The metabolic syndrome is a cluster of cardiovascular risk factors, including abdominal obesity, hypertension, dyslipidemia and insulin resistance, associated with increased risk of cardiovascular diseases and all cause mortality.
The purpose of the study was to assess the impact of the metabolic syndrome, and its individual components, on the risk of venous thromboembolism (VTE) in a prospective population-based study.
Individual components of the metabolic syndrome were registered in 6170 subjects aged 25-84 years in the Tromsø Study in 1994-1995, and first ever VTE events were registered until 1 September 2007.
The metabolic syndrome was present in 21.9% (1350 subjects) of the population. There were 194 validated first VTE events (2.92 per 1000 person-years) during a mean of 10.8 years of follow-up. Presence of metabolic syndrome was associated with increased risk of VTE (HR, 1.65; 95% CI, 1.22-2.23) in age- and gender-adjusted analysis. The risk of VTE increased with the number of components in the metabolic syndrome (P
AIM: Increased urinary albumin-excretion is a cardiovascular risk-factor. The cardiovascular risk of the metabolic syndrome (MetS) is debated. The aim of the present prospective, population-based study of non-diabetic individuals was to examine the association between low-grade urinary albumin-excretion, MetS, and cardiovascular morbidity and all-cause mortality. METHODS: 5215 non-diabetic, non-proteinuric men and women participating in the Tromsø Study 1994-1995 were included. Urinary albumin-creatinine ratio (ACR) was measured in three urine samples. The participants were categorized into four groups by the presence/absence of MetS (the International Diabetes Federation definition) and ACR in the upper tertile (>or=0.75 mg/mmol). RESULTS: Median follow-up time was 9.6 years for first ever myocardial infarction, 9.7 years for ischemic stroke and 12.4 years for mortality. High ACR (upper tertile)/MetS was associated with increased risk of myocardial infarction (hazard ratio (HR) 1.75; 95% confidence interval (CI): 1.30-2.37, por=0.75 mg/mmol was associated with cardiovascular morbidity and all-cause mortality independently of MetS. MetS was not associated with any end-point beyond what was predicted from its components. Thus, low-grade albuminuria, but not MetS, may be used for risk stratification in non-diabetic subjects.
The article is concerned with modern methods of assessment of arterial hypertension in patients with metabolic syndrome and characteristics of modern antihypertensive drugs and its combinations necessary for the elderly. The authors gave their own example of treatment of more than 2000 patients with arterial hypertension and metabolic syndrome.
Metabolic syndrome (MS) is a known risk factor for the development of osteoarthritis (OA). We asked whether the prevalence of MS varies across ethnicity among patients who undergo total knee arthroplasty for end-stage OA. In our population of 1460 patients undergoing primary knee arthroplasty, MS was defined as body mass index greater than 30 kg/m(2), diabetes, hypertension, and hypercholesterolemia. Among the 1334 white patients, 114 (8.5%) had MS as compared with 3 of 36 (8.3%) blacks and 18 of 90 (20%) Asians (P = .006) Adjusted analysis showed that those of Asian ethnicity had a 2.0 (95% confidence interval, 1.1-3.8; P = .03) times greater odds of MS as compared with those of other ethnicity. Metabolic syndrome is a risk factor for OA, and Asians demonstrate a greater prevalence of MS as compared with whites and blacks in this population.
We examined whether metabolic syndrome (MetS) predicts increased alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) levels in young adults, whether spontaneous recovery from MetS has a favorable effect on liver enzyme activities, and whether these enzymes contribute to the atherogenicity of MetS (assessed by carotid intima-media thickness (IMT)).
The study included 1,553 subjects (base-line age 31.5 ± 5.0 years). ALT and GGT were measured in 2007. MetS was diagnosed by the new Joint Interim Societies definition.
ALT and GGT levels were higher in subjects with MetS compared to those without in 2007. The association was independent of alcohol intake and BMI. In multivariable models adjusted for base-line age, LDL cholesterol, CRP, alcohol intake, and adiponectin, MetS in 2001 predicted increased ALT (ß ± SEM = 0.320 ± 0.062, P
In order to better understand the relations between different risk factors in the predisposition to type 2 diabetes, we present a Bayesian Network analysis of a large dataset, composed of three European population studies. Our results show, together with a key role of metabolic syndrome and of glucose after 2 hours of an Oral Glucose Tolerance Test, the importance of education, measured as the number of years of study, in the predisposition to type 2 diabetes.
To evaluate associations between binge-eating disorder (BED) and somatic illnesses and determine whether medical comorbidities are more common in individuals who present with BED and comorbid obesity.
Cases (n?=?850) were individuals with a BED diagnosis in the Swedish eating disorders quality registers. Ten community controls were matched to each case on sex, and year, month, and county of birth. Associations of BED status with neurologic, immune, respiratory, gastrointestinal, skin, musculoskeletal, genitourinary, circulatory, and endocrine system diseases were evaluated using conditional logistic regression models. We further examined these associations by adjusting for lifetime psychiatric comorbidity. Amongst individuals with BED, we explored whether comorbid obesity was associated with risk of somatic disorders.
BED was associated with most classes of diseases evaluated; strongest associations were with diabetes [odds ratio (95% confidence interval)?=?5.7 (3.8; 8.7)] and circulatory systems [1.9 (1.3; 2.7)], likely indexing components of metabolic syndrome. Amongst individuals with BED, those with comorbid obesity were more likely to have a lifetime history of respiratory [1.5 (1.1; 2.1)] and gastrointestinal [2.6 (1.7; 4.1)] diseases than those without comorbid obesity. Increased risk of some somatic disease classes in individuals with BED was not simply due to obesity or other lifetime psychiatric comorbidity.
The concepts of "cardiometabolic risk," "metabolic syndrome," and "risk stratification" overlap and relate to the atherogenic process and development of type 2 diabetes. There is confusion about what these terms mean and how they can best be used to improve our understanding of cardiovascular disease treatment and prevention. With the objectives of clarifying these concepts and presenting practical strategies to identify and reduce cardiovascular risk in multiethnic patient populations, the Cardiometabolic Working Group reviewed the evidence related to emerging cardiovascular risk factors and Canadian guideline recommendations in order to present a detailed analysis and consolidated approach to the identification and management of cardiometabolic risk. The concepts related to cardiometabolic risk, pathophysiology, and strategies for identification and management (including health behaviours, pharmacotherapy, and surgery) in the multiethnic Canadian population are presented. "Global cardiometabolic risk" is proposed as an umbrella term for a comprehensive list of existing and emerging factors that predict cardiovascular disease and/or type 2 diabetes. Health behaviour interventions (weight loss, physical activity, diet, smoking cessation) in people identified at high cardiometabolic risk are of critical importance given the emerging crisis of obesity and the consequent epidemic of type 2 diabetes. Vascular protective measures (health behaviours for all patients and pharmacotherapy in appropriate patients) are essential to reduce cardiometabolic risk, and there is growing consensus that a multidisciplinary approach is needed to adequately address cardiometabolic risk factors. Health care professionals must also consider risk factors related to ethnicity in order to appropriately evaluate everyone in their diverse patient populations.
Despite high diabetes rates among Canadian First Nations people, little is known about their cardiovascular disease risk. Our aim was to describe the apolipoprotein profile with respect to cardiovascular risk in a Canadian First Nation community.
In 2003, a representative sample of adult members of a Manitoba First Nation (N = 483) participated in a screening study for diabetes and diabetes complications. We assessed their cardiovascular risk factors.
Sixty percent of women were at increased cardiovascular risk because of low apolipoprotein A1 (apoA1) levels, compared with 35% of men. The proportion of women with low apoA1 levels decreased with age, but the proportion with low high-density lipoprotein levels remained stable across age groups. Both apoB and apoA1 were significantly associated with obesity when age, sex, diastolic blood pressure, homocysteine, diabetes, and insulin resistance were controlled for.
Apolipoprotein and lipid profiles in this First Nation population suggest high cardiovascular risk. Future research should characterize the lipoprotein particle size in this population.
