A New Method For Treating Stubborn Hypertension.
A tale way to blast away kidney nerves has a smashing effect on lowering blood pressure in tenderness patients whose blood pressure wasn't budging despite fatiguing multiple drugs, Australian researchers report. Although this examination only followed patients for a short time - six months - the authors put faith the approach, which involves delivering radiofrequency animation to the so-called "sympathetic " nerves of the kidney, could have an sense on heart disease and even help lower these patients' endanger of death malewell.icu. The findings were presented Wednesday at the annual joining of the American Heart Association in Chicago and published simultaneously in The Lancet.
The look at was funded by Ardian, the company that makes the catheter cadency mark used in the procedure. "This is an extremely well-connected study, and it has the potential for really revolutionizing the way we deal with treatment-resistant hypertension," said Dr Suzanne Oparil, chairman of the Vascular Biology and Hypertension Program at the University of Alabama at Birmingham. Oparil spoke at a tidings convention Wednesday to announce the findings, though she was not knotty in the study.
Treatment-resistant blood pressure, defined as blood weight 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 untrammelled on four or five drugs and have well and truly refractory hypertension. If it cannot be controlled medically, it carries a leading cardiovascular risk".
This radioablation custom had already successfully prevented hypertension in animal models. According to boning up author Murray Esler, the scheme specifically targets the kidneys' sympathetic nerves. Previous studies have indicated that these nerves are often activated in hominid hypertension a cardiologist and scientist at the Baker IDI Heart and Diabetes Institute in Melbourne, Australia.

New Methods Of Diagnosis Of Stroke
New Methods Of Diagnosis Of Stroke.
The clue to correctly diagnosing when a lawsuit of dizziness is just wooziness or a life-threatening stroke may be surprisingly simple: a pair of goggles that measures leer movement at the bedside in as little as one minute, a unique study contends. "This is the first study demonstrating that we can accurately segregate strokes and non-strokes using this device," said Dr David Newman-Toker, leash author of a paper on the technique that is published in the April climax of the journal Stroke click here. Some 100000 strokes are misdiagnosed as something else each year in the United States, resulting in 20000 to 30000 deaths or savage natural and speech impairments, the researchers said.
As with basics attacks, the key to treating strike and potentially saving a person's life is speed. Magnetic resonance imaging (MRI), the on the qui vive gold standard for assessing stroke, can believe up to six hours to complete and costs $1200, said Newman-Toker, who is an confidant professor of neurology and otolaryngology at Johns Hopkins Hospital in Baltimore. Sometimes hoi polloi don't even get as far as an MRI, and may be sent people's home with a first "mini stroke" that is followed by a caustic second stroke.
The new study findings come with some significant caveats, however. For one thing, the analysis was a small one, involving only 12 patients. "It is unachievable for a small study to uphold 100 percent accuracy," said Dr Daniel Labovitz, conductor of the Stern Stroke Center at Montefiore Medical Center in New York City, who was not confusing with the study. About 4 percent of dizziness cases in the exigency range are caused by stroke.
The other caveat is that the device is not yet approved in the United States for diagnosing stroke. The US Food and Drug Administration only recently gave it blessing for use in assessing balance. It has been present in Europe for that purposefulness for about a year. The device - known as a video-oculography automobile - is a modification of a "head impulse test," which is reach-me-down regularly for people with chronic dizziness and other inner ear-balance disorders.
