Keeping blood pressure under control is critical. There's a new option for tough cases
About half of U.S. adults have high blood pressure and too few have it under control. Now some patients who’ve tried everything — multiple drugs, diet and exercise — without help are checking out a different option — zapping away some nerves on their kidneys that are fueling their high blood pressure. Using catheters, doctors selectively target the overactive nerves with beams of ultrasound or radiofrequency energy. Two catheter systems hit the U.S. market about a year ago, based on studies showing a modest benefit for hard-to-treat patients, and hospitals now are cautiously beginning to offer it.
