Background and Purpose: Cerebral atherosclerosis is the leading cause of mechanical obstruction of blood flow that final event is cerebral infarction. Lipoprotein-associated phospholipase A2 (Lp-PLA2) is an inflammatory biomarkers specific for blood vessels, is an important factor predicted extent of atherosclerosis. The study aimed to assess the association between serum Lp-PLA2 concentration with carotid intimamedia thickness (IMT). Materials andMethod: The cross – sectional study, in 37 patients who presented to Department of Cardiology - Hue University Hospital and Hue Central Hospital. Vulnerability asessment of the external carotid artery into the skull through ultrasound by measuring carotid intima-media thickness. Testing serum Lp-PLA2 concentration, lipid profile, blood glucose. Results: Group of patients with thickness of carotid IMT levels of serum Lp-PLA2 was 27.73 IU/ml higher than the group with thickness normal carotid IMT was 14.35 IU/ml; p < 0.05. Total cholesterol, LDL cholestrol, triglycerid and Lp-PLA2 are the factors capable of predict the changes in size IMT; (p <0.05). There is moderate correlation between Lp-PLA2 levels and carotid intima-media thickness (r = 0.47; p < 0.05). Conclusion: Higher Lp-PLA2 levels is significantly associated with carotid intimamedia thickness in patients who have cerebral infarction. Key words: Stroke, atherosclerosis, inflammation, biomarker.

ObjectivesTo describe a well-established marker of cardiovascular risk, carotid intima–media thickness (IMT) and related measures (artery distensibility and elasticity) in children aged 11–12 years old and mid-life adults, and examine associations within parent–child dyads.DesignCross-sectional study (Child Health CheckPoint), nested within a prospective cohort study, the Longitudinal Study of Australian Children (LSAC).SettingAssessment centres in seven Australian major cities and eight selected regional towns, February 2015 to March 2016.ParticipantsOf all participating CheckPoint families (n=1874), 1489 children (50.0% girls) and 1476 parents (86.8% mothers) with carotid IMT data were included. Survey weights and methods were applied to account for LSAC’s complex sample design and clustering within postcodes and strata.Outcome measuresUltrasound of the right carotid artery was performed using standardised protocols. Primary outcomes were mean and maximum far-wall carotid IMT, quantified using semiautomated edge detection software. Secondary outcomes were carotid artery distensibility and elasticity. Pearson’s correlation coefficients and multivariable linear regression models were used to assess parent–child concordance. Random effects modelling on a subset of ultrasounds (with repeated measurements) was used to assess reliability of the child carotid IMT measure.ResultsThe average mean and maximum child carotid IMT were 0.50 mm (SD 0.06) and 0.58 mm (SD 0.05), respectively. In adults, average mean and maximum carotid IMT were 0.57 mm (SD 0.07) and 0.66 mm (SD 0.10), respectively. Mother–child correlations for mean and maximum carotid IMT were 0.12 (95% CI 0.05 to 0.23) and 0.10 (95% CI 0.03 to 0.21), respectively. For carotid artery distensibility and elasticity, mother–child correlations were 0.19 (95% CI 0.10 to 0.25) and 0.11 (95% CI 0.02 to 0.18), respectively. There was no strong evidence of father–child correlation in any measure.ConclusionsWe provide Australian values for carotid vascular measures and report a modest mother–child concordance. Both genetic and environmental exposures are likely to contribute to carotid IMT.

Introduction: Cardiovascular diseases (CVDs) are the main cause of morbidity and mortality in RA disease. In active RA patients, the majority of cardiovascular deaths result from accelerates atherosclerosis. Aim of the Work: The aim of this work is to assess carotid intima media thickness (C-IMT) and endothelial function by brachial artery flow mediated dilatation (FMD) in Rheumatoid arthritis patients and relation to the disease activity. Subjects and Methods: Our study included 50 RA patients, from Tanta University Hospital. 47 women and 3 men and their age ranged from 30-62 years.  They were divided into group 1:  25 active RA patients, group 2:  25 inactive RA patients who were   diagnosed by American College of Rheumatology (ACR) revised criteria for diagnosis of RA 1987 and disease activity was evaluated using disease activity score 28(DAS28). Group 3: 25 normal subjects as a control group.  We measured C-IMT and FMD in all groups. Results: By comparing the groups, we found that active RA patients had increased C-IMT compared to inactive rheumatoid arthritis patients and controls which is indicator of atherosclerosis. FMD of the brachial artery impaired in RA patients compared to controls which is indicator of endothelial dysfunction. There was highly statistically significant relation between duration, activity of RA disease and atherosclerosis in RA patients. Conclusion: With increasing the frequency of atherosclerosis in asymptomatic RA patients, carotid IMT increased and FMD impaired when compared with general population. Active RA patients have increased carotid IMT and impaired FMD compared with inactive RA patients.

Oxidative stress is the major cause of atherosclerosis and cardiovascular diseases. This cross-sectional study is aimed at determining if parallel serum markers of oxidative stress are related to carotid intima-media thickness (IMT). We enrolled 134 participants with varied metabolic syndrome (Met-S) scores (zero, n=21; one, n=19; two, n=27; three, n=26; four, n=25; five, n=16). Biochemical profiles and potential oxidative stress biomarkers malondialdehyde (MDA) and uric acid were measured in fasting plasma. We found that carotid IMT positively correlated with both MDA and uric acid levels. Multivariate analysis revealed that both MDA (p<0.05) and uric acid (p<0.01) levels were significantly associated with carotid IMT in participants whose Met-S scores were ≥1 or ≥2. However, only uric acid (p<0.01) levels were positively associated with carotid IMT in patients with metabolic syndrome. Linear regression model analysis revealed that the prediction accuracies for carotid IMT from MDA combined with uric acid and from a combination of MDA, uric acid, and Met-S score were 0.176 and 0.237, respectively. These were better than the predication accuracies from MDA (r2=0.075) and uric acid (r2=0.148) individually. These results suggest that measuring uric acid levels along with MDA biomarkers and Met-S scores may be a promising step in the development of an effective model for monitoring the severity of carotid IMT and atherosclerosis in the patients with metabolic syndrome.

The Relationship

The relationship between dietary Zn intake and the risk of atherosclerosis remains unclear, and no epidemiological studies have been reported on the effects of dietary Zn intake on morphological changes in the vascular wall. We examined the relationship between dietary Zn intake and common carotid intima-media thickness (IMT) as a marker of subclinical atherosclerosis among the middle-aged and elderly populations. A cross-sectional analysis of a prospective cohort baseline study was performed with 4564 adults aged 40–89 years and free of clinical CVD. Dietary data were collected by trained interviewers using an FFQ. Common carotid IMT was measured using a B-mode ultrasound imaging technique. Subclinical atherosclerosis was determined using carotid IMT, and defined as >80th percentile of carotid IMT or ≥ 1 mm of carotid IMT. After adjustment for potential confounders, the mean carotid IMT in the low Zn intake group was higher than that in the high Zn intake group. When subclinical atherosclerosis was defined as >80th percentile value of IMT or ≥ 1 mm of carotid IMT, after adjustment for potential confounders, Zn intake was inversely related to subclinical atherosclerosis (5thv.1st quintile, OR 0·64, 95 % CI 0·45, 0·90,Pfor trend = 0·069; 5thv.1st quintile, OR 0·34, 95 % CI 0·16, 0·70,Pfor trend = 0·005, respectively). In persons free of clinical CVD, dietary Zn intake was inversely correlated with subclinical atherosclerosis. The present findings suggest a putative protective role of dietary Zn intake against the development of atherosclerosis.

Background:Rheumatoid arthritis (RA) is chronic inflammatory rheumatism characterized by an independent cardiovascular (CV) risk. The screening of carotid intima-media thickness (IMT) in the common carotid artery appears to be a marker of atherosclerosis and is used as a specific tool for CV risk assessment.Objectives:The main of this study was to determine the most associated US sites with CV risk in RA.Methods:The present study is a prospective study conducted on Tunisian RA patients in rheumatology department of Mohamed Kassab University Hospital (March and December 2020). The characteristics of the patients and those of the disease were collected. The measurement of cIMTwas done using high-resolution B-mode carotid US with a Philips machine with the patient in supine position, according to AmericanSociety of Echocardiography guidelines.The carotid bulb below itsbifurcation and the internal and external carotid arteries were evaluated bilaterally with gray scale, spectral and color Doppler ultra-sonography using proprietary software for carotid arterymeasurements.IMT was measured using the two inner layers of the commoncarotid artery and an increased IMT was defined as ≥0.9 mm. The CV risk at 10 years was calculated by the SCORE index.Results:Forty-seven patients were collected, of which 78.7% were women. The mean age was 52.5 ±11.06 years. The rheumatoid factor (RF) was positive in 57.8% of cases, and anti-citrullinated peptide antibodies (ACPA) were positive in 62.2% of cases. RA was erosive in 81.6% of cases. Hypertension (hypertension) was present in 14.9% of patients and diabetes in 12.8% of patients. Nine patients were active smokers. The mean IMT in the left common carotid (LCC) was 0.069 ±0.015, in the left internal carotid (LIC) was 0.069 ±0.015, in the left external carotid (LEC) was 0.060 ±0.023. The mean IMT was 0.068 ±0.01 in the right common carotid (RCC), 0.062 ±0.02 in the right internal carotid (RIC), and 0.060 ±0.016 in the right external carotid (REC). The mean SCORE index of CV risk was 2±2.81 [0-11.6]. CV risk was significantly associated with the IMTs for LIC (p=0.029; r=0.374), LEC (p=0.04; r=0.480), and REC (p=0.016; r=0.408). No association was found between the IMT in the LCC (p=0,361; r=0,162), neither in the RCC (p=0,438; r=0,140) nor the RIC (p=0,670; r=0,077).Conclusion:In our study, IMT is strongly associated with score index, especially in carotid bifurcation. However, IMT measured in common carotid does not reflect a cardiovascular risk at 10-years.References:[1]S. Gunter and al.
