A New Method For Treating Stubborn Hypertension – Part 1 of 3
A New Method For Treating Stubborn Hypertension. A unconventional approach to blast away kidney nerves has a striking effect on lowering blood pressure in enthusiasm patients whose blood pressure wasn’t budging despite trying multiple drugs, Australian researchers report. Although this study only followed patients for a short time – six months – the authors find credible the approach, which involves delivering radiofrequency energy to the so-called “sympathetic ” nerves of the kidney, could have an effect on heart disease and even help lower these patients’ danger 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 study was funded by Ardian, the company that makes the catheter cadency mark used in the procedure. “This is an extremely important study, and it has the potential for really 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 scuttlebutt conference Wednesday to announce the findings, though she was not involved in the study.
Treatment-resistant blood pressure, defined as blood tension 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 uncontrolled on four or five drugs and have truly refractory hypertension. If it cannot be controlled medically, it carries a loaded cardiovascular risk”.
