Abstract
Dyslipidemia, characterized by abnormal lipid levels in the bloodstream, is a very common and underappreciated chronic disease associated with a significant cardiovascular disease burden. The management landscape for dyslipidemia has historically been static, with a sparse selection of therapeutic options. This article presents a comprehensive review of contemporary approaches to dyslipidemia management, focusing on therapeutic strategies and emerging interventions. We delineate the most current American Heart Association/American College of Cardiology & Canadian Cardiovascular Society guidelines and examine pivotal clinical trials that are shaping the contemporary approach to dyslipidemia management.

Abstract
Cardiovascular diseases (CVD) remain the leading cause of death across the globe, hence, establishing strategies to counteract CVD are imperative to reduce mortality and the burden on health systems. Dietary modification is an effective primary prevention strategy against CVD. Research regarding dietary supplementation has become increasingly popular. This review focuses on the current in vivo, in vitro, and epidemiological studies associated with that of omega-3 polyunsaturated fatty acids (n-3 PUFAs) and polar lipids (PLs) and how they play a role against CVD. Furthermore, this review focuses on the results of several major clinical trials examining n-3 PUFAs regarding both primary and secondary prevention of CVD. Notably, we place a lens on the REDUCE-IT and STRENGTH trials. Finally, supplementation of PLs has recently been suggested as a potential alternative avenue for the reduction of CVD incidence versus neutral forms of n-3 PUFAs. However, the clinical evidence for this argument is currently rather limited. Therefore, we draw on the current literature to suggest future clinical trials for PL supplementation. We conclude that despite conflicting evidence, future human trials must be completed to confirm whether PL supplementation may be more effective than n-3 PUFA supplementation to reduce cardiovascular risk.

Role of natural fatty acids in prophylaxis and treatment of cardiovascular diseases. HERBA POLONICA 2022.

Abstract
Summary
Multiple randomized controlled trials (RCTs) have assessed the effects of supplementation with eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) known as omega-3 polyunsaturated fatty acids (FAs), commonly called fish oils, on the occurrence of cardiovascular diseases. In a living organism, omega-3 FA (EPA and DHA) and omega-6 FA (arachidonic acid [AA]) are also involved in the formation of key regulators of platelet aggregation, vasodilation and inflammation. It is important to know that EPA and DHA act in different ways on membrane structure and lipid metabolism. For this reason, combining DHA with EPA may modify the clinical effects of only EPA treatment. The effects of omega-3 FAs on cardiovascular system remain uncertain. Two recent negative trials of EPA + DHA, STRENGTH and OMEMI, have put the utility of omega-3 FAs in preventing atherosclerotic cardiovascular events under debate. This paper presents the actual knowledge on the role of polyunsaturated acids in cardiovascular diseases.

Abstract
None of the clinical trials of omega-3 fatty acids using combinations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were able to show any effect on cardiovascular outcomes, despite reductions in triglyceride levels. In contrast, the Reduction of Cardiovascular Events With Icosapent Ethyl-Intervention Trial (REDUCE-IT), which employed high-dose (4 g) purified EPA, demonstrated a 25% reduction in atherosclerotic cardiovascular disease-related events compared with placebo (hazard ratio 0.75; 95% confidence interval 0.68-0.83; P < 0.001). Moreover, REDUCE-IT is the first clinical trial using a lipid-lowering agent as adjuvant therapy to a statin to show a significant reduction in cardiovascular mortality. Significant reductions in stroke, need for revascularization, and myocardial infarction were also observed. The pharmacology of EPA is distinct from that of DHA, with a differential effect on membrane structure, lipoprotein oxidation, and the production of downstream metabolites that promote the resolution of inflammation. Attained plasma levels of EPA may be an important determinant of efficacy, with a substudy of REDUCE-IT suggesting that the threshold for clinical benefit of EPA is approximately 100 μg/mL, a level achieved in only a minority of patients in other studies. No similar clinical trials of DHA monotherapy have been conducted, so no such threshold has been established. The results of the REDUCE-IT and the Japan EPA Lipid Intervention Study (JELIS) together affirm the efficacy of EPA therapy for cardiovascular disease risk reduction in certain patient populations.

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27092640. [PMID: 35565990 PMCID: PMC9099931 DOI: 10.3390/molecules27092640] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 04/16/2022] [Accepted: 04/19/2022] [Indexed: 11/29/2022]
Abstract
Edible algae Neopyropia yezoensis is used as “Nori”, its dried sheet product, in Japanese cuisine. Its lipid components reportedly improve hepatic steatosis in obese db/db mice. In this study, we prepared “Nori powder (NP)” and “fermented Nori powder (FNP)” to utilize the functional lipids contained in “Nori” and examined their nutraceutical effects in vivo. Male db/db mice were fed a basal AIN-76 diet, a 10% NP-supplemented diet, or a 10% FNP-supplemented diet for 4 weeks. We detected eicosapentaenoic acid (EPA) present in both NP and FNP in the serum and liver of db/db mice in a dose-dependent manner. The NP diet reduced hepatic triglyceride accumulation (by 58%) in db/db mice by modulating gene expression, which resulted in the inhibition of lipogenic enzyme activity. Additionally, NP intake significantly suppressed the expression of inflammatory genes in the liver and hepatic injury marker levels in the sera (by 26%) of db/db mice. The FNP diet also led to a marked reduction in hepatic triglyceride accumulation (by 50%) and hepatic injury (by 28%) in db/db mice, and the mechanism of these alleviative actions was similar to that of the NP diet. Although the EPA content of FNP was one-third that of NP, metabolomic analysis revealed that bioactive betaine analogs, such as stachydrine, betaine, and carnitine, were detected only in FNP. In conclusion, we suggest that (1) mechanical processing of “Nori” makes its lipid components readily absorbable by the body to exert their lipid-lowering effects, and (2) fermentation of “Nori” produces anti-inflammatory molecules and lipid-lowering molecules, which together with the lipid components, can exert hepatic steatosis-alleviating effects.
