The Individual

Aims Elevated low-density lipoprotein cholesterol (LDL-C) is a risk factor for cardiovascular disease; however, there is uncertainty about the role of total triglycerides and the individual triglyceride-containing lipoprotein sub-fractions. We measured 14 triglyceride-containing lipoprotein sub-fractions using nuclear magnetic resonance and examined associations with coronary heart disease and stroke. Methods Triglyceride-containing sub-fraction measures were available in 11,560 participants from the three UK cohorts free of coronary heart disease and stroke at baseline. Multivariable logistic regression was used to estimate the association of each sub-fraction with coronary heart disease and stroke expressed as the odds ratio per standard deviation increment in the corresponding measure. Results The 14 triglyceride-containing sub-fractions were positively correlated with one another and with total triglycerides, and inversely correlated with high-density lipoprotein cholesterol (HDL-C). Thirteen sub-fractions were positively associated with coronary heart disease (odds ratio in the range 1.12 to 1.22), with the effect estimates for coronary heart disease being comparable in subgroup analysis of participants with and without type 2 diabetes, and were attenuated after adjustment for HDL-C and LDL-C. There was no evidence for a clear association of any triglyceride lipoprotein sub-fraction with stroke. Conclusions Triglyceride sub-fractions are associated with increased risk of coronary heart disease but not stroke, with attenuation of effects on adjustment for HDL-C and LDL-C.

Elevated levels of high-density lipoprotein cholesterol (C-HDL) can explain apparent hypercholesterolemia in some children, and high C-HDL levels may aggregate in families. In this study, 17 kindreds were identified by virtue of hypercholesterolemic proband children whose hypercholesterolemia was accounted for by elevated C-HDL levels. Family lipid and lipoprotein sampling revealed three-generation vertical appearance of elevated C-HDL level in two kindreds, and two-generation vertical appearance in eight additional kindreds. Since C-HDL level is inversely associated with coronary heart disease in adults, it is important to quantitate C-HDL and low-density lipoprotein cholesterol (C-LDL) in hypercholesterolemic children and to identify those with putatively reduced risk (elevated C-HDL level) or increased risk (elevated C-LDL level).

Different Types

In prospective studies, increased levels of cardiolipin-biding antibodies and autoantibodies to oxidized low-density lipoprotein (LDL) have been observed in patients with myocardial infarction (MI). These findings suggest that antiphospholipid antibodies may contribute to the development of MI. The ‘oxidative-modification hypothesis’ in the pathogenesis of atherosclerotic heart disease is based on the oxidation of LDL, its accumulation into arterial wall, and the development of chronic inflammation in the atheroma. Evidence of enhanced lipid peroxidation and its association with antiphospholipid antibodies has been recently reported in SLE patients. There is also epidemiological data showing a remarkably increased risk of MI in SLE. In this review, the role of different types of antiphospholipid antibodies in the development of atherosclerotic heart disease is evaluated with particular attention to their potential pathogenic mechanisms and the possibilities in the prevention of MI associated with antiphospholipid antibodies.

Strategies for disease prevention can have a major impact on people's health. However, major gaps exist in our knowledge with regard to nutritional adequacy, nutrient-disease interactions, nutrient-gene interactions, and effective strategies for implementation of dietary recommendations which have the potential to decrease the disease burden and to contribute to successful aging of the population. Coronary heart disease is one of the major causes of mortality in the world. We have sound evidence that high levels of low-density lipoprotein cholesterol (LDL-C) and low levels of high-density lipoprotein cholesterol (HDL-C) are associated with increased risk of coronary heart disease. Lipoprotein concentrations are associated with environmental variables such as diet and lifestyle, but genetics also play a significant role. We have examined polymorphisms at candidate loci to determine their usefulness as markers for dietary responses. A G/A polymorphism 75 bp upstream from the gene encoding apolipoprotein AI (APOA1) has been described in ~ 30% of the population. Our studies show that this polymorphism is associated with variability in the HDL-C response to dietary fat, specifically to polyunsaturated fatty acids (PUFA) in the diet. Carriers of the A allele respond to increases in dietary PUFA with elevations in HDL-C levels, probably due to altered interactions of transcription factors with the mutated promoter. Therefore carriers of the A allele can potentially decrease their atherogenic risk by consuming high-PUFA diets. Likewise, we have examined the interaction between other dietary habits, such as alcohol drinking, and variability at the APOE locus, and have demonstrated that the classical associations between APOE polymorphism and LDL-C levels are observed primarily in those subjects who consume alcohol. Moreover, we have found a subgroup of the population, APOE4 carriers, for whom drinking alcohol may exert detrimental effects on lipid metabolism. This knowledge will contribute towards the development of more effective personalized dietary recommendations.
