High-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) are strong predictors of atherosclerosis. Statin-induced changes in the ratio of LDL-C to HDL-C (LDL-C/HDL-C) predicted atherosclerosis progression better than LDL-C or HDL-C alone. However, the best predictor of subclinical atherosclerosis remains unknown. Our objective was to investigate this issue by measuring changes in carotid intima-media thickness (IMT). A total of 1,920 subjects received health examinations in 1999, and were followed up in 2007. Changes in IMT (follow-up IMT/baselineIMT×100) were measured by ultrasonography. Our results showed that changes in IMT after eight years were significantly related to HDL-C (inversely,P<0.05) and to LDL-C/HDL-C ratio (P<0.05). When the LDL-C/HDL-C ratios were divided into quartiles, analysis of covariance showed that increases in the ratio were related to IMT progression (P<0.05). This prospective study demonstrated the LDL-C/HDL-C ratio is a better predictor of IMT progression than HDL-C or LDL-C alone.

Atherosclerotic Changes

Objective. The purpose of this prospective study was to ascertain if lipid profile parameters could serve as predictors of carotid intima-media thickness (CIMT), which, when combined, may improve the sensitivity of sonographic CIMT measurement in the diagnosis of subclinical atherosclerotic changes. Methods. The lipid profiles and CIMT of 181 subjects without cardiovascular risk factors were measured at the internal, external, common, and bulbar segments. Results. The mean CIMT values obtained were 0.620 ± 0.055 cm for men and 0.575 ± 0.051 cm for women, and the η2 values (η2 < 0.04) were used as a measure of association. Across all segments of both carotid arteries, lipid profiles were significantly and moderately associated with but not predictive of CIMT (fasting blood sugar, total cholesterol, and low-density lipoprotein: η2 = 0.99–0.24). Conclusions. Although lipid profiles were moderately associated with CIMT, they are not significant predictors; hence, combining them with CIMT does not improve the diagnostic sensitivity of sonography in atherosclerosis screening.

Atorvastatin Therapy

Carotid intima-media thickness (cIMT) has been proposed as an early marker of subclinical atherosclerosis in high risk children. Children with heterozygous familial hypercholesterolemia have greater cIMT than matched healthy controls or their unaffected siblings. Statin therapy may delay the progression of cIMT, although long-term studies in children are scarce. We evaluated the effect of atorvastatin treatment on cIMT in children with dyslipidemia. We studied 81 children/adolescents, 27 with severe dyslipidemia (low-density lipoprotein cholesterol [LDL-C] ≥190 mg/dL) and 54 sex- and age-matched healthy controls; LDL-C ≤ 130 mg/dL and lipoprotein (a), Lp(a), ≤30 mg/dL. In the children with dyslipidemia, cIMT was measured twice, before and on treatment (18.2 ± 7.7 months). Anthropometric data, a full lipid profile, liver, kidney, and thyroid function were evaluated. Males with dyslipidemia had a greater cIMT than male controls after adjustment for other factors ( P = .049). In addition, a nonstatistically significant decrease in cIMT was observed after treatment ( P = .261). Treatment with atorvastatin resulted in a significantly improved lipid profile. Females with dyslipidemia had a significantly thinner cIMT than males. Children with normal and high Lp(a) levels had similar cIMT values. In conclusion, treatment with atorvastatin had a beneficial effect on the lipid profile and cIMT progression in children with severe dyslipidemia.

Overweight Or Obesity

Background Whether long‐term exposure to overweight or obesity from early life to adulthood has a detrimental influence on health outcomes is unknown. We aimed to investigate whether duration of overweight or obesity from youth to adulthood is associated with adult cardiometabolic risk. Methods and Results A population‐based cohort study was performed of 1268 youths, aged 3 to 18 years, with follow‐ups at 3, 6, 9, 12, 21, 27, and 31 years. Duration of overweight or obesity over 31‐year follow‐up was calculated. Adulthood outcomes included type 2 diabetes mellitus, impaired fasting glucose, high insulin levels, high carotid intima‐media thickness, hypertension, low high‐density lipoprotein cholesterol, high low‐density lipoprotein cholesterol and triglycerides, arterial pulse wave velocity, carotid artery compliance, Young elastic modulus, and stiffness index. Rates of overweight/obesity were 7.9% at baseline and 55.9% after 31 years. After adjustment for confounders, longer duration of overweight or obesity was associated with increased risk of all outcomes (relative risk ranged from 1.45–9.06 for type 2 diabetes mellitus, impaired fasting glucose, carotid intima‐media thickness, hypertension, high‐density lipoprotein cholesterol, low‐density lipoprotein cholesterol, and triglycerides; β from 0.370–0.543 m/s for pulse wave velocity; –0.193 to –0.237 %/10 mm Hg for carotid artery compliance; 52.1–136.8 mm Hg·mm for Young elastic modulus; and 0.554–0.882 for stiffness index). When body mass index was further adjusted, these associations disappeared or were substantially reduced. Detrimental associations of adult body mass index with all outcomes were robust to adjustment for confounders and duration of overweight or obesity. Conclusions Overweight or obesity in adulthood rather than childhood appears to be more important for adult cardiometabolic health.

Hypercholesterolemia is a major cause of atherosclerosis development and premature cardiovascular disease (CVD). It leads to inflammation, which further accelerates atherosclerosis progression. Familial hypercholesterolemia (FH) is an autosomal dominant disorder characterized by elevated serum LDL-c from birth, due to a disease-causing variant in one of the causative genes (LDLR, APOB, PCSK9). In polygenic hypercholesterolemia (PH), the disease-causing genetic variant is absent; it is likely the cumulative result of multiple single nucleotide polymorphisms in LDL metabolism-related genes and other factors, such as lifestyle and environment. In high risk groups, such as patients with FH, an effective primary prevention of CVD must begin in childhood. High-sensitivity C-reactive protein (hsCRP) and carotid intima media thickness (cIMT) are two potential minimally invasive correlates of inflammation and subclinical atherosclerosis progression. hsCRP and cIMT have been shown to be significantly increased in patients with FH and PH relative to healthy controls, with some studies yielding conflicting results. In this review, we aim to summarize current knowledge and recent findings regarding the applicability of hsCRP and cIMT as markers of low-grade inflammation and subclinical atherosclerosis, focusing especially on children and adolescents with hypercholesterolemia.
