Abstract

Objective

This study investigated the association between the plasma marine n-3 polyunsaturated fatty acids (n-3 PUFAs) eicosapentaenoic acid and docosahexaenoic acid and cardiovascular (CV) events and all-cause mortality in patients treated with hemodialysis.

Methods

Prospective multicenter cohort study with 5 years of follow-up. Primary outcome was CV events and secondary outcomes were all-cause mortality and each component of CV events. The sum of plasma eicosapentaenoic acid and docosahexaenoic acid was expressed as marine n-3 PUFAs in weight percentage (wt%). The population was divided into tertiles according to plasma n-3 PUFA levels: lower tertile <5.06 wt%, middle tertile 5.06-6.52 wt%, and upper tertile >6.52 wt%.

Results

In total, 336 patients were included. Median follow-up was 5.05 (5.02-5.07) years. Generally, the lower tertile was associated with a higher risk of CV events. Unadjusted, the middle tertile was associated with a 36% lower risk of CV events [hazard ratio (HR) 0.64 (95% confidence interval (CI) 0.43-0.96)], and the upper tertile was associated with a 34% lower risk of CV events [HR 0.66 (95% CI 0.44-0.98)]. After adjusting for confounders, the middle tertile was associated with a lower risk of CV events [HR 0.60 (95% CI 0.40-0.92)], peripheral arterial disease [HR 0.44 (95% CI 0.22-0.88)], and all-cause mortality [HR 0.61 (95% CI 0.42-0.86)]. A restricted cubic spline showed that the CV risk was higher in patients with levels below the median of 5.7 wt%, indicating a potential threshold effect.

Conclusion

Low plasma marine n-3 PUFA levels were associated with a higher risk of CV events, peripheral arterial disease, and all-cause mortality in patients treated with hemodialysis.

低血浆海洋 N-3 多不饱和脂肪酸与维持性血液透析患者心血管事件风险增加有关。

目的：探讨血液透析（HD）患者血浆n-3多不饱和脂肪酸（n-3 PUFAs）、二十碳五烯酸（EPA）和二十二碳六烯酸（DHA）与心血管（CV）事件和全因死亡率的关系。方法：前瞻性多中心队列研究，随访5年。主要结局是心血管事件，次要结局是全因死亡率和心血管事件的各个组成部分。血浆EPA和DHA的总和以海洋n-3 PUFAs的重量百分比（wt%）表示。根据血浆n-3 PUFA水平将种群分为三类：低三类为6.52 wt%。结果：共纳入336例患者。中位随访时间为5.05（5.02-5.07）年。一般来说，较低的分值与较高的心血管事件风险相关。未经调整，中位数与心血管事件风险降低36%相关[HR 0.64 (95% CI 0.43-0.96)]，中位数与心血管事件风险降低34%相关[HR 0.66 (95% CI 0.44-0.98)]。在调整混杂因素后，中位数与较低的心血管事件风险[HR 0.60 (95% CI 0.40-0.92)]、外周动脉疾病（PAD） [HR 0.44 (95% CI 0.22-0.88)]和全因死亡率[HR 0.61 (95% CI 0.42-0.86)]相关。限制三次样条显示，低于中位数5.7%的患者的CV风险更高，表明存在潜在的阈值效应。结论：低血浆海洋n-3 PUFA水平与HD患者心血管事件、PAD和全因死亡率升高相关。
