Several studies and reviews regarding the supplementation of omega-3 LC-PUFAs have been developed during the last years. Indeed, the evidence states that high doses omega-3 LC-PUFAs produce a small but significant decrease in blood pressure in older and hypertensive subjects. Due to the increasing interest in the benefits of LC-PUFAs, we aimed to evaluate the scientific evidence provided in the past five years (2012-2016) on the effects of the intake of omega-3 LC-PUFAs on cardiovascular risk factors such as inflammation and oxidative stress, through a systematic review in PubMed database. Twenty-eight articles were related to cardiovascular disease (CVD) and are included in this systematic review. The studies included healthy subjects and CVD patients; we included the number of subjects, type of study, type and doses of omega-3 LC-PUFAs, primary outcomes, and results. The use of omega-3 LC-PUFAs for ameliorating CVD risk factors can be recommended. However, the administration of omega-3 does not seem to show any benefit for the management of CVD or associated complications.
近年来，已经有多项关于ω-3 LC-PUFA 补充剂的研究和综述。事实上，有证据表明，高剂量的 ω-3 LC-PUFA 可使老年和高血压患者的血压略有但显著降低。由于人们对 LC-PUFA 的益处越来越感兴趣，我们旨在通过在 PubMed 数据库中进行系统评价，评估过去五年（2012-2016 年）内有关摄入 ω-3 LC-PUFA 对心血管危险因素（如炎症和氧化应激）影响的科学证据。有 28 篇文章与心血管疾病（CVD）相关，并包含在本系统评价中。这些研究包括健康受试者和 CVD 患者；我们纳入了研究对象的数量、研究类型、ω-3 LC-PUFA 的类型和剂量、主要结局和结果。可以推荐使用 ω-3 LC-PUFA 来改善 CVD 的危险因素。然而，ω-3 的使用似乎对 CVD 或相关并发症的管理没有任何益处。
