The risk of developing cardiovascular disease has recently been associated with a set of metabolic and physiological risk factors that include abdominal obesity, atherogenic dyslipidemia, hypertension, and elevated plasma glucose. The term most commonly used to describe this conglomeration of risk factors is the metabolic syndrome. Coronary heart disease risk is tripled in those individuals with this syndrome. Primary treatment focuses on weight reduction and physical activity to reduce risk factors and prevent the progression to cardiovascular disease. This article will review the definition, prevalence, pathogenesis, and treatment of the metabolic syndrome in women and will discuss the role of polycystic ovarian syndrome in relation to the metabolic syndrome.

Our understanding of the relationship between the atheroprotective activities of HDL and heterogeneity of HDL particles has advanced greatly. HDL particles are highly heterogeneous in structure, intravascular metabolism and antiatherogenic activity. In this review, we discuss new findings on the antiatherogenic properties of HDL particles. Small, dense HDL possesses potent antioxidative activity but this is compromised under conditions of atherogenic dyslipidemia. HDL functional deficiency frequently coincides with reductions in HDL-cholesterol concentration and alterations in HDL metabolism and structure. Formation of small, dense HDL particles with attenuated antiatherogenic activity can be mechanistically related to HDL enrichment in triglycerides and in serum amyloid A, depletion of cholesteryl esters, covalent modification of HDL apolipoproteins and attenuated antiatherogenic function of apolipoprotein AI. Low circulating levels of HDL cholesterol might, therefore, be associated with the defective functionality of small HDL particles of abnormal structure and composition. In common metabolic diseases, such as type 2 diabetes and metabolic syndrome, deficiency of HDL particle number and function favor accelerated atherosclerosis. Therapeutic normalization of the quantity, quality and biological activities of HDL particles thus represents a novel approach to attenuating atherosclerosis in dyslipidemic individuals with metabolic disease. Cholesteryl ester transfer protein inhibitors, nicotinic acid, reconstituted HDL and other HDL-raising agents are being investigated. Induction of selective increase in the circulating concentrations of small, dense HDL3 particles with increased antiatherogenic activity seems especially promising, particularly for therapy of atherogenic dyslipidemia.

The metabolic syndrome is a clustering of risk factors known to promote or increase the risk for development of cardiovascular disease. Recent estimates demonstrate that approximately one-third of the adult population of developed countries are characterized with metabolic syndrome by different definitions. Metabolic syndrome, even in the absence of diabetes, is associated with an increased risk of cardiovascular disease and total mortality, as well as an increased risk for the development of diabetes. Patients with diabetes are considered a cardiovascular risk equivalent, and warrant aggressive management of underlying risk factors to optimize prevention of cardiovascular disease. Initial evaluation of coronary heart disease risk involves global risk estimation using Framingham or other algorithms for risk prediction. Furthermore, consideration of screening for novel risk factors, such as C-reactive protein, as well as subclinical atherosclerosis (as assessed by carotid ultrasound, computed tomography or ankle-brachial index), can further refine the estimation of future cardiovascular disease risk. The presence of subclinical atherosclerosis or elevated levels of C-reactive protein can potentially modify recommended treatment goals for lipid and other cardiovascular risk factors.

The insulin resistance syndrome, which presents among its many facets obesity and type 2 diabetes mellitus, is a major risk factor for cardiovascular events. Thus, therapeutic guidelines recommend multifactorial treatment programs including, especially in the presence of type 2 diabetes, antiplatelet drugs. Few data, however, are available about the protective effect of antiplatelet therapy in both obese and type 2 diabetic patients. Furthermore, some reports showed a decreased sensitivity to the platelet antiaggregating effect of acetylsalicylic acid in diabetic patients. In the first part of this review, we focused our attention to alterations of platelets from insulin resistant subjects with or without type 2 diabetes, underlining that platelet hyperactivation is explained, at least in part, by: i) a reduced sensitivity to agents exerting an inhibitory modulation of platelet responses, ii) an altered intracellular milieu with elevated cytosolic Ca2+, iii) an enhanced thromboxane A2 synthesis, and iv) an increased number and/or function of GPIIb/IIIa complexes on platelet membranes. Furthermore, oxidative stress, which increases isoprostane production from arachidonic acid, may be involved in platelet hyperactivation, since isoprostanes activate platelets by interplaying with thromboxane receptors. These defects explain why antiplatelet therapy for both chronic atherosclerotic vascular disease and acute coronary syndromes should be specifically tailored in obese, insulin resistant subjects, especially in the presence of type 2 diabetes mellitus. Thus, in the second part of this review we carried out a critical overview of the clinical trials in subjects with metabolic syndrome and type 2 diabetes mellitus with or without macroangiopathy.

Metabolic syndrome affects approximately 44% of the US population over the age of 50 years. Although conflicting definitions exist, the syndrome is typically characterized by abdominal obesity, dyslipidemia, hypertension, and insulin resistance. Thus, it is a major risk factor for both coronary heart disease and type 2 diabetes. Furthermore, the risk of cardiovascular (CV) death is significantly increased in patients with diabetes and/or the metabolic syndrome. Although very few studies exist in patients with the metabolic syndrome, lifestyle changes and drug intervention targeted at the individual components have been shown to reduce the risk of developing diabetes and the incidence of CV disease in high-risk patients. Because many of the conventional antihypertensive drugs may affect the development of new onset diabetes, both positively and negatively, the choice of therapy is particularly important in this population. However, the long-term clinical trials to date have either not included new onset diabetes as a protocol end point or used various different criteria, making comparisons difficult. This review assesses the need for future research into metabolic syndrome and discusses whether clinical surrogates for CV end points, such as new onset diabetes, should be included in clinical trials of new drugs, new regimens, or new indications.

The environment of children has drastically changed in Europe during the last decades as reflected in unhealthy dietary habits and sedentary lifestyle. Nutrition obviously plays a part in the development of overweight in childhood. However, dietary factors and physical activity are also involved in the development of metabolic syndrome, type II diabetes, cardiovascular diseases, osteoporosis, and postural deformities like scoliosis, effects related in part to excessive weight gain. To stop the resulting epidemic of diet- and lifestyle-induced morbidity, efficient evidence-based approaches are needed. These issues are the focus of IDEFICS (Identification and prevention of dietary- and lifestyle-induced health effects in children and infants), a five-year project proposed under the sixth EU framework. The IDEFICS consortium comprises 25 research centres and SMEs across Europe. The planned prospective study will identify risk profile inventories for children susceptible to any of these disorders with emphasis on obesity and its co-morbid conditions. Genetic and non-genetic factors, psychosocial factors and social settings will be considered. The project will devise tailored prevention strategies that are effective, easy to implement and that account for the needs of different social groups. Population-based studies will investigate the impact of sensory perception and provide results concerning internal and external triggers of food choices and children's consumer behaviour. The ethical implications of a "right not to know" of genetic factors will be addressed. We will propose knowledge-based guidelines on dietary and lifestyle activities for health promotion and disease prevention in children for health professionals, stakeholders and consumers.

As combinations of drugs from different classes that have synergistic or additive effect and properties to cancel out each others' untoward hemodynamic and metabolic effects become more and more widely used, their use as first-line therapy for the treatment of newly diagnosed hypertensive patients is growing in popularity as well. The possibility to begin therapy with a fixed 2-drug combination may be preferable to starting with monotherapy followed by upward titration and addition of other agents. More and more combinations are coming out on the market and proving their effectiveness in randomized controlled trials and in large multicenter studies. One suggestion is the "polypill," a fixed combination of multiple agents that address various components of the metabolic syndrome and coexisting common risk factors in both high-risk patients with conditions requiring polypharmacy, and in healthy asymptomatic individuals.

A number of dietary components modulate the inflammatory response in humans, thereby affecting cardiovascular risk. As basic research provides a better understanding of the molecular mechanisms of vascular function regulation by nutrients, clinical investigation and outcome studies demonstrate the relevance of dietary factors to the prevention and treatment of vascular disease. Benefits of dietary interventions may be attributable to weight loss or to more specialized mechanisms in which inflammation is targeted directly. Available evidence indicates that dietary intervention should be an integral part of therapeutic approaches for treating conditions such as the metabolic syndrome and, ultimately, for the prevention of cardiovascular disease.

Scientific evidence continues to accumulate regarding fasting serum triglycerides as an independent risk factor for coronary heart disease. In response, the National Cholesterol Education Program has revised the acceptable level of fasting triglycerides from <200 mg/dL to <150 mg/dL. A significant percentage of Americans suffer from hypertriglyceridemia, and considering the expanding numbers of individuals who are physically inactive, overweight, and suffering from the metabolic syndrome, it is expected that these numbers will continue to rise over the next decade. Fortunately, nutraceutical and lifestyle options have been shown to substantially and consistently reduce this risk factor. This review will focus on management options for the hypertriglyceridemic patient with an emphasis on nicotinic acid, pantethine, fish oils (eicosapentaenoic and docosahexaenoic acids), and modified carbohydrate diets.

The metabolic syndrome has been referred to as a clustering of cardiovascular risk factors, including abdominal obesity, atherogenic dyslipidemia, increased blood pressure, insulin resistance, proinflammatory state, and a prothrombotic state. The metabolic syndrome has become one of the leading clinical issues discussed by physicians and the media, leading to increased public awareness to this potentially catastrophic multiplex risk factor for cardiovascular disease. With increasing prevalence in the United States, the metabolic syndrome has been equated to cigarette smoking as a contributing factor to premature cardiovascular heart disease and one of the underlying causes of type 2 diabetes. The identification and modification of the root causes, overweight/obesity, physical inactivity, and the closely associated condition, insulin resistance, needs to be one of the initial strategies that are addressed by the clinician.
