Long-term efficacy and safety of renal denervation: an update from registries and randomised trials.

Abstract

Hypertension remains the leading treatable global cause of mortality due to high incidence and poor control rates despite of safe and effective drug therapy.Animal studies do not support functional nerve regrowth after RF-RDN and accordingly clinical evidence verify that RDN leads to durable BP reduction.Renal denervation is safe, as up to 36 months after the procedure, there are no statistically significant difference in procedure-related adverse events, deterioration of renal function and adverse cardiovascular outcomeRenal denervation is efficient in reducing BP in patients with no drug therapy, independently of the number of antihypertensive drugs and phenotype of patient. This sustained and safe reduction in BP observed up to 36 months after RDN could be associated with lower rates of renal and cardiovascular events.
