PHILADELPHIA (CBS) – Local researchers are testing a procedure for people with hard to treat hypertension (read related story).

Hi blood pressure is a huge problem, according to Dr. Nicholas Ruggiero, assistant professor at Thomas Jefferson University.

“High blood pressure is an elevation of blood pressure which, we have learned over time, accounts for an increased risk of stroke, heart attack, kidney damage and, in the U.S. alone, 68 percent of population is aware they have it,” says Dr. Ruggiero.

Only half are well controlled.

He’s testing a procedure using radio frequency ablation on overactive renal nerves to stop them from sending electrical signals to the brain which can raise blood pressure.

Anyone 18 to 80 who takes three medications and still has high blood pressure may be eligible for this minimally invasive therapy.
