SYMPLICITY HTN-3: failure at 6 months, success at 3 years?

Abstract

In The Lancet, Deepak L Bhatt and colleagues report long-term outcomes of renal artery denervation in patients denervated by single-electrode radiofrequency within the SYMPLICITY HTN-3 study. 1 Bhatt DL Vaduganathan M Kandzari DE et al. Long-term outcomes after catheter-based renal artery denervation for resistant hypertension: final follow-up of the randomised SYMPLICITY HTN-3 Trial. Lancet. 2022; (published online Sept 18.)https://doi.org/10.1016/S0140-6736(22)01787-1 Summary Full Text Full Text PDF Scopus (2) Google Scholar This large sham-controlled trial recruited 535 patients (210 [39%] women and 325 [61%] men; mean age in renal denervation group 57·9 years [SD 10·4]) with treatment-resistant hypertension enrolled in 88 centres in the USA. The trial was expected to provide definitive evidence of the efficacy of renal denervation in patients with treatment-resistant hypertension but did not meet its primary 6-month efficacy endpoint, 2 Bhatt DL Kandzari DE O'Neill WW et al.

From 12 months to 36 months after the procedure, patients who were originally randomly assigned to receive renal artery denervation had larger reductions in blood pressure and better blood pressure control compared with patients who received sham control.
