Dyslipidemic hypertension: distinctive features and cardiovascular risk in a prospective population-based study.

BACKGROUND: The prevalence, features, and risk of cardiovascular disease (CVD) in dyslipidemic hypertension (DH) was investigated in a prospective population-based study. Dyslipidemic hypertension was defined in terms of blood pressure, plasma triglycerides, and HDL-cholesterol consistent with the metabolic syndrome criteria of the National Cholesterol Education Program guidelines. High-normal or hypertensive values not meeting the other two criteria were designated as "simple hypertensives" (SH). METHODS: A sample of 2225 men and women and free of CVD at baseline were followed up for a mean of 4.1 years. The proportions of DH, SH, and normotensives were 16%, 37%, and 47%, respectively. All persons with DH had metabolic syndrome by definition, whereas metabolic syndrome formed 44.6% of SH. Fatal and nonfatal CVD, diagnosed by clinical findings and Minnesota coding of resting electrocardiograms, developed in 166 subjects. RESULTS: Compared to SH, sex- and age-standardized individuals with DH had significantly higher body mass index, apolipoprotein B, fasting insulin, glucose, and C-reactive protein levels, had higher prevalence of impaired fasting glucose and metabolic syndrome. Cox regression analysis revealed a 1.57-fold higher (confidence interval 1.08-2.28) hazard ratio (HR) for CVD in DH than in SH, after adjustment for sex, age, LDL-cholesterol, and smoking status. The sex- and age-adjusted HR of DH was furthermore 1.45-fold higher than the remaining subjects with metabolic syndrome (P = .096). Among persons with DH, age, presence of diabetes, and pulse pressure proved to be independent predictors for CVD. High LDL-cholesterol levels and fasting hyperinsulinemia were associated with borderline significantly elevated relative risks among dyslipidemic hypertensives. CONCLUSIONS: Dyslipidemic hypertension, prevailing in 1 of every 6 adults, implicates characteristic features, confers excess CVD risk compared to the remainder of hypertensives and carries half the attributable cardiovascular risk due to metabolic syndrome.

Serum uric acid is a determinant of metabolic syndrome in a population-based study.

BACKGROUND: Determination of serum uric acid concentrations and role in risk of metabolic syndrome (MS) were investigated in 1877 participants in a cross-sectional population-based study including a brief follow-up. METHODS: The MS was identified by modified criteria of the Adult Treatment Panel III, and coronary heart disease (CHD) by clinical findings and Minnesota coding of resting electrocardiograms. Uric acid concentrations were measured by the uricase method. RESULTS: Metabolic syndrome was present in 39.1% of the cohort. Linear regression analysis of uric acid levels in a model comprising 13 variables identified gender, waist girth, total cholesterol (TC), alcohol usage, triglycerides, log C-reactive protein (CRP), and log gamma-glutamyl transferase (GGT), and in women diuretic use and elevated blood pressure (BP), as significant independent covariates whereby the largest contribution (1.6 mg/dL) was generated by waist girth. Logistic regression analysis of serum uric acid for MS disclosed for the top versus the bottom tertile an odds ratio (OR) of 1.89 (95% confidence interval [CI]: 1.45-2.46) in men and women combined, after adjustment for sex, age, TC, log CRP, log GGT, alcohol, and diuretic drug use, presence of diabetes/impaired fasting glucose, elevated BP, and smoking status. This corresponded to an increase by 35% in MS likelihood for each 1 SD uric acid increment. This rate declined to a significant 15% by inclusion of waist girth into the model. The OR of uric acid concentrations for prevalent and incident CHD, adjusted for age, MS, smoking, and diuretic use, was not significant among women and only tended toward significance in men. CONCLUSIONS: Abdominal obesity is the main determinant of uric acid variance. An increment of 1 SD in serum uric acid levels are associated in both sexes with a 35% higher MS likelihood, independent of 10 risk factors related to MS. After adjustment for waist girth, a more modest but significant likelihood persists, which suggests that serum uric acid is a determinant of MS.

Impact of redefining acute myocardial infarction on incidence, management and reimbursement rate of acute coronary syndromes.

BACKGROUND: Although redefinition for acute myocardial infarction (AMI) has been proposed few years ago, to date it has not been universally adopted by many institutions. The purpose of this study is to evaluate the diagnostic, prognostic and economical impact of the new diagnostic criteria for AMI. METHODS: Patients consecutively admitted to the emergency department with suspected acute coronary syndromes were enrolled in this study. Troponin T (cTnT) was measured in samples collected for routine CK-MB analyses and results were not available to physicians. Patients without AMI by traditional criteria and cTnT > or = 0.035 ng/mL were coded as redefined AMI. Clinical outcomes were hospital death, major cardiac events and revascularization procedures. In-hospital management and reimbursement rates were also analyzed. RESULTS: Among 363 patients, 59 (16%) patients had AMI by conventional criteria, whereas additional 75 (21%) had redefined AMI, an increase of 127% in the incidence. Patients with redefined AMI were significantly older, more frequently male, with atypical chest pain and more risk factors. In multivariate analysis, redefined AMI was associated with 3.1 fold higher hospital death (95% CI: 0.6-14) and a 5.6 fold more cardiac events (95% CI: 2.1-15) compared to those without AMI. From hospital perspective, based on DRGs payment system, adoption of AMI redefinition would increase 12% the reimbursement rate [3552 Int dollars per 100 patients evaluated]. CONCLUSIONS: The redefined criteria result in a substantial increase in AMI cases, and allow identification of high-risk patients. Efforts should be made to reinforce the adoption of AMI redefinition, which may result in more qualified and efficient management of ACS.

Sex difference in development of diabetes and cardiovascular disease on the way from obesity and metabolic syndrome.

AIM: The objective of this study was to investigate sex-specific differences existing on the way from (abdominal) obesity and metabolic syndrome (MS) to type 2 diabetes mellitus (DM) and cardiovascular disease (CVD). METHODS: A population sample of 1974 men and women, representative of Turkish adults (mean age, 48 years), with normal glucose metabolism (GM) and free of CVD at baseline, was prospectively evaluated at a mean 4.1 years of follow-up. The term abnormal GM designated both DM and impaired fasting glucose (IFG). Metabolic syndrome was identified in 29% of men and 40% of women by the criteria of the National Cholesterol Education Program guidelines. Fatal and nonfatal CVD, diagnosed by clinical findings and Minnesota coding of resting electrocardiograms, developed in 121 subjects. RESULTS: The cohort was dichotomized by the presence or absence of MS and of obesity defined by a body mass index of 30 kg/m 2 or greater. Compared with the major female group with no obesity or MS, women with MS, regardless of the presence of obesity, predicted highly significantly the development of abnormal GM with relative risks exceeding 2, whereas no independent significant association was noted in men with MS. Similar divergence of sexes pertained to the prediction of diabetes. When age, smoking status, grade of physical activity, IFG, DM, and the 4 groups with obesity and MS were analyzed for the prediction of CVD by logistic regression, men with MS, regardless of the presence of obesity, predicted highly significantly CVD (with relative risks ranging from 2 to 4), but neither DM nor IFG contributed independently. Conversely, in women, abnormal GM predicted CVD independent of age, smoking status, and grade of physical activity, but the groups with obesity and MS failed to significantly contribute independently. CONCLUSIONS: In populations with prevalent MS, whereas women with normal GM are prone to DM within the context of MS and are exposed to CVD risk primarily by way of DM, men are prone to visceral adiposity, less susceptible to DM, and run CVD risk primarily by the intermediary of MS, largely independent of the DM component.

Mental health nursing students' relationships with the pharmaceutical industry.

INTRODUCTION: The medical profession's relationship with the pharmaceutical industry (PI) has come under increased scrutiny in recent years, however little is known on the subject in mental health nursing. AIMS: The study sought to investigate: (1) the frequency of contact between mental health nursing students and PI employees; (2) students' attitudes and beliefs about their relationship with the PI; (3) the range of 'gifts', promotional items and hospitality accepted or seen in clinical environments by students in a one year period; and (4) students' attitudes to 'gifts', promotional items and hospitality offered by the industry. METHOD: Employing a survey design, a 35-item questionnaire was distributed to 472 students at two universities in the UK. Data were analysed from 347 respondents by means of descriptive statistics and simple content analysis. RESULTS: The findings suggest that students have significant contact with the industry through one-to-one meetings with pharmaceutical representatives (PRs) and by attending events giving information on specific drugs or general mental health issues. Students also identified a number of benefits (e.g. receiving "up-to-date" information on new drugs) and problems (e.g. the potential influence exerted on practitioners to use their drugs) arising out of this contact. Most students (79.8%) had accepted some form of 'gift' from the industry but few (11.5%) believed it was unacceptable to do so. The presence of promotional items in the clinical environment was seen as advertising (84.4%) but few students (19.3%) believed clinical environment should be free of these items. Over half (57.1%) of the students believed that PRs did not always give unbiased information but thought that they and mental health nurses in general would be able to detect any bias. CONCLUSIONS: In parallel with medicine, the study has shown that the pharmaceutical industry has at least the potential to influence mental health nursing students. Within medicine this realisation has triggered a vigorous debate on how medical schools should respond to the promotional activities of the PI. We suggest this study goes some way to demonstrating there is a need for these issues to be debated in the education of mental health nurses.

Accuracy of coding for possible warfarin complications in hospital discharge abstracts.

BACKGROUND: Hospital discharge abstracts could be used to identify complications of warfarin if coding for bleeding and thromboembolic events are accurate. OBJECTIVES: To measure the accuracy of International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9CM) codes for bleeding and thromboembolic diagnoses. SETTING: University affiliated, tertiary care hospital in Ottawa, Canada. PATIENTS: A random sample of patients discharged between September 1999 and September 2000 with an ICD-9-CM code indicating a bleeding or thromboembolic diagnosis. METHODS: Gold-standard coding was determined by a trained chart abstractor using explicit standard diagnostic criteria for bleeding, major bleeding, and acute thromboembolism. The abstractor was blinded to the original coding. We calculated the sensitivity, specificity, positive, and negative predictive values of the original ICD-9CM codes for bleeding or thromboembolism diagnoses. RESULTS: We reviewed 616 medical records. 361 patients (59%) had a code indicating a bleeding diagnosis, 291 patients (47%) had a code indicating a thromboembolic diagnosis and 36 patients (6%) had a code indicating both. According to the gold standard criteria, 352 patients experienced bleeding, 333 experienced major bleeding, and 188 experienced an acute thromboembolism. For bleeding, the ICD-9CM codes had the following sensitivity, specificity, positive and negative predictive values [95% CI]: 93% [90-96], 88% [83-91], 91% [88-94], and 91% [87-94], respectively. For major bleeding, the ICD-9CM codes had the following sensitivity, specificity, positive and negative predictive values: 94% [91-96], 83% [78-87], 87% [83-90], and 92% [88-95], respectively. For thromboembolism, the ICD-9CM codes had the following sensitivity, specificity, positive and negative predictive values: 97% [94-99], 74% [70-79], 62% [57-68], and 98% [96-99], respectively. By selecting a sub-group of ICD-9CM codes for thromboembolism, the positive predictive value increased to 87%. CONCLUSION: In our centre, the discharge abstract could be used to identify and exclude patients hospitalized with a major bleed or thromboembolism. If coding quality for bleeding is similar in other hospitals, these ICD-9-CM diagnostic codes could be used to study population-based warfarin-associated hemorrhagic complications using administrative databases.

C-reactive protein and coronary heart disease in western Turkey.

C-reactive protein (CRP) has been recognized as a useful marker for coronary or cardiovascular risk in healthy subjects or patients with coronary heart disease (CHD) in industrialized societies. We assessed whether CRP could serve as a marker of prevalent CHD risk in a cross-sectional study of a population with low cholesterol levels (4.61 mmol/L in men and 4.82 mmol/L in women) but higher prevalence of other risk factors. In 1,046 participants of the Turkish Adult Risk Factor Survey in 2000, high-sensitivity CRP as well as other risk variables were evaluated, and CHD was diagnosed, based on clinical findings and Minnesota coding of electrocardiograms at rest. Almost an equal number of men and women > or = 30 years of age constituted the population sample of the western regions of Turkey. Geometric mean value of CRP was 1.9 mg/L (interquartile range 0.8 to 4.3), without revealing a significant difference in gender. CRP was correlated with many variables, notably those involving central obesity, fibrinogen, and apolipoprotein-B, but not with smoking status (regardless of age adjustment). In multiple regression models, blood fibrinogen, waist circumference, total cholesterol, and physical activity grade were independently associated with log CRP concentrations. Among many risk variables, CRP quartiles and systolic blood pressure were, besides age and gender, the only significant independent determinants of CHD. The age-adjusted odds ratio for CHD in the highest as opposed to the lowest quartile was 4.48 (p < 0.001). Even after adjustment for the 5 previously mentioned determinants of CRP, a 4.2-fold increased risk of CHD still persisted between the highest and lowest quartiles. Thus, the observed increased risk was not in large part due to the intermediary effects of fibrinogen, nor were some indicators of insulin resistance, but interaction appeared to be independent of these effects. Thus, CRP values serve as a marker of prevalent CHD risk in populations with low cholesterol levels. This association is independent of, or in addition to, the effects of conventional risk factors, suggesting that the contribution of chronic low-grade inflammation to the atherothrombotic process is present even in the setting of low cholesterol levels.

Metabolic syndrome: major impact on coronary risk in a population with low cholesterol levels--a prospective and cross-sectional evaluation.

UNLABELLED: The prevalence and the excess coronary heart disease (CHD) risk of the metabolic syndrome (MS) and its components were investigated in the Turkish Adult Risk Factor Study in both a prospective and a cross-sectional manner. In a population sample, representative of Turkish adults who have low levels of high- and low-density lipoprotein-cholesterol (HDL-C and LDL-C), MS was identified in conformity with the definition used in the recent NCEP guidelines. Prospective analysis was based on 2398 men and women (mean age at baseline 49.1+/-13 years) who had a baseline examination in 1997/98 and were followed-up for a mean of 3 years. CHD was diagnosed based on clinical findings and Minnesota coding of resting electrocardiograms. Fatal and nonfatal CHD developed in 126 subjects. 27% of men and 38.6% of women were found to have MS at baseline examination. When adjusted for age, MS was an independent predictor of subsequent overall fatal and nonfatal CHD in both genders, displaying an RR of 1.71. At the final cross-sectional evaluation, coronary risk associated with MS in men was primarily accounted for by standard MS components (largely inherent in glucose intolerance, hypertension and in a surrogate of small, dense LDL particles), in addition to a minor independent contribution by C-reactive protein (CRP). In women with MS, a substantial residual coronary risk remained after controlling for five components, which was partly accounted for by levels of LDL-C and CRP. It was estimated that MS was the culprit in just over half the cases of CHD in Turkey. CONCLUSION: MS was the major determinant of CHD risk in a population having generally low levels of HDL-C and LDL-C in middle-aged and elderly adults, extending to three out of every eight adults, and imposing an overall excess CHD risk of approximately 70%. In contrast to men, a substantial residual coronary risk is retained in Turkish women after controlling for five MS components.

Apolipoprotein C-III, a strong discriminant of coronary risk in men and a determinant of the metabolic syndrome in both genders.

AIMS: Apolipoprotein C-III (apoC-III) has been recognized as a useful marker of triglyceride-rich lipoproteins (TRLs) metabolism and proposed as an indicator of prognosis for coronary risk in healthy subjects. We studied cross-sectionally in a population having low cholesterol levels, but a high prevalence of the metabolic syndrome, whether serum levels of total apoC-III or its sub-fractions were independent markers of prevalent coronary heart disease (CHD) or were related to variables reflecting the metabolic syndrome. METHODS AND RESULTS: In 857 unselected participants of the representative population sample of the Turkish Adult Risk Factor Survey in 2001, apoC-III as well as other risk variables were evaluated, and CHD was diagnosed based on clinical findings and Minnesota coding of resting electrocardiograms. The sample consisted of men and women, aged 33-82 years, having a mean waist circumference of 89.4 and 92.9 cm, respectively, 42% of whom had the metabolic syndrome identified by criteria of the ATP III. ApoC-III values were measured by turbidimetric immunoassay. Mean concentrations for non-high-density lipoprotein (nonHDL) apoC-III in men and women were 6.4 and 6.2 mg/dl, respectively, and for apoC-III in HDL were 6.2 and 6.3 mg/dl, respectively. NonHDL apoC-III was similar to, and apoC-III in HDL was higher than that in Western populations. Both fractions of apoC-III were significantly correlated with lipids, lipoproteins, apoB, anthropometric measures, and blood pressures in both genders. Correlations for both were high with serum triglycerides (r(s)=around 0.70) and apoB (r(p)=around 0.37). Total apoC-III as well as both fractions were significantly correlated in women also with levels of inflammatory risk markers: strongly (r=0.40-0.45, P<0.001) with complement C3, and weakly (r(s)=around 0.20, P<0.001) with C-reactive protein. A cutoff of >7.0 mg/dl as opposed to lower levels of nonHDL apoC-III indicated the presence of hypertriglyceridemic hyperapo B with an age-adjusted odds ratio (OR) of 13.8; it indicated the presence of metabolic syndrome with 4.66-fold likelihood. Total apoC-III and nonHDL apoC-III proved to be significantly (P-trend <0.05 and 0.002) and strongly associated with prevalent CHD in men even after adjustment for age, low-density lipoprotein-cholesterol (LDL-C) and high-density lipoprotein-cholesterol (HDL-C): OR gradients across upper and lower quartiles were 3.88-fold (CI: 1.3; 11.4) and 8.8-fold (CI: 2.6; 29.8), respectively. CONCLUSIONS: In a population among whom the metabolic syndrome prevails, total- and nonHDL apoC-III are each a determinant in both genders of the metabolic syndrome and of hypertriglyceridemic hyperapo B. Each is a powerful significant marker of prevalent CHD in men independent of LDL- and HDL-C levels. In women, despite being correlated with inflammatory risk markers, the significant association of elevated levels of apoC-III with CHD did not prove to be independent of age.

Fasting insulin levels independently associated with coronary heart disease in non-diabetic Turkish men and women.

BACKGROUND: Levels of plasma insulin have been recognized as a weak risk indicator for coronary or cardiovascular risk in the general population with ethnic background and gender modifying this relationship. We assessed whether insulin concentrations are associated with or would serve as a marker of prevalent coronary heart disease risk in a cross-sectional study of a population having low cholesterol levels (just under 5 mmol/l) but higher prevalence of components of the metabolic syndrome. METHODS: In 688 participants of the Turkish Adult Risk Factor Survey in 2001, plasma insulin values as well as other risk variables were evaluated, and coronary heart disease was diagnosed based on clinical findings and Minnesota coding of resting electrocardiograms. Nearly equal numbers of men and women (>30 years of age) constituted the population sample from the two largest regions of Turkey. Concentrations of insulin were determined by the chemiluminescent immunometric method. RESULTS: Geometric mean value was 50 pmol/l (interquartile range 37-68 pmol/l), without revealing a significant difference in genders. Fasting insulin was correlated in both genders with many variables, notably those involving central obesity, triglycerides, blood pressure, physical inactivity and, inversely, with high-density lipoprotein (HDL)-cholesterol. In a regression model, waist circumference and body mass index were strongly associated with log insulin, after controlling for age and presence of coronary heart disease. The age- and obesity-adjusted odds ratio for coronary heart disease in the highest as opposed to the lowest quartile was 2-fold in both genders (P<0.05). Even after adjustment for dyslipidemia, blood pressure, glucose intolerance, physical activity and smoking status, an over 2-fold increased coronary heart disease risk still persisted with regard to hyperinsulinemia (>or=10 mU/l, 69.5 pmol/l). When C-reactive protein which was correlated with fasting insulin only in women, was added to the model, the impact of hyperinsulinemia on coronary heart disease risk remained unchanged. CONCLUSION: Hyperinsulinemia (i) may provide information on the coronary heart disease likelihood over and above that provided by the other risk factors, including HDL-cholesterol, and (ii) may contribute, within the frame of insulin resistance, to the coronary heart disease risk independently of the classical risk factors.

Endoluminal repair of peripheral arterial aneurysms: 4-year experience with the cragg endopro system I.

PURPOSE: To assess the efficiency and long-term patency of the Cragg EndoPro System I in patients with peripheral arterial aneurysms. MATERIALS AND METHODS: In 10 patients, 13 stent-grafts were used to treat 15 arterial aneurysms. Aneurysms were located in the common iliac (n = 4), superficial femoral (n = 4), popliteal (n = 3), and subclavian arteries (n = 2), and in a femoropopliteal bypass-graft (n = 2). Follow-up ranged between 2 and 46 months (mean, 36 months). Examination included clinical status, color-coded duplex sonography, computed tomography angiography, and intra-arterial digital subtraction angiography (DSA). RESULTS: Technical success was achieved in all patients. Primary patency was four of four in iliac vessels and three of nine in non-iliac vessels; secondary patency in noniliac vessels was four of nine. Repairs included one local lysis, four percutaneous transluminal angioplasties, one surgical thrombectomy, and one bypass surgery. Stent wire disintegration was detected in one of four iliac stent-grafts and in seven of nine noniliac stent-grafts. In noniliac grafts, significant stenoses occurred in three of nine; occlusion occurred in five of nine. One complication at the iliac level was a vessel wall penetration at the proximal stent edge, with development of a new aneurysmal formation. No late endoleaks were found. CONCLUSION: Exclusion of peripheral arterial aneurysms with stent-grafts is feasible. Long-term results are excellent in iliac vessels. Mechanical weakness of the stent assembly and frequent re-stenoses or occlusions are significant drawbacks in noniliac vessels with low patency rates.

The microenvironment effect on the generation of reactive oxygen species by Pd-bacteriopheophorbide.

Generation of reactive oxygen species (ROS) is the hallmark of important biological processes and photodynamic therapy (PDT), where ROS production results from in situ illumination of certain dyes. Here we test the hypothesis that the yield, fate, and efficacy of the species evolved highly depend on the dye's environment. We show that Pd-bacteriopheophorbide (Pd-Bpheid), a useful reagent for vascular targeted PDT (VTP) of solid tumors, which has recently entered into phase II clinical trials under the code name WST09 (trade name TOOKAD), forms appreciable amounts of hydroxyl radicals, superoxide radicals, and probably hydrogen peroxide in aqueous medium but not in organic solvents where singlet oxygen almost exclusively forms. Evidence is provided by pico- and nanosecond time-resolved spectroscopies, ESR spectroscopy with spin-traps, time-resolved singlet oxygen phosphorescence, and chemical product analysis. The quantum yield for singlet oxygen formation falls from approximately 1 in organic solvents to approximately 0.5 in membrane-like systems (micelles or liposomes), where superoxide and hydroxyl radicals form at a minimal quantum yield of 0.1%. Analysis of photochemical products suggests that the formation of oxygen radicals involves both electron and proton transfer from (3)Pd-Bpheid at the membrane/water interface to a colliding oxygen molecule, consequently forming superoxide, then hydrogen peroxide, and finally hydroxyl radicals, with no need for metal catalysis. The ability of bacteriochlorophyll (Bchl) derivatives to form such radicals upon excitation at the near infrared (NIR) domain opens new avenues in PDT and research of redox regulation in animals and plants.

Analyzing the process and content of genetic counseling in familial breast cancer consultations.

A detailed examination of the process of genetic counseling has been identified as a priority area for research by previous authors. This multicenter longitudinal study examined the process and content of genetic counseling in initial consultations with women from high-risk breast cancer families. One hundred and fifty-eight consultations with women unaffected and affected with breast cancer were audio taped and transcribed verbatim. A detailed coding system was developed. Clinical geneticists and genetic counselors demonstrated consistently good practice in giving detailed information on essential aspects related to familial breast cancer such as screening and management, genetic testing, breast cancer genetics, and prophylactic surgery. Eliciting emotional concerns and facilitating communication were found to be inconsistently present. As clinical practice guidelines and the general communication literature emphasize the importance of these factors, this is an area where training in or self-monitoring of such behaviors may assist consultants to further develop these skills.

Measures of abdominal obesity assessed for visceral adiposity and relation to coronary risk.

AIMS: We aimed to identify by computed tomography (CT) the best suited of three anthropometric indices that reflect the visceral adipose tissue (VAT), and to discern the relationship between VAT and certain atherogenic risk factors and coronary heart disease (CHD) diagnosis in a population sample which had a high (34%) prevalence of the metabolic syndrome (MS). METHODS: A single-scan CT was performed between the fourth and fifth lumbar vertebrae in 157 unselected men and women aged 34-69 y. Total adipose tissue area, abdominal VAT area and the abdominal sagittal diameter were determined. Diagnosis of CHD was based on clinical findings and Minnesota coding of resting electrocardiograms. RESULTS: Men had significantly higher VAT than women. Linear regression analysis for correlates of abdominal VAT area, in a model comprising age, sex, waist circumference, waist-to-hip ratio (WHR) and body mass index (BMI) identified waist circumference as the only independent variable (P<0.001). Waist circumference in men and BMI in women were the independently associated parameters of sagittal diameter (P<0.001). By stepwise linear regression, it was elicited that VAT area rose significantly by a mean of 6.8 cm2 in men and 3 cm2 in women for every 1 cm increment in waist circumference, independent of WHR. Age in women and (inversely) BMI in men were further independent variables, indicating in men that a lower BMI at a given waist girth suggests the existence of a higher VAT. Apo B and HDL-cholesterol (HDL-C) in men, and the latter in women were independently associated with VAT area in linear regression models that also comprised triglycerides, fasting insulin and C-reactive protein concentrations. In the study sample comprising 13 individuals with a CHD diagnosis, the age-adjusted odds ratio of cutpoints of VAT area > vs <140 cm2 in men and > vs <120 cm2 in women was 11.3 (95% CI (1.37, 93)). CONCLUSIONS: The best surrogate of visceral adiposity across a wide age range is waist circumference, in a population in which MS prevails. Apo B and HDL-C in men, and the latter in women were independently associated with VAT area, which proved to be closely related to CHD risk. A lower BMI at a given waist girth in men suggests the existence of a higher VAT.
