A once promising treatment for severe high blood pressure has proven ineffective in a recent study published in The New England Journal of Medicine.
In the United States, 67 million people have high blood pressure. The treatment, called renal denervation, involves threading a tube through blood vessels into the renal arteries and zapping them with radio-frequency energy.
Although previous case reports and studies found astounding drops in blood pressure through renal denervation, the latest study on the treatment shows no significant difference in drops in blood pressure between a group who received the treatment and a group who only thought they were receiving it.
"I think many people were anticipating there would be some degree of reduction and will be surprised there wasn't anything," said Dr. Deepak L. Bhatt, one of the study's authors. Read the full details here:
