| Abstrakt: | Objectives: Dilated cardiomyopathy is the most prevalent type of cardiomyopathy in children, which results in congestive heart failure and causes significant morbidity and mortality. This study, aims to investigate the effect of supplementation with omega-3 polyunsaturated fatty acids (n-3 PUFA) on heart function and oxidative stress biomarkers in these patients. Methods: The present research was a case-control study on pediatric patients with dilated cardiomyopathy, who received n-3 PUFA and anti-failure therapy for 6 months (group 1, n = 6), or anti-failure therapy alone for 6 months (group 2, n = 6), as well as age matched normal individuals (group 3, n = 6), and evaluated the cardiac function and biomarkers of oxidative stress. Results: Echocardiographic parameters, such as left ventricular ejection fraction, shortening fraction, tissue Doppler Ea and Aa waves of lateral annulus of tricuspid valve, and Ea and S wave of septum, were significantly improved in group 1 after n-3 PUFA compared to pre- treatment status, while they were not changed after treatment in group 2. Antioxidant enzymes, including catalase and glutathione peroxidase activities in erythrocytes were slightly decreased, while plasma 8-iso-prostaglandin F2ct concentrations were somewhat increased in group 1 compared to groups 2 and 3, however these changes were not statistically significant. Total antioxidant capacity of plasma was similar in all 3 groups. Conclusions: The results indicate that some echocardiographic parameters were significantly improved in patients receiving omega-3 fish oil. However, omega-3 had no significant effect on oxidative stress biomarkers. [ABSTRACT FROM AUTHOR] |
