New treatment for resistant hypertension

It is great to read about new research being done to help fight resistant hypertension. This small study had promising results and offers hope for those who take multiple medications and still have high blood pressure.

The study, a world first technique, involves burning off nerves in the kidneys. Scientist say it may revolutionize the treatment of people with high blood pressure.

Why burn off nerves in the kidneys?

Scientists have known that there is a link between the sympathetic nervous system, which serves the kidneys, and high blood pressure. The researchers in this study targeted the nerves embedded in the kidney’s walls which are known to play a major role in the body’s regulation of blood pressure.

Kidney nerve treatment

During the kidney nerve deactivation procedure, a device is inserted into the femoral artery in the groin. The device has a tiny radio emitting tip which is positioned through the arteries to the kidneys.

The tip then emits a signal which burns off nerves in the kidney walls. The process is called renal denervation.

Promising: the study and results

Researchers at St Vincent’s Hospital, Australia studied 45 patients with resistant hypertension. The group had an average blood pressure 177/101mmHg. That is high! About half the group underwent the kidney nerve procedure and were followed for 1 year.

After kidney nerve treatment, the average blood pressure was reduced by:

  • -21/-10 mmHg at 3 months after treatment
  • -24/-11 mmHg at 9 months after treatment
  • -27/-17 mmHg at 12 months after treatment

Among those who did not have the treatment, the average rise in blood pressure was +2/+3 mmHg after 3 months and +26/+17 mmHg after 9 months.

The researchers wrote , “No long-term adverse events resulted from the procedure”. They also added that a large drop in blood pressure was seen in patients who had been taking multiple blood pressure lowering medications without success for a long time. The study results were published in The Lancet.
