[Denervation denuded].

Area of Science:

• Cardiovascular Medicine
• Nephrology
• Interventional Cardiology

Background:

• Renal denervation aims to treat resistant hypertension by ablating renal sympathetic nerves.
• The procedure reduces sympathetic nervous system activity, potentially lowering blood pressure.
• Early studies suggested efficacy, leading to widespread implementation.

Purpose of the Study:

• To evaluate the effectiveness of renal denervation in patients with resistant hypertension.
• To assess the impact of renal denervation on blood pressure control.
• To highlight the necessity of rigorous device and procedural evaluation.

Main Methods:

• A randomized controlled trial comparing true renal denervation with a sham procedure.
• Inclusion of patients with hypertension resistant to standard drug therapy.
• Assessment of blood pressure changes post-intervention.

Main Results:

• The randomized trial failed to demonstrate a significant reduction in blood pressure following renal denervation compared to the sham procedure.
• This outcome questions the previously assumed efficacy of the technique.
• The study underscores the need for robust clinical evidence.

Conclusions:

• Renal denervation did not show a measurable effect on blood pressure in this randomized trial.
• The findings emphasize the critical need for thorough evaluation of medical interventions and devices.
• Inexperienced specialists should avoid performing renal denervation until further evidence emerges.
