  • The Cardiovascular Health Diet Index (CHDI) is a diet quality score based on the dietary guidelines of the American Heart Association for cardiovascular health but with some adaptations, such as red meat, dairy products, beans and ultra-processed foods in its components. The CHDI has shown good relative validity parameters; however, its association with health outcomes is still unclear. Thus, our aim was to investigate the association between the CHDI score with subclinical atherosclerosis. Data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) cohort were used. Subclinical atherosclerosis was assessed by measuring coronary artery calcification at baseline (2008–2010) and second wave (2012–2014) and carotid intima-media thickness at baseline and at the third wave (2017–2019). The CHDI score (ranges from 0 to 110 points) was applied to dietary data obtained from an FFQ at baseline. Poisson regression with robust variance, linear regression and linear mixed-effects models were used to evaluate the association of the CHDI score with coronary artery calcification incidence (n 2224), coronary artery calcification progression (n 725) and changes in carotid intima-media thickness (n 7341) over time, respectively. After a median 8-year follow-up period, a 10-point increase in the CHDI score was associated with a decrease in carotid intima-media thickness of 0·002 mm (95 % CI –0·005, –0·001). No association was observed between the CHDI score and coronary artery calcification incidence and progression after a 4-year follow-up period. Higher scores in the CHDI were prospectively associated with decreased subclinical atherosclerosis after an 8-year follow-up period.

  • Background:

    Vesicoureteral reflux is a prominent congenital anomaly of the kidney and the urinary tract. Further, renal scarring is known to be related to chronic inflammation. However, there have been limited studies to date regarding the cardiovascular consequences of vesicoureteral reflux.

    Objective:

    The aim of this study is to evaluate the possible subclinical atherosclerosis and cardiovascular complications in children with vesicoureteral reflux.

    Methods:

    Patients with vesicoureteral reflux and age matched healthy controls were prospectively included in this case-control study. Patients were divided into two groups concerning renal scarring status. To assess cardiac functions, carotid artery intima media, epicardial adipose tissue, and periaortic adipose tissue thicknesses were evaluated.

    Results:

    There were 50 patients with vesicoureteral reflux; 26 patients without renal scarring and 24 patients with renal scarring, as well as 40 healthy controls. Myocardial performance indexes (Tei indexes) measured by tissue Doppler echocardiography from septum and left ventricle were significantly increased in study group (for all, p < 0.001). Also, intima media, epicardial adipose tissue, and periaortic adipose tissue thicknesses of the study groups were significantly higher than the control group (for all, p < 0.001). However, no statistical difference was observed between renal scarring (−) and renal scarring (+) groups.

    Conclusions:

    Results of our study showed early deterioration of cardiac systolic and diastolic functions in children with vesicoureteral reflux regardless of renal scarring. Also, diagnosis of vesicoureteral reflux is an important risk factor for subclinical atherosclerosis, independent of renal scarring, which should be considered in the follow-up of these patients.

  • Background:

    Subclinical atherosclerosis in childhood can be evaluated by carotid intima-media thickness, which is considered a surrogate marker for atherosclerotic disease in adulthood. The aims of this study were to evaluate carotid intima-media thickness and, to investigate associated factors.

    Methods:

    Cross-sectional study with children and adolescents with congenital heart disease (CHD). Socio-demographic and clinical characteristics were assessed. Subclinical atherosclerosis was evaluated by carotid intima-media thickness. Cardiovascular risk factors, such as physical activity, screen time, passive smoke, systolic and diastolic blood pressure, waist circumference, dietary intake, lipid parameters, glycaemia, and C-reactive protein, were also assessed. Factors associated with carotid intima-media thickness were analysed using multiple logistic regression.

    Results:

    The mean carotid intima-media thickness was 0.518 mm and 46.7% had subclinical atherosclerosis (carotid intima-media thickness ≥ 97th percentile). After adjusting for confounding factors, cyanotic CHD (odds ratio: 0.40; 95% confidence interval: 0.20; 0.78), cardiac surgery (odds ratio: 3.17; 95% confidence interval: 1.35; 7.48), and be hospitalised to treat infections (odds ratio: 1.92; 95% confidence interval: 1.04; 3.54) were associated with subclinical atherosclerosis.

    Conclusion:

    Clinical characteristics related to CHD were associated with subclinical atherosclerosis. This finding suggests that the presence of CHD itself is a risk factor for subclinical atherosclerosis. Therefore, the screen and control of modifiable cardiovascular risk factors should be made early and intensively to prevent atherosclerosis.

  • 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 (5th v. 1st quintile, OR 0·64, 95 % CI 0·45, 0·90, P for trend = 0·069; 5th v. 1st quintile, OR 0·34, 95 % CI 0·16, 0·70, P for 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.
