Abstract
INTRODUCTION Cardio-ankle vascular index (CAVI) is an arterial stiffness index that correlates inversely with body mass index (BMI) and subcutaneous fat area. Lipoprotein lipase (LPL) that catalyzes the hydrolysis of serum triglycerides is produced mainly in adipocytes. Serum LPL mass reflects LPL expression in adipose tissue, and its changes correlate inversely with changes in CAVI. We hypothesized that LPL derived from subcutaneous adipose tissue (SAT) suppresses the progression of arteriosclerosis and examined the relationship of LPL gene expression in different adipose tissues and serum LPL mass with CAVI in Japanese patients with severe obesity undergoing laparoscopic sleeve gastrectomy (LSG). METHODS This study was a single-center retrospective database analysis. Fifty Japanese patients who underwent LSG and had 1-year postoperative follow-up data were enrolled (mean age 47.5 years, baseline BMI 46.6 kg/m2, baseline HbA1c 6.7%). SAT and visceral adipose tissue (VAT) samples were obtained during LSG surgery. LPL gene expression was analyzed by real-time PCR. Serum LPL mass was measured by ELISA using a specific monoclonal antibody against LPL. RESULTS At baseline, LPL mRNA expression in SAT correlated positively with serum LPL mass, but LPL mRNA expression in VAT did not. LPL mRNA expression in SAT was correlated, and serum LPL mass tended to correlate inversely with the number of metabolic syndrome symptoms, but LPL mRNA expression in VAT did not. LPL mRNA expression in SAT and CAVI tended to correlate inversely in the group with visceral-to-subcutaneous fat ratio of 0.4 or higher, which is considered metabolically severe. Serum LPL mass increased 1 year after LSG. Change in serum LPL mass at 1 year after LSG tended to be an independent factor inversely associated with change in CAVI. CONCLUSIONS Serum LPL mass reflected LPL mRNA expression in SAT in Japanese patients with severe obesity, and LPL mRNA expression in SAT was associated with CAVI in patients with visceral obesity. The change in serum LPL mass after LSG tended to independently contribute inversely to the change in CAVI. This study suggests that LPL derived from SAT may suppress the progression of arteriosclerosis.

Thickness and Volume of Epicardial Adipose Tissue in Relation to Stiffness and Elasticity of Aorta Assessed by Computed Tomography Angiography. Biomedicines 2023; 11:1617. [PMID: 37371711 DOI: 10.3390/biomedicines11061617] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 05/26/2023] [Accepted: 05/30/2023] [Indexed: 06/29/2023] Open
Abstract
PURPOSE The aim of the study was to assess the importance of the measurements of thickness and volume of epicardial adipose tissue (EAT) in coronary computed tomography angiography (CCTA) as a predictive factor of increased stiffness and impaired elasticity of aorta. METHODS AND MATERIALS The study involved a group of 97 patients (63.48 ± 8.50 years). In accordance with the medians of epicardial adipose tissue (EAT) parameters, aortic elasticity and stiffness parameters, patients were divided into subgroups: EAT thickness median 9.40 mm, EAT volume median 61.95 mL, EAT thickness index 5.08 mm/m2 and EAT volume index 34.33 mL/m2. RESULTS The mean coronary artery calcium score was 162.24 (±317.69). The mean aortic stiffness index was 4.18 (±0.81). The assessed mean aortic elasticity parameters were 3.29% (±2.37) and 0.12 cm2/dyn (±0.09) for strain and distensibility, respectively. A positive linear correlation was observed between EAT parameters and aortic stiffness (0.21), volume (0.51), thickness index (0.24), volume index (0.55) and, for aorta elasticity, a negative linear correlation between the following EAT parameters was observed: thickness (-0.32 and -0.30), volume (-0.49 and -0.48), thickness index (-0.34 and -0.31), volume index (-0.51 and -0.49) and aortic elasticity parameters (aorta strain and aorta distensibility, respectively). CONCLUSION The study showed that CCTA illustrates a relationship between the parameters of EAT and an increased stiffness of the aorta, while the most predictive factor of stiffness was the volume index.

Abstract
AIM We investigated the effects of metabolic syndrome (MetS) and its components, including a body shape index (ABSI), on increased arterial stiffness measured using the cardio-ankle vascular index (CAVI) according to sex and age strata. METHODS A total of 7127 asymptomatic Korean participants aged 21-90 years (men, 69.4%) were included. Age-sex-specific increased CAVI was defined as having the highest quartile of CAVI in each age group. RESULTS The CAVI increased with age and was higher in men. MetS was associated with an increased risk of high CAVI by 1.30 times in men and 1.45 times in women. The risk of high CAVI with an increasing MetS risk score was greater in women. MetS was significantly associated with increased CAVI in men only aged 51-70 years and in women aged ≥ 51 years, and the size of association increased with age (odds ratio (OR) of 1.41 in 51-70 years vs. OR of 2.96 in ≥ 71 years of women). Among MetS components, triglyceride (men, all ages), hypertension (men, 51-70 years; women, ≤ 70 years), glucose intolerance (men, 51-70 years; women, ≥ 51 years), and HDL-cholesterol (women, ≥ 71 years) were associated with increased CAVI.Unlike increased waist circumference (WC), increased ABSI revealed an association with high CAVI. MetS diagnosed with ABSI instead of WC was more significantly associated with increased CAVI in all age-sex groups. CONCLUSION The association of MetS and its components with increased CAVI differed with age and sex, which might provide a new insight for the management of MetS risk factors to promote vascular health.

Vasc Health Risk Manag 2022; 18:721-733. [PMID: 36120718 PMCID: PMC9480599 DOI: 10.2147/vhrm.s378288] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2022] [Accepted: 08/24/2022] [Indexed: 11/23/2022] Open
Abstract
Obesity has been known to relate to various diseases and metabolic disorders. Since the implication of body shape has been mentioned, obesity can be divided into visceral obesity and subcutaneous obesity. The former is considered the upstream pathophysiology of metabolic syndrome (MetS), and has been emphasized worldwide for the prevention of cardiovascular diseases in the last quarter century. However, some prospective studies have shown that cardiovascular mortality and morbidity are not necessarily higher in patients with MetS compared to those without. Recently, cardio-ankle vascular index (CAVI) has been established as an indicator of arteriosclerosis. This parameter is independent of blood pressure at the measuring time, and reflects systemic arterial stiffness from the aortic origin to the ankle. However, since CAVI is not necessarily high in MetS patients, attempts have been made to clarify this unexpected phenomenon. In several studies, CAVI was found to correlate negatively with body mass index (BMI), and also with waist circumference (WC) which is a widely used representative visceral obesity index. On the other hand, a body shape index (ABSI) is also a visceral obesity index designed to be minimally associated with BMI, and is calculated by dividing WC by an allometric regression of weight and height. Replacing high WC with high ABSI in MetS diagnosis promoted the identification of MetS patients with increased CAVI in cross-sectional studies on Japanese and Korean populations. Additionally, the incidence of MetS diagnosed using high ABSI was associated with significant increase in CAVI after 1 year of observation. Enhanced predictive ability for renal function decline by replacing WC with ABSI in MetS diagnosis was also observed in a longitudinal study in Japanese urban residents. These findings suggest that MetS diagnosis using high ABSI instead of high WC as a visceral obesity index needs to be reconsidered. However, further research is desirable on Caucasian, whose body shape differs slightly from that of Asians.

Abstract
Aim A link between low muscle mass and arterial stiffness is not always consistent. In this study, we aimed to evaluate the clinical significance of low skeletal muscle mass in relation to arterial stiffness measured by the cardio-ankle vascular index (CAVI). Methods A total of 2,561 asymptomatic Korean subjects who underwent bioelectrical impedance analysis (BIA) and CAVI were included for analysis. Using appendicular skeletal muscle mass (ASM), classes I and II sarcopenia were defined as ASM% greater than 1 standard deviation (SD) and 2 SDs below the gender-specific mean of healthy young Korean adults. Results Compared to normal, CAVI was significantly higher, but the number of patients with a low ankle-brachial index (ABI) was not significantly different (p < 0.001 for CAVI, p = 0.078 for ABI). Classes I and II sarcopenia showed an independent and significant association with CAVI (estimate 0.148, standard error (SE) 0.043, p < 0.001 and estimate 0.304, SE 0.073, p < 0.001 for classes I and II sarcopenia, respectively, adjusted for age groups, gender, body mass index (BMI) ≥25, hypertension, diabetes, hypercholesterolemia, and smoking). Conclusion Low muscle mass is independently and significantly associated with increased CAVI, and should be considered when managing asymptomatic subjects to assess the risk of atherosclerosis.

Abstract
OBJECTIVE Heart failure with preserved ejection fraction (HFpEF) is an intricacy heterogeneous syndrome. However, the association between EAT and arterial stiffness in HFpEF patients remains unknown. METHODS A total of 102 patients were enrolled into the study, and brachial-ankle pulse-wave velocity (baPWV), epicardial adipose tissue (EAT) and body composition were assessed. Linear regression analysis was carried out to model the relationship between variables (especially EAT thickness) and baPWV. RESULTS The results showed that patients with the thicker EAT fat pad (≥3.55 mm) tended to have comorbidities of hypertension, coronary artery disease (CAD), diabetes and hyperlipidemia, also with a higher level of obesity, fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c), total cholesterol (TC) and triglyceride (TG). The level of baPWV was higher in EAT ≥3.55 mm group than the other group. BaPWV was positively associated with EAT, age, heart rate, waist circumference, visceral fat area, systolic and diastolic blood pressure, CRP and FBG. After adjusting for EAT, age and visceral fat area, EAT thickness (β = 0.256, P = 0.009) and visceral fat area (β = 0.229, P = 0.036) significantly associated with baPWV. CONCLUSION The study assessed for the first time that the increased EAT thickness was closely related with baPWV in HFpEF patients, suggesting patients with the thicker EAT may be independently associated with arterial stiffness under the context of HFpEF.

Abstract
Objective Arterial stiffness is related to arteriolosclerotic diseases and is a marker of adverse cardiovascular events. Mitral annular calcification (MAC) is progressive calcium deposition on the posterior and inferior mitral annulus and is associated with atherosclerotic cardiovascular diseases. Cardio-ankle vascular index (CAVI) is a measurement technique used to estimate the degree of arterial stiffness without effect from blood pressure. The aim of this study is to research arterial stiffness using CAVI in patients with MAC. Materials and Methods The study was cross-sectional and observational and included 98 patients with MAC confirmed by echocardiography who referred to the cardiology clinics and met study inclusion criteria and 38 controls without MAC. CAVI measurements were obtained by using the Vascular Screening System VaSera VS-1000 (Fukuda Denshi, Tokyo, Japan) device. Results The two groups were similar in terms of demographic characteristics, including age, sex, hypertension, coronary artery disease, body surface area, and smoking (P > .05). Left atrial volume index was significantly higher in patients with MAC compared with the control group (P < .001). Right arm CAVI, left arm CAVI, and mean CAVI were significantly higher in the MAC group than the control group (P = .037, P = .005, and P = .014, respectively) and increased with MAC severity. There was a significant positive correlation between mean CAVI and MAC grade (r = 0.278, P = .001). Also, when ankle-brachial index (ABI) was measured with CAVI, left and right extremity ABI values were significantly lower in patients with MAC (P = .017 and P = .005, respectively). Conclusion CAVI increased in all patients with MAC and associated with increasing grade of calcification.

Abstract
Atrial fibrillation (AF) is the most common arrhythmia in the elderly. Arterial stiffness may predict the risk of AF, but this relationship has not been fully evaluated. We assessed the association between arterial stiffness and prevalent AF. All subjects who had electrocardiography performed and a cardio-ankle vascular index (CAVI) calculated during a screening examination between 2010 and 2019 were enrolled. To evaluate the association between increased arterial stiffness and AF, we divided the population according to their Framingham risk score (FRS) into low-, intermediate-, and high-risk groups. A total of 8048 subjects were evaluated. The multivariate analysis revealed that increased arterial stiffness was significantly associated with AF prevalence, even after adjusting cardiovascular risk factors [odds ratio (OR) 1.685, 95% confidence interval (CI) 1.908–2.588, p = 0.017]. When we subcategorized the subjects according to their FRS, increased arterial stiffness was significantly associated with AF in the intermediate- and high-risk groups (OR 3.062, 95% CI 1.39-6.740 and OR3.877, 95% CI 1.142-13.167, respectively, BMI adjusted. High arterial stiffness shows a significant association with AF in those with intermediate or high cardiovascular risk, and can be used for further risk stratification of patients.

Abstract
Introduction A combined assessment of different parameters of cardiovascular (CV) risk and prognosis can be supportive and performed with cardiac magnetic resonance (CMR). Aortic stiffness, epicardial fat volume (EFV), left ventricular (LV) strain and fibrosis were evaluated within a single CMR examination and results were related to the presence of hypertension (HTN) and diabetes mellitus (DM). Methods 20 healthy controls (57.2 ± 8.2 years(y); 26.2 ± 3.9 kg/m2), 31 hypertensive patients without DM (59.6 ± 6.7 y; 28.4 ± 4.7 kg/m2) and 12 hypertensive patients with DM (58.8 ± 9.9y; 30.7 ± 6.3 kg/m2) were examined at 1.5Tesla. Aortic stiffness was evaluated by calculation of aortic pulse wave velocity (PWV), EFV by a 3D-Dixon sequence. Longitudinal & circumferential systolic myocardial strain (LS; CS) were analyzed and T1-relaxation times (T1) were determined to detect myocardial fibrosis. Results EFV was highest in hypertensive patients with diabetes (78.4 ± 28.0 ml/m2) followed by only hypertensive patients (64.2 ± 27.3 ml/m2) and lowest in controls (50.3 ± 22.7 ml/m2; p < 0.05). PWV was higher in hypertensive patients with diabetes (9.8 ± 3.3 m/s) compared to only hypertensive patients (8.6 ± 1.7 m/s; p < 0.05) and to controls (8.1 ± 1.9 m/s; p < 0.05). LS&CS were worse in hypertensive patients with diabetes (LS:-20.9 ± 5.1% and CS: -24.4 ± 5.7%) compared to both only hypertensive patients (LS: -24.7 ± 4.6%; CS: -27.1 ± 5.0%; p < 0.05) and to controls (LS: -25.5 ± 3.8; CS: -28.3 ± 4.1%; p < 0.05). Both hypertensive groups with and without DM had higher T1́s (994.0 ± 43.2 ms; 991.6 ± 35.5 ms) than controls (964.6 ± 40.3 ms; p < 0.05). Conclusion CMR revealed increased aortic stiffness and EFV in hypertensive patients, which were even higher in the presence of DM. Also signs of LV myocardial fibrosis and a reduced strain were revealed. These parameters support the assessment of CV risk and prognosis. They can accurately be measured with CMR within a single examination when normally different techniques are needed.

The predictive value of the epicardial adipose thickness in the rate of expansion of the aortic root. Herz 2019; 46:48-53. [PMID: 31728554 DOI: 10.1007/s00059-019-04865-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Revised: 09/14/2019] [Accepted: 10/10/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND Epicardial adipose tissue (ECAT) is metabolically active and is involved in the development of atherosclerosis. The thickness of ECAT has been positively correlated with the dimensions of the ascending aorta. We aimed to examine whether ECAT thickness predicted the expansion of the aortic dimensions. METHODS The imaging results of patients who had undergone transthoracic echocardiographic (TTE) examinations more than twice during the period 2005-2015 were surveyed. We included adult patients who had undergone TTE examinations at least 1 year apart. The ECAT was measured in the parasternal long-axis view from the index TTE study. End-diastolic dimensions in three consecutive beats were averaged for all measurements. The annulus, root, and sinotubular junction (STJ) were also measured. The amount of increase (if any) in aortic dimensions per year was calculated and the correlation of this increase with the initial thickness of the ECAT was analyzed. RESULTS In total, 429 examinations were performed with 197 patients (17 females), from which 394 examinations were analyzed. The ECAT thickness was 8.6 ± 3.6 mm. In the initial examinations, the annulus, STJ, and root measured 23 ± 4, 28 ± 4, and 34 ± 4 mm, respectively. In univariate analysis, for every 1 mm of ECAT thickness, the STJ expanded 0.056 (95% CI: 0.001-0.112 mm/year; p = 0.030) and the aortic root expanded 0.088 mm/year (p < 0.001). In multivariate analysis, ECAT thickness remained an independent predictor of the aortic root expansion. For every 1‑mm increase in ECAT thickness, the aortic root expanded by 0.036 mm (95% CI: 0.010-0.062) per year (p = 0.007). CONCLUSION The thickness of the ECAT is a predictor of more rapid increases in the dimensions of the aortic root. Further studies of patients with established aortic aneurysm are warranted.

Abstract
Both small and large artery disease might precede the development of hypertension. However, no prospective trial has yet determined the role of small and large artery disease on the rate of new-onset hypertension in a normotensive general population. This study investigated associations between both arterial stiffness and small artery retinopathy and the development of hypertension in adults from Japan. Normotensive individuals who underwent a baseline health checkup from 2005 to 2015 and at least 1 annual follow-up were eligible. The cardio-ankle vascular index (CAVI) was measured, and retinal fundus photography was performed at baseline. Follow-up visits included measurement of clinic blood pressure. The primary end point was new-onset hypertension (blood pressure ≥140/90 mm Hg or initiation of antihypertensive medication with self-reported hypertension). The analysis included 34 649 subjects (mean age, 44.2 years; 46.4% male). Mean follow-up duration was 3.18±2.50 years. The cumulative incidence of new-onset hypertension during the 10-year follow-up period was 40% of patients overall, with rates increasing in parallel with baseline CAVI (quartile [Q]1, 23%; Q2, 33%; Q3, 42%; Q4, 58%; P<0.001), and as the severity of retinopathy increased ( P<0.001). CAVI showed good discriminative ability for detecting new-onset hypertension. In multivariate analysis, both CAVI and small artery retinopathy were independent predictors of hypertension development. There was no interaction between CAVI and small artery retinopathy with respect to incident hypertension. In conclusion, we showed that both large and small artery disease predict future hypertension independently of each other and confounding risk factors in a general normotensive population.

Abstract
Background Chronic systemic inflammation is an important causative factor in the pathogenesis of atherosclerosis. However, the effect of chronic Helicobacter pylori (Hp) infection on arterial stiffness, a predictor of cardiovascular events, remains unclear. We evaluated the association between Hp infection and arterial stiffness in asymptomatic healthy individuals. Methods Arterial stiffness was evaluated using the cardio-ankle vascular index (CAVI). We included subjects who underwent CAVI and anti-Hp IgG antibody evaluations, simultaneously, between March 2013 and July 2017. Demographic characteristics and metabolic and cardiovascular parameters were compared with respect to anti-Hp IgG antibody status. Multivariable logistic regression analyses were performed to determine the effect of Hp-seropositivity and conventional cardiovascular risk factors on arterial stiffness. Results Of 2,251 subjects, 1,326 (58.9%) were included in the Hp-seropositive group. Median age (P < 0.001) and systolic blood pressure (P = 0.027) were significantly higher in the Hp-seropositive than in the Hp-seronegative group. Levels of LDL-cholesterol were significantly higher in the Hp-seropositive than in the Hp-seronegative group (P = 0.016). Other serum metabolic parameters were not significantly different between the two groups. The median CAVI value and the proportion of subjects with a CAVI ≥ 8 were significantly higher in the Hp-seropositive than in the Hp-seronegative group (both P < 0.001). On multivariable logistic regression analyses, Hp-seropositivity, age, body mass index, waist circumference, smoking, hypertension, diabetes mellitus, and dyslipidemia were significantly associated with high CAVI values. In the subgroup analysis conducted according to age group, a tendency towards an increased association between Hp-seropositivity and CAVI was observed with increasing age, even though the difference did not reach the statistical significance. Conclusions Hp-seropositivity was significantly associated with arterial stiffness. Hp infection may contribute to the development of cardiovascular diseases.

Abstract
Aim: Obesity is a social problem due to the prevalence of the Western lifestyle. In particular, visceral fat accumulation, which is a main component of metabolic syndrome, is closely associated with the progression of atherosclerosis. This study aimed to investigate the relationships of obesity-related indices and metabolic syndrome with subclinical atherosclerosis in middle-aged untreated workers. Methods: Employees undergoing their periodic health check-up but without previous cardiovascular events or cardiovascular medications were enrolled in this study (n = 7,750). Body mass index (BMI), percent body fat, waist circumference, and visceral fat area were evaluated as obesity-related indices. Assessment of visceral fat area was performed by computed tomography (CT). Subclinical atherosclerosis was assessed by measuring arterial stiffness using cardio-ankle vascular index (CAVI) and by ultrasound examination of carotid intima-media thickness (IMT). Results: Obesity-related indices were significantly correlated with each other and were positively associated with carotid IMT but negatively associated with CAVI in multivariate regression analysis. In a logistic regression analysis including CAVI and carotid IMT simultaneously, CAVI was negatively associated, but carotid IMT was positively associated, with obesity defined by each obesity-related index. In contrast, both CAVI and carotid IMT were positively associated with the presence of metabolic syndrome based on visceral fat accumulation. Conclusions: Obesity-related indices were negatively associated with CAVI and positively associated with carotid IMT in middle-aged untreated workers, while both CAVI and carotid IMT were worsened in the presence of metabolic syndrome.

Effects of metabolic syndrome on arterial function in different age groups: the Advanced Approach to Arterial Stiffness study. J Hypertens 2019; 36:824-833.

Abstract
OBJECTIVE The aim of the Advanced Approach to Arterial Stiffness study was to compare arterial stiffness measured simultaneously with two different methods in different age groups of middle-aged and older adults with or without metabolic syndrome (MetS). The specific effects of the different MetS components on arterial stiffness were also studied. METHODS This prospective, multicentre, international study included 2224 patients aged 40 years and older, 1664 with and 560 without MetS. Patients were enrolled in 32 centres from 18 European countries affiliated to the International Society of Vascular Health & Aging. Arterial stiffness was evaluated using the cardio-ankle vascular index (CAVI) and the carotid-femoral pulse wave velocity (CF-PWV) in four prespecified age groups: 40-49, 50-59, 60-74, 75-90 years. In this report, we present the baseline data of this study. RESULTS Both CF-PWV and CAVI increased with age, with a higher correlation coefficient for CAVI (comparison of coefficients P < 0.001). Age-adjusted and sex-adjusted values of CF-PWV and CAVI were weakly intercorrelated (r = 0.06, P < 0.001). Age-adjusted and sex-adjusted values for CF-PWV but not CAVI were higher in presence of MetS (CF-PWV: 9.57 ± 0.06 vs. 8.65 ± 0.10, P < 0.001; CAVI: 8.34 ± 0.03 vs. 8.29 ± 0.04, P = 0.40; mean ± SEM; MetS vs. no MetS). The absence of an overall effect of MetS on CAVI was related to the heterogeneous effects of the components of MetS on this parameter: CAVI was positively associated with the high glycaemia and high blood pressure components, whereas lacked significant associations with the HDL and triglycerides components while exhibiting a negative association with the overweight component. In contrast, all five MetS components showed positive associations with CF-PWV. CONCLUSION This large European multicentre study reveals a differential impact of MetS and age on CAVI and CF-PWV and suggests that age may have a more pronounced effect on CAVI, whereas MetS increases CF-PWV but not CAVI. This important finding may be due to heterogeneous effects of MetS components on CAVI. The clinical significance of these original results will be assessed during the longitudinal phase of the study.

Abstract
Arterial stiffness is a marker of vascular damage. Although adiposity increases cardiovascular risk, the relationship between paediatric overweight and arterial stiffness is unclear. The study aimed to evaluate the simultaneous effect of hypertension and overweight on arterial stiffness using cardio-ankle vascular index (CAVI) and related novel, theoretically blood pressure (BP)-independent, index CAVI0. CAVI and CAVI0 were measured in 140 adolescent boys (16.0 ± 1.9 years) divided into age-matched groups: normal-weight normotensives, overweight normotensives, overweight white-coat hypertensives, and overweight essential hypertensives. Overweight normotensives had significantly lower CAVI and CAVI0 compared to normal-weight normotensives (4.81 ± 0.64 vs. 5.33 ± 0.66, p < .01; 7.10 ± 0.99 vs. 7.81 ± 1.00, p < .01, respectively). CAVI and CAVI0 in overweight essential hypertensives showed no significant difference compared to normal-weight normotensives and were significantly higher compared to overweight normotensives (5.32 ± 0.77 vs. 4.81 ± 0.64, p < .01; 7.77 ± 1.19 vs. 7.10 ± 0.99, p < .01, respectively). CAVI, but not CAVI0, was associated positively with diastolic pressure (0.022 mmHg-1, p = .002) and negatively with pulse pressure (-0.022 mmHg-1, p = .001), and it was significantly higher in overweight white-coat hypertensives compared to overweight normotensives (5.20 ± 0.63 vs. 4.81 ± 0.64, p < .05). The lowering effect of overweight on arterial stiffness indexed by CAVI and CAVI0 in hypertensive adolescents seems to counterbalance the early arteriosclerotic effect of essential hypertension. The increase in CAVI, but not CAVI0, in overweight white-coat hypertensives could be attributable to residual BP dependence of CAVI, which is not present in CAVI0. Under certain conditions, CAVI0 may offer a clinically relevant improved assessment of arterial stiffness superior to CAVI.

Atherosclerosis 2017; 263:263-271. [PMID: 28704699 DOI: 10.1016/j.atherosclerosis.2017.06.031] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2017] [Revised: 06/11/2017] [Accepted: 06/15/2017] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS The association between anthropometric indices of body composition and arterial stiffness is inconclusive. The objective of this study was to examine the predictive ability of two new obesity indices: a body shape index (ABSI), and a body roundness index (BRI), for the identification of arterial stiffness among Chinese adults, as well as to compare the relative strength of association between the anthropometric indices and arterial stiffness. METHODS A total of 10,197 subjects were recruited in this cross-sectional study. We tested the association between anthropometric indices (body mass index [BMI], waist circumference [WC], waist-height-ratio [WHtR], ABSI and BRI) and brachial-ankle pulse wave velocity (PWV). Receiver operating characteristic curve and area under curve (AUC) were employed to evaluate the predictive value of the anthropometric indices for identification of arterial stiffness. RESULTS After adjusting for confounding variables, BRI (linear regression: 0.112; AUC: 0.726; OR: 1.228 for female and linear regression: 0.047; AUC: 0.631; OR: 1.173 for male) exhibited a more powerful predictive ability of arterial stiffness than ABSI (linear regression: 0.110; AUC: 0.674; OR: 1.315 for female and linear regression: 0.058; AUC: 0.610; OR: 1.150 for male) and WC (linear regression: 0.078; AUC: 0.699; logistic regression: negative for female and linear regression: negative; AUC: 0.593; logistic regression: negative for male) while having a similar predictive value to that of WHtR (linear regression: 0.113; AUC: 0.726; OR: 1.228 for female and linear regression: 0.047; AUC: 0.631; OR: 1.185 for male) among both sexes. BMI (linear and logistic regression: negative; AUC: 0.660 for female and 0.568 for male) had the lowest predictive power in both sex categories. The optimal cut-off of WHtR for detecting arterial stiffness was 0.49 in females and 0.53 in males, that of BRI was 3.19 in females and 3.89 in males. CONCLUSIONS WHtR, ABSI and BRI were significantly associated with arterial stiffness. BRI and WHtR, rather than ABSI, showed superior predictive abilities for arterial stiffness in both sexes.

Abstract
Different visceral fat compartments have several systemic effects and may play a role in the development of both insulin resistance and cardiovascular diseases. In the last couple of years special attention has been paid to the epicardial adipose tissue (EAT), which can be quantified by non-invasive cardiac imaging techniques. The epicardial fat is a unique fat compartment between the myocardium and the visceral pericardium sharing a common embryologic origin with the visceral fat depot. Epicardial adipose tissue has several specific roles, and its local effects on cardiac function are incorporated in the complex pathomechanism of coronary artery disease. Importantly, EAT may produce several adipocytokines and chemokines that may influence - through paracrine and vasocrine effects - the development and progression of coronary atherosclerosis. Epicardial adipose tissue volume has a relatively strong genetic dependence, similarly to other visceral fat depots. In this article, the anatomical and physiological as well as pathophysiological characteristics of the epicardial fat compartment are reviewed.

Abstract
BACKGROUND Arterial stiffness has been established as a surrogate marker for the prognosis of cardiovascular disease. Arterial stiffness is also a predictor of future cardiovascular events, and is the earliest detectable manifestation of adverse structural and functional changes to blood vessel walls. SUMMARY AND KEY MESSAGES The cardio-ankle vascular index (CAVI) is an index representing the stiffness of the entire arterial segments from the aorta to the ankle independent of the blood pressure at the time of the measurement. This paper provides an overview of the clinical application of arterial stiffness measurement by CAVI in asymptomatic Koreans. It includes the association between cardiometabolic risk factors and CAVI, and the relation between CAVI and asymptomatic coronary artery disease.

Abstract
INTRODUCTION The chemical components of olive fruit provide a wide range of cardiovascular benefits. Arterial stiffness is an important cardiovascular risk factor and can be assessed using the Cardio-Ankle Vascular Index (CAVI). OBJECTIVE The objective of this study was to assess the impact of a proprietary standardized olive fruit extract (SOFE) in subjects at risk for arterial stiffness. METHODS Twelve of 36 subjects were assigned to each of the following groups for this 11-day, double-blind, placebo-controlled study: Group 1: 250 mg SOFE-50 mg active ingredient, hydroxytyrosol (dosage achieved with two capsules per day); Group 2: 500 mg SOFE-100 mg active ingredient, hydroxytyrosol (dosage achieved with two capsules per day); and Group 3: placebo. RESULTS All three groups showed a decrease in CAVI scores, although no significant between-group differences were observed. Group 2 had the largest reduction, with mean CAVI scores decreasing from 11.02 to 8.91. Group 2 showed the strongest response in visual analog scale (VAS) energy intensity (11.71% increase). Results for C-reactive protein (CRP) blood levels showed no changes of statistical significance between groups. Mean triglyceride levels from Group 2 decreased by 21.64%, the most significant change among all three groups. CONCLUSIONS SOFE, an olive fruit extract containing many of the phytochemicals shown to provide cardiovascular benefits, was safe and well-tolerated. SOFE 500 mg had a greater effect on CAVI scores, suggesting improved arterial elasticity, and a clear reduction in triglycerides compared with placebo and SOFE 250 mg. The decreased CAVI scores suggest that increasing high-density lipoprotein cholesterol and lowering triglycerides with SOFE could potentially reduce patients' risk of developing atherosclerosis. Although more studies are needed, positive cardiovascular health trends, including improved vessel elasticity and positive triglyceride effects, were evident with SOFE.

Abstract
Aim: Epicardial adipose tissue (EAT) has been suggested as a contributing factor for coronary atherosclerosis based on the previous cross-sectional studies and pathophysiologic background. However, a causal relationship between EAT and the development of non-calcified coronary plaque (NCP) has not been investigated. Methods: A total of 122 asymptomatic individuals (age, 56.0 ± 7.6 years; male, 80.3%) without prior history of coronary artery disease (CAD) or metabolic syndrome and without NCP or obstructive CAD at baseline cardiac computed tomography (CT) were enrolled. Repeat cardiac CT was performed with an interval of more than 5 years. Epicardial fat volume index (EFVi; cm3/m2) was assessed in relation to the development of NCP on the follow-up CT where the results were classified into “calcified plaque (CP),” “no plaque,” and “NCP” groups. Results: On the follow-up CT performed with a median interval of 65.4 months, we observed newly developed NCP in 24 (19.7%) participants. Baseline EFVi was significantly higher in the NCP group (79.9 ± 30.3 cm3/m2) than in the CP group (63.7 ± 22.7 cm3/m2; P = 0.019) and in the no plaque group (62.5 ± 24.7 cm3/m2; P = 0.021). Multivariable logistic regression analysis demonstrated that the presence of diabetes (OR, 9.081; 95% CI, 1.682–49.034; P = 0.010) and the 3rd tertile of EFVi (OR, 4.297; 95% CI, 1.040–17.757; P = 0.044 compared to the 1st tertile) were the significant predictors for the development of NCP on follow-up CT. Conclusions: Greater amount of EAT at baseline CT independently predicts the development of NCP in asymptomatic individuals.

Abstract
OBJECTIVE To investigate the association between hypertriglyceridemic waist (HTGW) phenotype and arterial stiffness in a Chinese population without hypertension, diabetes and cardiovascular diseases. METHODS A total number of 3028 subjects aged 40 years and over were enrolled in this cross-sectional study. All participants provided a clinical history and underwent a physical examination. Brachial-ankle pulse wave velocity (baPWV) was used to evaluate arterial stiffness. HTGW phenotype was defined as the simultaneous presence of waist circumference ≥90/80 cm and triglycerides ≥2.0/1.5 mmol/L in men/women. RESULTS The prevalence of HTGW phenotype was 7.5% among healthy participants in China (Beijing), 7.4% in men and 7.5% in women. Women with HTGW phenotype had a higher level of baPWV compared with normal WC and normal triglyceride (NWNT) group (P < 0.05), but no significant difference was observed in men (P > 0.05). Multiple logistic regression analysis showed HTGW phenotype was significantly associated with baPWV after controlling for multiple factors in women. However, no significant relationship was observed in men. CONCLUSIONS The present study supports that HTGW phenotype is associated with increased arterial stiffness in women but not in men.

Abstract
Arteriosclerosis is a major contributor to cardiovascular diseases. One of the difficulties in controlling those diseases is the lack of a suitable indicator of arteriosclerosis or arterial injury in routine clinical practice. Arterial stiffness was supposed to be one of the monitoring indexes of arteriosclerosis. Cardio-ankle vascular index (CAVI) is reflecting the stiffness of the arterial tree from the origin of the aorta to the ankle, and one of the features of CAVI is independency from blood pressure at a measuring time. When doxazosin, an α1-adrenergic blocker, was administered, CAVI decreased, indicating that arterial stiffness is composed of both organic stiffness and functional stiffness, which reflects the contraction of arterial smooth muscle. CAVI shows a high value with aging and in many arteriosclerotic diseases, and is also high in persons possessing main coronary risk factors such as diabetes mellitus, metabolic syndrome, hypertension and smoking. Furthermore, when the most of those risk factors were controlled by proper methods, CAVI improved. Furthermore, the co-relationship between CAVI and heart function was demonstrated during treatment of heart failure. This paper reviews the principle and rationale of CAVI, and discusses the meaning of monitoring CAVI in following up so-called lifestyle-related diseases and cardiac dysfunction in routine clinical practice.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is associated with risk factors for cardiovascular disease. The cardioankle vascular index (CAVI), a new measure of arterial stiffness, was recently developed and is independent of blood pressure. We investigated whether NAFLD is associated with arterial stiffness as measured using the CAVI in an apparently healthy population.A total of 2954 subjects without any known liver diseases were enrolled. NAFLD was diagnosed via typical ultrasonography. The clinical characteristics examined included age, sex, body mass index (BMI), waist circumference (WC), and the levels of aspartate aminotransferase, alanine aminotransferase, total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol triglycerides, and glucose. Arterial stiffness was defined using an age- and sex-specific threshold of the upper quartile of the CAVI.NAFLD was found in 1249 (42.3%) of the analyzed subjects. Using an age-, sex-, and BMI-adjusted model, NAFLD was associated with a 42% increase in the risk for arterial stiffness (highest quartile of the CAVI). The risk for arterial stiffness increased according to the severity of NAFLD (adjusted odds ratio [95% confidence interval], 1.27 [1.02 - 1.57] vs 1.78 [1.37 - 2.31], mild vs moderate-to-severe, respectively). When adjusted for other risk factors, including BMI, WC, smoking status, diabetes, and hypertension, these relationships remained statistically significant.Patients with NAFLD are at a high risk for arterial stiffness regardless of classical risk factors. The presence of cardiometabolic risk factors may attenuate the prediction of arterial stiffness by means of NAFLD presence. Thus, physicians should carefully assess subjects with NAFLD for atherosclerosis and associated comorbidities.

Abstract
AIM To investigate the relationships between arterial stiffness and classic cardiovascular risk factors with respect to gender differences in addition to the prevalence of high arterial stiffness in Chongqing, China based on an examination of 18,336 subjects. METHODS The cardio-ankle vascular index was used as a marker of arterial stiffness. The relationships between arterial stiffness and body mass index (BMI) as well as metabolic syndrome (MetS) were estimated using logistic regression models. RESULTS The prevalence of high arterial stiffness was 12.74% in men and 9.91% in women. For age and BMI, compared with the reference group, men had higher adjusted odds ratios (ORs) in each group versus their female counterparts. For each individual index of MetS, the effects of waist circumference and systolic blood pressure (SBP) on high arterial stiffness exhibited remarkable gender differences, with women having higher ORs and adjusted ORs than men. As the sum of MetS traits increased, the ORs and adjusted ORs in the subjects also increased, with women having higher values than men in each group. CONCLUSIONS Gender-specific differences exist in the prevalence of high arterial stiffness among subjects compared by age, BMI and MetS, with varying effects of influence for these factors between genders.

Abstract
OBJECTIVE Although a relationship between post-challenge hyperglycemia and arterial stiffness has been reported, the relationship between the postprandial glucose levels and cardio-ankle vascular index (CAVI) in non-diabetic subjects is not clear. This study thus evaluated the association between the postprandial glucose levels after a composite meal and the degree of arterial stiffness measured according to CAVI in non-diabetic subjects. METHODS The subjects included 1,291 individuals (655 men and 636 women; mean age, 48.6 years; range, 23-85 years) who underwent medical examinations, including blood tests and CAVI assessments, between October 2005 and April 2012. The 1-hour postprandial glucose levels were determined after a 600-kcal traditional Japanese meal. RESULTS The CAVI values were significantly higher in the subjects with higher 1-hour postprandial glucose levels (≥140 mg/dL in men; ≥158 mg/dL in women). A simple regression analysis indicated that the CAVI values were significantly correlated with the 1-hour postprandial glucose levels in men (r=0.286, p<0.0001) and women (r=0.228, p<0.0001). After adjusting for age, BMI, systolic blood pressure, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, 1-hour postprandial glucose, homeostatis model assessment of insulin resistance, estimated glemerular filtration rate, and high sensitive C-reactive protein, stepwise multiple regression analysis demonstrated that the 1-hour postprandial glucose level was an independent predictor associated with the CAVI in men (p=0.003) and older women 50 years of age or older (p=0.003). CONCLUSION This study demonstrated that the 1-hour postprandial glucose levels are associated with increased CAVI values in non-diabetic men and older women 50 years of age or older.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is defined as glucose intolerance that has begun during pregnancy. Recent studies have proven that development of atherosclerosis may be established in this population even without presence of type 2 diabetes. For assessment of atherosclerosis, epicardial fat thickness (EFT) is recently being used as a surrogate marker. In this study, we aimed to prove that women with GDM history are more inclined to have higher EFT levels than women without GDM history. METHODS Sixty-two patients with previous GDM and 33 age- and sex-matched controls were allocated. Epicardial fat thicknesses of the subjects were measured with transthorasic echocardiography and carotid intima media thickness (c-IMT) was measured with ultrasound. Insulin resistance (IR) of each subject was assessed with Homeostasis model of assessment-insulin resistance (HOMA-IR). RESULTS Carotid IMT and EFT were significantly higher in previous GDM group than controls. Serum gamma-glutamyl transferase (GGT), uric acid, and high-sensitivity C-reactive protein (hs-CRP) levels were also found significantly higher in the patients with previous GDM as compared to the controls. We observed that carotid IMT (β = 310, P = 0.003), total cholesterol (β = 315, P = 0.002), BMI (β = 308, P = 0.002), HbA1c (β = 227, P = 0.018), and HOMA-IR (β = 184, P = 0.049) were independently correlated with EFT. CONCLUSIONS Although the number of patients included in this study is limited, high EFT results may indicate presence of atherosclerosis in women with previous GDM.

Abstract
PURPOSE OF REVIEW We comment on the associations between epicardial adiposity and cardiovascular disease (CVD) and associated risk factors. The effects of lifestyle measures and CVD drugs on cardiac adipose tissue are also discussed. RECENT FINDINGS Epicardial adipose tissue exerts cardioprotective properties; however, in cases of pathological enlargement, epicardial fat can lead to myocardial inflammation and dysfunction as well as left ventricular hypertrophy and coronary artery disease (CAD) due to paracrine actions that include increased production of reactive oxygen species, atherogenic and inflammatory cytokines. Cardiac adiposity is associated with CAD, obesity, type 2 diabetes, metabolic syndrome, nonalcoholic fatty liver disease, and chronic kidney disease, as well as with CVD risk factors such as lipids, hypertension, obesity markers, and carotid atherosclerosis. SUMMARY Due to its anatomical and functional proximity to the coronary circulation, epicardial adipose tissue may represent an even more direct CVD risk marker than central adiposity. Lifestyle measures and certain drugs may affect its thickness, although there are limited data currently available. The clinical implications of epicardial fat in daily practice remain to be established in future studies.

Abstract
AIMS In patients with hypertension (HT), increased aortic stiffness is related to higher cardiovascular morbidity and mortality. Recent investigations have shown that epicardial adipose tissue (EAT) is a new potential cardiometabolic risk factor. The aim of our study was to examine the relation between echocardiographically measured EAT thickness and aortic stiffness in patients with primary HT. METHODS The study included 144 newly diagnosed and untreated essential hypertensive outpatients. Transthoracic echocardiographic EAT thickness and aortic stiffness measurements were performed for all study participants. Afterwards patients were divided in two groups according to their median EAT thickness values. The patients with EAT thickness of < 7 mm were included in group 1 and patients with EAT thickness of ≥ 7 mm were included in group 2. RESULTS Aortic strain and distensibility parameters of group 2 were lower than in group 1. The aortic stiffness index of group 2 was found to be higher than group 1. Multivariate regression analysis revealed that EAT thickness was the only independent variable for all three parameters of aortic stiffness index, aortic strain and aortic distensibility. CONCLUSION In patients with newly diagnosed primary HT, increased EAT thickness was significantly linked to impaired aortic elastic properties independently of other conventional adiposity measurements.

Abstract
The main aim of the present study was to investigate the association between epicardial adipose tissue (EAT) and arterial function in patients with asymptomatic hypertension. Patients with hypertension (n = 155) were enrolled consecutively. Patients with decreased arterial compliance (AC) and increased cardioankle vascular index (CAVI) had higher EAT values compared with those with normal AC and CAVI (6.23 ± 1.67 vs 4.91 ± 1.40, P < .001 and 6.02 ± 1.61 vs 4.96 ± 1.46, P = .01, respectively). Analysis using the receiver-operating characteristics curve demonstrated that EAT 5.5 mm constitutes the cutoff value for the presence of increased CAVI with 67% sensitivity and 62% specificity (area under the curve [AUC]: 0.702, 95% confidence interval [CI] 0.590-0.814) and decreased AC with 77% sensitivity and 65% specificity (AUC: 0.756, 95% CI 0.645-0.867). Assessment of EAT during echocardiography examination may provide information on arterial function in patients with asymptomatic hypertension. The link between EAT and arterial stiffness deserves further investigation.

Abstract
AIM The cardio-ankle vascular index (CAVI) reflects arterial stiffness from the aorta to the ankle, independent of blood pressure (BP). We investigated the age-stratified CAVI in healthy, normotensive individuals to evaluate the effects of age on arterial stiffness. METHODS The CAVI and peripheral BP were determined in healthy, normotensive Koreans 20 to 79 years of age. The subjects had no history of cardiovascular disease and did not take any medications for hypertension, diabetes mellitus or dyslipidemia (N = 1,380; 44.1% in men). RESULTS The mean systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP) were 117, 75 and 42 mmHg, respectively. The CAVI increased linearly with age and was determined using the following equation: CAVI = 5.0 + 0.048 × age (year) in men (r(2) = 0.395, p < 0.001), CAVI = 4.8 + 0.045 × age (year) in women (r(2) = 0.450, p < 0.001). However, SBP, DBP and PP did not change progressively with age. Age emerged as the major determinant of the CAVI in a stepwise multiple regression analysis (r(2) change = 43.1%). CONCLUSIONS The CAVI scores increased with age in the healthy, normotensive individuals, whereas SBP, DBP and PP did not. Age was the dominant risk factor for the progression of arterial stiffness. These data suggest that the CAVI is a sensitive marker of the arterial aging process, above and beyond conventional upper arm BP.

Arterial stiffness has been identified as an independent predictor of prognostic outcomes for patients with cardiovascular disease. Although measurement of pulse wave velocity has been a widely accepted noninvasive approach to the assessment of arterial stiffness, its accuracy is hampered by changes in blood pressure. Taking the exponential relation between intravascular pressure and arterial diameter into consideration, a stiffness parameter can be obtained by plotting the natural logarithm of systolic–diastolic pressure ratio against the arterial wall extensibility. Cardio-ankle vascular index (CAVI), which is calculated based on the stiffness parameter thus obtained, is theoretically independent of changes in blood pressure. With this distinct advantage, CAVI has been widely applied clinically to assess arterial stiffness in subjects with known cardiovascular diseases including those with diagnosed atherosclerosis, coronary heart disease, and stroke as well as those at risk, including those with hypertension, diabetes, the elderly, and the obese. Because of its enhanced sensitivity, not only has the index been used to discern subtle changes in the disease process, it has also been utilized in studying normal individuals to assess their potential risks of developing cardiovascular diseases. The primary aims of assessing arterial stiffness using CAVI are not only to aid in early detection of arteriosclerosis to allow timely treatment and change in lifestyle, but also to quantitatively evaluate the progression of disease and the effectiveness of treatment. Despite its merit of being unaffected by blood pressure, discretion in data interpretation is suggested because an elevated CAVI represents not just vascular stiffness caused by pathological changes in the arterial wall, but can also be attributed to an increased vascular tone brought about by smooth muscle contraction. Moreover, certain patient populations, such as those with an ankle-brachial index < 0.9, may give falsely low CAVI and are suggested to be excluded from study.

Abstract
AIM The cardio-ankle vascular index (CAVI) reflects overall arterial stiffness from the aorta to the ankle, independent of blood pressure. Cerebral small vessel diseases (SVDs), including white matter lesions (WML), silent lacunar infarction (SLI) and cerebral microbleeds (CMB), are considered to increase the risk of stroke and cognitive impairment further. We aimed to investigate the association of cerebral SVD with CAVI in asymptomatic young and middle-aged subjects. METHODS Asymptomatic Korean individuals aged 30 to 59 years old without neurologic disease who had CAVI and brain magnetic resonance imaging (MRI) were evaluated retrospectively. RESULTS Among 484 subjects, cerebral SVDs (advanced WML, SLI and CMB) were found in 20 (4.1%). Subjects with SVDs tended to be older and to have higher systolic blood pressure (SBP) and higher CAVI. From multivariate regression analysis, including pulse pressure (PP) or SBP, CAVI showed a significant association with SVD [adjusted OR (95% CI): 1.889 (1.094-3.263), p= 0.002 and 1.793 (1.020-3.153), p= 0.043, for PP and SBP, respectively]. When CAVI was assessed by quartiles, the highest quartile of CAVI (CAVI >7.65) showed a significant association with SVD, after adjustment for PP [adjusted OR (95% CI): 2.766 (1.115-6.866), p= 0.028]. CONCLUSION In young and middle-aged subjects, cerebral SVD was significantly associated with arterial stiffness measured by CAVI after adjusting for PP or SBP.

Abstract
OBJECTIVE Epicardial adipose tissue (EAT) is proposed as a cardiovascular risk marker in non-uremic subjects. However, little is known about its role in patients with higher cardiovascular risk profile such as chronic kidney disease. The aim of this study was to investigate the relationship between EAT and several cardiovascular surrogate markers (coronary artery calcification (CAC), arterial stiffness and atherosclerosis) in patients on maintenance hemodialysis. METHODS A total of 191 prevalent hemodialysis patients were enrolled in this cross-sectional study. EAT and CAC scores (CACs) were determined by multi-slice computerized tomography, arterial stiffness by carotid-femoral pulse wave velocity (PWV), and carotid artery intima-media thickness (CA-IMT) by B-mode doppler ultrasonography. RESULTS Mean age was 59 ± 13 years and time on hemodialysis 75 ± 44 months. Twenty percent of the patients had diabetes. Mean EAT volume was 62.6 ± 26.8 cm(3)/m(2). Mean CA-IMT and PWV values increased across the EAT tertiles. EAT was correlated with age, female gender, body mass index, albumin and lipid parameters. Additionally, CA-IMT and PWV values were positively correlated with EAT. EAT volume was significantly higher in patients with CACs >10 compared to the patients with CACs ≤10. Despite the univariate associations between EAT and cardiovascular surrogate markers, only age, body mass index and total cholesterol levels were associated with EAT in adjusted models. CONCLUSIONS In prevalent hemodialysis patients, EAT is correlated with atherosclerosis, arterial stiffness and the presence of CAC. However, this correlation is not independent of other risk factors.
