Whereas some previous data on carriers with isolated antiphospholipid antibodies positivity (APP) suggested an increased risk of arterial events in this clinical setting, no data are available on subclinical atherosclerosis in this clinical setting. This article reports data on intima-media thickness of the common carotid artery (CCA-IMT) and of the Bulb (Bulb-IMT) and on the prevalence of carotid plaques in APP carriers and in subjects with antiphospholipid syndrome (APS) specifically stratifyi ...[more]

Project description:BackgroundThe cardiovascular risk models and subclinical atherosclerotic indicators are both recommended for cardiovascular risk stratification. The accordance between the incidence of subclinical atherosclerosis and subjects with low and moderate cardiovascular risk is unclear.HypothesisSubjects with low and moderate cardiovascular risk have a lower incidence of subclinical atherosclerosis compared with subjects with high risk.MethodsBrachial-ankle pulse wave velocity (BaPWV) and brachial flow-mediated dilation (BFMD) were measured in 421 subjects without a history of atherosclerotic cardiovascular disease (ASCVD) from October 2016 to January 2020. All subjects were classified into low, moderate, and high risk based on Framingham and China-par risk models respectively.ResultsMean age was 57.05 ± 9.35 years and 248 (58.9%) were male. In subjects with low, moderate, and high risk assessed by Framingham and China-par risk models, the percentage of abnormal BaPWV ( > 1400 cm/s) was 42.9%, 70.1%, 85.7%, and 40.4%, 71.4%, 89.7%, respectively. Meanwhile, the percentage of abnormal BFMD ( ≤ 7%) was 43.8%, 68.5%, 77.3%, and 44.9%,72.1%, and 76.6%. According to Framingham-based high-risk categories, positive predictive value (PPV), negative predictive value (NPV), sensitivity and specificity for BaPWV abnormality were 85.7%, 39.4%, 36.1%, and 87.5%, respectively. For BFMD abnormality, the values were 77.3%, 40.1%, 34.1%, and 81.8%, respectively. According to China-par high-risk categories, the values for BaPWV abnormality were 89.7%, 43.8%, 45.6%, and 89.0%, respectively. For BFMD abnormality, the values were 76.6%, 41.3%, 40.7%, and 77%, respectively. In multivariate analysis, age and blood pressure were the independent predictors for subclinical atherosclerosis in subjects with low-moderate risk.ConclusionsMore than one-half of subjects with low and moderate risk already have detectable subclinical atherosclerosis, indicating higher cardiovascular risk beyond the traditional stratification.

Project description:BackgroundThe effect of subclinical thyroid dysfunction on vascular atherosclerosis remains uncertain. The objective of this study was to elucidate the association between sustained subclinical thyroid dysfunction and carotid plaques, which are an early surrogate marker of systemic atherosclerosis.MethodsThe study included 21,342 adults with consistent thyroid hormonal status on serial thyroid function tests (TFTs) and carotid artery duplex ultrasonography at a health screening center between 2007 and 2014. The effect of subclinical thyroid dysfunction on baseline carotid plaques and newly developed carotid plaques during 5-year follow-up was determined by logistic regression analyses and GEE (Generalized Estimating Equations), respectively.ResultsCarotid plaques were more common in the subclinical hypothyroidism (55.6%) than the euthyroidism (47.8%) at baseline. However, in multivariable analysis, thyroid status was not a significant risk for the carotid plaques at baseline. Instead, traditional cardiovascular risk factors, such as age (P <0.001), systolic blood pressure (P = 0.023), fasting blood glucose (P = 0.030), and creatinine (P = 0.012) were associated with baseline carotid plaques in subclinical hypothyroidism. In longitudinal analyses of subjects who were followed up for more than 5 years, there was no significant difference in the cumulative incidence of new carotid plaques according to time between subjects with subclinical hypothyroidism and those with euthyroidism (P = 0.392).ConclusionsSustained subclinical thyroid dysfunction did not affect the baseline or development of carotid plaques in healthy individuals.

Project description:ObjectiveGenetic variants robustly associated with coronary artery disease were reported in the vicinity of the interleukin (IL)-5 locus, and animal studies suggested a protective role for IL-5 in atherosclerosis. Therefore, we set this work to explore IL-5 as a plasma biomarker for early subclinical atherosclerosis, as determined by measures of baseline severity and change over time of carotid intima-media thickness (cIMT).MethodsWe used biobank and databases of IMPROVE, a large European prospective cohort study of high-risk individuals (n = 3534) free of clinically overt cardiovascular disease at enrollment, in whom composite and segment-specific measures of cIMT were recorded at baseline and after 15 and 30 months. IL-5 was measured with an immunoassay in plasma samples taken at baseline.ResultsIL-5 levels were lower in women than in men, lower in the South than in North of Europe, and showed positive correlations with most established risk factors. IL-5 showed significant inverse relationships with cIMT change over time in the common carotid segment in women, but no significant relationships to baseline cIMT in either men or women.ConclusionsOur results suggest that IL-5 may be part of protective mechanisms operating in early atherosclerosis, at least in women. However, the relationships are weak and whereas IL-5 has been proposed as a potential molecular target to treat allergies, it is difficult to envisage such a scenario in coronary artery disease.

Project description:BackgroundIdeal cardiovascular (CV) health by simultaneous presence of 7 ideal health metrics (blood pressure, cholesterol, glucose, smoking, BMI, physical activity and diet) has been defined by the American Heart Association. In the current study we investigated the association of a CV health score (range 0-14), on the extent and progression of carotid atherosclerosis, assessed as carotid intima-media thickness (cIMT) and total plaque area (TPA) by ultrasound at 5 years interval.Methods and resultsA total of 219 participants (age 75.6 ± 5.1) from the Age, Gene/Environment Susceptibility (AGES)-Reykjavik study were studied. Men with poor (low) CV health score had greater TPA than those with more optimal (high) score (61.5 (SD: 32.3), 44.4 (24.2) and 37.7 (23.2) mm(2) for those with CV health score ≤6, 7-9 and ≥10 respectively, p < 0.05). In linear analysis for men, log TPA was 0.088 mm(2) (SE: 0.040 p < 0.05) smaller for each additional point in the CV health score. CV health score was not associated with TPA in women, or cIMT in either sex. TPA increased in both sexes between visits. However, CV health score did not predict carotid atherosclerosis progression.ConclusionsCV health score is associated with TPA in older men but not in women. Men with poor CV health score at the baseline visit had more extensive carotid atherosclerosis than those with better CV health score, although it did not predict the progression of carotid atherosclerosis.

Project description:ObjectiveBoth periodontal disease and cardiovascular disease (CVD) are overrepresented in rheumatoid arthritis (RA). This study was undertaken to investigate the contribution of periodontal pathogens to CVD in RA.MethodsRA patients underwent assessments of coronary artery calcification (CAC), carotid intima-media thickness and plaque, and ankle-brachial index via computed tomography, ultrasound, and Doppler ultrasound, respectively. Sera were assayed for antibodies targeting Porphyromonas gingivalis (Pg), Aggregatibacter actinomycetemcomitans serotype B (Aa), and Aa-derived leukotoxin A (LtxA). Associations of antibodies against these periodontal pathogens with measures of atherosclerosis were explored using generalized linear models.ResultsAmong 197 RA patients, anti-Pg was detected in 72 patients (37%), anti-Aa in 41 patients (21%), and anti-LtxA in 84 patients (43%). Adjusting for relevant confounders and reported tooth loss, the mean CAC score was 90% higher in those with anti-Aa and/or anti-LtxA compared with those without either antibody (19 units versus 10 units; P = 0.033). The adjusted odds of CAC ≥100 units were 2.23-fold higher in those with anti-Aa and/or anti-LtxA compared with those without either antibody (P = 0.040). Anti-Aa and/or anti-LtxA seropositivity was significantly associated with all other assessed measures of atherosclerosis except carotid plaque. Anti-Pg was not associated with any measure of atherosclerosis. Higher swollen joint count was associated with CAC exclusively in the group with anti-Aa and/or anti-LtxA.ConclusionImmunoreactivity against Aa and/or its major virulence factor LtxA was associated with atherosclerosis in multiple vascular beds of RA patients and amplified the effect of swollen joints on coronary atherosclerosis, suggesting a role for treatment/prevention of periodontal disease in the prevention of CVD in RA.

Project description:BACKGROUND AND AIMS:Examine age, sex, race, and socioeconomic status as modifiers of the association between carotid intimal medial thickness (IMT) and neurocognitive performance in a socioeconomically diverse, biracial, urban, adult population. METHODS:Participants were 1712 community-dwelling adults (45% men, 56% African-American, 38% below poverty threshold, aged 30-64 years) enrolled in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. Participants underwent initial carotid ultrasonography followed by cognitive testing on up to two occasions over 4 years. Mixed-effects regression analyses were adjusted for demographic, behavioral, and biomedical covariates. RESULTS:Significant cross-sectional IMT × race × poverty interactions were identified for measures of delayed recall memory, auditory-verbal attention, and working memory. An IMT × race interaction also appeared for auditory-verbal learning. Higher IMT was generally associated with worse cognitive performance, but the disadvantage was most pronounced among those with higher socioeconomic status and white participants. No longitudinal associations were identified. CONCLUSIONS:Carotid IMT-cognition associations differed as a function of race and socioeconomic status and were most compelling for measures of attention, executive function, and memory. These findings highlight the possibility that subclinical atherosclerosis may be differentially informative as a predictor of cognitive performance among varied demographic subgroups.

Project description:BackgroundIndividuals infected with human immunodeficiency virus (HIV) live longer as a result of effective treatment, but long-term consequences of infection, treatment, and immunological dysfunction are poorly understood.MethodsWe prospectively examined 1011 women (74% HIV-infected) in the Women's Interagency HIV Study and 811 men (65% HIV-infected) in the Multicenter AIDS Cohort Study who underwent repeated B-mode carotid artery ultrasound imaging in 2004-2013. Outcomes included changes in right common carotid artery intima-media thickness (CCA-IMT) and new focal carotid artery plaque formation (IMT >1.5 mm) over median 7 years. We assessed the association between HIV serostatus and progression of subclinical atherosclerosis, adjusting for demographic, behavioral, and cardiometabolic risk factors.ResultsUnadjusted mean CCA-IMT increased (725 to 752 µm in women, 757 to 790 µm in men), but CCA-IMT progression did not differ by HIV serostatus, either in combined or sex-specific analyses. Focal plaque prevalence increased from 8% to 15% in women and 25% to 34% in men over 7 years. HIV-infected individuals had 1.6-fold greater risk of new plaque formation compared with HIV-uninfected individuals (relative risk [RR] 1.61, 95% CI, 1.12-2.32), adjusting for cardiometabolic factors; the association was similar by sex. Increased plaque occurred even among persistently virologically suppressed HIV-infected individuals compared with uninfected individuals (RR 1.56, 95% CI, 1.07-2.27). HIV-infected individuals with baseline CD4+ ? 500 cells/µL had plaque risk not statistically different from uninfected individuals.ConclusionsHIV infection is associated with greater increases in focal plaque among women and men, potentially mediated by factors associated with immunodeficiency or HIV replication at levels below current limits of detection.

Project description:Background Assessing and optimizing cardiovascular health (CVH) early in life, such as in pregnancy, could lead to a longer lifetime spent in better CVH and reduce the risk of cardiovascular disease. This might especially benefit women with a hypertensive disorder of pregnancy (HDP) who are more likely to develop atherosclerosis and cardiovascular disease. We hypothesized that CVH in pregnancy is related to later life CVH and carotid intima-media thickness (CIMT), and that these associations differ between women with a normotensive pregnancy and women with an HDP. Methods and Results This study was conducted within the prospective population-based Generation R Study. CVH in pregnancy was based on 5 metrics (blood pressure, total-cholesterol, glucose, smoking, and body mass index). Postpartum CVH additionally included physical activity and diet scores, according to the American Heart Association classification. Postpartum CVH and CIMT were measured 10 years after pregnancy. Results were analyzed for women with a normotensive pregnancy and those with an HDP. Women with a normotensive pregnancy (n=1786) and women with an HDP (n=138) were evaluated from early pregnancy until 10 years postpartum. Better CVH in early pregnancy was associated with a smaller CIMT and better postpartum CVH in all women, especially in those with an HDP (CIMT: -9.82 ?m [95% CI: -17.98, -1.67]). Conclusions Already in pregnancy, better CVH is associated with a smaller CIMT and better CVH 10 years postpartum, especially in women with an HDP. As pregnancy is an incentive for women to improve lifestyle, assessing CVH in pregnancy might help improve postpartum CVH and reduce cardiovascular disease risk.

Project description:Background and Purpose- Many health effects of sleep apnea (SA) may be mediated through accelerated atherosclerosis. We examined the associations of snoring and several measurements of SA with subclinical carotid atherosclerosis in a large multiethnic population sample. Methods- This analysis included 1615 participants (mean age, 68 years) from examination 5 (2010-2013) of the MESA study (Multi-Ethnic Study of Atherosclerosis). Sleep measures including SA (apnea-hypopnea index [4%], ≥15 events/hour) were derived from full in-home polysomnography. Carotid atherosclerosis was measured using high-resolution B-mode ultrasound. Multivariable linear and logistic regression models were used to evaluate the associations between sleep exposures with carotid intima-media thickness and the presence of carotid plaque, respectively. Effect modification by age, sex, and race/ethnicity was examined. Results- In multivariable analysis, SA was associated with an increased odds of carotid plaque presence in individuals aged <68 years (odds ratio, 1.47; 95% CI, 1.05-2.06) but not in older individuals (odds ratio, 0.95; 95% CI, 0.67-1.37; P interaction=0.078). Greater hypoxemia (sleep time <90% saturation) was associated with increasing carotid intima-media thickness in younger (0.028±0.014 mm) but not in older individuals (-0.001±0.013 mm; P interaction=0.106). Self-reported snoring was not associated with carotid atherosclerosis. In assessing race-specific outcomes, greater hypoxemia was associated with increased carotid intima-media thickness in blacks (0.049±0.017 mm; P interaction=0.033). Conclusions- In this large multiethnic population-based sample, sleep disturbances are associated with subclinical carotid atherosclerosis in both men and women, particularly in those <68 years of age. The mechanisms underlying the association between SA and carotid atherosclerosis may differ for carotid plaque and carotid intima-media thickness.

Project description:ObjectiveEndothelial function and carotid intima media thickness (cIMT) were investigated in a cohort of 54 healthy adults without known cardiovascular disease.MethodsPulse wave amplitude was determined with peripheral arterial tonometry (PAT) to obtain the reactive hyperemia (RH)-PAT ratio. Ultrasound was used to determine cIMT.ResultscIMT and RH-PAT were significantly associated (rho=-0.35, P=0.02) in univariate analysis. RH-PAT was significantly associated with age, triglycerides, fasting glucose, HDL, WHR, waist circumference and VAT. cIMT was associated with age, smoking history, fasting glucose, systolic blood pressure, diastolic blood pressure and LDL. In multivariate regression analyses, triglyceride level (P=0.04) remained a significant determinant of RH-PAT whereas systolic blood pressure (P=0.02) and smoking pack-year history (P=0.046) were significant determinants of cIMT.ConclusionDeterminants of cIMT and RH-PAT were different, dominated by triglyceride and abdominal adiposity measures for RH-PAT but traditional risk factors including blood pressure, glucose, smoking and LDL for cIMT.
