Increased levels of asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA) and low plasma level of L-arginine (L-ARG) are all conditions likely to decrease nitric oxide (NO) production. Aim of this study is to evaluate ADMA, SDMA, and L-ARG plasmatic levels before and after physical exercise in patients with coronary artery disease (CAD). We studied 30 patient with mean age 52 ± 4.5 years. After inclusion in the study, before the execution of physical exercise, heparinized blood sample was drawn from an indwelling arterial line for determination of ADMA, L-ARG and SDMA (baseline values). Subsequently a blood sample was drawn after the physical exercise. The mean plasma concentrations of ADMA (0.68 ± 0.06 vs 0.48 ± 0.05 µmol/L) and SDMA (0.45 ± 0.03 vs 0.30 ± 0.03 µmol/L) were significantly lower after physical exercise in comparison to baseline value, while L-ARG mean levels were increased (44.20 ± 10.5 vs 74.13 ± 11.2 µmol/L). Physical exercise has a beneficial effect by reducing plasmatic ADMA and SDMA levels, and increasing L-ARG substrate for endothelial NO.
