I read with great interest the article by Khan et al., published online in advance
of print in the Canadian Journal of Cardiology.
1
This article presents a position statement on renal denervation by the Canadian Hypertension
Education Program, and stated that “the limited trial data published to date have
shown clinically significant reduction in BP (blood pressure).” However, the authors
did not cite references with different results. For example, in 2012, Brinkmann and
colleagues showed that renal denervation (n = 12) did not decrease office systolic
blood pressure (157 mm Hg vs 157 mm Hg, for baseline and 3-6 months after the procedure).

Shortly after the acceptance of this position paper, Drs Fadl Elmula and Hart separately
reported that renal denervation non-significantly decreased office systolic blood
pressure by 7-8 mm Hg six months after the procedure (P > 0.05 for both studies).

- PreviewRenal denervation is a novel catheter-based, percutaneous procedure using radiofrequency energy to ablate nerves within the renal arteries. This procedure might help to significantly lower blood pressure (BP) in patients with resistant hypertension, defined as BP > 140/90 mm Hg (> 130/80 mm Hg for those with diabetes) despite use of ≥ 3 optimally dosed antihypertensive agents, ideally including 1 diuretic agent. The Canadian Hypertension Education Program Recommendations Task Force reviewed the current evidence on safety and efficacy of this procedure.
