چکیده انگلیسی

Background and purposeBrachial-ankle pulse wave velocity (baPWV) and ratio of plasma eicosapentaenoic acid to arachidonic acid (EPA/AA ratio) are surrogate markers for coronary artery disease (CAD). We aimed to evaluate the effects of a fish-based diet and administration of EPA on baPWV and plasma EPA/AA ratio.Methods and resultsThe changes in baPWV and plasma EPA/AA ratio were compared before and after a 6-month fish-based diet in 191 patients with cardiovascular risk factors. A fish-based diet resulted in significant increment of plasma EPA/AA ratio (0.40 ± 0.18 vs. 0.49 ± 0.27, p < 0.001), with baPWV remaining unchanged. Multivariate analysis revealed that systolic blood pressure (SBP) (6-month SBP-baseline SBP) and CAD were positively associated with increased baPWV (CAD: odds ratio = 2.040, p = 0.0436, SPB: odds ratio = 1.056, p = 0.0003). When the patients were divided into three groups: CAD, low-risk, and high-risk with no prior history of CAD according to the number of risk factors at baseline, comparison among the three groups disclosed an inter-group difference in the magnitude of change in baPWV (low-risk: −35 ± 164 cm/s, high-risk: −14 ± 190 cm/s, CAD: 39 ± 164 cm/s, p = 0.0071 for trend). In 191 patients who had received a 6-month fish-based diet, 21 patients (primarily CAD patients) sequentially received high purity EPA (1800 mg/day) for 6 months. It resulted in marked increment of plasma EPA/AA ratio (0.65 ± 0.57 vs. 1.19 ± 0.46, p < 0.001), accompanied by significant reduction in baPWV (1968 ± 344 cm/s vs. 1829 ± 344 cm/s, p = 0.0061). There was a significant negative correlation between changes in baPWV and changes in plasma EPA/AA ratio in patients with a fish-based diet and sequential administration of EPA (r = −0.446, p = 0.017).ConclusionA fish-based diet was effective against increased baPWV only in low-risk patients, with slight increment of plasma EPA/AA. In high-risk patients and CAD patients, administration of EPA for preventing progression of baPWV endorsed the validity of high purity EPA administration recommended in the current guidelines.
