| Introduction |
|---|
There is clear evidence that chronic kidney disease (CKD) is often characterized by the presence of sympathetic hyperactivity. Importantly, data are accumulating that this sympathetic hyperactivity is indeed important, because it may influence cardiovascular and renal prognosis. Comprehensive reviews have been published elsewhere [1,2]. The purpose of this Editorial Comment is to briefly summarize available knowledge on the pathogenesis of sympathetic hyperactivity and to discuss its clinical relevance, the consequences of this knowledge for the choice of treatment and as yet unresolved issues.
| Pathogenesis |
|---|
Already in the 1970s, increased catecholamine levels, as an index for sympathetic activity, were reported in CKD patients. With the microneurographic technique, true sympathetic nerve activity can be measured, usually as muscle sympathetic nerve activity (MSNA). This MSNA, for instance measured in the peroneal nerve, represents the centrally generated sympathetic nerve activity directed to resistance vasculature. Sympathetic activity is not uniform in all
