A revolutionary treatment for high blood pressure?
Washington, Apr 2 (PTI) Scientists have developed a "world-first" treatment to lower high blood pressure and the risk of sudden death, a finding they claim could revolutionise treatment options for hypertension around the world.
An international team, led by the Baker IDI Heart and Diabetes Institute in Australia, has developed the "catheter- based treatment" for life threatening high blood pressure and it also reduces the risk of stroke.
According to them, the treatment involves inserting a catheter through the femoral artery of patients suffering from severe and resistant hypertension -- a dangerous form which doesn't always respond adequately to traditional medications.
The procedure, conducted under a local anaesthetic, uses radio energy frequency delivered via catheter to silence sympathetic nerves in renal artery -- the artery delivering blood supply to the kidneys, they said.
This one-off procedure, conducted on both kidneys, has the potential to substantially reduce the premature ill health and mortality attributed to high blood pressure, a university release said.
The scientists have based their findings on a clinical trial involving 50 patients. The subjects who underwent the procedure had on average a reduction in their blood pressure levels of 30mmHg, dramatically reducing their risk of sudden death due to stroke or heart attack, and their blood pressure remains improved one year later. "The study represented the most important advance in hypertension treatment since the development of drug therapies used today. Even with pharmacological interventions, the number of people reaching target blood pressure remains very low," lead scientists Markus Schlaich said.
High blood pressure is a major health burden around the world and is the cause of debilitating health problems and even sudden death. It is estimated that 30-40 per cent of the population suffer from high blood pressure and of that group, about 15 per cent are resistant to traditional therapies.
The findings are published in 'The Lancet' journal.
