Obesity dyslipidemia

Patients with multiple risk factors, particularly those with diabetes, are at the greatest risk for IHD. Metabolic syndrome is a constellation of cardiovascular risk factors related to hypertension, abdominal obesity, dyslipidemia, and insulin...

Dyslipidemia is a common accompaniment of the lipodystrophy syndrome observed in HIV-infected patients. This syndrome presents as a combination of peripheral lipoatrophy and the metabolic syndrome (central adiposity, insulin resistance, and dyslipidemia). The term lipodystrophy syndrome was first used in two case reports to describe a clinical picture of subcutaneous fat wasting in the face and limbs of HIV infected patients treated with indinavir, reminiscent of the rare congenital lipodystrophy syndromes (138,139). In addition, benign symmetric lipomatoses on the trunk and neck were described. A systematic study of this syndrome in the Australian HIV cohort showed co-existence of peripheral lipoatrophy with abdominal visceral obesity, dyslipidemia, and insulin resistance in HIV-infected patients with or without treatment with protease inhibitors (140). 

Many experts believe that treating insulin resistance in the prediabetic state or after type 2 diabetes has become manifest may prevent or delay the development and progression of type 2 diabetes (111). Because insulin resistance is an underlying factor in P-cell failure and in other concomitants of type 2 diabetes such as obesity, dyslipidemia, and hypertension, early resolution of insulin resistance in the at-risk population may also reduce critical cardiovascular risk factors and thus prevent the development of late arterial and renal complications (115).

The association of insulin resistance with a clustering of cardiovascular risk factors including hyperinsuhnemia, hypertension, abdominal obesity, dyslipidemia, and coagulation abnormahties has been referred to by a variety of names including the insuhn resistance syndrome, the metabolic syndrome, the dysmetabolic syndrome, and the deadly quartet, to name a few. Since the description of the insulin resistance syndrome by Reaven in 1988, the number of associated factors has continued to grow.

Insulin resistance occurs when the normal response to a given amount of insulin is reduced. Resistance of liver to the effects of insulin results in inadequate suppression of hepatic glucose production insulin resistance of skeletal muscle reduces the amount of glucose taken out of the circulation into skeletal muscle for storage and insulin resistance of adipose tissue results in impaired suppression of lipolysis and increased levels of free fatty acids. Therefore, insulin resistance is associated with a cluster of metabolic abnormalities including elevated blood glucose levels, abnormal blood lipid profile (dyslipidemia), hypertension, and increased expression of inflammatory markers (inflammation). Insulin resistance and this cluster of metabolic abnormalities is strongly associated with obesity, predominantly abdominal (visceral) obesity, and physical inactivity and increased risk for type 2 diabetes, cardiovascular and renal disease, as well as some forms of cancer. In addition to obesity, other situations in which insulin resistance occurs includes...

Lifestyle changes should address other risk factors for cardiovascular disease including obesity, physical inactivity, insulin resistance, dyslipidemia, smoking cessation, and others. 

Factors that predispose an individual to IHD are listed in Table 4—2. Hypertension, diabetes, dyslipidemia, and cigarette smoking are associated with endothelial dysfunction and potentiate atherosclerosis of the coronary arteries. The risk for IHD increases two-fold for every 20 mm Hg increment in systolic blood pressure and up to eight-fold in the presence of diabetes.5,6 Physical inactivity and obesity independently increase the risk for IHD, in addition to predisposing individuals to other cardiovascular risk factors (e.g., hypertension, dyslipidemia, and diabetes).

Patients with metabolic syndrome are twice as likely to develop type 2 diabetes and four times more likely to develop CHD.3,11 These individuals are usually insulin resistant, obese, have hypertension, are in a prothrombotic state, and have atherogenic dyslipidemia characterized by low HDL cholesterol and elevated triglycerides, and an increased proportion of their LDL particles are small and dense.3... 

Non-alcoholic fatty liver disease begins with asymptomatic fatty liver but may progress to cirrhosis. This is a disease of exclusion elimination of any possible viral, genetic, or environmental causes must be made prior to making this diagnosis. Non-alcoholic fatty liver disease is related to numerous metabolic abnormalities. Risk factors include diabetes mellitus, dyslipidemia, obesity, and other conditions associated with increased hepatic fat.26... 

Insulin resistance has been associated with a number of other cardiovascular risks, including abdominal obesity, hypertension, dyslipidemia, hypercoagulation, and hyperinsulinemia. The clustering of these risk factors has been termed metabolic syndrome. It is estimated that 50% of the United States population older than 60 years of age have metabolic syndrome. The most widely used criteria to define metabolic syndrome were established by the National Cholesterol Education Program Adult Treatment Panel III Guidelines (summarized in Table 40-2). 

The risk of gout increases as the serum uric acid concentration increases, and approximately 30% of patients with levels greater than 10 mg/dL (greater than 595 pmol/L) develop symptoms of gout within 5 years. However, most patients with hyperuricemia are asymptomatic. Other risk factors for gout include obesity, ethanol use, and dyslipidemia. Gout is seen frequently in patients with type 2 diabetes mellitus and coronary artery disease, but a causal relationship has not been established. 

Because of comorbidity with diabetes, dyslipidemia, hypertension, and stroke, the presence of increased serum uric acid levels or gout should prompt evaluation for cardiovascular disease and the need for appropriate risk reduction measures. Clinicians should also look for possible correctable causes of hyperuricemia (e.g., medications, obesity, and alcohol abuse). 

The formation of atherosclerotic plaques is the underlying cause of coronary artery disease (CAD) and ACS in most patients. Endothelial dysfunction leads to the formation of fatty streaks in the coronary arteries and eventually to atherosclerotic plaques. Factors responsible for development of atherosclerosis include hypertension, age, male gender, tobacco use, diabetes mellitus, obesity, and dyslipidemia. 

ATP III recognizes the metabolic syndrome as a secondary target of risk reduction after LDL-C has been addressed. This syndrome is characterized by abdominal obesity, atherogenic dyslipidemia (elevated triglycerides, small LDL particles, low HDL cholesterol), increased blood pressure, insulin resistance (with or without glucose intolerance), and prothrom-botic and proinflammatory states. If the metabolic syndrome is present, the patient is considered to have a CHD risk equivalent. 

Obesity is associated with serious health risks and increased mortality. Central obesity reflects high levels of intraabdominal or visceral fat that is associated with the development of hypertension, dyslipidemia, type 2 diabetes, and cardiovascular disease.
