Introduction: Growth hormone (GH) has been linked to cardiovascular disease and lipid metabolism but the exact mechanisms of this association are still unclear. Objectives: We here test if GH is cross-sectionally associated to carotid intima media thickness (IMT) and whether treatment with fluvastatin have any effects on the fasting level of GH in a randomized controlled trial of carotid IMT progression. Methods: We examined the association between GH and IMT in 4425 individuals (aged 46-68 years) included in the baseline examination (1991-1994) of the Malmö Diet and Cancer cardiovascular cohort (MDC-CC). From that cohort we then studied 472 individuals (aged 50-70 years) who also participated (1994-1999) in the β-Blocker Cholesterol-Lowering Asymptomatic Plaque Study (BCAPS), a randomized, double blind, placebo-controlled, single-center clinical trial. Using multivariate linear regression models we related the change in GH-levels at 12 months compared to baseline to treatment with fluvastatin. Results: In MDC-CC fasting values of GH exhibited a positive cross-sectional relation to the IMT at the carotid bifurcation after adjustment for traditional cardiovascular risk factors (p=0.002). In a gender-stratified analysis the association were positive and significant for males (p=0.005), but not for females (p=0.09). In males in BCAPS treated with fluvastatin there tended to be a greater reduction of GH after 12 months when compared to subjects not receiving fluvastatin (p=0.05) (Table). Fasting levels of GH did not interact with the different treatment regimes’ effect on the IMT. Conclusions: We here demonstrate that higher fasting levels of GH are associated to thicker IMT in the carotid bulb and that statin treatment may reduce fasting levels of GH in males. Our results are in line with previous results with GH being associated to cardiovascular disease. The effects of statin treatment on GH are small and need to be confirmed in a larger trial.

The purpose of the current investigation was to examine the cross-sectional associations of participation in muscle-strengthening activities (MSAs) with carotid intima–media thickness (CIMT) among older adults. The data are from 2,557 older adult participants enrolled in an observational cohort who reported no history of cardiovascular disease. MSA was determined using a questionnaire. Carotid ultrasound was performed to measure the CIMT of the common carotid artery bilaterally. Logistic regression models were constructed to estimate the association of MSA with CIMT after adjustment for potential confounders. The participants were aged 68.6 ± 7.0 years, and the majority were male (71.7%) and White (96.5%); 18% had abnormal CIMT. Meeting the physical activity guidelines for MSA was inversely associated with abnormal CIMT after adjustment for age and sex. However, this observed inverse relation became statistically null after further adjustment for cardiovascular disease risk factors, including aerobic physical activity.

Abstract Metabolic syndrome (MetS) and obesity are risk factors for atherosclerosis but their combined impact is unknown. The aim of this study was to quantify the added risk of obesity on carotid artery intima media thickness (cIMT), an early indicator for atherosclerosis, beyond MetS alone. The Study of Women’s Health Across the Nation (SWAN) is a multi-center, multi-ethnic cohort of women traversing the midlife into early late adulthood. cIMT was assessed between 2005-2007 and MetS, obesity and covariates were measured at the same time. This cross-sectional analysis is restricted to 1,433 women with a body mass index ≥18.5 kg/m2 and free of cardiovascular disease (CVD) when cIMT was measured. Mean maximum cIMT was related to obesity, MetS and their interaction using multivariable linear regression models. The average age was 60 years (standard deviation 2.7) and the prevalence of obesity and MetS were 44% and 35%, respectively. Both conditions occurred in 24% of women. After adjustment for age, race, smoking, family history of heart disease, and antilipemic medications, obese women had a 0.051mm (95% confidence interval (CI): 0.033,0.070; p<0.001) larger maximum cIMT versus women not obese and women with MetS had a 0.066mm (95%CI: 0.042,0.090; p<0.001) larger maximum cIMT versus women without MetS. There was a statistically significant antagonistic interaction between obesity and MetS; women with both had a mean cIMT of 0.972mm (95%CI: 0.955,0.989) and MetS alone a cIMT of 0.961mm (95%CI:0.938,0.983). This suggests that there is only a small risk of obesity on augmenting cIMT beyond MetS alone.

Background: In several statin trials, vascular event rates for treatment groups begin to separate 1 year after commencement of treatment. For atherosclerosis progression, the temporal sequence of the effect has not been defined. We sought to determine the earliest time point at which significant differences in atherosclerosis progression rates were detectable after initiation of statin therapy using data from the METEOR trial (Measuring Effects on intima media Thickness: an Evaluation Of Rosuvastatin). Methods: METEOR was a double-blind, randomized, placebo-controlled trial among 984 low risk subjects, which studied the effect of LDL lowering with 40 mg rosuvastatin on the rate of change in carotid intima media thickness (CIMT) over time. Ultrasound assessments were made at 12 carotid artery sites at baseline and every 6 months up to two years. In these analyses, the data were cut at 6 months, 1 year, and 18 months, and compared with analysis of all data at 2 years, using the same statistical method. Results: The difference in rate of maximum CIMT progression for all carotid artery sites (primary endpoint - near and far walls of the left and right common carotid artery [CCA], carotid bulb and internal carotid artery) between the rosuvastatin and placebo groups was apparent 6 months after baseline (0.0023 mm/yr and 0.0106 mm/yr, respectively p =0.36). After 12 months CIMT progression rates were significantly different between groups: 0.0032 mm/yr and 0.0133 mm/yr (p=0.049). This divergence grew with further follow-up: − 0.0009 mm/yr and 0.0131 mm/yr after 18 months (p<0.0001), and − 0.0014 mm/yr and 0.0131 mm/yr after 24 months of treatment (p<<178>0.0001). For the individual carotid artery segments, significant differences were seen at 12 months for the mean CIMT of the CCA, and at 18 months for the maximum CIMT of the bulb and the CCA. Conclusion: Aggressive LDL lowering with rosuvastatin exerts its beneficial effect on atherosclerosis during the first year of treatment, which parallels the timing of event rate reduction seen in clinical trials. These findings suggest that, in trials examining the effects of treatment on CIMT progression, a duration of 12 months may be adequate, given sufficient sample size, high precision of measurements, and treatment effect.

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.

Background: This study was carried out to evaluate the effects of folate supplementation on carotid intima-media thickness (CIMT) and metabolic status among patients with metabolic syndrome (MetS). Methods: This randomized, double-blind, placebo-controlled trial was conducted among 60 patients with type 2 diabetes mellitus and coronary heart disease. They were all overweight in the age range 40-85 years. Participants were randomly divided into 2 groups: group A (n = 30) received 5 mg folate supplements and group B (n = 30) received placebo for 12 weeks. Results: Folate supplementation resulted in a significant reduction in maximum levels of left CIMT (-0.05 ± 0.13 vs. +0.02 ± 0.11 mm, p = 0.01) compared with the placebo. Changes in fasting plasma glucose (-2.2 ± 37.5 vs. +30.2 ± 65.8 mg/dl, p = 0.02), serum insulin concentration (-2.0 ± 10.7 vs. +3.0 ± 7.6 µIU/ml, p = 0.04) and homeostasis of assessment-estimated insulin resistance (-0.6 ± 2.3 vs. +0.9 ± 2.3, p = 0.01) in supplemented patients were significantly different from those of patients in the placebo group. Changes in serum triglycerides (p = 0.04), high-density lipoprotein-cholesterol (p = 0.001), high sensitivity C-reactive protein (p = 0.01) and plasma nitric oxide concentrations (p < 0.001) were significantly different between the supplemented patients and placebo group. Conclusions: Overall, 5 mg/day folate supplementation for 12 weeks among patients with MetS had beneficial effects on CIMT and the metabolic status.

Background and Aim: Serum dehydroepiandrosterone sulfate (DHEA-S) is known to be lower in chronic kidney disease (CKD) patients and in those with cardiac disease, and correlates with a poor cardiovascular outcome. This study aimed to assess the correlation between DHEA-S and carotid intima-media thickness (CIMT) as a predictor of cardiovascular disease in hemodialysis (HD) patients. Methods: A total of 88 HD patients were included in this cross-sectional study. They included 53 male (group I) and 35 female patients (group II). In addition to conventional history taking, clinical examination, and routine laboratory investigations, serum DHEA-S and CIMT were measured for all patients. CIMT was measured using B-mode ultrasonography, and the mean of maximum CIMT was recorded. The 2 patient groups were further classified according to the level of DHEA-S. The correlation between serum DHEA-S and CIMT was studied. Results: In male patients, CIMT and age were significantly higher in the group with low DHEA-S level (p = 0.003 and 0.001, respectively), while there was no significant difference in both parameters in females. A higher percentage of HCV-positive patients is present in the male group with low DHEA-S level (p = 0.009). Serum DHEA-S is significantly negatively correlated with CIMT in males (p = 0.003) but not in females, and has a significant negative correlation to age in both genders (p = 0.001 and 0.04, respectively). Conclusion: Endocrinal disturbance representing as lower serum DHEA-S is associated with increased CIMT, which is considered a predictor of cardiovascular disease in male HD patients, although it is largely explained by advancing age.
