ACC: Implant Lowers Pressure in Drug-Resistant Patients
Device works by stimulating baroreceptors in the carotid sinus
MONDAY, March 26 (HealthDay News) -- A medical device that stimulates baroreceptors in the carotid sinus significantly reduces blood pressure and heart rate in patients with drug-resistant hypertension, according to a study presented March 25 at the American College of Cardiology's meeting in New Orleans.
Peter de Leeuw, M.D., Ph.D., from University Hospital Maastricht in the Netherlands, and colleagues implanted 26 subjects with stage II hypertension (160 mm Hg systolic or more) who were resistant to at least three anti-hypertension medications with the Rheos Baroreflex Hypertension Therapy System. The system bilaterally activates baroreceptors in the carotid sinus, according to the authors.
The researchers found that after three and six months, there were significant reductions in systolic and diastolic blood pressure as well as heart rate.
"Chronic use of the Rheos Baroreflex Hypertension Therapy System confirms initial observations," de Leeuw and colleagues conclude. "A multicenter, prospective, randomized, blinded study has been initiated to assess long-term benefit."
