Ardian, a medical device company based in Mountain View, California, has developed a device and a surgical procedure that can lower blood pressure in patients who have difficult-to-treat hypertension. The surgery involves the destruction of nerves in the renal arteries.
A study was recently published in The Lancet titled, "Renal sympathetic denervation in patients with treatment-resistant hypertension (The Symplicity HTN-2 Trial): a randomised controlled trial." Here's what the researchers found:
At 6 months, 41 (84%) of 49 patients who underwent renal denervation had a reduction in systolic blood pressure of 10 mm Hg or more, compared with 18 (35%) of 51 controls (p<0·0001).It will be very interesting to see where this goes.
