Renal denervation achieves significant and sustained blood pressure reduction

2012-08-27
(Press-News.org) Munich, Germany – August 27 2012: Renal denervation leads to significant and sustained blood pressure reduction for up to 18 months in patients with treatment resistant hypertension, according to research presented at ESC Congress 2012. The new clinical data from the Symplicity HTN-2 randomized clinical trial were presented by principal investigator Dr Murray Esler at the scientific session, associate director of the Baker IDI Heart and Diabetes Institute of Melbourne, Australia and by Prof Böhm for the ESC Press Conference.

Treatment resistant hypertension is blood pressure that remains persistently high despite at least three prescription blood pressure medications, including a diuretic. This condition puts approximately 120 million people worldwide at risk of premature death from kidney disease and cardiovascular events such as stroke, heart attack and heart failure (1). "Treatment resistant hypertension is one of the most challenging forms of hypertension to manage because it does not respond to blood pressure lowering drugs," said Dr Esler.

Renal denervation is a minimally invasive procedure which disrupts both afferent and efferent nerves leading into and out of the kidneys. It uses radio frequency energy emitted by a catheter device inserted into the renal arteries through the groin to treat patients resistant to drug therapy.

The Symplicity HTN-2 trial is an international, multi-center, prospective, randomized, controlled study of the safety and effectiveness of renal denervation with the catheter-based Symplicity™ renal denervation system in patients with treatment resistant hypertension. Patients with treatment resistant hypertension were randomized in a one-to-one ratio to receive renal denervation plus antihypertensive medications or antihypertensive medications alone (control group) at 24 centers in 11 countries.

At baseline, the treatment (n=49 patients) and control (n=52 patients) groups had similar high blood pressures: 178/97 mmHg and 178/98 mmHg, respectively, despite both receiving an average daily regimen of five antihypertensive medications.

Patients in the control arm of the study were offered renal denervation following assessment of blood pressure, which was the trial's primary endpoint, at 6 months post-randomization. Thirty-five patients from the control group with systolic blood pressures ≥ 160 mmHg received denervation at 6 months (this became the crossover group).

The researchers found that renal denervation was safe and effective in both treatment groups up to 18 months post-procedure. Forty-three patients initially randomized to renal denervation were followed for up to 18 months and had an average blood pressure reduction of -32/-12 mmHg from baseline (p END

Renal sympathetic denervation improves physical and mental health in resistant hypertension

2012-08-27
Munich, Germany – August 26 2012: Renal sympathetic denervation improves anxiety, depression, quality of life and stress in patients with resistant hypertension, according to research presented at ESC Congress 2012 by Dr Denise Fischer from Saarland University Hospital. Arterial hypertension is often associated with several psychological comorbidities, such as anxiety and panic disorders, leading to impaired quality of life. Catheter-based renal sympathetic denervation (RDN) is a novel treatment option for patients with resistant hypertension and has been shown to reduce ...

Renal denervation treats resistant hypertension in real world patient populations

2012-08-27
Munich, Germany – August 27 2012: Renal denervation successfully treats patients with resistant hypertension in real world patient populations, according to a study presented at ESC Congress 2012. The findings were presented by Dr Darren Mylotte from France. Transcatheter renal denervation represents a novel therapy for treating patients with treatment resistant hypertension, a condition which greatly increases the risk of myocardial infarction and stroke. "The Symplicity Hypertension I and II studies have suggested that this procedure significantly lowers blood pressure ...

2012-08-27
August 27, 2012 -- In one of the most comprehensive peer-reviewed discussions on cancer vaccines and immunotherapeutics, a Special Focus in the journal Human Vaccines & Immunotherapeutics provides a critical view on cancer vaccines and a discussion on best approaches for the future. From firsthand accounts of principal investigators involved in numerous failed cancer vaccine programs, including Oncophage® and MVAX®, to commentary from world experts in cancer vaccine development, authors in the Special Focus recount the mistakes of the past and provide an critical lens ...

Renal denervation gives better outcomes than drugs in advanced heart failure

2012-08-27
Munich, Germany – August 27 2012: Renal denervation leads to better outcomes than standard drug treatment in patients with advanced heart failure, according to research presented at ESC Congress 2012. The results of the Olomouc I pilot study were presented by Dr Miloš Táborský from the University Hospital Olomouc. Renal denervation does not involve any pharmacological treatment. It is a multiple application of radiofrequency energy using a thin catheter via the femoral artery and a long-term "denervation" of the sympathetic nerves around the renal arteries. "This is done ...

Precise and persistent cell sabotage

2012-08-27
Some of the body's own genetic material, known as small interfering RNA (siRNA), can be packaged then unleashed as a precise and persistent technology to guide cell behavior, researchers at Case Western Reserve University report in the current issue of the journal, Acta Biomaterialia. The research group, led by Eben Alsberg, associate professor in the departments of Biomedical Engineering and Orthopedic Surgery, have been pursuing experiments that seek to catalyze stem cells to grow into, for example, bone and cartilage cells, instead of fat, smooth muscle and other cell ...

Athletic field paint steals spotlight from the grass it covers

2012-08-27
Aug. 27, 2012 – Professional athletic field managers maintain trimmed turfgrass with great precision, carefully painting crisp lines and colorful logos on their grass before each game. While these fields appear to be in perfect health, some field managers have noted deteriorating turfgrass beneath repeated paint applications. New research now suggests why. In a study that appears in the September-October issue of Crop Science, three North Carolina State University researchers found that grasses coated with latex paints show a notable reduction in photosynthesis. In ...

Zebra fish point the way towards new therapies for amyotrophic lateral sclerosis

2012-08-27
Leuven scientists (VIB/KU Leuven) are using zebrafish as a model in their search for genes that play a role in the mechanism of amyotrophic lateral sclerosis (ALS). As a result, they have identified a molecule that could be the target for a future ALS treatment. ALS is a progressive degenerative motor neuron disease for which there currently is no treatment. Their study has been published in the prestigious journal Nature Medicine. Amyotrophic lateral sclerosis or ALS ALS is a progressive paralyzing disease caused by the destruction of the neurons connecting to the muscles. ...

How methane becomes fish food

2012-08-27
Methane is an organic carbon compound containing the fundamental building block of nearly all living material: carbon. It provides an important source of energy and nutrients for bacteria. Methane is produced in oxygen-free environments and is found in abundance at the bottom of lakes. The Brazilian post-doctoral researcher in biology and ecology, Angela Sanseverino, has presented a study that shows methane from lakebeds to be present in fish tissue. The study was carried out in cooperation with, inter alia, David Bastviken, Water and Environmental Studies (WES), Linköping ...

EARTH: Crowdsourcing for quake-monitoring

2012-08-27
Alexandria, VA – Technology is creating a new breed of scientist. I'm talking about citizen scientists – ordinary people and volunteers from all walks of life coming together to help monitor, and possibly mitigate, the next big earthquake through an innovative program called NetQuakes. A play off the popular company Netflix – a movie company that allows users to rent movies through the mail – NetQuakes allows ordinary people to volunteer as a kind of host "family" for one of the program's many blue seismometers. This grassroots movement, an innovative effort between ...
