The metabolic syndrome is associated with increased risk of cardiovascular disease. However, the association between metabolic syndrome and atherosclerosis in hypercholesterolemic patients remains unknown. We examined the association between carotid atherosclerosis and metabolic syndrome definitions using the NCEP-ATPIII, International Diabetes Federation (IDF) and American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) definitions in 1782 subjects at risk of cardiovascular disease including 926 with hypercholesterolemia (LDL cholesterol > or =160 mg/dL; mean=203 mg/dL). Irrespective of definition, carotid intima-media thickness was significantly higher in both men and women diagnosed with the MetS compared to those without MetS. This relationship persists in males with hypercholesterolemia, independently of LDL cholesterol level. Regression analyses, both unadjusted and adjusted for traditional risk factors, indicate that in males the AHA/NHLBI definition, and in females the IDF definition are the strongest predictors of carotid atherosclerosis. These results highlight important gender differences that exist in the current clinical definitions of the metabolic syndrome, with regards to predicting early atherosclerotic lesions. In addition, this study shows that in males with hypercholesterolemia, MetS is independently associated with increased atherosclerosis, supporting screening for MetS among people at risk of CVD.

To investigate which of the three recently proposed definitions of the metabolic syndrome (MetS) is related to the excessive risk of ischaemic non-embolic stroke in elderly individuals, and thus may be more appropriate to implement in clinical practice. In a population-based case-control study of subjects aged older than 70 years (163 patients vs. 166 controls), we evaluated the association of first-ever acute ischaemic non-embolic stroke with the MetS defined by using recent definitions as proposed by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), the International Diabetes Federation (IDF) and the National Heart, Lung and Blood Institute/American Heart Association (NHLBI/AHA). By applying the NCEP ATP III, NHLBI/AHA and IDF definitions, the prevalence of MetS in the patient group was 46%, 57.1% and 69.9%, respectively, compared with 15.7%, 18.1% and 30.7% in the control group (p < 0.001 for all comparisons). After adjusting for multiple risk factors, the odds ratio (OR) for ischaemic stroke was 2.59 [95% confidence interval (CI): 1.24-5.42, p = 0.012] for NCEP ATP III-defined MetS and 3.18 (95% CI: 1.58-6.39, p = 0.001) for NHLBI/AHA-defined MetS. However, the association of IDF-defined MetS with ischaemic stroke was not significant (OR 1.18, 95% CI: 0.50-2.78, p = 0.71). The implementation of the IDF (unlike NCEP ATP III and NHLBI/AHA) MetS definition substantially increases the number of elderly subjects labelled as having MetS without contributing to the identification of those at high risk of stroke.

Metabolic syndrome is a condition characterized by the accumulation of multiple risk factors for atherosclerosis. Japanese-Americans in the U.S. have a more rapid and intense progression of atherosclerosis than native Japanese in Japan due to a westernization of their lifestyle. We investigated the prevalence of metabolic syndrome between 416 native Japanese (194 men and 222 women) in Hiroshima and 574 Japanese-Americans (217 men and 357 women) in Los Angeles, aged 30-89 years. According to the criteria proposed by the Japanese Society of Internal Medicine, the prevalence was 13.9 and 2.7% for native Japanese men and women, and 32.7 and 3.4% for Japanese-American men and women, respectively. According to the IDF or AHA/NHLBI criteria, the prevalence was 20.1 and 6.3%, and 38.7 and 4.5%, or 13.4 and 14.4%, and 30.9 and 27.7%, respectively. Thus, the prevalence of metabolic syndrome in men was significantly higher in Japanese-American than in native Japanese by all the three criteria. However, the prevalence in women was similar between native Japanese and Japanese-American by the Japanese and IDF criteria, whereas it was significantly higher in Japanese-American than in native Japanese by the AHA/NHLBI criteria. This report demonstrates that a westernization of lifestyle can increase the prevalence of metabolic syndrome among Japanese-Americans as compared to native Japanese.

The association between the severity of coronary artery disease (CAD) and metabolic syndrome (MS) as defined by recently proposed criteria remains unknown. Therefore, we investigated the association between the severity of CAD and MS based on four sets of criteria. The frequency of MS and the severity of CAD determined using the Gensini score (GS) were assessed in 656 consecutive patients who underwent elective coronary angiography for the first time. Using the various criteria, 25.4% of males and 25.6% of females fulfilled the NCEP-ATPIII criteria, 46.6% of males and 21.3% of females fulfilled the International Diabetes Federation (IDF) criteria, 44.0% of males and 41.9% of females fulfilled the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) criteria, and 42.5% of males and 18.8% of females fulfilled the Japanese definition. On multivariate analysis, MS defined according to the AHA/NHLBI criteria was related to an increased risk of extensive CAD in males [odds ratio (OR) 1.89, p=0.001]. MS defined according to the IDF criteria was associated with the highest risk for extensive CAD in females (OR 2.83, p=0.019). In conclusion, MS was found to be associated with the extent of CAD. However, gender-specific differences and MS definition-specific differences exist.

This study compared the prevalence of metabolic syndrome (MS) according to World Health Organization (WHO), National Cholesterol Education Program Third Adult Treatment Panel (NCEP-ATP III), International Diabetes Federation (IDF) and American Heart Association/ National Heart, Lung and Blood Institute (AHA/NHLBI) definitions, to evaluate how well the different classifications agreed. The study also compared their 10-year predicted risk of coronary heart disease (CHD) with the Framingham risk score (FRS). Some 886 women and 547 men aged 18-92 years were included in the study. Demographic and personal medical history data were obtained at interview. Four operational definitions of MS were used (those of the WHO, NCEP-ATP III, AHA/NHLBI and IDF). The prevalence of metabolic syndrome was found to be 26.4% (WHO criteria), 24.0% (NCEP-ATP III criteria), 41.9% (IDF criteria) and 37.2% (AHA/NHLBI criteria). According to the definition used, central obesity ranged from 41.9% to 75.1% and high blood pressure from 52.9% to 65.8%. Agreement between classifications ranged from 75.2% (kappa=0.47) to 90.4% (kappa=0.80) and was lower in males. The 10-year predicted risk of CHD by FRS was similar between the different definitions. IDF and AHA/NHLBI definitions resulted in a higher prevalence of MS than the NCEP-ATP III or WHO definition. Overall, however, good agreement was found between definitions, and the predicted 10-year of CHD risk was similar.

The objectives of this study were to determine the prevalence of metabolic syndrome (MS) and its component risk factors among Filipinos using three sets of criteria and to evaluate the association between MS and atherosclerotic cardiovascular disease and diabetes mellitus. The study utilised a multi-staged cluster sampling design. The prevalence of MS was found to be 11.9% by National Cholesterol Education Program/Adult Treatment Panel (NCEP/ATP III) criteria, 14.5% by International Diabetes Federation (IDF) criteria and 18.6% by NCEP/ATP III criteria modified by the American Heart Association/National Heart, Lung and Blood Institute (NCEP/ATP III-AHA/NHLBI) criteria. Low levels of high-density lipoprotein cholesterol (HDL-C) occurred in 60.2% of men and 80.9% of women. Abdominal obesity was noted in 17.7% of men and 35.1% of women. Blood pressure (BP) > or = 130/85 mmHg was seen in 33.3%, hypertriglyceridaemia in 20.6% and fasting blood sugar > or = 100 mg/dL (5.55 mmol/L) in 7.1%. Age-adjusted odds ratios showed that MS, by all three definitions, predisposed an individual to diabetes mellitus (DM) and stroke while MS by the IDF definition predisposed an individual to myocardial infarction (MI). Individuals with MS did not have a significant predisposition to angina and peripheral artery disease (PAD). Thus, the metabolic syndrome is common in Filipinos, with low HDL-C as the most prevalent component. The metabolic syndrome predisposes to diabetes mellitus and stroke, with a tendency to MI using the IDF criteria.

In recent years, atherosclerosis has become recognized as an inflammatory disease whose activity can be assessed by circulating biomarkers. Along with C-reactive protein (CRP), lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) may now be considered as a biomarker with sufficient accumulated evidence to support its application in clinical practice. Lp-PLA(2) is especially appealing because of its vascular specificity, which directly derives from its role in plaque pathophysiology. This article reviews the highlights of the >25 prospective epidemiologic studies now published on Lp-PLA(2) as a risk marker in primary or secondary prevention. These trials demonstrate generally consistent correlations between elevated Lp-PLA(2) levels and the increased risk for cardiovascular events, even after multivariable adjustment for traditional risk factors, with roughly a doubling of risk associated with upper quantile levels. Furthermore, Lp-PLA(2) as a risk predictor has been shown to be independent of and complementary to high-sensitivity CRP. These study results combined with recommendations from the American Heart Association/Centers for Disease Control (AHA/CDC) and the National Cholesterol Education Program III (NCEP III) suggest that Lp-PLA(2) might best be used in current clinical practice to refine risk prediction in those at intermediate cardiovascular risk. An increasingly prevalent group at intermediate risk shown to benefit from Lp-PLA(2) risk modification is the population with the cardiovascular metabolic syndrome, clinically identified as overweight patients with features of mixed dyslipidemia, dysglycemia, and hypertension. An additional application supported by these studies is further risk stratification of high- (often secondary-) risk patients into a group at very high risk, for whom a more aggressive target for low-density lipoprotein of <70 mg/dL (1 mg/dL = 0.02586 mmol/L) is now recommended as a reasonable therapeutic goal.

Lipodystrophy in HIV-infected patients (LDHIV) affects 40-50% of HIV-infected patients, but there are no data on its prevalence in Brazil. The aim of this study was to assess the LDHIV prevalence among HIV-infected adult Brazilian individuals, as well as to evaluate LDHIV association with cardiovascular risk factors and the metabolic syndrome (MS). It was included 180 adult HIV-infected outpatients consecutively seen in the Infectology Clinic of Universidade Estadual de Londrina. Anthropometric and clinical data (blood pressure, family and personal comorbidities, duration of HIV infection/AIDS, antiretroviral drugs used, CD4+ cells, viral load, fasting glycemia and plasma lipids) were obtained both from a clinical interview as well as from medical charts. LDHIV was defined as the presence of body changes self-reported by the patients and confirmed by clinical exam. MS was defined using the NCEP-ATPIII criteria, reviewed and modified by AHA/NHLBI. A 55% prevalence of LDHIV was found. Individuals with LDHIV presented a longer infected period since HIV infection, longer AIDS duration and longer use of antiretroviral drugs. In multivariate analysis, women (p=0.006) and AIDS duration >8 years (p<0.001) were independently associated with LDHIV. Concerning MS diagnostic criteria, high blood pressure was found in 32%, low HDL-cholesterol in 68%, hypertriglyceridemia in 55%, altered waist circumference in 17% and altered glycemia and/or diabetes in 23% of individuals. Abnormal waist and hypertriglyceridemia were more common in LDHIV-affected individuals. MS was diagnosed in 36%. In multivariate analysis, the factors associated with MS were: BMI >25 kg/m(2) (p<0.001), family history of obesity (p=0.01), indinavir (p=0.001) and age >40 years on HIV first detection (p=0.002). There was a trend to higher frequency of LDHIV among patients with MS (65% versus 50%, p=0.051). LDHIV prevalence among our patients (55%) was similar to previous reports from other countries. MS prevalence in these HIV-infected individuals seems to be similar to the prevalence reported on Brazilian non-HIV-infected adults.

Metabolic syndrome (MS) and "low grade" systemic inflammation (LGSI) are very common findings in the older population. Although MS and LGSI have been associated in adults, it is not known what is the real contribution of MS, and its single components, to LGSI in older persons, due to the potential confounding effect of comorbidity and aging. We investigated the relationship between increased C-reactive protein (CRP) plasma levels, a marker of LGSI, and MS in 1044 older (> or =65 years) community dwelling Italian individuals enrolled the InChianti study. Metabolic syndrome was defined by the NCEP-ATP III-AHA/NHLBI criteria. High sensitivity CRP (hs.CRP) levels were measured by enzyme-linked immunosorbent assay, and defined as high when >3mg/L. The overall prevalence of MS was 31%. The prevalence of high hs.CRP was 54.5% in subjects with, and 41.3% in those without MS (p<0.001). MS was associated with high hs.CRP levels after adjustment for age, gender, and comorbidity (OR: 1.93, 95% CI: 1.46-2.55). Compared to subjects with MS and no LGSI, individuals with MS and LGSI were characterized by higher waist circumference, BMI, and HOMA score. Multivariate logistic regression analysis confirmed the association between waist circumference and high hs.CRP levels in subjects with MS (waist circumference III vs. I tertile OR: 2.60, 95% CI: 1.79-3.77) independent of age, gender, and important confounding variables including comorbidity. Additional analyses, conducted with and without dichotomization of hs.CRP levels, confirmed the central role of waist circumference in the LGSI phenomenon, independent of gender and diagnosis of MS. We conclude that in older individuals, MS is associated with LGSI, but the association is mainly supported by a strong independent correlation between waist circumference and high hs.CRP levels. In the absence of this specific MS component, it seems that the contribution of MS to LGSI would be modest at best.

Limited information is available regarding risk of cardiovascular disease and trends for the metabolic syndrome in Asia. We examined the impact of the metabolic syndrome and its components on risk of cardiovascular disease among middle-aged Japanese according to four criteria. We followed 2,613 subjects from a rural Japanese community who participated in cardiovascular health examinations between 1990 and 1993. After 27,477 person-years of follow-up through 2003, there were 42 incidents of ischemic heart disease, 73 total strokes (54 ischemic and 18 hemorrhagic), and 115 total cases of cardiovascular disease. The metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII), American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI), International Diabetes Federation (IDF), and Japanese criteria. The multivariable hazard ratios (95%CI) associated with the metabolic syndrome based on NCEP-ATPIII criteria were 2.1 (1.1-4.0) for ischemic heart disease, 1.7 (1.0-2.7) for total stroke, 2.0 (1.2-3.5) for ischemic stroke, 1.1 (0.4-2.8) for hemorrhagic stroke, 2.0 (1.3-3.1) for ischemic cardiovascular disease, and 1.7 (1.2-2.5) for total cardiovascular disease. The population-attributable fractions of the metabolic syndrome based on NCEP-ATPIII criteria were 26-27% for ischemic heart disease and ischemic stroke and 20% for total cardiovascular disease. The metabolic syndrome based on AHA/NHLBI, IDF and Japanese criteria had weaker associations with risk of cardiovascular disease, and the association with risk of ischemic heart disease was not statistically significant. The metabolic syndrome based on NCEP-ATP III criteria predicted risks of ischemic heart disease, ischemic stroke and total cardiovascular disease, whereas that based on three other criteria predicted them less effectively.
