Background: : Intake of omega-3 polyunsaturated fatty acids, such as EPA, has been reported to have protective effects on various diseases including ischemic stroke. However, there have been few studies concerning the effect of omega-3 polyunsaturated fatty acids on hemorrhagic stroke. We studied associations of serum levels of EPA with stroke subtypes including primary ICH Methods: We have examined serum EPA and arachidonic acid (AA) levels in routine practice since 2009. To calibrate the EPA values, we calculated EPA/AA ratio. A total of 212 consecutive acute stroke patients and 27 control subjects were included. The patients 40 years old or younger were excluded. Ischemic stroke subtypes were determined based on TOAST criteria. Primary ICH was classified into lobar or nonlobar types, according to the region of the brain in which it occurred. Results: Of all the 157 ischemic stroke patients (female 47, mean age 72.9 years), 62 were classified with cardioembolic stroke (CES), 25 large-artery atherosclerotic (LAA), 22 small-vessel disease (SVD), and 48 other/undetermined causes (O/U). Of all the 55 ICH patients (female 23, mean age 71.0), 34 patients had nonlobar type, and 21 had lobar one. There were no significant intergroup differences in the mean EPA/AA ratio (p=0.525) among CES (EPA/AA= 0.67±0.42), LAA (0.70±0.30), SVD (0.65±0.45), O/U (0.62±0.38), nonlobar ICH (0.51±0.30), lobar ICH (0.64±0.33), and control (0.60±0.42) groups. However, the EPA/AA ratio of the nonlobar ICH group was considerably low. The EPA/AA ratio of the nonlobar ICH group was significantly (p=0.033) lower than that of the whole other groups (0.65±0.39) and significantly (p=0.003) lower than that of the entire ischemic stroke groups (0.67±0.40). Although the significant differences between the nonlobar ICH and the whole ischemic groups were also observed in systolic and diastolic blood pressure (195±37/107±25 mmHg vs 159±35/82±19 mmHg, p<0.001), multiple linear regression analyses showed the association between the EPA/AA and nonlobar ICH was independent from the blood pressure. Conclusions: Although the strongest risk factor for nonlobar ICH is hypertension, low EPA/AA ratio might play a role in the development of nonlobar ICH.

Analysis of influence of high blood pressure over the functional state of kidneys in patients with arterial hypertension and concomitant osteoarthrosis, and overweight with estimation of efficiency of omega of -3-polyunsaturated fatty acids application has been carried out in the review of literature. Hormones and cytokines produced by fatty tissues cooperate at the level of the neuronal systems, causing overactivaty of sympathetic nervous system, increase of blood pressure level in case of excessive weight. Unity of pathogenesis of the investigated pathological processes is shown, for treatment of which omega-3-polyunsaturated fatty acids prescription is rational; that will become a basis of perfection of pathogenetically reasonable and inculcated in medical practice approach for treatment of metabolic disorders.

Epidemiological and clinical studies suggest that consumption of omega (ω-3) polyunsaturated fatty acids (PUFA) contributes to the reduction of cardiovascular mortality through different mechanisms including modulation of cellular metabolic functions, gene expression and beneficial effects on lipid profile or blood pressure. The aim of the study is to review the effects of ω-3 PUFA supplemented as fish oil or blue fish in blood pressure. The analysis of different studies suggests that high doses ω-3 PUFA ( ≥  3 g/day) produces a small but significant decrease in blood pressure, especially systolic blood pressure, in older and hypertensive subjects; however, the evidence is not consistent among different studies. ω-3 polyunsaturated fatty acids consumption might have a place in the control of patients with mild hypertension before starting drug treatment and of those who prefer changes of lifestyles like diet.

AbstractGreater consumption of oily fish, and elevated plasma levels of the long-chain marine-derived omega-3 polyunsaturated fatty acids (PUFAs), docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), have been strongly and consistently associated with a reduced incidence of heart attacks, strokes, cognitive decline, Alzheimer's disease and cancers. Despite international guidelines recommending eating oily fish at least once per week (> 250mg/day DHA and EPA), many people do not eat fish, and only a small minority of the world's population have optimal omega-3-PUFA plasma and tissue levels. Hence, in this project, we studied the bioavailability and blood pressure lowering effects of recently developed alternatives to oily fish, namely chicken-meat and eggs naturally enriched with algae-sourced omega-3-PUFAs.This was a double-blinded, controlled, randomised trial. Using a 2X2 factorial design, 161 healthy participants were randomized to eat at least 3 portions/week of omega-3-PUFA enriched (or control) chicken-meat, and to eat at least 3 omega-3-PUFA enriched (or control) eggs/week, for 6 months.Compared to control foods, eating enriched eggs, enriched chicken-meat and the combination for 6 months, resulted in plasma EPA increments (μg/g) of 3.1[2.8], 8.8[2.9]* & 4.7[2.9], plasma DHA increments (μg/g) of 5.1[3.7], 9.3[3.8]* & 13.1[3.9]*, and omega-3-index (sum of EPA + DHA as a percentage of total fatty acids in erythrocytes, %) increments of 0.9[0.3]*, 0.7[0.4]* & 1.5[0.4]*, respectively. Mean 24-hour ambulatory blood pressure (systolic/diastolic, mmHg) declined with the enriched foods 0.3[1.3]/-0.2[1.0], -0.7[1.4]/-1.4[1.0], & -1.9[1.4]/-2.9[1.0]*, respectively. Data provided as mean difference[SEM], and * denotes p < 0.05.Regular consumption of omega-3-PUFA enriched chicken-meat and eggs resulted in statistically significant and clinically relevant increases in plasma and red cell levels of DHA and EPA. Both plasma and red cell bioavailability were similar to those previously described for oily fish. Furthermore, blood pressure, an important biomarker of cardiovascular health, decreased in those eating the omega-3-PUFA enriched foods. Omega-3-PUFA enriched chicken-meat and eggs offers consumers an attractive additional alternative to eating oily fish. Unlike many lifestyle interventions, long-term large population health benefits are not dependent on willingness of people to make long-lasting dietary changes, but on the widespread availability of a range of inexpensive, commonly eaten, naturally enriched foods.
