Serum fatty acids, apolipoproteins, selenium and vitamin antioxidants and the risk of death from coronary artery disease.


The independent association of serum concentrations of saturated and polyunsaturated fatty acids, apolipoproteins AI and B, selenium and vitamins A and E with the risk of death from coronary artery disease (CAD) was studied in 92 persons with no previous myocardial infarction, who died from CAD during a 5-year follow-up, and their 92 1-to-1 matched controls. Case-control pairs came from a randomly drawn population sample of approximately 12,000 persons aged 30 to 64 years from 2 provinces of eastern Finland, an area with exceptionally high CAD mortality. Control subjects were matched for sex, age, serum cholesterol, mean arterial pressure, tobacco consumption and history of cardiovascular diseases. The persons who died of CAD had lower serum esterified arachidonic acid concentrations before follow-up than the control subjects (41 vs 48 mg/liter, p = 0.05), and this difference was greater for pairs with no chest pain on effort (36 vs 50 mg/liter, p less than 0.05). The adjusted risk of CAD death in persons with a serum polyunsaturated to saturated (P/S) fatty acid ratio of 0.28 or less (in the lowest tertile) was 3.5-fold (95% confidence interval [CI], 1.5 to 8.2) compared with those with higher serum P/s ratios in a multivariate logistic model and 5.6-fold (95% CI 1.6 to 19.8) for pairs with no chest pain on effort. A low serum apolipoprotein AI concentration (1.25 g/liter or less, in the lowest tertile) was associated with a 2.5-fold (95% CI 1.1 to 5.7) adjusted risk of CAD death among the chest pain-free persons.(ABSTRACT TRUNCATED AT 250 WORDS).
