Abstract
BACKGROUND AND AIMS: Although the association between monounsaturated fatty acids (MUFA) and risk factors for heart failure (HF) has been reported, it is unclear whether oleic acid, the predominant MUFA in olive oil, plays a role in the development of HF. Consequently, we sought to examine the relation of plasma phospholipid oleic acid with HF in a male cohort. In a secondary analysis, we examined the relation of the ratio of plasma monounsaturated-to-saturated fatty acids (MUFA: SFA) with HF. METHODS: This prospective nested case-control study was based on 788 incident HF cases and 788 controls from the Physicians' Health Study. Plasma phospholipid fatty acids were measured using gas chromatography and incident HF was self-reported via annual follow-up questionnaires and validated in a subsample using medical records. RESULTS: The mean age was 58.7 years at blood collection. In a conditional logistic regression, multivariable adjusted-odds ratios (95% confidence interval) for HF across consecutive quartiles of oleic acid were 1.0 (reference), 1.10 (0.79-1.54), 1.02 (0.72-1.44), and 1.05 (0.72-1.54). For MUFA:SFA ratio, corresponding odds ratios (95% CI) for HF were 1.0 (ref), 1.12 (0.80-1.58), 1.19 (0.84-1.68), and 0.97 (0.66-1.42). CONCLUSIONS: Our data do not lend support to an association between plasma phospholipid oleic acid or MUFA: SFA ratio and the risk of HF. These results warrant confirmation in the general population including women and other ethnic groups.
