Renal Denervation is a Minimally Invasive Option to Treat Hypertension
Interrupts Sympathetic Neural Activity Between Brain and Kidneys
Efferent sympathetic signals from the CNS to the kidney and afferent sensory feedback from the kidney to the CNS modulate renal function and overall sympathetic activity.

No hubo diferencias significativas en el cambio de PA a los 6 meses
El gran cambio de PA en el grupo de control sugirió que existían causas significativas de variación que no se controlaron en el ensayo
