HealthDay (3/29, Salamon) reported that "a technique that interrupts nerve signals between the kidneys and brain dropped blood pressure to normal levels in 39 percent of patients with drug-resistant hypertension, according to a small new study" presented at the Society of Interventional Radiology's annual scientific meeting. For the study, carried out "at 24 international sites, 106 patients with uncontrolled high blood pressure (hypertension) randomly received either oral medication or renal denervation treatment, a procedure that uses a catheter-based probe emitting high-frequency energy near the renal artery to deactivate nearby nerves." Researchers found that, "six months later, the patients who received the nerve block procedure had experienced an average systolic blood pressure drop of 32 mm Hg and a diastolic blood pressure drop of 12 mm Hg."
