Endovascular device-based renal denervation lowers ambulatory and office blood pressure significantly more than sham treatment, with an average decrease of 10 mmHg in office BP.
Does endovascular device-based renal denervation reduce ambulatory and office blood pressure in hypertensive patients compared to sham treatment?
This position paper supports renal denervation as an effective and safe third option for hypertension treatment, based on evidence from sham-controlled RCTs showing significant BP reduction.
This ESH Position Paper 2021 with updated proposed recommendations was deemed necessary after the publication of a set of new pivotal sham-controlled randomized clinical trials (RCTs), which provided important information about the efficacy and safety of endovascular device-based renal denervation (RDN) for hypertension treatment. RDN is effective in reducing or interrupting the sympathetic signals to the kidneys and decreasing whole body sympathetic activity. Five independent, fully completed, sham-controlled RCTs provide conclusive evidence that RDN lowers ambulatory and office blood pressure (BP) to a significantly greater extent than sham treatment. BP-lowering efficacy is evident both in patients with and without concomitant antihypertensive medication. The average decrease of 10 mmHg in office BP is estimated to lower the incidence of cardiovascular events by 25-30%, based on meta-analyses of RCTs using pharmacological treatment. Neither peri-procedural, nor short-term or long-term adverse events or safety signals (available up to 3 years) have been observed. Implementing RDN as an innovative third option in the armamentarium of antihypertensive treatment requires a structured process that ensures the appropriate performance of the endovascular RDN procedure and adequate selection of hypertensive patients. The latter should also incorporate patients' perspective and preference that needs to be respected in a shared decision-making process.
Schmieder et al. (Tue,) conducted a review in Hypertension. Endovascular device-based renal denervation (RDN) vs. Sham treatment was evaluated on Ambulatory and office blood pressure. Endovascular device-based renal denervation lowers ambulatory and office blood pressure significantly more than sham treatment, with an average decrease of 10 mmHg in office BP.
