Abstract | BACKGROUND: OBJECTIVE: METHODS: The population included 212 patients who underwent clinically indicated coronary angiography. The patients were classified with significantly diseased arteries (SDA) if one or more coronary arteries had a stenosis >50% and with minimally diseased arteries (MDA) if there was no significant stenosis (<40%) in any artery. The severity of CAD was expressed by the number of affected vessels. The fatty acid composition of HDL phospholipids was determined by gas liquid chromatography. Multivariate analyses were used to test the independence of associations between the presence and severity of CAD as outcome variables and fatty acid composition of HDL phospholipids. RESULTS: Patients with SDA showed significantly lower levels of linoleic acid (P = .041), eicosapentaenoic acid (EPA) (P = .027), and docosahexaenoic acid (DHA) (P = .026) than patients with MDA in univariate analyses. The association of linoleic acid (odds ratio [OR] .90, P < .05), EPA (OR, 0.41, P < .02), and DHA (OR, 0.48, P < .02) remained statistically significant in the multivariate analyses. The content of EPA (β = -0.23, P < .01) and DHA (β = -0.17, P < .05) remained inversely significantly associated with the severity of CAD. CONCLUSIONS: This study shows that polyunsaturated fatty acids, including EPA and DHA content of HDL particles, are independently associated with the presence and severity of angiographically documented CAD.
