    Notes: [Auszug] More than half of the patients with angiographically confirmed premature coronary heart disease (CHD) have a familial lipoprotein disorder1. Familial combined hyperlipidaemia (FCHL) represents the most common genetic dyslipidemia with a prevalence of 1.0–2.0% (refs 2,3). FCHL is estimated to ...

    Notes: Abstract Earlier we reported that allelic variation in the gene coding for apolipoprotein (apoE) is a significant predictor of variation in the risk of coronary heart disease (CHD) death in a longitudinal study of elderly Finnish men. Here we address the question: which of the apoE genotypes confers the risk information in these men, and whether such information persists after other CHD risk factors are considered? We followed two cohorts of elderly Finnish men aged 65 to 84 years, one in Eastern (n = 281) and the other in the Southwestern (n = 344) Finland for 5 years during which 26 (9.3%) of the men from the Eastern cohort and 40 (11.6%) of the men in the Southwestern cohort died from CHD. Baseline high density lipoprotein (HDL) cholesterol and (HDL cholesterol)2 in the Eastern cohort and age, and total and HDL cholesterol and smoking status in the Southwestern cohort were significant predictors of CHD death (P 〈 0.05). The apoE genotypes were significant predictors in the Southwestern cohort at P = 0.02 and in the Eastern cohort at P = 0.18. In multivariable models, information about apoE genotypes improved the prediction at P = 0.10 level of statistical significance in both cohorts. When genotypes were considered separately, the ɛ2/4 combined with the ɛ4/4 in the Eastern cohort (odds ratio = 7.69, 95% CI = 1.67–35.52) and the ɛ3/4 in the Southwestern cohort (odds ratio = 2.44, 95% CI = 1.16– 5.10) had sigificanctly greater odds of CHD death compared to the common ɛ3/3 genotype. We conclude that apoE genotypes confer risk information about CHD death in two cohorts of elderly Finnish men in a longitudinal study, and this information persists after adjustment for other CHD risk factors. Because different genotypes were predictors in these two cohorts, we further conclude that the utility of a particular genotype as a predictor of CHD death in other populations may depend on the distribution of risk factor profiles at baseline, geographically defined environmental exposures, the CHD mortality history, and the evolutionary history of background genotypes in the population considered.

    Notes: Abstract The clinical significances of different components of the multiple metabolic syndrome were studied in a five-year follow-up study of random persons (n = 1,199) of four birth cohorts at ages 65, 75, 80, and 85 years. The subjects were examined clinically and their serum lipids, blood glucose, plasma insulin, blood pressure, and health score were determined. The health score was measured using a visual analogue scale. All subjects were followed for 5 years. Health score, diastolic blood pressure and body mass index declined over age, but serum triglycerides, and blood glucose were similar, whilst serum high density lipoprotein (HDL)-cholesterol increased. Among women fasting plasma insulin was lowest in the age group of 65 years. The associations of components of the multiple metabolic syndrome varied by age. In the age groups of 65 and 75 years high body mass index, plasma insulin, glucose, triglycerides and low HDL-cholesterol were associated with impaired health. In the age group of 85 years high blood pressure, total cholesterol, and HDL-cholesterol were associated with good health. The baseline health score was consistently lower in the decedents than survivors of all age groups, but components of the metabolic syndrome were generally not associated with impaired survival.
