8-11-14-eicosatrienoic-acid and Ischemic-Stroke

The susceptibility vessel sign (SVS) on susceptibility-weighted image, a magnetic resonance imaging technique, reveals thrombi as hypointense signals. We aimed to examine the association between polyunsaturated fatty acid (PUFA) levels and the presence of the SVS and its length in cardioembolism due to atrial fibrillation (AF).. Consecutive ischemic stroke patients who met the following inclusion criteria were screened: 1) patients with cardioembolism, defined by Trial of ORG 10172 in Acute Stroke Treatment, secondary to AF; 2) onset to door time within 24 h; 3) availability of magnetic resonance images, including susceptibility-weighted images, obtained at our hospital before performing recanalizing therapy; and 4) availability of PUFA measurements on the day of or the day after the hospital visit. We evaluated whether PUFA levels might be associated with the presence of the SVS and its length.. We retrospectively screened 1720 consecutive ischemic stroke patients, and included 137 patients (95 (69%) male, median age 73 years) who met the inclusion criteria in the analyses. In binomial logistic regression analysis, lower dihomo-γ-linolenic acid (DGLA) level was associated with the presence of SVS (odds ratio 0.545, 95% confidence interval 0.374 to 0.794, p = 0.002). Multiple linear regression analysis revealed a significant negative association between DGLA levels and SVS length (unstandardized coefficient -7.430, 95% confidence interval -13.256 to -1.603, p = 0.013).. Low DGLA level is associated with the presence of SVS and its length in patients with cardioembolism secondary to AF.

Dietary triglycerides influence fatty acid (FA) serum concentrations and weight percentages (wt %), which may be associated with the age of onset of acute ischemic stroke (AIS). We investigated the correlations between serum FA levels and proportions at admission and the age of onset of AIS. We evaluated patients with AIS admitted between 2016 and 2019 within 24 h of AIS onset and calculated the correlation coefficients between their ages, serum FA concentrations, and FA wt % values. Multiple linear regression analysis was performed to identify independent FAs indicating AIS age of onset. Furthermore, we estimated the threshold values of independent FAs for age of onset <60 years using receiver operating characteristic curves by logistic regression. A total of 525 patients (median age: 75 years) met the inclusion criteria. The concentration of dihomo-gamma-linolenic acid (DGLA) and wt % of docosahexaenoic acid (DHA) were significant independent variables for age of onset of AIS, and receiver operating characteristic curves for age of onset <60 years showed thresholds of ≥117.7 µmol/L for DGLA and ≤3.7% for DHA. An increased DGLA concentration and decreased DHA wt % were significantly associated with onset of AIS at a younger age.

Dietary triglycerides influence the serum concentrations of fatty acids (FA) and their weight percentages (wt%), which might be associated with the age of onset of intracerebral hemorrhage (ICH). We investigated the correlation between serum FA levels and proportions at admission, and the age at onset of ICH. We included patients admitted between 2016 and 2019 within 24 h of the onset of ICH, and calculated the correlation coefficients between their age, serum FA concentration, and FA wt%. We performed multiple linear regression analysis to identify individual FAs related to the age at onset of ICH. Furthermore, we estimated the threshold values of FAs that were independently associated with the age at onset of ICH <65 years, using receiver operating characteristic curves by logistic regression. Our inclusion criteria were met by 141 patients (mean age, 67 years). The concentration of dihomo-gamma-linolenic acid (DGLA) and the wt% of eicosapentaenoic acid (EPA) were significant independent variables for the age at onset of ICH. The ROC curves for the age of onset <65 years were ≥108.6 µmol/L for DGLA and ≤1.7% for EPA. Increased DGLA concentration and decreased EPA wt% were significantly associated with young-onset ICH.
