And although the device may effectively reduce blood pressure, the surgery is risky, said Dr. Barry J. Materson, a professor of medicine at the University of Miami Miller School of Medicine.
"In a study published in 2010, there were a number of serious adverse effects related to the surgery and the implanted device and wires," he said, but "no adverse effects are discussed in the present abstract."
Also, the study fails to address the costs associated with the device, Materson said. "This needs to be weighed against the long-term cost of the medications," he added.
Experts note that research presented at meetings is considered preliminary until published in a peer-reviewed journal.
