Effective with and without medications
The Symplicity blood pressure procedure is effective in the presence and absence of medications.1-3
SPYRAL HTN-ON MED Pilot Study
Results with medications
This study evaluated the effect of the Symplicity blood pressure procedure in the presence of anti-hypertensive drugs.
Three-year follow-up
Clinically significant, safe and sustained and safe blood pressure reductions through three years:
- 18.7 mmHg reduction in 24-hour systolic ambulatory blood pressure (ABPM) for RDN patients vs. baseline (p<0.01)3
- 20.9 mmHg reduction in office systolic blood pressure3
- >80% of patients taking meds achieved SBP <140 mmHg with the Symplicity procedure3
- Zero device or procedural safety events3
- Renal denervation did not negatively affect kidney function3
Long-term safety and efficacy
Prof. Felix Mahfoud presents the SPYRAL HTN-ON MED Pilot Study data at ACC 2022 detailing the long-term safety and efficacy of the Symplicity blood pressure procedure.
24-hour blood pressure lowering effect at three years
In the SPYRAL HTN-ON MED Pilot Study, at three years, blood pressure reductions with the Symplicity blood pressure procedure were present throughout the day and night, including the high-risk zone in the late night and early morning period, which is usually associated with increased risk for stroke and cardiovascular events.3
SPYRAL HTN-OFF MED Pivotal Trial
Results without medications
The powered efficacy endpoints for this trial were:
- Change in 24-hour systolic blood pressure at three months
- Change in office systolic blood pressure at three months
The trial showed clinically signifcant blood pressure reductions at three months. Specifcally, office systolic blood pressure decreased 9.2 mmHg and 24-hour systolic ambulatory blood pressure decreased 4.7 mmHg.†‡2
Always-on blood pressure reduction
The SPYRAL HTN-OFF MED Pivotal Trial showed that the Symplicity blood pressure procedure had superior blood pressure reductions compared to control at three months. Its blood-pressure-reducing benefts are always on, protecting all day and night, including during the high-risk early hours.
