Abstract
The significance of atherosclerotic calcified lesions observed on low-dose computed tomography (LDCT) performed during general checkups was investigated. The coronary arteries (CA), ascending aorta and aortic arch (AAAA), descending thoracic aorta (DTA), and abdominal aorta (AA) were examined. Semiquantitative calcified index analysis of the DTA and AA in terms of atherosclerosis risk factors and cardio-ankle vascular index (CAVI) measurements was also performed. We included 1594 participants (mean age: 59.2 years; range: 31-91 years). The prevalence of calcified lesions was 71.0%, 66.6%, 57.2%, and 37.9% in the AA, CA, AAAA, and DTA, respectively. Age-related advances in calcification among participants with no major risk factors, revealed that calcification appeared earliest in the AA, followed by the CA, AAAA, and DTA. Participants with calcified lesions in all arteries had a significantly greater CAVI than those without calcification. The CAVI was negatively correlated with low-density lipoprotein cholesterol levels, particularly in participants without calcified lesions in the DTA. Calcified lesions on LDCT could indicate the end stage of atherosclerotic lesions. The CAVI can be used to assess atherosclerotic changes at all stages of disease progression. A combination of LDCT and CAVI could be used as a routine non-invasive assessment of atherosclerosis.

Abstract
OBJECTIVE The association of childhood blood pressure (BP) and heart rate (HR) with intermediate markers of cardiovascular disease several decades later has been shown, but studies on more short-term outcomes are scarce. Using population-based data, this study investigates the association of four BP parameters and HR in childhood with three carotid markers for vascular remodeling one decade later. METHODS At the 11-year follow-up, 4607 participants of the nationwide KiGGS cohort aged 14 to 28 years had semi-automated sonographic carotid intima media thickness (CIMT) measurements. We investigated associations of baseline (age 3-17 years) and follow-up SBP, DBP, mean arterial pressure (MAP), pulse pressure (PP) and resting heart rate (RHR), with CIMT and lumen diameter at or above the 90th percentile and distensibility coefficient at or below the tenth percentile in logistic regressions. Analyses were further adjusted using a composite cardiovascular risk (CVR) score of BMI, triglycerides, total/HDL-cholesterol-ratio and HbA1c. RESULTS SBP, DBP, MAP and RHR were significantly and similarly associated with all carotid measures 11 years later, for example an odds ratio (OR) of 1.17 [confidence interval (CI) 1.06-1.29] for one standard deviation SBP increase with elevated CIMT when adjusting for sex, age and CVR score. Cross-sectionally, the strongest association was found for MAP with reduced distensibility coefficient (OR 1.76; CI 1.59-1.94). CONCLUSION This population-based cohort study shows robust and consistent associations between childhood BP and RHR and three carotid measures of vascular remodeling only one decade later, clearly underscoring the potential importance of preventing high BP already early in the life course.

Cardiovascular Risk in Childhood is Associated With Carotid Intima-Media Thickness and Stiffness in Adolescents and Young Adults: The KiGGS Cohort. J Adolesc Health 2024; 74:123-129.

Abstract
PURPOSE Cardiovascular risk factors are widespread among children and adolescents and may lead to accelerated vascular aging in middle adulthood. However, data are scarce on shorter-term consequences, for example, on associated distinctive vascular properties before age 30 years. This study analyzes the association of childhood exposure to cardiovascular risk factors with carotid properties in adolescents and young adults. METHODS Four thousand thirty one participants from the population-based German Health Interview and Examination Survey for Children and Adolescents cohort (aged 3-17 years) had carotid intima-media thickness (CIMT) and distensibility coefficient (DC) measurements at the second follow-up (aged 14-28 years). The assessment of cardiovascular risk factors at baseline included information about arterial hypertension, obesity, dyslipidemia, and passive smoking. RESULTS Single risk factors and the exposure to multiple cardiovascular risk factors were associated with elevated CIMT and decreased DC. Relative risks for CIMT ≥ 90th centile and/or DC ≤ 10th centile were increased in participants exposed to two (RRCIMT = 1.45 [95% confidence interval 1.11-1.91], p < .05; RRDC = 1.37 [1.02-1.84], p < .05) and ≥ three risk factors (RRCIMT = 1.66 [1.05-2.62], p < .05; RRDC = 1.25 [0.71-2.21], p > .05). DISCUSSION Exposure to multiple cardiovascular risk factors starting in childhood is associated with measurably increased CIMT and carotid stiffness in late adolescence and early adulthood. These findings underline the importance of population-wide preventive measures to promote optimal cardiovascular health.

Maximum carotid intima-media thickness and NT-pro BNP in association with retinal vein occlusion. PLoS One 2023; 18:e0291456. [PMID: 38096214 PMCID: PMC10721079 DOI: 10.1371/journal.pone.0291456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 08/30/2023] [Indexed: 12/17/2023] Open
Abstract
The purpose is to clarify the relationship between patients with retinal vein occlusion (RVO), maximal intima-media complex thickness (Max IMT), and N-terminal pro-brain natriuretic peptide (NT-proBNP), which is useful in assessing atherosclerosis. This was a retrospective observation, single center study. The patients were 86 RVO patients (male: female = 43:43, mean age 63.3 years), 25 with central retinal vein occlusion (CRVO) and 61 with branch retinal vein occlusion (BRVO), classified as ≧50 years old and <50 years old, Max IMT≧1.1 and less, NT-pro BNP≧55 and less. Results showed that Max IMT ≧1.1 was significantly more common in both the CRVO and BRVO groups at ≧50 years, and NT-pro BNP ≧55 was significantly more common in the CRVO group. Max IMT≧1.1 was seen in 80% of the BRVO group and in 85% of patients aged ≧50 years. Sixty-eight percent of patients in the CRVO group had Max IMT≧1.1, but none of those < 50 years had Max IMT≧1.1. Forty-eight percent of RVO patients had NT-pro BNP≧55, and significantly more patients had Max IMT≧1.1 than those who did not have NT-pro BNP more than 55 (p = 0.02). Multiple regression analysis with Max IMT as the dependent variable showed that age and NT-pro BNP were significantly associated with RVO (p = 0.015, 0.022). RVO patients were more likely to have a Max IMT≧1.1, which was associated with atherosclerosis. Max IMT and NT-pro BNP were also associated with RVO patients, so NT-pro BNP may be a marker of RVO.

Abstract
Prevention of cardiovascular disease (CVD) remains one of the largest public health challenges of our time. Identifying individuals at increased cardiovascular risk at an asymptomatic, sub-clinical stage is of paramount importance for minimizing disease progression as well as the substantial health and economic burden associated with overt CVD. Vascular ageing (VA) involves the deterioration in vascular structure and function over time and ultimately leads to damage in the heart, brain, kidney, and other organs. Vascular ageing encompasses the cumulative effect of all cardiovascular risk factors on the arterial wall over the life course and thus may help identify those at elevated cardiovascular risk, early in disease development. Although the concept of VA is gaining interest clinically, it is seldom measured in routine clinical practice due to lack of consensus on how to characterize VA as physiological vs. pathological and various practical issues. In this state-of-the-art review and as a network of scientists, clinicians, engineers, and industry partners with expertise in VA, we address six questions related to VA in an attempt to increase knowledge among the broader medical community and move the routine measurement of VA a little closer from bench towards bedside.

Vascular Aging: Assessment and Intervention. Clin Interv Aging 2023; 18:1373-1395.

Abstract
Vascular aging represents a collection of structural and functional changes in a blood vessel with advancing age, including increased stiffness, vascular wall remodeling, loss of angiogenic ability, and endothelium-dependent vasodilation dysfunction. These age-related alterations may occur earlier in those who are at risk for or have cardiovascular diseases, therefore, are defined as early or premature vascular aging. Vascular aging contributes independently to cardio-cerebral vascular diseases (CCVDs). Thus, early diagnosis and interventions targeting vascular aging are of paramount importance in the delay or prevention of CCVDs. Here, we review the direct assessment of vascular aging by examining parameters that reflect changes in structure, function, or their compliance with age including arterial wall thickness and lumen diameter, endothelium-dependent vasodilation, arterial stiffness as well as indirect assessment through pathological studies of biomarkers including endothelial progenitor cell, lymphocytic telomeres, advanced glycation end-products, and C-reactive protein. Further, we evaluate how different types of interventions including lifestyle mediation, such as caloric restriction and salt intake, and treatments for hypertension, diabetes, and hyperlipidemia affect age-related vascular changes. As a single parameter or intervention targets only a certain vascular physiological change, it is recommended to use multiple parameters to evaluate and design intervention approaches accordingly to prevent systemic vascular aging in clinical practices or population-based studies.

Cadmium, von Willebrand factor and vascular aging. NPJ AGING 2023; 9:11.

Abstract
Vascular aging is a major contributing factor to cardiovascular disease. The aged blood vessels, characterized by vascular wall thickening and stiffening, are instigated by endothelial cell dysfunction induced by oxidative stress and inflammation. von Willebrand Factor (vWF) is a glycoprotein known for its role in coagulation, and plasma levels of vWF are increased with age. Elevated vWF promotes thrombosis, atherosclerotic plaque formation, inflammation and proliferation of vascular smooth muscle cells. Cadmium (Cd) is an environmental pollutant associated with increased morbidity and mortality of cardiovascular disease. At low concentrations, Cd activates pro-survival signaling in endothelial cells, however enhances intima-media thickness and atherogenesis. A non-cytotoxic dose of Cd also increases endothelial vWF expression and secretion in vivo and in vitro. In this review, we summarize the molecular mechanisms underlying vWF-promoted vascular aging-associated pathologies and Cd-induced vWF expression. In addition, we propose that exposure to low-dose Cd is a risk factor for vascular aging, through elevation of plasma vWF.

Abstract
Aging biomarkers are a combination of biological parameters to (i) assess age-related changes, (ii) track the physiological aging process, and (iii) predict the transition into a pathological status. Although a broad spectrum of aging biomarkers has been developed, their potential uses and limitations remain poorly characterized. An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research: How old are we? Why do we get old? And how can we age slower? This review aims to address this need. Here, we summarize our current knowledge of biomarkers developed for cellular, organ, and organismal levels of aging, comprising six pillars: physiological characteristics, medical imaging, histological features, cellular alterations, molecular changes, and secretory factors. To fulfill all these requisites, we propose that aging biomarkers should qualify for being specific, systemic, and clinically relevant.

Arterial myogenic response and aging. Ageing Res Rev 2023; 84:101813.

Abstract
The arterial myogenic response is an inherent property of resistance arteries. Myogenic tone is crucial for maintaining a relatively constant blood flow in response to changes in intraluminal pressure and protects delicate organs from excessive blood flow. Although this fundamental physiological phenomenon has been extensively studied, the underlying molecular mechanisms are largely unknown. Recent studies identified a crucial role of mechano-activated angiotensin II type 1 receptors (AT1R) in this process. The development of myogenic response is affected by aging. In this review, we summarize recent progress made to understand the role of AT1R and other mechanosensors in the control of arterial myogenic response. We discuss age-related alterations in myogenic response and possible underlying mechanisms and implications for healthy aging.

Abstract
INTRODUCTION Radiation-induced carotid artery stenosis (RI-CS) is known as one of long-term side effects of radiotherapy for head and neck cancer (HNC). However, the clinical time course after irradiation has been poorly understood. We aimed to investigate the natural history of radiation-induced carotid atherosclerosis, comparing the patients who received radiotherapy for HNC with the patients who were treated without radiotherapy. METHODS The patients who received treatment of HNC at Department of Otolaryngology, Head and Neck Surgery of Kyoto University Hospital, from November 2012 to July 2015 were enrolled. The patients were assigned into the RT group and the control group, depending on whether radiotherapy was planned or not. Annual carotid ultrasound was performed from the enrollment to 5 years. The increase of mean intima-media thickness (IMT) at common carotid artery from the enrollment (Δmean IMT) was evaluated. RESULTS Fifty-six patients in the RT group and 25 patients in the control group were enrolled. From 5-year follow-up data, the significant higher increase of Δmean IMT was consistently observed in the RT group than in the control group after 2 years. The RT group presented a 7.8-fold increase of mean IMT compared to the control group (0.060 mm per year in the RT group and 0.008 mm per year in the control group). Cumulative incidence curves obtained from the analysis of all vessels revealed that the RT group presented higher incidence of Δmean IMT ≥0.25 mm than the control group (p < 0.01). In the RT group, the patients with mean IMT ≥1.0 mm at enrollment exhibited significantly higher incidence of Δmean IMT ≥0.25 mm than the patients with mean IMT <1.0 mm (p < 0.01). DISCUSSION Radiotherapy for HNC induces continuous carotid mean IMT progression. The irradiated carotid arteries with mean IMT ≥1.0 mm before radiotherapy presented earlier IMT progression than those with mean IMT <1.0 mm.

Abstract
Objective. To evaluate the association between anti-phosphatidylethanolamine (aPE) and anti-phosphatidylserine (aPS) antibodies and cardiovascular risk, organ involvement and disease activity in systemic lupus erythematosus (SLE) patients. Methods. We studied 93 SLE patients and 30 controls. We analyzed levels of anti-phospholipid antibodies, including aPS and aPE, the profiles of antinuclear, anti-neutrophil cytoplasmic (ANCA) and anti-endothelial antibodies, carotid intima-media thickness (cITM) and atherosclerotic plaque presence, ankle-brachial and high resistance indices, atherosclerotic risk factors, organ manifestations and treatment. Results. Levels of aPS and aPE were significantly higher in SLE patients in comparison with the controls (p = 0.038 and p = 0.044, respectively). aPS was associated with the risk of Raynaud’s phenomenon (p = 0.021) development. aPE increased the risk of renal involvement (p = 0.049), cerebral stroke (p = 0.050), high vlues of cIMT (p = 0.041) development as well as occurrence of selected serological markers associated with activity of the disease such as anti-double stranded DNA (p = 0.021). The long duration of regular smoking (p = 0.021) and the high number of cigarettes/day (p = 0.015) were significantly associated with the risk of aPE occurrence. Conclusions. Patients with aPS and aPE are at risk of vascular involvement. Especially the presence of aPE may significantly increase the risk of thrombotic complications development in SLE patients without classical serological markers of APS. Finally, aPE might be used as a marker of disease activity and risk of renal injury development in this patient group. The classical atherosclerotic markers including lipid indices play an important role in complex analysis of cardiovascular risk in lupus patients and enable to identify patients at the highest risk and implement effective preventive, diagnostic and therapeutic procedures.

Chronological attenuation of NPRA/PKG/AMPK signaling promotes vascular aging and elevates blood pressure. Aging Cell 2022; 21:e13699.

Abstract
Hypertension is common in elderly population. We designed to search comprehensively for genes that are chronologically shifted in their expressions and to define their contributions to vascular aging and hypertension. RNA sequencing was conducted to search for senescence-shifted transcripts in human umbilical vein endothelial cells (HUVECs). Small interfering RNA (siRNA), small-molecule drugs, CRISPR/Cas9 techniques, and imaging were used to determine genes' function and contributions to age-related phenotypes of the endothelial cell and blood vessel. Of 25 genes enriched in the term of "regulation of blood pressure," NPRA was changed most significantly. The decreased NPRA expression was replicated in aortas of aged mice. The knockdown of NPRA promoted HUVEC senescence and it decreased expressions of protein kinase cGMP-dependent 1 (PKG), sirtuin 1 (SIRT1), and endothelial nitric oxide synthase (eNOS). Suppression of NPRA also decreased the phosphorylation of AMP-activated protein kinase (AMPK) as well as the ratio of oxidized nicotinamide adenine dinucleotide (NAD+ )/reduced nicotinamide adenine dinucleotide (NADH) but increased the production of reactive oxygen species (ROS). 8-Br-cGMP (analog of cGMP), or AICAR (AMPK activator), counteracted the observed changes in HUVECs. The Npr1+/- mice presented an elevated systolic blood pressure and their vessels became insensitive to endothelial-dependent vasodilators. Further, vessels from Npr1+/- mice increased Cdkn1a but decreased eNos expressions. These phenotypes were rescued by intravenously administrated 8-Br-cGMP and viral overexpression of human PKG, respectively. In conclusion, we demonstrate NPRA/PKG/AMPK as a novel and critical signaling axis in the modulation of endothelial cell senescence, vascular aging, and hypertension.

Abstract
The velocity of propagation of pulse waves through the arteries is one of the indicators of the health of the cardiovascular system. By measuring the pulse wave velocity, cardiologists estimate the elasticity of the blood vessel walls and the changes that occur with aging. When the Moens-Korteweg equation is used in analysis, it leads to an erroneous assessment. This paper presents the solution of Navier-Stokes equations for propagation of pulse waves through an elastic tube filled with viscous fluid under initial pressure. The equation for pulse wave velocity depending on viscosity, density and initial fluid pressure, density and elasticity of the wall and geometry of the tube is derived. The results of the equation were compared with experimental results measured using a biophysical model of the cardiovascular system.

Abstract
Scientific evidence has shown that physical exercise is an effective way of improving several cardiovascular disease markers. However, few studies have tested its effectiveness when performed in aquatic environments. The purpose of this study was to test the impact of different aquatic exercise programs on the intima-media thickness of carotid arteries (IMT) and hemodynamic and biochemical markers of cardiovascular diseases in community-dwelling older persons. A total of 102 participants were randomly allocated into four groups: an aerobic exercise group (AerG) (n = 25, 71.44 ± 4.84 years); an aerobic interval group (IntG) (n = 28, 72.64 ± 5.22 years); a combined group (ComG) (n = 29, 71.90 ± 5.67 years); and a control group (CG) (n = 20, 73.60 ± 5.25 years). The AerG, IntG, and ComG participants took part in three different aquatic exercise programs for 28 weeks. The CG participants maintained their usual routines. All participants were evaluated for IMT, blood pressure, lipid profile, and MCP-1 and MIP-1α chemokines, pre- and post-intervention. Significant differences were found in the AerG for diastolic diameter (DD), in the IntG for peak systolic velocity (PSV), and in the ComG for DD and end-diastolic velocity (EDV). Regarding blood pressure, significant differences were found in AerG for systolic blood pressure (SBP) and diastolic blood pressure (DBP); in IntG for DBP; and in ComG for SBP, DBP, and heart rate (HR). Significant differences were found in the AerG and IntG for glucose (GLU). Lower plasma levels of monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein (MIP-1α) were found in the AerG and in the ComG for MCP-1 after the intervention. Aquatic physical exercise appears to improve cardiovascular health, regardless of the type of the program adopted. Aerobic programs (combined and continuous aerobic exercises) seemed to have a more beneficial effect in reducing important cardiovascular risk markers.

Background: Kawasaki Disease (KD) is a generalized vasculitis in childhood with possible long-term impact on cardiovascular health besides the presence of coronary artery lesions. Standard vascular parameters such as carotid intima–media thickness (cIMT) have not been established as reliable markers of vascular anomalies after KD. The carotid intima–media roughness (cIMR) representing carotid intimal surface structure is considered a promising surrogate marker for predicting cardiovascular risk even beyond cIMT. We therefore measured cIMR in patients with a history of KD in comparison to healthy controls to investigate whether KD itself and/or KD key clinical aspects are associated with cIMR alterations in the long-term. Methods: We assessed cIMR in this case-control study (44 KD, mean age in years (SD); 13.4 (7.5); 36 controls, mean age 12.1 (5.3)) approximately matched by sex and age. Different clinical outcomes such as the coronary artery status and acute phase inflammation data were analyzed in association with cIMR values. Results: When comparing all patients with KD to healthy controls, we detected no significant difference in cIMR. None of the clinical parameters indicating the disease severity, such as the persistence of coronary artery aneurysm, were significantly associated with our cIMR values. However, according to our marginally significant findings (p = 0.044), we postulate that the end-diastolic cIMR may be rougher than the end-systolic values in KD patients. Conclusions: We detected no significant differences in cIMR between KD patients and controls that could confirm any evidence that KD predisposes patients to a subsequent general arteriopathy. Our results, however, need to be interpreted in the light of the low number of study participants.

Abstract
Background: Carotid intima-media thickness (cIMT) and stiffness (cS) are predictive markers of early vascular aging and atherosclerotic risk. This study assessed, whether exercise has protective effects on carotid structure and function or on vascular risk in the young. Methods: Volume and change of exercise (recreational and organized sports participation) of German adolescents and young adults was assessed within the prospective population-study KiGGS at KiGGS-Wave-1 (2009-2012) and KiGGS-Wave-2 (2014-2017) using standardized self-reporting questionnaires. CIMT and cS were measured by real-time B-mode ultrasound sequences with semi-automated edge-detection and automatic electrocardiogram-gated quality control in 2,893 participants (14-28 years, 49.6% female). A cumulative index for atherosclerotic risk (CV-R) included z-scores of mean arterial pressure, triglycerides, total/HDL-cholesterol-ratio, body mass index, and HbA1c. Results: At KiGGS-Wave-2 cross-sectional CV-R but not cS and cIMT was lower in all exercise-groups compared to "no exercise" (B = -0.73, 95%-CI = -1.26 to 0.19, p = 0.008). Longitudinal volume of exercise was negatively associated with CV-R (B = -0.37, 95%-CI = -0.74 to 0.00, p = 0.048) but not with cS and cIMT. Cross-sectional relative risk of elevated CV-R but not cS and cIMT was lower in all exercise-groups compared to "no exercise" (RR = 0.80, 95%-CI = 0.66 to 0.98, p = 0.033). High exercise volumes were associated with lower relative risk of elevated CV-R (RR = 0.80, 95%-CI = 0.65-0.97, p = 0.021) and cS in tendency but not with cIMT. Conclusions: Increased levels of exercise are associated with a better cardiovascular risk profile in young individuals, but not with cS and cIMT. Our study confirms previous recommendations on exercise in this age group without demonstrating a clear benefit on surrogate markers of vascular health.

Identifying Early Vascular Ageing in Patients With Metabolic Syndrome: Unresolved Issues and a Proposed Novel VAmets Score. Heart Lung Circ 2021; 30:1752-1761. [PMID: 34426074 DOI: 10.1016/j.hlc.2021.06.533] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 05/26/2021] [Accepted: 06/02/2021] [Indexed: 01/09/2023]
Abstract
PURPOSE To identify the features of early vascular ageing (EVA) in patients with metabolic syndrome (MetS), to assess the accuracy of existing methods for determining vascular age in MetS, and to derive a new score (VAmets) for the calculation of vascular age and predicting EVA in patients with MetS. METHODS Prospective open cohort study using routinely collected data from general practice. A total of 750 patients (age, 35-80 yrs old) with MetS were examined. EVA syndrome was detected in 484 patients with MetS and carotid-femoral pulse wave velocity (cfPWV) values exceeding average expected for age values by 2 or more standard deviations (SD). RESULTS The presence of type 2 diabetes and insulin resistance (IR) were associated with greater risk of EVA in MetS patients; the odds ratios were 2.75 (95% confidence interval [CI]: 2.34, 3.35) and 1.57 (95% CI: 1.16, 2.00), respectively. In addition, the risk of EVA increased by 76% with an increase in homeostatic model assessment ofinsulin resistance (HOMA-IR) by 1 unit, by 17% with an increase in high-sensitivity C-reactive protein (hs-CRP) by 1 mg/L, by 4% with an increase in diastolic blood pressure (DBP) by 1 mmHg, and by 1% with each (1) μmol/L increase in the level of uric acid (UA). The area under the curve (AUC) for predicting EVA in patients with MetS was 0.949 (95% CI: 0.936-0.963), 0.630 (95% CI: 0.589-0.671), 0.697 (95% CI: 0.659-0.736) and 0.686 (95% CI: 0.647-0.726), for vascular age calculated from carotid-femoral pulse wave velocity (cfPWV), Systematic COronary Risk Evaluation (SCORE) scale, QRESEARCH cardiovascular risk algorithm (QRISK-3) scale, and Framingham scale, respectively. Diabetes mellitus and clinical markers of IR (yes/no), HOMA-IR and UA level were used to develop a new VAmets score for EVA prediction providing a total accuracy of 0.830 (95% CI: 0.799-0.860). Based on the results of the study, a VAmets calculator was developed for diagnosing EVA in patients with MetS. (The calculator is available online at https://apps.medhub.pro/evams/) CONCLUSION: Carotid-femoral pulse wave velocity is at present the most widely studied index of arterial stiffness and fulfils most of the stringent criteria for a clinically useful biomarker of EVA in patients with MetS. There are parallel efforts for the effective identification and integration of a simple clinical score into clinical practice. Our score (VAmets) may accurately identify patients with MetS and EVA on the basis of widely available clinical variables and classic cardiovascular risk factors, and may assist in prioritising the calculation and use of vascular age in routine care.

Abstract
OBJECTIVE Attention deficit/hyperactivity disorder (ADHD) is associated with impairment in social, academic and job-related functioning in both children and adults. The purpose of this study is to investigate the susceptibility to cardiovascular risk factors in children with ADHD diagnosis through common carotid artery intima-media thickness (cIMT) measurement, to compare cIMT in ADHD and control groups and to evaluate the association between cIMT and ADHD symptom severity. METHODS The mean cIMT of 42 children with ADHD, ADHD symptom scales and a semi-structured psychiatric interview, and 42 age and sex matched healthy controls were measured with B-mode Doppler neck ultrasonography. RESULTS The median cIMT was significantly higher for the ADHD group compared to the healthy controls. There was a statistically significant, negative, moderate correlation between cIMT and Conners ADHD index score, hyperactivity score, oppositional score and the presence of ODD comorbidity. CONCLUSIONS In this study, we found significantly higher cIMT in children with ADHD when compared to healthy controls. Considering that increased cIMT is a sign of atherosclerosis and it can be used as a marker of cardiovascular risk factors, our finding may indicate that children with ADHD are at increased risk for cardiovascular diseases.KeypointscIMT was significantly higher in children with ADHD when compared to healthy controls.Higher cIMT in children with ADHD may indicate that children with ADHD are at increased risk for cardiovascular diseases.cIMT measurement may be studied as a potential tool for risk assessment before a child with ADHD is started on psychostimulant medications.

Management of High-Risk Atherosclerotic Patients by Statins May Be Supported by Logistic Model of Intima-Media Thickening. J Clin Med 2021; 10:jcm10132876. [PMID: 34209480 PMCID: PMC8267973 DOI: 10.3390/jcm10132876] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 06/20/2021] [Accepted: 06/23/2021] [Indexed: 11/16/2022] Open
Abstract
While the use of statins in treating patients with atherosclerosis is an undisputed success, the questions regarding an optimal starting time for treatment and its strength remain open. We proposed in our earlier paper published in Int. J. Mol. Sci. (2019, 20) that the growth of intima-media thickness of the carotid artery follows an S-shape (i.e., logistic) curve. In our subsequent paper in PLoS ONE (2020, 15), we incorporated this feature into a logistic control-theoretic model of atherosclerosis progression and showed that some combinations of patient age and intima-media thickness are better suited than others to start treatment. In this study, we perform a new and comprehensive calibration of our logistic model using a recent clinical database. This allows us to propose a procedure for inferring an optimal age to start statin treatment for a particular group of patients. We argue that a decrease in the slope of the IMT logistic growth curve, induced by statin treatment, is most efficient where the curve is at its steepest, whereby the efficiency means lowering the future IMT levels. Using the procedure on an aggregate group of severely sick men, 38 years of age is observed to correlate with the steepest point of the logistic curve, and, thus, it is the preferred time to start statin treatment. We believe that detecting the logistic curve’s steepest fragment and commencing statin administration on that fragment are courses of action that agree with clinician intuition and may support decision-making processes.

Abstract
AIM To evaluate the changes in CCA-IMT and vascular elasticity in healthy subjects in relation to age using radiofrequency data technology, to produce reference values for potential clinical applications. MATERIALS AND METHODS The following variables were measured in 160 subjects using radiofrequency data techniques: CCA-IMT, carotid distensibility (CD), local pulse-wave velocity (PWVβ), and stiffness (β). The subjects were divided into four age groups (30-39, 40-49, 50-59, and 60-69 years), with 20 men and 20 women in each group. The above parameters were compared among the different age groups. RESULTS CCA-IMT increased significantly with age (p<0.05). CD decreased significantly in the 40-49-years compared with the 30-39-years age group (p<0.05). PWVβ showed a significant increase in the 30-39-, 40-49-, and 50-59-years age groups (p<0.05). β increased significantly in the 50-59- compared with the 40-49-years age group (p<0.05). Compared with the 50-59-years age group, CD, PWVβ, and β showed no significant changes in the 60-69-years age group (p>0.05), with mean values of 329.39 ± 102.06 μm, 7.22 ± 1.91 m/s, and 10.04 ± 4.91, respectively. CONCLUSION Ultrasound radiofrequency data technology provides a non-invasive method for quantitatively and accurately assessing increased CCA-IMT and reduced vascular elasticity in healthy subjects in different age groups. The reference values produced in this study will be useful in clinical practice.

Abstract
Carotid intima-media thickness (cIMT) and carotid stiffness (CS) are important markers of atherosclerotic risk in the young. We assessed a novel third-generation method for its applicability in large population-based epidemiologic studies to determine strengths, limitations, completeness and predictors of unsuccessful measurement. Four thousand seven hundred ninety-eight 14- to 31-y-old participants of the German KiGGS cohort, which is based on a nationally representative sample with 11-y follow-up, underwent B-mode ultrasound examinations of the left and right common carotid artery with semi-automatic edge detection and automatic electrocardiogram-gated real-time quality control based on a sophisticated snake algorithm and subpixel interpolation. Overall completeness was 98% for far wall cIMT and 89% for CS parameters. Plane-specific completeness varied from 92%-96% for far wall and from 64%-69% for near-wall cIMT. Obesity independently predicted unsuccessful cIMT and CS measurements with odds ratios of 12.67 (95% confidence interval: 5.50-29.19) and 7.30 (4.87-10.94) compared with non-overweight after adjustment for blood pressure, cholesterol, smoking, hazardous drinking, age, sex and sonographer. Inter- and intra-rater reliabilities of cIMT and CS parameters in a sample of 15 young adults were good or excellent. Third-generation cIMT and CS measurements in the young with semi-automatic edge-detection and automatic real-time quality control has been successfully standardized with high reliability and very high completeness in a national survey setting. This provides a strong methodological foundation for further validation of the predictive value of cIMT and CS for atherosclerotic risk in the young.

Abstract
Aging is the main risk factor for vascular disease and ensuing cardiovascular and cerebrovascular events, the leading causes of death worldwide. In a progressively aging population, it is essential to develop early-life biomarkers that efficiently identify individuals who are at high risk of developing accelerated vascular damage, with the ultimate goal of improving primary prevention and reducing the health care and socioeconomic impact of age-related cardiovascular disease. Studies in experimental models and humans have identified 9 highly interconnected hallmark processes driving mammalian aging. However, strategies to extend health span and life span require understanding of interindividual differences in age-dependent functional decline, known as biological aging. This review summarizes the current knowledge on biological age biomarkers, factors influencing biological aging, and antiaging interventions, with a focus on vascular aspects of the aging process and its cardiovascular disease related manifestations.

Abstract
BACKGROUND AND AIMS Recent studies suggest that long-term endurance training may be damaging to the heart, thus increasing cardiovascular disease (CVD) risk. However, studies utilizing cardiac imaging are conflicting and lack measures of central and peripheral vascular structure and function, which are also independently predictive of CVD events. METHODS We performed a comprehensive assessment of cardiovascular structure and function in long-term (≥ 10 years) ultra-endurance athletes (ATH, 14 M/11 F, 50 ± 1 y) and physically active controls (CON, 9 M/9 F, 49 ± 2 y). RESULTS As expected, left ventricular mass and end-diastolic volume (echocardiography) were greater in ATH vs CON, whereas there was no difference in cardiac function at rest. Coronary artery calcium scores (computed tomography) were not statistically different between groups. There was no evidence of myocardial fibrosis (contrast magnetic resonance imaging) in any subject. Aortic stiffness (carotid-femoral pulse wave velocity) was lower in ATH vs CON (6.2 ± 0.2 vs 6.9 ± 0.2 m/s, p < 0.05), whereas carotid intima-media thickness (ultrasound) was not different between groups. Peripheral vascular endothelial function (flow-mediated vasodilation of the brachial artery) and microvascular function (peak blood velocity) in response to 5 min of forearm ischemia were not different between groups. Furthermore, there was no difference in 10-year coronary heart disease risk (ATH; 2.3 ± 0.5 vs CON; 1.6 ± 0.2%, p > 0.05). CONCLUSIONS Our data indicate that middle-aged ultra-endurance ATH do not have marked signs of widespread cardiovascular dysfunction or elevated CHD risk compared to CON meeting physical activity guidelines.

Abstract
AIM The association between serum uric acid (UA) and atherosclerosis in old people is controversial. Therefore, in this study, we clarified this association by assessing serum UA and common carotid atherosclerosis examined by carotid ultrasound in community-dwelling older people in their 70s, 80s and 90s in the SONIC study. METHODS A cross-sectional study was conducted involving 538 men and 577 women recruited from the community. The analysis was performed using serum UA as the explanatory variable and the maximum carotid intima-media thickness (max-CIMT) and mean-IMT as the dependent variables. The analysis was performed by multiple regression using traditional risk factors for atherosclerosis as adjustment variables. RESULTS Analysis of the association between serum UA and IMT revealed a significant correlation only in women >70 years old. Max-CIMT (β = 0.081, 95% CI = 0.026, 0.136; P = 0.004) and mean-IMT (β = 0.015, 95% CI = 0.003, 0.029; P = 0.016) were significant. In the analysis of each age group, a significant correlation was only found in women in their 70s for mean-IMT (β = 0.031, 95% CI = 0.008, 0.053; P = 0.008). CONCLUSION In community-dwelling women aged about 70 years old, elevated serum UA may be an independent risk factor for IMT thickening as a surrogate marker for atherosclerosis.

Abstract
Periodontal disease and arteriosclerotic disease are greatly affected by aging. In this study, the association of conventional risk factors and periodontal disease with atherosclerosis was longitudinally examined in Japanese older adults. Subjects in this study were 490 community-dwelling septuagenarians (69-71 years) randomly recruited from the Basic Resident Registry of urban or rural areas in Japan. At the baseline examination, all subjects underwent socioeconomic and medical interviews; medical examinations, including examinations for carotid atherosclerosis, hypertension, diabetes mellitus, and dyslipidemia; and conventional dental examinations, including a tooth count and measurement of probing pocket depth (PPD). After 3 years, 182 septuagenarians who had no atherosclerosis at the baseline examination were registered and received the same examination as at the baseline. In the re-examination conducted 3 years after the baseline survey, 131 (72.0%) of the 182 participants who had no atherosclerosis at the baseline examination were diagnosed with carotid atherosclerosis. Adjusting and analyzing the mutual relationships of the conventional risk factors for atherosclerosis by multiple logistic regression analysis for the 171 septuagenarians with a full set of data, the proportion of teeth with PPD ≥ 4 mm was independently related to the prevalence of atherosclerosis (odds ratio: 1.029, P < 0.022). This longitudinal study of Japanese older adults suggests that periodontal disease is associated with the onset/progression of atherosclerosis. Maintaining a healthy periodontal condition may be an important factor in preventing the development and progression of atherosclerosis.

Abstract
BACKGROUND AND AIMS There is a lack of studies simultaneously evaluating the impact of structural and functional atherosclerosis on cognition. We investigated the long-term predictive and interaction effects of structural and functional carotid atherosclerosis markers on future cognitive decline. METHODS Five hundred and twenty-eight middle-aged participants enrolled in the carotid atherosclerosis examination in Kaohsiung Atherosclerosis Longitudinal Study (KALS) between 2006 and 2009 were tested for cognition between 2016 and 2019. The Montreal Cognitive Assessment (MoCA) was used for the cognitive test. Baseline structural atherosclerosis was assessed by carotid intima-media thickness (cIMT) and plaque, whereas functional atherosclerosis was evaluated by carotid stiffness (β, Ep, and pulse wave velocity). Participants in the top quartile of cIMT and those with plaques were considered to have advanced structural atherosclerosis, whereas participants with all three stiffness parameters in the top quartile were defined to have advanced functional atherosclerosis. RESULTS The mean participant age at baseline was 53.88 ± 8.37 years. Each case of advanced structural atherosclerosis and advanced functional atherosclerosis was associated with low 10-year MoCA scores with p < 0.001 and p = 0.03, respectively. An interaction effect was observed between structural and functional atherosclerosis on the MoCA score 10 years later (p = 0.02). Participants with both advanced structural and functional markers showed a marked impact on future cognitive function, especially executive and language domains. CONCLUSION Carotid atherosclerosis in middle-aged individuals can predict their cognitive function in 10 years. Integrated information regarding both arterial wall and stiffness could help improve the predictive power for cognitive decline.

Abstract
Atherosclerosis, a chronic inflammatory disorder of the arterial wall, is a complex process whose dynamics are affected by multiple factors. The disease control consists of restraining it by administering statins. Slowing down or halting the plaque growth depends on the patient age at which the statin treatment begins and on the thickness of the intima-media (IMT) at that time. In this paper, we propose a mathematical model to estimate the sets of atherosclerosis states, from which the use of statins can restrain the disease. Our model is control-theoretic, and the estimated sets are the viability kernels, in the parlance of viability theory. To our best knowledge, this way of modelling the atherosclerosis progression is original. We compute two viability kernels, each for a different statin-treatment dose. Each kernel is composed of the vector [age, IMT] from which the disease can be restrained. By extension, the disease can’t be restrained from the kernel complements, this being mainly because of the disease and patient-age advancement. The kernels visualise tradeoffs between early and late treatments, which helps the clinician to decide when to start the statin treatment and which statin dose may be sufficient.

Abstract
Atherosclerosis is considered a chronic inflammatory disease of arteries associated with the aging process. Many risk factors have been identified and they are mainly related to life-styles, gene-environment interactions and socioeconomic status. Carotid and coronary artery diseases are the two major atherosclerotic conditions, being the primary cause of stroke and heart attack, respectively. Nevertheless, carotid plaque assumes particular aspects not only for the specific molecular mechanisms, but also for the types of atheroma which may be associated with a better or a worst prognosis. The identification of circulating blood biomarkers able to distinguish carotid plaque types (stable or vulnerable) is a crucial step for the improvement of adequate therapeutic approaches avoiding or delaying endarterectomy in the oldest old individuals (> 80 years), a population predicted to growth in the next years. The review highlights the most recent knowledge on carotid plaque molecular mechanisms, focusing on microRNAs (miRs), as a site-specific accelerated aging within the conceptual framework of Geroscience for new affordable therapies.

Prevalence of Subclinical Carotid Atherosclerosis and Role of Cardiovascular Risk Factors in Older Adults: Atherosclerosis and Aging are Not Synonyms. High Blood Press Cardiovasc Prev 2020; 27:231-238.

Abstract
INTRODUCTION Age is traditionally considered a major cardiovascular (CV) risk factor, but its real weight in the absence of other modifiable risk factors is not clear. AIM To compare the prevalence of subclinical carotid atherosclerosis, and its association with the main CV risk factors, between older adults and hypertensive adults. METHODS Cross-sectional study on 210 consecutive patients: 70 older adults (age ≥ 80 years), and 140 hypertensive adults having at least another CV risk factor. Patients had no history of peripheral artery disease or major CV events. RESULTS Mean age was 54.2 ± 7.2 years in hypertensive adults and 88.5 ± 5.5 years in older adults with a female prevalence in the latter group. Dyslipidemia and smoking were more prevalent in hypertensive adults, while chronic kidney disease was more prevalent in older adults. Prevalence of carotid plaques did not differ between hypertensive adults and older adults (48.2% vs 55.6%, respectively, p = 0.311). Age ≥ 80 years was not associated with a higher risk of carotid plaques even after adjusting for other risk factors (p = 0.204). Hypertension and dyslipidemia were the risk factors more strongly associated with carotid plaques in older adults and hypertensive adults, respectively. When older adults with hypertension were excluded from the analysis, prevalence of carotid plaques was significantly higher in hypertensive adults (p = 0.042). CONCLUSION Hypertension and dyslipidemia are the major determinant of atherosclerosis regardless of age in our study. Our findings support the concept that aging is not necessarily synonymous with atherosclerosis and highlight the key role played by superimposed CV risk factors on arterial ''bad aging''.

Abstract
Elevated serum uric acid (SUA) has been reported to be associated with an increased risk of cardiovascular diseases, but the role of SUA in intracranial atherosclerosis remains unclear. To investigate the association between SUA and intracranial atherosclerotic stenosis (ICAS), we evaluated 1522 subjects (305 with ICAS, 1217 without ICAS) with magnetic resonance angiography (MRA). Subjects were classified into ten groups according to the deciles of the SUA level. The rate of ICAS reached a minimum in the seventh decile (6.0-6.3 mg/dL; reference group). After adjusting for confounding factors, multivariate logistic regression analysis demonstrated that both low SUA level (≤ 3.8 mg/dL; OR, 2.34; 95% CI, 1.29-4.39; p = 0.006) and high SUA level (≥ 7.8 mg/dL; OR, 2.10; 95% CI, 1.15-3.92; p = 0.017) conferred greater risk for ICAS. In multivariable analysis with a quadratic model which used SUA as a continuous variable, a U-shaped association between SUA and the rate of ICAS was confirmed (α > 0; p < 0.001). The estimated SUA level associated with the lowest rate of ICAS was 6.2 mg/dL. In conclusion, our findings suggest a U-shaped association between ICAS and SUA.

Abstract
BACKGROUND To investigate the link between carbamylated low-density lipoprotein (ca-LDL), atherogenic index of plasma (AIP), atherogenic coefficient (AC), Castelli's risk indices I and II (CRI I and II) and subclinic atherosclerosis in psoriatic arthritis (PsA). METHODS Thirty-ninepatients and 19 age, sex, body mass index matched healthy controls were included. Insulin resistance (IR) was assessed with homeostasis of model assessment-IR (HOMA-IR). Carotid intima-media thickness (CIMT) was measured at both common carotid arteries and mean CIMT was calculated. RESULTS The mean age was 49.50 ± 11.86 years and 64.1% were females in PsA group. In the PsA group, CIMT and HOMA-IR were significantly higher (p = 0.003, p = 0.043, respectively). AIP, AC, TG/HDL, CRI-1, CRI-2 and ca-LDL levels were similar between groups. In PsA group, CIMT was positively correlated with HOMA-IR, TG/HDL and AIP. Although ca-LDL was positively correlated with serum amyloid A (r = 0.744, p < 0.001), no correlation was detected between ca-LDL and CIMT (r = 0.215, p = 0.195). PsA patients with IR tended to have higher ca-LDL levels than patients without IR, but this difference lacked statistical significance (33.65 ± 26.94, 28.63 ± 28.06, respectively, p = 0.237). CONCLUSIONS A significant increase in CIMT was seen in PsA patients without clinically evident cardiovascular disease or any traditional atherosclerosis risk factors. CIMT was correlated with HOMA-IR, TG/HDL and AIP.

Abstract
Objective. The purpose of this prospective study was to ascertain if lipid profile parameters could serve as predictors of carotid intima-media thickness (CIMT), which, when combined, may improve the sensitivity of sonographic CIMT measurement in the diagnosis of subclinical atherosclerotic changes. Methods. The lipid profiles and CIMT of 181 subjects without cardiovascular risk factors were measured at the internal, external, common, and bulbar segments. Results. The mean CIMT values obtained were 0.620 ± 0.055 cm for men and 0.575 ± 0.051 cm for women, and the η2 values (η2 < 0.04) were used as a measure of association. Across all segments of both carotid arteries, lipid profiles were significantly and moderately associated with but not predictive of CIMT (fasting blood sugar, total cholesterol, and low-density lipoprotein: η2 = 0.99–0.24). Conclusions. Although lipid profiles were moderately associated with CIMT, they are not significant predictors; hence, combining them with CIMT does not improve the diagnostic sensitivity of sonography in atherosclerosis screening.

Correlation between carotid intima-media roughness and cardiovascular risk factors. Exp Ther Med 2019; 18:49-56.

Abstract
Arterial intima-media roughness (IMR) may indicate an early manifestation of atherosclerosis. To date, few studies have been performed to quantitatively evaluate carotid IMR by ultrasonography (US). The aim of the present study was to analyze the effect of cardiovascular risk factors on carotid IMR. A total of 185 subjects were enrolled for US examination of carotid arteries. Carotid intima-media thickness (IMT) and IMR were measured in US images by a novel automatic software. According to the number of combined high-risk factors for coronary heart disease, subjects were assigned to four groups (risk groups 0, 1, 2 and 3+). IMR was lowest in risk group 0 (32.9±2.7 µm), higher in risk group 1 (64.5±6.9 µm; P<0.01 vs. risk group 0) and highest in risk groups 2 and 3+ (89.1±7.4 and 92.0±6.7 µm, respectively; P<0.01 vs. risk groups 0 and 1). According to a multivariate regression analysis, age, systolic blood pressure, smoking status and the triglyceride/high-density lipoprotein cholesterol ratio were significant predictors of IMR. There was a progressive increase in carotid artery plaque with increasing tertiles of IMR (4.9, 33.9 and 53.2% in tertiles 1, 2 and 3, respectively; P<0.05). Compared with that of subjects in the lowest tertile of IMR, those in the highest tertile had a significantly elevated risk of the presence of plaque in the carotid tree (odds ratio=10.61, 95%CI: 2.15–52.49, P=0.004). Quantification of carotid IMR from US images with this software is feasible, and carotid IMR, which may help estimate the extent of atherosclerosis, may be used as a complementary factor to stratify patients with cardiovascular risk factors.

Abstract
OBJECTIVES To investigate carotid intima-media roughness (IMR) in hypertensive patients with normal carotid intima-media thickness (IMT) using automatic identification software and the correlation between carotid IMR and risk factors. METHODS This case-control study comprised 61 hypertensive patients with normal carotid IMT and 51 control participants. Carotid IMR, carotid IMT, pulsed wave velocity (PWV), stiffness (β), and arterial compliance were determined by carotid ultrasound and image postprocessing using an automatic identification program and echo-tracking analysis software. RESULTS Carotid IMR, mean carotid IMT, maximum carotid IMT, β, and PWV in the hypertension group were higher than those in the control group (58.24 versus 34.61 μm, 641.17 versus 576.48 μm, 746.82 versus 640.55 μm, 9.42 versus 7.35, and 7.10 versus 5.86 m/s, respectively; P < .05), and arterial compliance was lower than that in the control group (0.70 versus 0.95 mm2 /kPa; P < .05). Intima-media roughness was correlated with maximum IMT, mean IMT, PWV, β, age, diagnosis of hypertension for greater than 1 year, and pulse pressure. Multivariate logistic regression showed that age, diagnosis of hypertension for greater than 1 year, and pulse pressure were influential factors for IMR in hypertensive patients, with odds ratios of 6.719 (95% confidence interval, 1.658-27.221; P = .008), 4.726 (95% confidence interval, 1.174-19.022; P = .029), and 3.998 (95% confidence interval, 1.033-15.466; P = .045), respectively. CONCLUSIONS Carotid IMR and the elasticity index have important clinical importance in evaluating the risk of early atherosclerosis in hypertensive populations.

Abstract
Cardiovascular disease (CVD) is a major threat to human health since it is the leading cause of death in western countries. Atherosclerosis is a type of CVD related to hypertension, diabetes, high levels of cholesterol, smoking, oxidative stress, and age. Atherosclerosis primarily occurs in medium and large arteries, such as coronary and the carotid artery and, in particular, at bifurcations and curvatures. Atherosclerosis is compared to an inflammatory disease where a thick, porous material comprising cholesterol fat, saturated sterols, proteins, fatty acids, calcium etc., is covered by an endothelial membrane and a fragile fibrous tissue which makes atheromatic plaque prone to rupture that could lead to the blockage of the artery due to the released plaque material. Despite the great progress achieved, the nature of the disease is not fully understood. This paper reviews the current state of modelling of all levels of atherosclerosis formation and progress and discusses further challenges in atherosclerosis modelling. The objective is to pave a way towards more precise computational tools to predict and eventually reengineer the fate of atherosclerosis.

Abstract
We propose a control-theoretic aggregate model of the progression of atherosclerosis plaque, a chronic inflammatory disease of the arterial wall, to study the basic features of this disease. In the model, we exploit the role of inflammation in the disease progression, and use statins-drugs commonly recommended in atherosclerosis-to control this progression. We use a logistic function to allow for constrained growth of plaque. In the model, both the patient's age and overall health impact the plaque growth and its sensitivity to statins. The model parameters are estimated using original data, or calibrated using published research as well as our own clinical and laboratory studies. We contend that our model helps to gauge the statins' impact on a patient's plaque thickness, hence the disease's progression and cardiovascular risk, without requiring artery scans.

Abstract
Medical Doppler ultrasound is usually utilized in the clinical adjusting to evaluate and estimate blood flow in both the major (large) and the minor (tiny) vessels of the body. The normal and abnormal sign waveforms can be shown by spectral Doppler technique. The sign waveform is individual to each vessel. Thus, it is significant for the operator and the clinicians to understand the normal and abnormal diagnostic in a spectral Doppler show. The aim of this review is to explain the physical principles behind the medical Doppler ultrasound, also, to use some of the mathematical formulas utilized in the medical Doppler ultrasound examination. Furthermore, we discussed the color and spectral flow model of Doppler ultrasound. Finally, we explained spectral Doppler sign waveforms to show both the normal and abnormal signs waveforms that are individual to the common carotid artery, because these signs are important for both the radiologist and sonographer to perceive both the normal and abnormal in a spectral Doppler show.

Abstract
Objectives To analyze the correlation between the serum concentration of interleukin- (IL-) 23 and atherosclerotic changes, traditional atherosclerotic risk factors, the autoantibody profile, and involvement of selected organs in systemic lupus erythematosus (SLE) patients. Patients and Methods We studied 94 SLE patients and 27 controls. We analyzed the IL-23 serum concentration, autoantibodies, carotid intima-media thickness and atherosclerotic plaque, the ankle-brachial index, atherosclerotic risk factors, and organ manifestations. Results Concentrations of IL-23 significantly differed between SLE patients and the controls (p = 0.0015). On the basis of multivariate stepwise analysis, we revealed that high levels of IL-23 were associated with atherosclerotic plaque in common femoral arteries (OR = 12.67; 95% CI: 1.41-113.84), lupus nephritis (OR = 3.69; 95% CI: 1.16-12.22), and obesity (OR = 4.21; 95% CI: 1.40-12.67). Autoantibodies related to IL-23 were anti-phosphatidylethanolamine antibodies (OR = 11.06; 95% CI: 1.24-98.65) and anti-SS-B/La antibodies (OR = 15.43; 95% CI: 1.73-137.25). Conclusions IL-23 may be involved in lupus nephritis pathogenesis. Through its association with obesity and selected antiphospholipid antibodies, IL-23 might promote a hypercoagulable state contributing to atherothrombosis development in SLE patients.

Abstract
OBJECTIVES The presence of atherosclerotic plaque in the carotid arteries is a strong predictor of cardiovascular disease (CVD). Research and data on CVD risk have been derived primarily from individuals aged 55 years or older, and assessment of CVD risk among young and middle-aged adults seldom has been studied. The use of ultrasonography to measure carotid intima-media thickness (IMT) and carotid plaque appears to have utility to detect subclinical atherosclerosis in asymptomatic adults. This study evaluated the presence of carotid plaque using ultrasonography among healthy young and middle-aged adults. METHODS Participants were men and women recruited in Miami, Florida, and were 18 to 50 years old with no history of CVD. Participants underwent a general physical examination and carotid artery ultrasonography to evaluate carotid IMT and carotid plaque. RESULTS From a total of 173 participants with a mean age of 34 years (standard deviation 8.9), 21.0% (95% confidence interval [CI] 15.0-27.2) were identified as having carotid plaque. IMT values ranged from 0.49 to 1.03 mm, with a mean value of 0.70 mm (standard deviation 0.09). In multivariable logistic regression older age (adjusted odds ratio [AOR] 1.08, 95% CI 1.01-1.16, P = 0.024) and cigarette smoking (AOR 2.67, 95% CI 1.02-7.00, P = 0.045) were associated with plaque, after controlling for IMT (AOR 2.55, 95% CI 1.40-4.65, P = 0.002). CONCLUSIONS Traditional CVD risk factors such as those evaluated in this study may fail to provide adequate predictive value of carotid atherosclerosis in younger populations with no history of CVD, because the majority of traditional risk factors identified in previous research were not associated with carotid plaque in this young sample. Further research assessing nontraditional risk factors among asymptomatic individuals is required, and the evaluation of IMT as an intervention tool to detect CVD risk in these asymptomatic populations is warranted.
