N-3 polyunsaturated fatty acids early supplementation improves ultrasound indices of endothelial function, but not through NO inhibitors in patients with acute myocardial infarction: N-3 PUFA supplementation in acute myocardial infarction.
چکیده انگلیسی

SummaryBackground & aimsour aim was to evaluate early initiated one month n-3 polyunsaturated fatty acids (PUFA) supplementation effects on ultrasound indices of endothelial function and serum asymmetric dimethylarginine (ADMA) levels in patients with acute myocardial infarction (AMI).MethodsForty patients with AMI and successful percutaneous coronary intervention (PCI) were recruited into the study and randomized to the study group (group P; n = 20; standard therapy + n-3 PUFA 1g daily) or the control group (group C; n = 20; standard therapy). Ultrasound indices of endothelial function: flow-mediated dilatation (FMD), nitroglycerin-mediated dilatation (NMD) and serum ADMA concentrations (ELISA) were obtained before and after one month (30 ± 1 days) therapy (presented as means ± standard deviations).ResultsThere was a significant difference between both groups in mean delta (baseline/after one month) FMD (P: 8.1 ± 12.6% vs C: −2.2 ± 11.8%; p = 0.02) with no difference in mean delta NMD (P: 3.3 ± 11.9% vs 0.66 ± 14.3%; p = 0.53). We found also a significant increase in mean FMD (7.4 ± 6.4 to 15.5 ± 10.5%; p = 0.02) with a nonsignificant change in mean NMD values (26.9 ± 12.1 to 30.2 ± 14.0%; p = 0.24) after 1-month therapy with n-3 PUFA. FMD and NMD mean values did not change in control patients (FMD: 11.6 ± 6.1% to 9.4 ± 8.0%; p = 0.5 NMD: 25.1 ± 11.4% to 25.8 ± 14.0%; p = 0.84). The comparison of mean delta ADMA values for both groups revealed no differences (P: 6.2 ± 9.7 μmol/l vs C: 3.6 ± 9.5 μmol/l; p = 0.43). Mean serum ADMA concentrations were significantly increased after 1-month therapy in the group P (P: 2.1 ± 1.8 to 8.3 ± 9.7 μmol/l; p = 0.001; C: 4.5 ± 7.1 to 8.1 ± 9.5 μmol/l; p = 0.09). However, there was a nonsignificant difference in mean baseline serum ADMA levels between both groups (P: 2.1 ± 1.8 μmol/l vs C: 4.5 ± 7.1 μmol/l; p = 0.32). There were no significant correlations between FMD, NMD, ADMA levels and demographic, clinical or biochemical parameters.ConclusionsEarly and short-term n-3 PUFA supplementation improved ultrasound indices of endothelial function without affecting serum ADMA levels in patients with AMI and successful primary PCI.
