Carotid intima–media thickness (IMT), plaque, and stenosis are widely used as early surrogate markers of subclinical atherosclerosis and strong predictors of future deaths and cardiovascular events. Albuminuria is an indicator of generalized endothelial dysfunction that speeds up atherosclerosis. However, previous studies reporting these associations cannot rule out the confounding effect of albuminuria. We aimed to examine the independent and joint relationships between IMT markers and 10-year mortality in community-dwelling Taiwanese adults. This work was a community-based prospective cohort study consisting of 2956 adults aged at least 30 years recruited in 2007 and followed up through 2019. Cox proportional hazard regression models were used to examine associations of these subclinical atherosclerosis markers with mortality. During an average of 9.41 years of follow up, 242 deaths occurred. The mortality rate was 8.70 per 1000 person-years. Compared with those with carotid IMT less than 1.0 mm, persons with severely increased carotid IMT (≥2.0 mm) had an increased risk for death (hazard ratio (HR): 1.79; 95% confidence interval (CI): 1.07, 3.00). Compared with those without carotid plaque, persons with carotid plaque were more likely to have an increased risk for death (1.65; 1.21–2.32). Compared with those with carotid stenosis less than 25%, persons with carotid stenosis of 25–36% had a significant increased risk for death (1.57; 1.12–2.22). Considering these three IMT markers along with the traditional risk factors (c-statistic: 0.85) significantly increased their predictive ability of mortality compared with any individual variable’s predictive ability (all p-values < 0.001 for comparisons of c-statistic values). Carotid IMT measures, including IMT thickness, carotid plaque, and carotid stenosis were significant independent predictors of mortality. Our study supports evidence of blood pressure-related media thickening markers to assess future mortality risks in Chinese adults of general population.

Patients with familial hypercholesterolemia (FH) are at increased risk of premature cardiovascular disease. We compared factors associated with the presence of carotid plaques and carotid intima–media thickness (cIMT), markers of subclinical atherosclerosis, in 241 patients with FH (98, 40.7% men; mean age 41 ± 18.4 years). Patients with FH having carotid plaques (36.5%) had mean age, apolipoprotein (apo) B, glucose, apoA1, systolic blood pressure (SBP) and diastolic BP, waist/hip ratio (WHR), and body mass index higher than patients without plaques. Logistic regression revealed that apoB (odds ratio [OR] per 1 unit change 1.03, P = .005), high-density lipoprotein cholesterol (HDL-C; OR per 1 standard deviation [SD] change 0.59, P = .015), and non-HDL-C (OR per 1SD change 1.53, P = .04) were significantly associated with the presence of plaques. The cIMT correlated with obesity parameters, BP, apoB, glucose, high-sensitivity C-reactive protein, creatinine, γ-glutamyl transpeptidase, and alanine transaminase ( P < .001). Regression analysis revealed that cIMT was significantly associated with apoB, SBP, and WHR. These results confirm the role of apoB-containing lipoproteins and low HDL-C with the presence of carotid plaques and apoB, BP, and WHR with cIMT.

Introduction The Receptor for Advanced Glycation End-products (RAGE) is a multi-ligand receptor that propagates vascular cell dysfunction leading to proinflammatory disease states. RAGE is produced as a membrane bound and soluble isoform (soluble RAGE (sRAGE)), with the soluble isoform demonstrated to act as a RAGE decoy preventing cellular activation and atherosclerosis. Recent cohort studies have suggested that serum levels of sRAGE are associated with the risk of CVD and therefore may be a novel biomarker for cardiovascular disease states. Hypothesis We hypothesized that sRAGE levels are associated with subclinical atherosclerosis in an ethnically diverse population. Methods We included 1,102 stroke-free participants from the multi-ethnic Northern Manhattan Study (NOMAS) who underwent high-resolution carotid B-mode ultrasound to measure carotid plaque phenotypes (density, thickness, and area) and carotid intima-media thickness (IMT). Plaque density was characterized by Gray Scale Median (GSM). Serum sRAGE was measured by ELISA and log-transformed to stabilize variance. Multiple linear and logistic regressions were employed to estimate sRAGE associations with IMT and plaque measures. Results The mean age at time of ultrasound was 70.7±8.6yrs; 65% were Hispanic, 19% black, and 16% white. The majority of subjects had carotid plaque present (54%) with the median GSM 38(0-190). Mean plaque thickness (IQR) was 1.30(0-3.99)mm and mean area (IQR) 2.43(0-96.75)mm2. Mean IMT was 0.93±0.09mm. High sRAGE levels were associated with more echolucent plaques (OR 1.2, 95% CI 1.03-1.42), especially among Hispanics (OR 1.26, 95% CI 1.04-1.54). These relationships remained after adjusting for sociodemographic and vascular risk factors. No association was seen between sRAGE levels and carotid IMT, plaque thickness or area. Conclusion In the present study, higher sRAGE levels were associated with echolucent (lower density) plaque, especially among Hispanic subjects. Our data suggest sRAGE levels may be associated with atherosclerotic plaque morphology and its vulnerability, especially among minority groups. These findings further support RAGE as a novel target for anti-atherosclerosis interventions.

Background: Controversies concerning the association between insulin therapy and atherosclerotic lesions in type 2 diabetes mellitus (T2DM) remain to exist. The purpose of this study was to investigate whether insulin therapy in T2DM patients is linked with the increased risk of carotid atherosclerosis in real-world settings.Methods: We retrospectively enrolled 2,356 hospitalized patients with T2DM, including 1,716 subjects receiving insulin therapy and 640 subjects without receiving insulin therapy. Carotid atherosclerotic lesions including carotid intima-media thickness (CIMT), carotid plaque and carotid stenosis were assessed by Doppler ultrasonography and were compared between T2DM patients treated with and without insulin.Results: After adjusting for age and duration of diabetes, there was a significant increase in the prevalence of carotid plaque in both men (52.0 vs. 41.7%, p = 0.007) and women (49.6 vs. 39.7%, p = 0.003) receiving insulin therapy than in those without receiving insulin therapy. After further controlling for other confounding factors, compared with the patients without receiving insulin therapy, the risk of carotid plaque was still significantly increased not only in women treated with insulin (OR: 1.810; 95% CI: 1.155–2.837, p = 0.010), but also in men treated with insulin (OR: 1.867; 95% CI: 1.307–2.666; p = 0.001). Additionally, HOMA2-B% was higher in both women and men without receiving insulin therapy compared with those receiving insulin therapy (p &lt; 0.001 in both men and women), but HOMA-IR was significantly higher in patients treated with insulin than in those without receiving insulin therapy (p &lt; 0.001 in both men and women).Conclusions: Insulin therapy is associated with markedly increased risk of carotid atherosclerotic lesions in type 2 diabetes, which partly attribute to the more serious insulin resistance in T2DM patients receiving insulin therapy.

Background Increased oxidative stress, leukocyte telomere length (LTL) shortening, endothelial dysfunction, and lower insulin-like growth factor (IGF)-1 concentrations reflect key molecular mechanisms of aging. We hypothesized that biomarkers representing these pathways are associated with measures of subclinical atherosclerosis and all-cause mortality. Methods and results We evaluated up to 2,314 Framingham Offspring Study participants (mean age 61 years, 55% women) with available biomarkers of aging: LTL, circulating concentrations of IGF-1, asymmetrical dimethylarginine (ADMA), and urinary F2-Isoprostanes indexed to urinary creatinine. We evaluated the association of each biomarker with coronary artery calcium [ln (CAC+1)] and carotid intima-media thickness (IMT). In multivariable-adjusted linear regression models, higher ADMA levels were associated with higher CAC values (βADMA per 1-SD increase 0.25; 95% confidence interval [CI] [0.11, 0.39]). Additionally, shorter LTL and lower IGF-1 values were associated with higher IMT values (βLTL −0.08, 95%CI −0.14, −0.02, and βIGF-1 −0.04, 95%CI −0.08, −0.01, respectively). During a median follow-up of 15.5 years, 593 subjects died. In multivariable-adjusted Cox regression models, LTL and IGF-1 values were inversely associated with all-cause mortality (hazard ratios [HR] per SD increase in biomarker, 0.85, 95% CI 0.74–0.99, and 0.90, 95% CI 0.82–0.98 for LTL and IGF-1, respectively). F2-Isoprostanes and ADMA values were positively associated with all-cause mortality (HR per SD increase in biomarker, 1.15, 95% CI, 1.10–1.22, and 1.10, 95% CI, 1.02–1.20, respectively). Conclusion In our prospective community-based study, aging-related biomarkers were associated with measures of subclinical atherosclerosis cross-sectionally and with all-cause mortality prospectively, supporting the concept that these biomarkers may reflect the aging process in community-dwelling adults.

Abstract Background Renal function is a key factor of cardiovascular disease. Carotid intima-media thickness (IMT) has been widely used as a marker of early subclinical atherosclerosis. The determinants of cystatin C, a novel marker of renal function, have not been extensively studied in the Asian population. This study aimed to assess the determinants of cystatin C and explore whether carotid thickening was associated with urinary albumin-creatinine ratio and cystatin C in community-living Taiwanese adults. Methods A cross-sectional study was conducted on participants from Taichung City, Taiwan. All the participants underwent carotid ultrasonography. Carotid IMT-mean and IMT-maximum were derived. Kidney biomarkers were measured on the basis of urinary albumin-to-creatinine ratio (ACR) and cystatin C. Multiple linear regression analysis was used. Results A total of 1032 individuals were recruited, and 469 (45.44%) of them were men. An increased cystatin C level was significantly associated with older age, male gender, lack of physical activity, low HDL cholesterol, abdominal obesity, high hs-CRP, and high ACR. The multivariate-adjusted mean carotid IMT-mean and IMT-maximum values significantly increased by 80.49 and 195.23 μm for every one unit of increase in cystatin C level and by 0.07 and 0.14 μm for every one unit of increase in ACR, respectively (all p < 0.001 except ACR on IMT-maximum with p < 0.01). Lack of physical activity, low HDL, abdominal obesity, high hs-CRP, and high ACR were the determinants of cystatin C. Conclusion Cystatin C and ACR were strongly and linearly associated with carotid thickening, a marker of subclinical atherosclerosis.

Introduction: Restless legs syndrome (RLS) is a common chronic disorder characterized by an irresistible need to move the lower limbs that is usually worse in the evening and is associated with sleep disturbances. RLS has been associated with hypertension and has been proposed as a marker for increased cardiovascular risk. Hypothesis: Individuals with RLS have an increased common carotid intima-media thickness (cIMT) relative to individuals without RLS. Methods: We evaluated cross-sectional relation of RLS and cIMT in 1,147 disease-free Mexican women of the Mexican Teachers’ Cohort. In 2011, participants responded to a follow-up questionnaire that included standardized questions addressing the four minimal diagnostic criteria of the International Restless Legs Study Group. Participants were asked: “Do you have unpleasant leg sensations (like crawling, loss of sensation or pain) combined with restlessness and an urge to move your legs?”, “Do these symptoms occur only at rest?”, “Does moving improve these symptoms?”, “Are these symptoms worse in the evening or at night compared with the morning?” Women who answered yes to all the four questions were defined as having RLS. Between 2012 and 2013, a subsample of participants were invited for a clinical visit where neurologists assessed cIMT with an ultrasound. cIMT measurements were found to be reproducible in a substudy in 52 participants (intra-class correlation=0.89). We defined subclinical atherosclerosis as a cIMT ≥0.8 mm or the presence of plaque. Results: Among women with a mean age of 48.2 (SD±4.3), the prevalence of RLS was 14.2% (cases, 163). The age-adjusted mean difference of cIMT comparing participants with RLS to those without RLS was 0.009mm (95%CI -0.004 to 0.023). After further adjustment for diabetes, hypercholesterolemia, migraine, oral contraceptive use, menopause, smoking, body mass index, physical activity and alcohol, the mean difference of cIMT comparing participants with and without RLS was not statistically different (0.007mm; 95%CI -0.007 to 0.021). The prevalence of subclinical atherosclerosis was 27% (n=44) in those with RLS and 21.9% (n=215) in those without RLS. The age-adjusted OR comparing women with RLS to those without RLS was 1.23 (95%CI 0.83-1.82). In the multivariable model the OR remained non-significant (1.16, 95%CI 0.77-1.74). Conclusions: In this cross-sectional study in middle-aged women, RLS was not associated to cIMT. Our results do not support the observation that individuals with RLS are at an increased risk for cardiovascular disease.

ObjectivesComorbid hypertension and hyperhomocysteinemia is an important risk factor for carotid atherosclerotic plaque formation. We put forward the hypothesis that the subjects with comorbid prehypertension and hyperhomocysteinemia also had an increased risk of subclinical atherosclerosis, using carotid intima–media thickness (CIMT) as the marker of the atherosclerotic process.MethodsA total of 4102 asymptomatic Chinese subjects aged 18–60 years were divided into four groups according to blood pressure (BP) and homocysteine (HCY) level: the control group without prehypertension or hyperhomocysteinemia, isolated prehypertension group, simple hyperhomocysteinemia group and prehypertension with hyperhomocysteinemia group. Serum lipids, fasting blood glucose (FBG), HCY and CIMT were measured.ResultsThere was significant difference in the positive rates of increased CIMT among four groups. Compared with the controls, the subjects in the other three groups had a higher risk of increased CIMT (isolated prehypertension group, OR 2.049, 95% CI 1.525 to 2.754; simple hyperhomocysteinemia group, OR 2.145, 95% CI 1.472 to 3.125; prehypertension and hyperhomocysteinemia group, OR 3.199, 95% CI 2.362 to 4.332). However, by multiple logistic regression analysis, only comorbid prehypertension and hyperhomocysteinemia was independently associated with increased CIMT (OR 1.485, 95% CI 1.047 to 2.108, P<0.05).ConclusionsComorbid prehypertension and hyperhomocysteinemia was an independent risk factor of subclinical atherosclerosis in asymptomatic Chinese, but isolated prehypertension or hyperhomocysteinemia was not. Therefore, combined intervention for prehypertension and hyperhomocysteinemia may contribute to decrease the incident of cardiovascular disease.

Abstract Introduction Traditional risk assessment tools classify the majority of women at low risk despite cardiovascular disease remaining the leading cause of death in women. Additionally conventional stress testing techniques have poor predictive value in women, due to unique pathophysiological mechanisms causing ischaemia in women, and the lower prevalence of obstructive CAD. The study sought to evaluate the role of adjuvant carotid ultrasound (CU) in women attending for stress echocardiography (SE). Methods and results 415 women (Mean age 62±10 years, 28% Diabetes Mellitus, Mean BMI 28) attending for SE prospectively underwent CU, to assess Carotid Intima-media thickness (CIMT) and the presence of plaque. 47 women (11%) had inducible wall motion abnormalities, and carotid disease (CD) was present in 46% (Carotid plaque in 41%, 15% CIMT >75th percentile). Women with CD were older (65 vs 58 years, p<0.0001), more likely to have Diabetes (41% vs 21%, p=0.0001) and hypertension (67% vs 36%, p<0.01), and had higher pretest probability of CAD (59% vs 41%, p<0.0001). 40% of women classified as low Framingham, were found to have evidence of CD. Conversely, only 40% of women classified as high Framingham risk, had CD. The positive predictive value of SE for flow-limiting CAD was 51%, but the presence of carotid plaque improved this to 71% (p<0.01). Of all clinical and test parameters, carotid plaque (p=0.001) and SE result (p=0.01) were the only independent predictors of >70% angiographic. Conclusion CU significantly improves the accuracy of SE alone for identifying flow-limiting disease on coronary angiography. Non-invasive assessment of subclinical atherosclerosis using CU offers an individualized disease-guided approach in women, where conventional scoring systems offer modest risk stratification.

Microalbuminuria is closely associated with the risk of cardiovascular disease and all-cause mortality in the general population. Less is known about its relationship with subclinical atherosclerosis. We aimed to assess the prevalence of microalbuminuria and its relationship with subclinical atherosclerosis in middle-aged, nondiabetic, apparently healthy individuals (N = 187; 40.1% men, 59.9% women; aged 35–55 years) as well as to evaluate its potential associations with established risk modifiers, especially with the presence of carotid plaque. Clinical and laboratory parameters, the estimated 10-year fatal cardiovascular risk (SCORE), as well as circulating, functional (flow mediated vasodilation, ankle-brachial index, augmentation index, and pulse wave velocity), and morphological markers (mean carotid intima–media thickness, and carotid plaque) of subclinical atherosclerosis were analysed in group with vs. without microalbuminuria. Microalbuminuria was present in 3.8% of individuals with SCORE risk 0.43 ± 0.79%. Functional markers predominated in both groups. Carotid intima–media thickness (mean ± SD) in both groups was in range: 0.5–0.55 ± 0.09–0.14 mm. Carotid plaque was more frequent in group with (14.3%) vs. without (4.4%) microalbuminuria. Microalbuminuria had no statistically significant effect on most markers of subclinical atherosclerosis, but the increasing value of microalbuminuria was significantly associated with the occurrence of carotid plaque (p = 0.035; OR = 1.035; 95% CI = 1.002–1.07). Additional multiple logistic regression analysis, where variables belonged to microalbuminuria, number of risk factors, and family history, finally showed only two variables: microalbuminuria (p = 0.034; OR = 1.04; 95%CI = 1.003–1.09) and the number of risk factors (p = 0.006; OR = 2.15; 95% CI = 1.24–3.73) with independent and significant impact on the occurrence of carotid plaque. Our results may indicate an association of microalbuminuria with the presence of carotid atherosclerotic plaque; in addition, microalbuminuria and the number of risk factors appear to be possible predictors of the carotid plaque occurrence. Monitoring microalbuminuria may improve the personalized cardiovascular risk assessment in nondiabetic, low-to-moderate cardiovascular risk individuals with or without hypertension.
