Renal denervation (RDN) targets the sympathetic nervous system. A pilot study showed proof of principle for reduction of blood pressure in
untreated and uncontrolled hypertensive patients.1 The aim of the SPYRAL HTN-OFF MED Pivotal randomized controlled trial was to evaluate reduction of blood pressure by RDN.
If you missed our online late-breaking presentation on renal denervation from the virtual ACC 2020 WCC, you can watch a replay here. You can also download the complete manuscript of the Pivotal trial results published in The Lancet.

The powered efficacy endpoints for the trial were:
The trial showed clinically significant blood pressure reductions at three months. Specifically, 24-hour systolic ambulatory blood pressure decreased 4.7 mmHg compared to baseline in RDN patients at three months and office systolic blood pressure decreased 9.2 mmHg compared to baseline in RDN patients at three months.2*
The trial also showed that RDN had superior blood pressure reductions compared to control at three months.2† RDN blood pressure reducing benefits are "always on," protecting all day and night, including during the high-risk early hours.
In the trial, there were zero device-or procedure-related major adverse events (MAE) through three months.2 The trial also tracked other MAE:
