SPYRAL HTN OFF MED Biologic proof of principle for the efficacy of renal denervation, not powered for statistical significance Clinically significant blood pressure reductions at 3 months In mild to moderate hypertensive patients treated with RDN In the absence of anti-hypertensive medications compared to sham control No major safety events Conclusions Despite a more complete denervation procedure that extended into renal artery branch vessels The results of this feasibility study will inform the design of a larger pivotal trial R.

Take Home Message Confirm the diagnosis of HTN by appropriate BP measurements Sustained strict control of BP (BP<140/90mmHg) is mandatory for all hypertensive patients For those with high CV risk systolic goal BP should be close to 130 mmhg, if tolerated Avoid diastolic BP below 70 mmhg The lower the better (only in some cases) The earlier the better (always) Let s treat the patient and not only the BP number!
