Abstract
Background Carotid artery stiffness is associated with cognitive impairment and dementia, but the underlying mechanisms remain unknown. We examined the associations of carotid artery stiffness with cerebral small-vessel disease markers, cognition, and dementia subtypes in a memory clinic cohort. Methods and Results A total of 272 participants underwent carotid ultrasonography, 3 Tesla brain magnetic resonance imaging, and neuropsychological assessment. Carotid ultrasonography was used to assess β-index, pressure-strain elastic modulus, and pulse-wave velocity-β. Brain magnetic resonance images were graded for cerebral small-vessel disease markers, including white matter hyperintensities, lacunes, and cerebral microbleeds. Participants were classified as having no cognitive impairment, cognitive impairment and no dementia, or dementia subtyped as Alzheimer disease and vascular dementia. Cognition was assessed using National Institute of Neurological Disorders and Stroke-Canadian Stroke Network harmonization battery. After adjusting for age, sex, cardiovascular risk factors, and diseases, multivariable models showed that β-index (β=0.69; P=0.002), elastic modulus (β=0.78; P<0.001), and pulse-wave velocity-β (β=0.80; P<0.001) were associated with white matter hyperintensities, and elastic modulus (odds ratio [OR], 1.39 [95% CI, 1.04-1.85]) and pulse-wave velocity-β (OR, 1.47 [95% CI, 1.10-1.98]) were independently associated with lacunes. Similarly, β-index (OR, 2.04 [95% CI, 1.14-4.13]), elastic modulus (OR, 2.22 [95% CI, 1.25-4.42]), and pulse-wave velocity-β (OR, 2.50 [95% CI, 1.36-5.18]) were independently associated with vascular dementia. Carotid stiffness measures were independently associated with worse performance in global cognition, visuomotor speed, visuospatial function, and executive function. These associations became largely nonsignificant after further adjusting for cerebral small-vessel disease markers. Conclusions In memory clinic patients, carotid artery stiffness was associated with white matter hyperintensities and lacunes, impairment in global and domain-specific cognition, and causative subtypes of dementia, particularly vascular. The effects of carotid stiffness on cognition were not independent of, and were partially mediated by, cerebral small-vessel disease.

Abstract
Abstract
Objective. Arterial dispersion ultrasound vibrometry (ADUV) relies on the use of guided waves in arterial geometries for shear wave elastography measurements. Both the generation of waves through the use of acoustic radiation force (ARF) and the techniques employed to infer the speed of the resulting wave motion affect the spectral content and accuracy of the measurement. In particular, the effects of the shape and location of the ARF beam in ADUV have not been widely studied. In this work, we investigated how such variations of the ARF beam affect the induced motion and the measurements in the dispersive modes that are excited. Approach. The study includes an experimental evaluation on an arterial phantom and an in vivo validation of the observed trends, observing the two walls of the waveguide, simultaneously, when subjected to variations in the ARF beam extension (F/N) and focus location. Main results. Relying on the theory of guided waves in cylindrical shells, the shape of the beam controls the selection and nature of the induced modes, while the location affects the measured dispersion curves (i.e. variation of phase velocity with frequency or wavenumber, multiple modes) across the waveguide walls. Significance. This investigation is important to understand the spectral content variations in ADUV measurements and to maximize inversion accuracy by tuning the ARF beam settings in clinical applications.

Abstract
Background: Radiation-induced carotid artery disease (RICAD) is an important issue in head and neck cancer (HNC) survivors after radiotherapy (RT). The risk of cerebrovascular disease in these patients is doubled. The aim of this study was to assess the effect of RT on carotid artery stiffness in HNC patients. Patients and methods: Conventional arterial stiffness parameters were measured in a total of 50 HNC survivors treated with RT for at least 5 years and compared to 50 unirradiated HNC patients. Elastic modulus (Ep) and Beta stiffness index (β) were measured in proximal, mid and distal common carotid artery (CCA). Results: The mean age of the subjects was 68±9 years (range: 44-84) in the irradiated group and 67±10 years (range: 45-85) in the control group. The RT group was treated with a mean radiation exposure of 60.3±6.7 Gy (range: 44-72) in the neck. Carotid stiffness parameters showed significant group differences: Ep in the RT group was 2.329±1.222 vs 1.742±828 in the non-RT group (p=0.006) and β index in the RT group was 23±11 vs 15±8 in the non-RT group (p<0.001). Radiation-induced carotid stiffness was quantified and cervical exposure to RT increased Ep in 575 kPa (p=0.014) and β in 7 units (p<0.003). Conclusions: Ep and β index could be suitable ultrasound biomarkers of radiation-induced atherosclerosis in HNC survivors. Further prospective studies are needed to feature RICD in this setting.

Abstract
PURPOSE We aimed to evaluate the effectiveness of speckle tracking carotid strain (STCS) technique, which enables measurement of arterial stiffness and strain parameters, in the detection of early atherosclerotic findings in type 1 diabetes mellitus (T1DM). METHODS We prospectively enrolled 30 T1DM patients and 30 age- and sex-matched control participants with no history of cardiovascular disease. All study population underwent carotid ultrasonography. Radial and circumferential movement of the common carotid artery (CCA) in the transverse plane as the well as the radial movement of the CCA in the longitudinal plane were calculated automatically by using the STCS method. In addition, the strain (%), strain rate (per second), and peak circumferential and radial displacements (mm) were calculated. Arterial stiffness parameters, such as elastic modulus, distensibility, arterial compliance, and β-stiffness index, were calculated using the radial measurements. The mean value of the carotid intima media thickness (CIMT) was calculated semi-automatically for each CCA, in the longitudinal plane. We also analyzed the patients' overall body composition. RESULTS T1DM and control groups were compared in terms of strain and stiffness parameters and no statistically significant difference was found (p > 0.05). CIMT was higher in diabetic patients than in the control group (p = 0.039). In both groups, age was correlated with all arterial stiffness and strain parameters (p < 0.05). The duration of diabetes was also correlated with β-stiffness index, distensibility, and elastic modulus in the longitudinal plane (p < 0.05). In the diabetic group, abdominal fat ratio, whole body fat ratio, and fat mass were correlated with radial and circumferential displacement and strain parameters in transverse plane, and radial displacement in longitudinal plane (p < 0.05, for each). Diabetic patients were divided into subgroups according to the presence of nephropathy and dyslipidemia. Although no significant difference was found between the groups in terms of CIMT, patients with nephropathy had higher values for transverse and longitudinal elastic modulus, pulse-wave velocity, and longitudinal β-stiffness index, as well as lower values for longitudinal arterial compliance and distensibility, compared with patients without nephropathy (p < 0.05). Also, patients with dyslipidemia had higher longitudinal β-stiffness and elastic modulus values compared with patients without dyslipidemia (p < 0.05). CONCLUSION STCS ultrasonography is an effective, easy, and noninvasive method for evaluating the arterial elasticity. It may provide an early assessment of atherosclerosis in patients with T1DM, especially in the presence of nephropathy and dyslipidemia; thus, together with CIMT measurement, it may be used more frequently to detect subclinical damage and stratify atherosclerosis.

Abstract
OBJECTIVES To derive normative carotid artery stiffness data in rural adult Chinese population-based study of ultrasound measurements of carotid elasticity by using quality arterial stiffness (QAS), and to assess the changes of relevant parameters in Chinese adults 40 years of age and older. DESIGN A China stroke cohort study (total number: 1586) in the northern countryside were carried out between June 2013 and April 2016, designed to investigate the risk factors of cardiovascular and age-related diseases. SETTING The present study was a cross-sectional analysis of an ongoing community-based Shunyi cohort study in China. PARTICIPANTS A total of 583 participants (227 men and 356 women; aged 40-80 years) with ultrasound carotid QAS examination were retrieved from the study to analyse. PRIMARY AND SECONDARY OUTCOME MEASURES Arterial stiffness parameters included diastolic diameter (Dd), pulse wave velocity (PWV), stiffness indices α and β were calculated by QAS. Other clinical indicators included physical measurements, medical histories and blood biochemical test. RESULTS In the entire study sample, mean Dd was 7.93±0.88 mm, mean PWV was 9.4±2.4 m/s, mean α was 7.65±5.13 and mean β was 15.53±10.29. PWV was significant higher in participants with hypertension (9.9 m/s vs 9.2 m/s in those without, p=0.002), and with diabetes (10.3 m/s vs 9.2 m/s in those without, p=0.003). PWV were significantly higher in participants with HbA1c at 5.8%-6.4% versus <5.8%, but no difference was found between subjects with glycohaemoglobin (HbA1c) at 5.8%-6.4% versus >6.4% (p=0.005, p=0.955, respectively). Age increase by every 10 years was associated with Dd increased by 0.27 mm, PWV increased by 1.2 m/s, α increased by 1.34 and β increased by 2.71. Systolic blood pressure (SBP) increase by every 10 mm Hg was associated with Dd increased by 0.15 mm, PWV increased by 0.35 m/s, α increased by 0.13 and β increased by 0.15. CONCLUSION Among the participants older than 40 years, stiffness of the carotid artery had differences between hypertension and non-hypertension adults, as well as between diabetes and non-diabetes adults. Stiffness of the carotid artery also have differences between adults with HbA1c at 5.8%-6.4% versus <5.8%. Stiffness of the carotid artery increases with increasing age and increasing SBP at a range from 40 and up.

Abstract
Background: Acute rheumatic fever (ARF) is an important cause of valvular heart disease in children. Endothelial dysfunction plays an important role in the pathogenesis of valvular heart diseases. The role of endothelial dysfunction in valvular heart diseases due to ARF is not exactly known. In ARF, autoimmune injury, inflammation, oxidative stress, and impairment of nitric oxide in valvular endothelium may be the causes of endothelial dysfunction. The purpose of this study is to evaluate endothelial dysfunction and arterial stiffness in children with ARF. Materials and Methods: Thirty-six patients diagnosed with ARF (the mean age was 11.80 ± 2.82 years) and 36 volunteered individuals with similar age, sex, and body mass index were included in the study. The study groups were compared in terms of M-mode echocardiography parameters, carotid arterial strain (CAS), beta-stiffness index (βSI), and flow-mediated dilation (FMD). Results: In patients with ARF, there was a decrease in FMD% (10.36 ± 7.26 and 12.76 ± 4.59; P < 0.001) compared to the control group. In addition, CAS (0.16 ± 0.06 and 0.18 ± 0.08; P = 0.44) and βSI (3.65 ± 1.61 and 3.57 ± 2.38; P = 0.24) were similar in the patient and the control groups. Furthermore, no correlation was detected between decreased FMD value and mitral regurgitation (r = −0.07; P = 0.66), aortic regurgitation (r = −0.04; P = 0.78), CAS (r = −0.08; P = 0.61), and βSİ (r = −0.20; P = 0.22). Conclusion: In our study, a decrease in FMD value, which is a marker of endothelial dysfunction, was found in children with rheumatic carditis.

Abstract
BACKGROUND Interactions between the left ventricular (LV) and the arterial system, (ventricular-arterial coupling) are key determinants of cardiovascular function. However, most of studies covered multiple cardiovascular risk factors, which also contributed to the morphological and functional changes of LV. The aim of this study was to examine the relationship between arterial stiffness and LV structure and function in healthy women with a low burden of risk factors. METHODS Healthy women from the Twins UK cohort (n = 147, mean age was 54.07 ± 11.90 years) were studied. Arterial stiffness was evaluated by carotid-femoral pulse wave velocity (cf-PWV). LV structure and function were assessed by two-dimensional speckle tracking echocardiography. RESULTS cf-PWV was significantly associated with most measures of LV geometry and function, including relative wall thickness (RWT), E/e' ratio, global circumferential and radial strain, apical rotation and LV twist (each p < 0.05), but bore no relation to global longitudinal strain. After adjustment for age, body mass index, blood pressure and heart rate, cf-PWV was significantly correlated with RWT, global circumferential strain, apical rotation and LV twist (β = 0.011, - 0.484, 1.167 and 1.089, respectively, each p ≤ 0.05). CONCLUSIONS In healthy women with a low burden of risk factors, elevated arterial stiffness was intimately interwoven with increased LV twisting even before LV dysfunction becomes clinically evident.

Abstract
AIM We aimed to explore the relevance of multidirectional movements of the common carotid artery in atherothrombotic stroke. METHODS AND RESULTS We prospectively enrolled 69 patients with atherothrombotic stroke (stroke group) and 69 age-matched and sex-matched controls (control group) who underwent carotid ultrasonography. Based on the speckle tracking technique, circumferential and radial movements of the common carotid artery were analyzed from transverse and longitudinal B-mode images of the common carotid artery. Peak longitudinal and radial displacements, strain, and strain rate were measured. Mean age of the overall population was 64 ± 11 years, and 57% (78 patients) were men. In the transverse image, circumferential strain was significantly lower in the stroke group than in the control group (5.6 ± 1.6 vs 4.2 ± 1.7, P < .001). In multivariate logistic regression analysis, circumferential strain was independently associated with stroke (odds ratio: 0.60, P = .001). Compared with conventional risk factors, as well as carotid intima-media thickness and carotid plaque, the addition of a strain parameter appeared to improve discrimination of a stroke event (area under the receiver operating characteristic curve: 0.65 and 0.75 vs 0.84, respectively; P < .05 for both). CONCLUSIONS Circumferential strain of the common carotid artery might serve as a novel surrogate marker of atherothrombotic stroke. Multidirectional strain imaging of the common carotid artery may provide more information than conventional carotid ultrasonography and identify clinical risk factors for risk stratification of an acute stroke event.

The Value of Elastic Modulus Index as a Novel Surrogate Marker for Cardiovascular Risk Stratification by Dimensional Speckle-Tracking Carotid Ultrasonography.

Abstract
Background Carotid intima media thickness (CIMT) and the presence of carotid plaque have been used for risk stratification of cardiovascular disease (CVD). To date, however, the association between multi-directional functional properties of carotid artery and CVD has not been fully elucidated. We sought to explore the multi-directional mechanics of the carotid artery in relation to cardiovascular risk. Methods Four hundred one patients who underwent carotid ultrasound were enrolled between January 2010 and April 2013. A high risk of CVD was defined as more than 20% of 10-year risk based on the Framingham risk score. Using a speckle-tracking technique, the longitudinal and radial movements were analyzed in the B-mode images. Peak longitudinal and radial displacements, strain and strain rate were also measured. Beta stiffness and elastic modulus index were calculated from the radial measurements. Results Of the overall sample, 13% (52) of patients comprised the high-risk group. In multivariate logistic regression, CIMT and elastic modulus index were independently associated with a high-risk of CVD {odds ratio (OR): 1.810 [95% confidence interval (CI) 1.249–2.622] and OR: 1.767 (95% CI: 1.177–2.652); p = 0.002, 0.006, respectively}. The combination of CIMT and elastic modulus index correlated with a high-risk of CVD more so than CIMT alone. Conclusion The elastic modulus index of the carotid artery might serve as a novel surrogate marker of high-risk CVD. Measurement of the multi-directional mechanics of the carotid artery using the speckle tracking technique has potential for providing further information over conventional B-mode ultrasound for stratification of CVD risk.

Evaluation of carotid intima-media thickness and carotid arterial stiffness in children with adenotonsillar hypertrophy. World J Pediatr 2016; 12:103-8. [PMID: 26684310 DOI: 10.1007/s12519-015-0066-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2014] [Accepted: 10/15/2014] [Indexed: 01/13/2023]
Abstract
BACKGROUND Adenotonsillar hypertrophy can produce cardiopulmonary disease in children. However, it is unclear whether adenotonsillar hypertrophy causes atherosclerosis. This study evaluated carotid intimamedia thickness and carotid arterial stiffness in children with adenotonsillar hypertrophy. METHODS The study included 40 children with adenotonsillar hypertrophy (age: 5-10 years) and 36 healthy children with similar age and body mass index. Systolic blood pressure, diastolic blood pressure, and pulse pressure were measured in all subjects. Carotid intima-media thickness, carotid arterial systolic diameter, and carotid arterial diastolic diameter were measured using a high-resolution ultrasound device. Based on these measurements, carotid arterial strain, carotid artery distensibility, beta stiffness index, and elasticity modulus were calculated. RESULTS Carotid intima-media thickness was greater in children with adenotonsillar hypertrophy (0.36±0.05 mm vs. 0.34±0.04 mm, P=0.02) compared to healthy controls. Beta stiffness index (3.01±1.22 vs. 2.98±0.98, P=0.85), elasticity modulus (231.39±99.23 vs. 226.46±83.20, P=0.88), carotid arterial strain (0.17±0.06 vs. 0.17±0.04, P=0.95), and carotid artery distensibility (13.14±3.88 vs. 12.92±3.84, P=0.75) were similar between children with adenotonsillar hypertrophy and the healthy controls. CONCLUSIONS The present study revealed increased carotid intima-media thickness in children with adenotonsillar hypertrophy. The risk of subclinical atherosclerosis may be higher in children with adenotonsillar hypertrophy.

Abstract
Increased carotid stiffness and impaired brachial artery flow-mediated dilatation (FMD) associate with cardiovascular events. We have previously reported three FMD patterns based on the time of maximal dilatation. The aim of the present study was to verify whether different FMD patterns associate with carotid artery stiffness. In all, 133 subjects were enrolled. All participants underwent complete clinical examination, blood sampling and ultrasound study. FMD was used as a measure of endothelial function. Based on the maximal brachial artery FMD, subjects were divided into Early dilators (peak FMD at 50 s), Late dilators (peak FMD over 50 s) and No dilators. Echo-Doppler evaluation of carotid arteries was performed in order to calculate elastic indexes (strain, β-stiffness index and distensibility). In all, 64 subjects were classified as Early FMD, 36 as Late FMD and 33 as No dilators. Age, gender and cardiovascular risk factors were comparable among three groups. Early FMD had higher values of strain compared with both Late and no Dilators (P<0.001). Furthermore, Early dilators showed a significantly lower stiffness and higher distensibility compared with Late and No dilators. No significant differences between Late FMD and No Dilators were detected. Our results demonstrate that common carotid artery elasticity indexes significantly differ among Early, Late and No dilators. Subjects with delayed or absent brachial artery dilatation have stiffer common carotid arteries compared with subjects with early dilatation. In conclusion, our research suggests that the assessment of the kinetics of FMD in a clinical setting might represent a useful screening tool to improve the cardiovascular risk stratification.

Abstract
AIMS A relationship between arterial stiffening and coronary flow abnormalities, although not fully elucidated, has been observed. The purpose of this study was to investigate the relationship among carotid stiffness, measured using echo-tracking, and Doppler parameters of coronary blood flow, sampled at the left anterior descending (LAD) artery. METHODS We studied 88 consecutive patients (49 men, mean age 51.2 ± 16.2 years) with cardiovascular risk factors but without history of cardiovascular diseases. Each patient underwent echocardiographic evaluation for measurement of the diastolic velocity time integral (DVTI) and calculation of the diastolic velocity time integral coronary index (DVTICI), the ratio between DVTI and total velocity time integral of LAD artery flow × 100, and carotid ultrasound for measurement of carotid intima media thickness (IMT) and stiffness parameters such as β index and elastic modulus (Ep). RESULTS DVTICI was significantly greater in men than in women (median 82, interquartile range 78-86 vs. median 80, interquartile range 73-83, respectively; P < 0.016). After correlating DVTICI with other variables, a significant inverse relation was obtained with β index (Rho = -0.449, P < 0.001), Ep (Rho = -0.478, P < 0.001), age (Rho = -0.52, P < 0.001), left ventricular mass index (Rho = -0.543, P < 0.001), E/E' (Rho = -0.411, P < 0.001), pulse pressure (Rho = -0.417, P < 0.001) and IMT (Rho = -0.480, P < 0.001). With linear multiple regression analysis, only β index (P < 0.001), Ep (P < 0.001), male sex (P < 0.001) and left ventricular mass index (P = 0.008) were independently associated with reduction of DVTICI. CONCLUSION Increased arterial stiffness, directly affecting coronary perfusion, is associated with reduced diastolic coronary flow. Echo-tracking for feasible measurement of carotid artery stiffness parameters may be valuable in more accurate cardiovascular risk stratification.

Abstract
Arterial stiffness is thought to be a precursor to atherosclerosis. Conventional arterial stiffness parameters as potential biomarkers of radiation-induced damage were investigated. Patients with head and neck cancer treated with radiotherapy ≥2 years previously to one side of the neck were included. The unirradiated side was the internal control. Beta stiffness index (B) and elastic modulus (Ep) were used to assess arterial stiffness and were measured in proximal, mid, and distal common carotid artery (CCA) and compared with the corresponding unirradiated segments. Fifty patients (68% male; median age 58 years; interquartile range 50-62) were included. Mean ± standard deviation maximum doses to irradiated and unirradiated arteries were 53 ± 13 and 1.9 ± 3.7 Gy, respectively. Differences in B were not significant. Significant differences in Ep were demonstrated-proximal CCA: 1301 ± 1223 versus 801 ± 492 (P < .0001), mid CCA: 1064 ± 818 versus 935.5 ± 793 (P < .0001), and distal CCA: 1267 ± 1084 versus 775.3 ± 551.9 (P < .0001). Surgery had no impact on arterial stiffness. Arterial stiffness is increased in irradiated arteries, in keeping with radiation-induced damage. Prospective data may show an association between arterial stiffness and atherosclerosis in this setting.

Abstract
The pathophysiology of ischemic leukoaraiosis (ILA) is unknown. It was recently found that ILA patients have increased aortic stiffness. Carotid stiffness is a more specific parameter and could have value as a non-invasive diagnostic value for ILA. Therefore, using color-coded duplex sonography, we compared local carotid stiffness parameters of 59 patients with ILA with those of 45 well-matched controls. The diagnosis of ILA was based on exclusion of other causes of white matter changes seen on magnetic resonance imaging. Pulse wave velocity β (PWVβ, m/s), pressure-strain elasticity modulus (Ep, kPa), β index and augmentation index (Aix, %) values were higher and arterial compliance (AC, mm(2)/kPa) values were lower in the ILA group; however, only Ep and PWVβ reached statistical significance (p ≤ 0.05). β, Ep and PWVβ exhibited an increasing trend with higher Fazekas score, though only Ep reached significance (p = 0.05). The main conclusion was that Ep and PWVβ could have a diagnostic role in patients with ILA.

Abstract
AIMS Proximal aortic stiffness may be more important than carotid-femoral pulse wave velocity (cf-PWV) in the pathogenesis of heart failure. The present study investigated the associations of common carotid artery (CCA) stiffness, which might be a surrogate for proximal aortic stiffness, with left ventricular (LV) structure and function, and the development of acute heart failure (AHF). METHODS AND RESULTS Outpatients without a history of heart failure (114 subjects aged 63.5 ± 17.5 years) were enrolled for comprehensive noninvasive cardiovascular examinations. The LV mass index, the LV ejection fraction (EF), and the ratio of the early diastolic transmitral flow velocity to the early septal mitral annular diastolic velocity (E/E') were measured by echocardiography. CCA mechanical properties, including the incremental elastic modulus (Einc), β stiffness index, CCA distensibility (CD) and circumferential strain (CS), were assessed by carotid artery ultrasonography. cf-PWV was measured by arterial tonometry. CD was significantly associated with the LV mass index, and all CCA stiffness indices were significantly associated with EF and E/E' independently of age, mean blood pressure, and cf-PWV. During a mean follow-up of 265 ± 106 days, 9 patients presented with AHF. Einc (hazard ratio 6.56, 95% confidence interval 1.64-26.26, by quartile analysis), CS (6.82, 1.70-27.35), and β stiffness index (3.91, 1.05-14.57) but not cf-PWV (1.62, 0.41-6.51) significantly predicted the events. CONCLUSIONS In patients at risk for heart failure, CCA stiffness was significantly associated with LV structure and function independently of cf-PWV. In addition, CCA stiffness but not cf-PWV predicted first AHF.

Abstract
BACKGROUND Type 2 diabetes is one of the most common causes of cardiovascular disease as it causes arterial stiffness changes. The purpose of this study is to characterize, in vivo, carotid arterial structural and functional changes by applying radio frequency and X-strain ultrasound techniques. METHODS Ninety-one subjects were assigned into two groups; a diabetes group and a control group. Structural and functional changes in the common carotid arterial wall were investigated by quality intima-media thickness (QIMT), quality arterial stiffness (QAS), and X-strain analysis with a Mylab Twice ultrasound instrument. The relationships among variables between the two groups were analyzed in this study. RESULTS There was no significant difference in carotid IMT (626.5 ± 169.1 μm vs. 568.5 ± 122.6 μm, P = 0.1506) between two groups. Pulse wave velocity (PWV) and stiffness index (β) were remarkably greater (8.388 ± 3.254 m/s vs. 7.269 ± 1.332 m/s; 12.51 ± 14.16 vs.9.279 ± 2.871), while compliance coefficient (CC) decreased significantly in the diabetes group (0.802 ± 0.3094 mm2/Kpa vs. 0.968 ± 0.3992 mm2/Kpa) (P < 0.05). The displacement difference of radial (RD-D), longitudinal (LD-D) and rotation (ROT-D) directions were significantly different between two groups' comparison (P = 0.0212, P = 0.0235 and P = 0.0072, respectively). The time of circumferential peak strain difference (CS-DT) and the time of radial peak strain rate (RSR-T) were found to be significantly different between the two groups (341.9 ± 77.56 ms vs. 369.0 ± 78.26 ms, P = 0.0494; 142.7 ± 22.43 ms vs. 136.2 ± 30.70 ms, P = 0.0474). CS-TD and RSR-T were also found to be positively correlated with CC value (r = 0.3908, P < 0.005 and r = 0.3027, P = 0.0326, respectively). Finally, PWV was negatively correlated with CC with (r = -0.6177, P < 0.001). CONCLUSIONS In type 2 diabetes, the functional changes in CCA can be identified using the methods presented in this article earlier than the structural changes. Arterial stiffness values provided by QAS and X-strain analysis can be used as indicators of CCA functional lesions in patients with type 2 diabetes.

Abstract
Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) constitute important public health problems in developing countries. Inflammation is present both in the early and late stages of the diseases. Chronic inflammation is known to be associated with atherosclerosis. We hypothesize that subclinical atherosclerosis and arterial stiffness may increase due to the ongoing inflammation as well as the increased pulse pressure and left-ventricular systolic dysfunction in RHD. The purpose of the present study was to investigate carotid intima media thickness (CIMT) and carotid artery stiffness in patients with ARF. Forty patients in follow-up due to ARF in the age group of 7-16 years (disease duration 1-10 years) and 36 volunteered subjects with similar body mass index were included in the study. The subjects included in the present study were compared regarding M-mode echocardiographic parameters and CIMT as well as carotid arterial strain (CAS), carotid artery distensibility (CAD), beta stiffness index (βSI), and pressure-strain elasticity modulus (Ep) as carotid artery stiffness parameters. CIMT (0.52 ± 0.08 and 0.48 ± 0.07 mm, p = 0.01), βSI (5.29 ± 2.98 and 3.02 ± 1.30, p < 0.001), and Ep (426.53 ± 210.50 and 254.44 ± 104.69 p < 0.001) were increased, whereas CAS (0.11 ± 0.01 and 0.19 ± 0.09, p < 0.001) and CAD (10.27 ± 4.69 and 17.76 ± 14.41, p < 0.001) were decreased in patients with ARF compared with the control group. There was a positive correlation between pulse pressure and βSI (r = 0.25, p = 0.02) and Ep (r = 0.28, p = 0.01) in addition to a correlation between left atrial dilatation and CIMT (r = 0.55 p < 0.001) in patients with ARF. CIMT and carotid artery stiffness were increased in patients with ARF. Patients with ARF may have an increased risk of subclinical atherosclerosis and cardiovascular events.

Abstract
OBJECTIVES To examine the correlation between metabolic syndrome (MS), plasma total homocysteine (tHcy) level, and serum B vitamin levels on carotid intima-media thickness (CIMT) in hypertensive patients. METHODS A total of 73 medically treated hypertensive patients (42 men, mean age 70.7 years), fasted for 10 hours, and provided fasting blood samples for measurement of plasma tHcy, serum folic acid, and serum vitamin B12 levels. Additionally, B-mode ultrasound of the distal right common carotid arteries was performed on all participants. RESULTS There were 50 patients with and 23 patients without MS. Patients with MS had larger CIMT than patient without (0.81 ± 0.13 vs. 0.74 ± 0.10 mm, p = 0.018). Patients with MS had larger waist circumference (p < 0.001), higher body mass index (p < 0.001), elevated serum triglyceride level (p < 0.001), lower serum high density lipoprotein level (p = 0.016), higher prevalence of diabetes mellitus (p = 0.012), higher prevalence of hyperlipidemia (p = 0.019), and a higher prevalence of fibrate usage (p = 0.025) than patients without MS. In univariate analysis, CIMT correlated significantly with the presence of MS (r = 0.256; p = 0.029), usage of angiotensin receptor blocker (ARB; r = -0.256; p = 0.029), and male gender (r = 0.247; p = 0.035). The relationships between CIMT and serum folic acid level (r = -0.212; p = 0.072) or statin usage (r = 0.207; p = 0.079) were borderline significant. In multivariate regression analysis, after adjusting for age and gender, only usage of ARB (β value -0.078, 95% CI: -0.140 to -0.015, p = 0.016) and the presence of MS (β value 0.075, 95% CI: 0.020 to 0.131, p = 0.009) were associated with CIMT. In anothermodel, after adjusting four additional parameters including age, gender, systolic blood pressure and usage of statin, usage of ARB (β value -0.074, 95% CI: -0.137 to -0.011, p = 0.022) and presence of MS (β value 0.069, 95% CI: 0.012 to 0.125, p = 0.017) remained significantly correlated with CIMT. CONCLUSION MS and usage of ARB are associated with CIMT in hypertensive patients. KEY WORDS Folic acid; Homocysteine, Intima-media thickness, Metabolic syndrome.
