AbstractSmall-dense low-density lipoprotein (SD-LDL) is associated with coronary heart disease risk. Current methods for its quantification are expensive, complex and time-consuming. Plasma was adjusted to a density (D) of 1.044 g/ml in a volume of 0.18 ml and centrifuged in a Beckman Airfuge at 160 000×

Coronary Artery Atherosclerosis

Familial hypercholesterolaemia (FH) is an inborn error of metabolism that leads to accumulation of low-density lipoprotein cholesterol (LDL-C) particles in the blood and premature coronary artery atherosclerosis. This chapter covers the clinical criteria for the diagnosis of FH, the genetics that underpins the condition, cascade testing, premature coronary heart disease, and treatment methods.

Abstract We determined the frequencies of genetic apolipoprotein E isoforms in 570 survivors of myocardial infarction, all with demonstrable coronary heart disease, as compared with 624 healthy persons. In controls, E-4/E-3 heterozygosity was associated with total cholesterol concentrations of 1985 (SD 364) mg/L and low-density lipoprotein (LDL)-cholesterol concentrations of 1306 (SD 332) mg/L. Significantly lower values, 1811 (SD 312) mg/L and 1121 (SD 274) mg/L, respectively, were observed for E-3/E-2 heterozygous persons. In survivors of myocardial infarction, the respective values were significantly higher than in controls, differing between E-4/E-3 and E-3/E-2 heterozygous patients by 233 and 220 mg/L, respectively. Moreover, E-4/E-3 heterozygosity was accompanied by earlier age of myocardial infarction (48.8 +/- 7.4 years) as compared with E-3/E-2 heterozygosity (53.4 +/- 6.9 years) and E-3/E-3 homozygosity (51.2 +/- 7.7 years). Evidently, apolipoprotein E polymorphism can contribute to total and LDL-cholesterol concentrations in serum, thereby affecting risk of coronary heart disease and myocardial infarction.

Background— High consumption of trans fat has been linked to the risk of coronary heart disease (CHD). We assessed the hypothesis that higher trans fatty acid contents in erythrocytes were associated with an elevated risk of CHD in a nested case-control study among US women. Methods and Results— Blood samples were collected from 32 826 participants of the Nurses’ Health Study from 1989 to 1990. During 6 years of follow-up, 166 incident cases of CHD were ascertained and matched with 327 controls. Total trans fatty acid content in erythrocytes was significantly correlated with dietary intake of trans fat (correlation coefficient=0.44, P <0.01) and was associated with increased plasma low-density lipoprotein cholesterol ( P for trend =0.06), decreased plasma high-density lipoprotein cholesterol concentrations ( P for trend <0.01), and increased plasma low-density lipoprotein to high-density lipoprotein ratio ( P for trend <0.01). After adjustment for age, smoking status, and other dietary and lifestyle cardiovascular risk factors, higher total trans fatty acid content in erythrocytes was associated with an elevated risk of CHD. The multivariable relative risks (95% confidence intervals) of CHD from the lowest to highest quartiles of total trans fatty acid content in erythrocytes were 1.0 (reference), 1.6 (0.7 to 3.6), 1.6 (0.7 to 3.4), and 3.3 (1.5 to 7.2) ( P for trend <0.01). The corresponding relative risks were 1.0, 1.1, 1.3, and 3.1 ( P for trend <0.01) for a total of 18:1 trans isomers and 1.0, 1.5, 2.5, and 2.8 ( P for trend <0.01) for a total of 18:2 trans isomers. Conclusions— These biomarker data provide further evidence that high trans fat consumption remains a significant risk factor for CHD after adjustment for covariates.
