Conclusions
In conclusion, we found that short-term ACE inhibitor and ARB administration differentially affects ADMA levels and the arginine-to-ADMA ratio in patients undergoing MHD. These parameters also correlate with markers of inflammation and oxidative stress. While these data suggest that ARB therapy may be a better treatment option for improving non-traditional cardiovascular risk factors in patients on MHD, further studies are required to determine the real therapeutic benefit of these interventions in order to reduce atherosclerotic burden in this patient population.
