Project description:Carotid intima-media thickness has been reported to predict kidney function decline. However, whether carotid intima-media thickness is associated with a hard kidney end point, ESRD, has not been investigated.We studied 13,197 Atherosclerosis Risk in Communities participants at visit 1 (1987-1989) without history of cardiovascular disease, including coronary heart disease, stroke, and heart failure, at baseline and assessed whether carotid intima-media thickness measured by B-mode ultrasound is associated with ESRD risk using Cox proportional hazards models. Regarding carotid intima-media thickness parameters, we investigated the mean and maximum values of overall and segment-specific (common, bifurcation, and internal carotid arteries) measurements.Mean age was 54.0 (SD=5.7) years old, and there were 3373 (25.6%) blacks and 7370 (55.8%) women. During a median follow-up of 22.7 years, 433 participants developed ESRD (1.4/1000 person-years). After adjusting for shared risk factors for atherosclerosis and kidney disease, including baseline kidney function, carotid intima-media thickness was significantly associated with ESRD risk (hazard ratio [HR] between quartiles 4 and 1, 1.46; 95% confidence interval [95% CI], 1.02 to 2.08 for overall mean intima-media thickness and HR between quartiles 4 and 1, 1.75; 95% CI, 1.24 to 2.48 for overall maximum intima-media thickness). The associations were largely consistent in demographic and clinical subgroups. When we explored segment-specific intima-media thicknesses, the associations with ESRD were most robust for bifurcation carotid (e.g., adjusted HR between quartiles 4 and 1 of mean intima-media thickness, 1.49; 95% CI, 1.04 to 2.13 for bifurcation; adjusted HR between quartiles 4 and 1 of mean intima-media thickness, 1.36; 95% CI, 0.94 to 1.97 for common; and adjusted HR between quartiles 4 and 1 of mean intima-media thickness, 0.93; 95% CI, 0.67 to 1.29 for internal).Carotid intima-media thickness was independently associated with incident ESRD in the general population, suggesting the shared etiology of atherosclerosis and ESRD.

Project description:IntroductionStudies on the association between atherosclerosis and long-term exposure to ambient air pollution suggest that carotid intima-media thickness (CIMT), a marker of subclinical atherosclerosis, is positively associated with particulate matter (PM) exposure. However, there is heterogeneity between the different studies concerning the magnitude of this association. We performed a meta-analysis to determine the strength of the association between CIMT and particulate air pollution.MethodsWe queried PubMed citation database and Web of Knowledge up to March 2015 in order to identify studies on CIMT and particulate air pollution. Two investigators selected and computerized all relevant information, independently. Eight of the reviewed epidemiological publications provided sufficient details and met our inclusion criteria. Descriptive and quantitative information was extracted from each selected study. The meta-analysis included 18,349 participants from eight cohorts for the cross-sectional association between CIMT and PM and 7,268 participants from three cohorts for the longitudinal analysis on CIMT progression and PM exposure.ResultsThe average exposure to PM2.5 in the different study populations ranged from 4.1 to 20.8 µg/m3 and CIMT averaged (SD) 0.73 (0.14) mm. We computed a pooled estimate from a random-effects model. In the combined cross-sectional studies, an increase of 5 µg/m3 PM2.5 was associated with a 1.66% (95% CI: 0.86 to 2.46; P<0.0001) thicker CIMT, which corresponds to an average increase of 12.1 µm. None of the studies moved the combined estimate outside the confidence interval of the overall estimate. A funnel plot suggested absence of publication bias. The combined longitudinal estimate showed for each 5 µg/m3 higher PM2.5 exposure, a 1.04 µm per year (95% CI: 0.01 to 2.07; P=0.048) greater CIMT progression.ConclusionOur meta-analysis supports the evidence of a positive association between CIMT, a marker of subclinical atherosclerosis, and long-term exposure to particulate air pollution.

Project description:Background: The relationship of cardiorespiratory fitness (CRF) with subclinical atherosclerosis affected by the body adiposity has been observed in children, whereas this relationship remains unclear in young adults. Methods and Results: A total of 1520 military recruits, aged 18-40 years, were included in Taiwan in 2018-2020. All subjects underwent detailed physical and blood laboratory examinations. CRF was evaluated by time for a 3000 m run, and subclinical atherosclerosis was evaluated by intima-media thickness of the bulb of the left common carotid artery (cIMT) utilizing high-resolution ultrasonography. Multivariable linear regression analysis with adjustments for age, sex, cigarette smoking, alcohol intake, systolic and diastolic blood pressure, high- and low-density lipoprotein cholesterols, fasting glucose, waist circumference, serum uric acid and serum triglycerides were utilized to determine the correlation between CRF and cIMT. CRF was independently correlated with cIMT (standardized β: 0.11, p < 0.001). Of the cardiometabolic risk markers, serum triglycerides were the only independent risk marker of cIMT (standardized β: 0.063, p = 0.03). In addition, the association of CRF with cIMT did not differ between those with a body mass index (BMI) ≥ 25 kg/m2 and those with BMI < 25 kg/m2 (standardized β: 0.103 and 0.117; p = 0.01 and 0.005, respectively). Conclusions: In physically active young men and women, there was an inverse association of cIMT with CRF, which was observed in both overweight/mild obesity and normal-weight individuals, highlighting the importance of endurance capacity on reducing risk of early atherosclerosis and implying that the moderation effect of body adiposity might not be present in this population.

Project description:This study aimed to investigate the association of periodontitis with subclinical atherosclerosis in young adults. In total, 486 non-diabetic military personnel were included in Taiwan. Carotid intima-media thickness (cIMT) was assessed utilizing sonography for subclinical atherosclerosis. Periodontitis severity was defined based on the 2017 US/European consensus. Mean cIMT was compared by analysis of covariance (ANCOVA), and multiple logistic regression model was used to determine the association of periodontitis severity and the highest quintile of cIMT (≥ 0.8 mm) with adjustments for age, sex, metabolic risk factors and leukocyte counts. The mean cIMT increased in those with greater stages (periodontal health (N = 349): 0.65 mm, Stage I (N = 41): 0.72 mm, Stage II (N = 57): 0.74 mm and Stage III: 0.76 mm, respectively, p < 0.01). In multiple logistic regression, a dose-response association from Stage I to Stage III periodontitis for cIMT ≥ 0.8 mm was also found [ORs and 95% CIs 1.41 (0.60-3.29), 1.62 (0.79-3.31) and 3.20 (1.42-7.18)]. Leucocyte counts ≥ 7.6 × 103/µL (the highest quintile) was associated with cIMT ≥ 0.8 mm [OR 1.86 (1.11-3.12)], while no association existed for other metabolic risk factors. In conclusion, severe periodontitis and leukocyte counts are independent risk factors of increased cIMT, emphasizing the critical role of inflammation in subclinical atherosclerosis.

Project description:BackgroundThe purpose of this study was to determine if subclinical markers of atherosclerosis are associated with a decline in olfactory function.MethodsThe San Diego Odor Identification Test was administered to 2,302 participants (age 21-84 years) at the baseline (2005-2008) and 5-year follow-up (2010-2013) examinations of the Beaver Dam Offspring Study. A decline in odor identification was defined as a decrease in San Diego Odor Identification Test score of 2 or more (range 0-8) from Beaver Dam Offspring Study 1 to Beaver Dam Offspring Study 2. Carotid intima media thickness and plaque, blood pressure, pulse wave velocity, and body mass index were measured and other risk factor data were obtained by interview.ResultsOverall 3.2% of participants had a decline in San Diego Odor Identification Test score at 5 years. In age- and sex-adjusted models, mean intima media thickness (odds ratio = 1.17, 95% CI = 1.01, 1.34, per 0.1 mm) and number of sites (range 0-6) with carotid artery plaque (odds ratio = 1.35, 95% CI = 1.11, 1.65, per site) at baseline were associated with an increased risk for decline. Plaque score (odds ratio = 1.24, 95% CI = 1.01, 1.53) remained a significant independent predictor of olfactory decline in a model that included age, sex, hypertension, body mass index, alcohol, and smoking.ConclusionsSubclinical atherosclerosis was associated with an increased risk for olfactory decline indicating that atherosclerosis may be one of the risk factors for the decline in olfactory function seen with aging. Strategies to improve vascular health may also benefit olfactory health.

Project description:Background and objectivesAltered levels of atherogenic lipoproteins have been shown to be common in mild kidney dysfunction. This study sought to determine the associations between plasma lipids (including LDL particle distribution) and subclinical atherosclerosis measured by the common carotid intima-media thickness (IMT) across levels of estimated GFR (eGFR) and to assess whether inflammation modifies these associations.Design, setting, participants, & measurementsCross-sectional analyses of 6572 participants in the Multi-Ethnic Study of Atherosclerosis enrolled from 2000 to 2002 were performed.ResultsCKD, defined as eGFR <60 ml/min per 1.73 m(2), was present in 853 individuals (13.0%). Associations of total cholesterol and LDL cholesterol (LDL-C) with IMT were J shaped, particularly among participants with CKD (P value for interaction, P=0.01). HDL cholesterol (HDL-C) and small-dense LDL-C were consistently and linearly associated with IMT across levels of eGFR. The results showed differences in IMT of -21.41 (95% confidence interval, -41.00, -1.57) in eGFR ≥60 and -58.49 (-126.61, 9.63) in eGFR <60 per unit difference in log-transformed HDL-C, and 4.83 (3.16, 6.50) in eGFR ≥60 and 7.48 (1.45, 13.50) in eGFR <60 per 100 nmol/L difference in small-dense LDL. Among participants with CKD, inflammation significantly modified the associations of total cholesterol and LDL-C with IMT (P values for interaction, P<0.01 and P<0.001, respectively).ConclusionsCompared with total cholesterol and LDL-C, abnormalities in HDL-C and small-dense LDL-C are more strongly and consistently associated with subclinical atherosclerosis in CKD. Inflammation modifies the association between total cholesterol and LDL-C with IMT.

Project description:Carotid artery intima-media thickness (IMT) is a marker of cardiovascular disease associated with incident stroke. We studied whether IMT rate of change is associated with stroke.We studied 5028 participants of the Multi-Ethnic Study of Atherosclerosis (MESA) comprising white, Chinese, Hispanic, and black participants free of cardiovascular disease. In this MESA IMT progression study, IMT rate of change (mm/year) was the difference in right common carotid artery far wall IMT (mm) divided by the interval between 2 ultrasound examinations (median interval, 32 months). Common carotid artery IMT was measured in a region free of plaque. Cardiovascular risk factors and baseline IMT were determined when IMT rate of change was measured. Multivariable Cox proportional hazards models generated hazard risk ratios (HR) with cardiovascular risk factors, ethnicity, and education level/income as predictors.There were 42 first-time strokes seen during a mean follow-up of 3.22 years (median, 3.0 years). Average age was 64.2 years, with 48% males. In multivariable models, age (HR, 1.05 per year), systolic blood pressure (HR, 1.02 per mm Hg), lower high-density lipoprotein cholesterol levels (HR, 0.96 per mg/dL), and IMT rate of change (HR, 1.23 per 0.05 mm/year; 95% confidence limit, 1.02-1.48) were significantly associated with incident stroke. The upper quartile of IMT rate of change had HR of 2.18 (95% confidence limit, 1.07-4.46) compared to the lower 3 quartiles combined.Common carotid artery IMT progression is associated with incident stroke in this cohort free of prevalent cardiovascular disease and atrial fibrillation at baseline.

Project description:Carotid intima-media thickness (cIMT), a marker of subclinical atherosclerosis, has been found to be associated with incident stroke. High-sensitivity C-reactive protein (CRP) and fibrinogen have been demonstrated to be associated with atherosclerosis. Previous studies on heritability estimates of IMT, CRP, and fibrinogen among Chinese populations are limited. This study aims to estimate the heritability of these risk factors in residents who participated in the Taichung Community Health Study (TCHS) and their family members. A total of 2671 study subjects from 805 families were enrolled in the study, selected from a random sample of TCHS participants and their family members. CRP, and fibrinogen were obtained from each participant, and a questionnaire interview was conducted. cIMT was measured by high-resolution B-mode ultrasound and expressed as the mean of the maximum. Heritability estimates and the familial correlation of cIMT, CRP, and fibrinogen among family pairs were determined with SAGE software. With multivariate adjustments, significant heritability was found for cIMT (h2 = 0.26, P < 0.001), CRP (h2 = 0.34, P < 0.001), and fibrinogen (h2 = 0.48, P < 0.001). The intrafamilial correlation coefficients for the three indexes in the parent-offspring pairs were significant (P < 0.001) and ranged from 0.17 to 0.41. The full sibship correlations were also significant (P < 0.001) for the three indexes and ranged from 0.19 to 0.47. This study indicates that a moderate proportion of the variability in CRP, fibrinogen, and cIMT can be attributed to genetic factors in Chinese populations. The findings suggest that CRP is associated with cIMT, whereas no significant association exists between fibrinogen and cIMT.

Project description:BackgroundBoth hypertensive and atherosclerotic processes contribute to common carotid artery intima-media thickness (CCA-IMT). Elevated CCA-IMT may be indicative of subclinical cerebrovascular disease; however, its role in the absence of concomitant carotid artery plaque is uncertain, and few studies have examined associations in Black populations.Materials and methodsAt cohort visit 3 (1993-1995) a subset of stroke-free participants (641 Blacks and 702 Whites, mean age 63) from the Atherosclerosis Risk in Communities (ARIC) study was imaged by brain MRI and carotid ultrasound. A CCA-IMT >0.9 mm was considered elevated. Asymptomatic brain lesions ≥3 mm were considered silent brain infarctions (SBI). Subcortical SBI measuring 3 to <20 mm were considered lacunes. Associations between elevated CCA-IMT and SBI were analyzed with Poisson regression.ResultsElevated CCA-IMT was identified in 168 participants (16% of Blacks, 10% of Whites), and SBI were observed in 156 (15% of Blacks, 8% of Whites). Elevated CCA-IMT was strongly related to anterior circulation SBI, posterior circulation SBI, and lacunes. After adjustments, elevated CCA-IMT remained associated with greater number of lacunes in Blacks ([prevalence ratio, PR] = 1.60; 95% confidence interval [CI]: 1.02-2.51), but not Whites (PR = 0.85; 95% CI: 0.35-2.04); P value for interaction = 0.12. Among Black participants without concomitant carotid plaque, elevated CCA-IMT was associated with twice the number of lacunes (PR = 2.00; 95% CI: 1.05-3.82).ConclusionsIn older Black adults, elevated CCA-IMT is independently associated with lipohyalinosis of the cerebral small vessels, irrespective of concomitant carotid plaque and vascular risk factors.

Project description:AimsCarotid intima-media thickness (CIMT) and plaque information can improve coronary heart disease (CHD) risk prediction when added to traditional risk factors (TRF). However, obtaining adequate images of all carotid artery segments (A-CIMT) may be difficult. Of A-CIMT, the common carotid artery intima-media thickness (CCA-IMT) is relatively more reliable and easier to measure. We evaluated whether CCA-IMT is comparable to A-CIMT when added to TRF and plaque information in improving CHD risk prediction in the Atherosclerosis Risk in Communities (ARIC) study.Methods and resultsTen-year CHD risk prediction models using TRF alone, TRF + A-CIMT + plaque, and TRF + CCA-IMT + plaque were developed for the overall cohort, men, and women. The area under the receiver operator characteristic curve (AUC), per cent individuals reclassified, net reclassification index (NRI), and model calibration by the Grønnesby-Borgan test were estimated. There were 1722 incident CHD events in 12 576 individuals over a mean follow-up of 15.2 years. The AUC for TRF only, TRF + A-CIMT + plaque, and TRF + CCA-IMT + plaque models were 0.741, 0.754, and 0.753, respectively. Although there was some discordance when the CCA-IMT + plaque- and A-CIMT + plaque-based risk estimation was compared, the NRI and clinical NRI (NRI in the intermediate-risk group) when comparing the CIMT models with TRF-only model, per cent reclassified, and test for model calibration were not significantly different.ConclusionCoronary heart disease risk prediction can be improved by adding A-CIMT + plaque or CCA-IMT + plaque information to TRF. Therefore, evaluating the carotid artery for plaque presence and measuring CCA-IMT, which is easier and more reliable than measuring A-CIMT, provide a good alternative to measuring A-CIMT for CHD risk prediction.
