New technique to treat hypertension or high blood pressure

As experts say, the nerves near the kidney arteries play a role in the blood pressure system and therefor also influence hypertension. Now it . So it is discovered that when those nerves are brought to silence, the high blood pressure will be positively influenced.

It is believed that hypertension is the main risk factor for premature death while a significant number of world's population suffers from high blood pressure.
While most people know that high blood pressure can lead to heart attack and stroke, probably not many people are aware of the fact that nerves situated in the kidney area have substantial influence in the way blood pressure is determined. Okay that's fine, but the problem is that this nerve system does not function properly in many people.


So here is where the new treatment comes in. This technique, known as RDN, deactivates the nerves in the area of the kidney arteries (blood vessels) resulting in lowering the blood pressure (hypertension) in patients. This method is especially suitable for people who have hypertension but where medications does not give any results in reducing their high blood pressure or at least not enough lowering effect. And it is believed that their are a lot of people belonging to this category.

The treatment technique uses a catheter-based instrument inserted into the renal artery (blood vessel in the groin). The instrument emits controlled high-frequency energy that silences the nerve tissue around the kidneys (radio frequency ablation).
It stops nerve signals and therefore terminates the disrupted mechanism for blood pressure. As the nerves in the kidney area are
close to the groin, this procedure is regarded minimally invasive.
Some of the patients who got this treatment could even stop or reduce medication.

Experts believe that this new treatment might have a large impact in preventing heart attack and stroke in connection to high blood pressure.
One speaks of high blood pressure if the reading is 140/90 mm Hg or higher.
