Patients
in the study who were treated with the Enlightn renal denervation
system saw an average reduction of 28 points in systolic blood pressure,
which is the first number expressed in a reading, after 30 days. At six
months, the 46 patients who received the treatment maintained an
average systolic blood pressure reduction of 26 mmHg points.
The results were presented at the annual meeting of the American Heart Association in Los Angeles.
Patients
enrolled in the study had an average blood pressure of 176/96 mmHg
despite being treated with multiple medications to manage the condition.
No serious side effects were reported, St Jude said.
Normal blood pressure is below 120/80 mmHg. Hypertension, or high blood pressure, is a reading above 140/90 mmHg.
Renal
denervation is a procedure in which a thin, flexible catheter is
threaded through the body to the renal sympathetic nerves near the
kidneys. Radiofrequency energy is delivered to disrupt the nerve
activity, relieving high blood pressure.
Millions of people have hypertension that is resistant to drugs, putting them at risk of heart attacks and stroke.
The new therapy is not yet approved in the United States, but several products are already available in Europe.
Device
makers that have already received approval to sell hypertension devices
in Europe include Medtronic, the front-runner, St Jude, Covidien, ReCor
Medical and Vessix Vascular.READMORE:http://www.geo.tv/GeoDetail.aspx
