Abstract

BACKGROUND/OBJECTIVES: Lower circulating polyunsaturated fatty acids (PUFAs) may induce loss of heart function. We investigated whether lower concentrations of n-3 and n-6 PUFAs were associated with less favourable echocardiographic measures and higher heart rate in older Caucasians, cross-sectionally and after 7 years of follow-up. SUBJECTS/METHODS: We used data from the Hoorn Study, a population-based cohort. Cross-sectional data were available for 621 participants and longitudinal data for 336 participants. Mean age was 68.6 +/- 6.8 years at baseline. We performed linear regression analyses using n-3 and n-6 PUFAs quartiles assayed by gas liquid chromatography with left ventricular ejection fraction (LVEF), left ventricular mass index, left atrial volume index and heart rate. RESULTS: In multivariable analyses (regression coefficient (95% confidence interval)), the lowest eicosapentaenoic acid and docosahexaenoic acid quartiles compared with the highest quartiles were cross-sectionally associated with lower LVEF. Lower eicosapentaenoic acid and docosahexaenoic acid concentrations were associated with higher heart rate: 3.7 b.p.m. (1.5, 6.0; P for trend
