A New Method For Treating Stubborn Hypertension

A New Method For Treating Stubborn Hypertension.
A story chat up to blast away kidney nerves has a striking effect on lowering blood pressure in kindliness patients whose blood pressure wasn't budging despite trying multiple drugs, Australian researchers report. Although this lessons only followed patients for a short time - six months - the authors maintain the approach, which involves delivering radiofrequency energy to the so-called "sympathetic " nerves of the kidney, could have an make on heart disease and even help lower these patients' peril of death. The findings were presented Wednesday at the annual meeting of the American Heart Association in Chicago and published simultaneously in The Lancet.

The mull over was funded by Ardian, the company that makes the catheter logotype used in the procedure. "This is an extremely important study, and it has the potential for extraordinarily revolutionizing the way we deal with treatment-resistant hypertension," said Dr Suzanne Oparil, director of the Vascular Biology and Hypertension Program at the University of Alabama at Birmingham. Oparil spoke at a low-down colloquy Wednesday to announce the findings, though she was not involved in the study.

Treatment-resistant blood pressure, defined as blood squeezing that cannot be controlled on three drugs at full doses, one of which should be a diuretic, afflicts about 15 percent of the hypertensive population. "Many patients are amuck on four or five drugs and have truly refractory hypertension. If it cannot be controlled medically, it carries a huge cardiovascular risk".

This radioablation procedure had already successfully prevented hypertension in zooid models. According to study author Murray Esler, the appliance specifically targets the kidneys' sympathetic nerves. Previous studies have indicated that these nerves are often activated in kindly hypertension a cardiologist and scientist at the Baker IDI Heart and Diabetes Institute in Melbourne, Australia.
