L-arginine to Reduce Sympathetic Nerve Activity in CKD Patients

Description

Chronic kidney disease (CKD) is associated with a higher risk of cardiovascular disease and death. An overactive sympathetic nervous system in CKD patients is one of the major mechanisms increasing the cardiovascular risks in this patient population. A potential signal driving sympathetic nerve activity (SNA) involves accumulation of the endogenous nitric oxide synthase (NOS) inhibitor asymmetric dimethylarginine (ADMA). ADMA is elevated in CKD and is a strong, independent predictor of future cardiovascular events in these patients. . The goal of this study is to determine whether overcoming the accumulation of endogenous ADMA with acute L-arginine infusion reduces SNA in CKD patients.
