasing obesity, regular exercise, and a heart-healthy diabetic diet.

Statins effectively lower LDL-cholesterol and some members of this class have been shown to reduce the risk of major cardiovascular events and total mortality in patients with or at risk for coronary heart disease. Statins are in general well tolerated. Withdrawal rates related to adverse events are low (< or =3%). The most common adverse events are mild gastrointestinal symptoms. Elevated serum transaminase levels occur infrequently (< or = 1.5%). These are generally asymptomatic, reversible and rarely require drug withdrawal. Statins do not cause adverse endocrine effects, do not alter glycemic control in diabetic patients, and do not increase cancer risk. Dose-related myopathy and/or rhabdomyolysis also occurs very rarely, although the risk is increased by concomitant administration of cyclosporine, niacin, fibrates, or by CYP3A4 isoenzyme inhibitors (e.g. erythromycin, systemic azole antifungal agents etc.) with statins metabolized by this isoenzyme. The pharmacokinetics of the individual statin should be considered in patients receiving polypharmacological treatments, to minimize the risk of unfavorable drug interactions. Atorvastatin is well tolerated in long-term treatment of dyslipidemia and is characterized by a safety profile similar to the other available statins.

Genetic, environmental, and metabolic risk factors are interrelated and contribute to the development of type 2 diabetes mellitus. A strong family history of diabetes mellitus, age, obesity, and physical inactivity identify those individuals at highest risk. Minority populations are also at higher risk, not only because of family history and genetics, but also because of adaptation to American environmental influences of poor dietary and exercise habits. Women with a history of gestational diabetes as well as their children are at greater risk for progressing to type 2 diabetes mellitus. Insulin resistance increases a person's risk for developing impaired glucose tolerance and type 2 diabetes. Individuals who have insulin resistance share many of the same risk factors as those with type 2 diabetes. These include hyperinsulinemia, atherogenic dyslipidemia, glucose intolerance, hypertension, prothrombic state, hyperuricemia, and polycystic ovary syndrome. Current interventions for the prevention and retardation of type 2 diabetes mellitus are those targeted towards modifying environmental risk factors such as reducing obesity and promoting physical activity. Awareness of risk factors for developing type 2 diabetes will promote screening, early detection, and treatment in high-risk populations with the goal of decreasing both microvascular and macrovascular complications.

Recent studies have proposed an association between hyperlipidemia and venous thromboembolism (VTE). We review the epidemiological evidence linking dyslipidemia with VTE and examine several possible underlying mechanisms. We discuss the possible role of HMG CoA reductase inhibitors (statins) in the prevention and treatment of VTE and suggest future directions for research.

Reducing elevated levels of low-density-lipoprotein cholesterol (LDL-C) significantly reduces the incidence of coronary heart disease (CHD) events and mortality in hypercholesterolemic patients. CHD risk reduction is proportional to LDL-C reduction. Despite this knowledge, many physicians are not applying existing treatment guidelines to the extent required to achieve target LDL-C levels. Target LDL-C levels are not achievable for most patients without drug therapy. Based on their lipid-lowering abilities, safety, and tolerability profiles, the HMG-CoA reductase inhibitors (statins) are the first-line pharmacotherapeutic agents for hypercholesterolemia. The ability of statins to reduce CHD events and total mortality in primary- and secondary-prevention patients also supports this assertion. For combined dyslipidemia, statin monotherapy is a reasonable initial approach in patients with moderate hypertriglyceridemia because statins effectively lower both LDL-C and triglycerides. Fibrates or niacin are effective therapies for severe hypertriglyceridemia. Resins are moderately effective in isolated hypercholesterolemia, and are a useful alternative to statins in pregnant women or patients with liver disease. For severe hyperlipidemia that does not respond to single drug therapy, combination drug therapy may be required. This article reviews the various manifestations of dyslipidemia and assesses the most efficacious treatments.

Although diabetes mellitus is predominantly a metabolic disorder, recent data suggest that it is as much a vascular disorder. Cardiovascular complications are the leading cause of death and disability in patients with diabetes mellitus. A number of recent reports have emphasized that many patients already have atherosclerosis in progression by the time they are diagnosed with clinical evidence of diabetes mellitus. The increased risk of atherosclerosis and cardiovascular complications in diabetic patients is related to the frequently associated dyslipidemia, hypertension, hyperglycemia, hyperinsulinemia, and endothelial dysfunction. The evolving knowledge regarding the variety of metabolic, hormonal, and hemodynamic abnormalities in patients with diabetes mellitus has led to efforts designed for early identification of individuals at risk of subsequent disease. It has been suggested that insulin resistance, the key abnormality in type II diabetes, often precedes clinical features of diabetes by 5-6 years. Careful attention to the criteria described for the cardiovascular dysmetabolic syndrome should help identify those at risk at an early stage. The application of nonpharmacologic as well as newer emerging pharmacologic therapies can have beneficial effects in individuals with cardiovascular dysmetabolic syndrome and/or diabetes mellitus by improving insulin sensitivity and related abnormalities. Early identification and implementation of appropriate therapeutic strategies would be necessary to contain the emerging new epidemic of cardiovascular disease related to diabetes.

Scavenger receptors recognize modified low-density lipoproteins (LDLs) such as acetylated LDL and oxidized LDL. Advanced glycation end products (AGE), which are generated through long-term exposure of proteins to glucose, also behave as active ligands for some scavenger receptors, including class A scavenger receptor (SR-A) and class B scavenger receptors such as CD36 and scavenger receptor, class B, type I (SR-BI). SR-BI, the first identified high-density lipoprotein (HDL) receptor, plays key roles in reverse cholesterol transport by promoting selective uptake of cholesteryl esters (CE) in HDL by hepatocytes, and cholesterol efflux of unesterified cholesterol from peripheral cells to HDL. Using Chinese hamster ovary cells overexpressing SR-BI (CHO-SR-BI cells), it was demonstrated that AGE-bovine serum albumin binds to SR-BI and inhibits selective uptake of HDL-CE by CHO-SR-BI cells as well as cholesterol efflux from CHO-SR-BI cells to HDL, suggesting potential roles of AGE in diabetic dyslipidemia and accelerated atherosclerosis in diabetes.
