Zap nerves for just one hr, be free of high BP forever

London: Believe it or not, just an hour’s operation could now “cure” your high blood pressure, claim scientists, after an international study, published in The Lancet journal, found it to be “safe and effective”.
The treatment uses radio waves to zap nerves near the kidneys that fuel high blood pressure. It is done through a tube pushed into a blood vessel in the groin, much like the angioplasty procedures for opening clogged heart arteries.
In a study of about 100 people, the top number of the blood pressure reading fell an average of 33 points among those who had the treatment. Doctors say that is much better than the less-than-10-point drop that many drugs give. The new treatment damages certain nerves and cause key arteries to permanently relax.
“I am extremely interested in this,” said Elliott Antman, a Brigham and Women’s Hospital cardiologist who is vice chairman of the American Heart Association conference in Chicago. Even if the treatment doesn’t wind up being a cure and is only partly successful, that’s still beneficial because these people are at grave risk of heart attacks, strokes and death, and drugs are not helping them enough now, he said.
The fact the treatment also improves blood-sugar control makes it especially attractive for diabetics with high blood pressure. About 75 million Americans and 1 billion people worldwide have high blood pressure — readings of 140 over 90 or more. Most people need three or four drugs to treat it, and only about one-third are well-controlled on medicines. AGENCIES
