The authors of the study, from Imperial College London, say their findings suggest that the condition could potentially be treated by blocking the molecule that triggers the damage. The research also suggests that bacteria may be playing a part in the disease. http://www.physorg.com/news178820606.html Medicine & Health Mon, 30 Nov 2009 16:50:06 EST news178820606 A team of researchers at the University of California, San Diego and Stanford University has developed a way to simulate blood flow on the computer to optimize surgical designs. It is the basis of a new tool that may help surgeons plan for a life-saving operation called the "Fontan" surgery, which is performed on babies born with severe congenital heart defects. http://www.physorg.com/news178264903.html Physics Tue, 24 Nov 2009 06:20:01 EST news178264903 Heart function significantly improved in children and young adults with single-ventricle congenital heart disease who have had the Fontan operation following treatment with sildenafil, a drug used to treat erectile dysfunction and pulmonary hypertension, say researchers from The Children's Hospital of Philadelphia. http://www.physorg.com/news177772537.html Medicine & Health Wed, 18 Nov 2009 13:40:01 EST news177772537 If you're among the hundreds of thousands of Americans with clogged kidney arteries, you might want to consider trying medicines before rushing into angioplasty to open them up. The pricey procedure is no more effective and carries surprisingly big risks, a study found. http://www.physorg.com/news177186990.html Medicine & Health Wed, 11 Nov 2009 19:00:02 EST news177186990 (AP) -- It seemed like a great idea - doing bypass surgery while the heart is still beating, sparing patients the complications that can come from going on a heart-lung machine. Now the first big test of this method has produced a surprise: Bypass has fewer problems and is more successful done the old way. http://www.physorg.com/news176581115.html Medicine & Health Wed, 04 Nov 2009 18:19:31 EST news176581115 Researchers have fresh insight into an evolutionarily ancient way that cells cope when oxygen levels decline, according to a new study in the October 7th issue of Cell Metabolism. In studies of cells taken from the lining of human pulmonary arteries, they show that a microRNA - a tiny bit of RNA that regulates the activity of particular genes and thus the availability of certain proteins - allows cells to shift their metabolic gears, in a process known as the Pasteur effect. http://www.physorg.com/news174050396.html Medicine & Health Tue, 06 Oct 2009 12:40:01 EST news174050396 For centuries eyes have been seen as windows to the soul.

The findings suggest that a chemical found in vegetables such as broccoli, cabbage and cauliflower, can boost a natural defence mechanism to protect arteries from disease. http://www.physorg.com/news171286193.html Medicine & Health Fri, 04 Sep 2009 12:31:29 EST news171286193 (AP) -- Score another victory for the cheap, cholesterol-lowering wonder drugs known as statins. People getting an artery unclogged or repaired were much less likely to die or have a heart attack afterward if they took preventive doses of the pills before and after their operations, a Dutch study showed. http://www.physorg.com/news171131262.html Medicine & Health Wed, 02 Sep 2009 17:50:03 EST news171131262 (AP) -- Working up a sweat may be even better than angioplasty for some heart patients, experts say. http://www.physorg.com/news170862819.html Medicine & Health Sun, 30 Aug 2009 14:54:06 EST news170862819 A University of Leicester-led study may have uncovered the reason why Beta-blockers are less effective at preventing stroke in older people with high blood pressure, when compared to other drugs for high blood pressure. http://www.physorg.com/news170592408.html Medicine & Health Thu, 27 Aug 2009 11:47:43 EST news170592408 Heart disease patients with previous atherosclerosis (fat deposits in the walls of the arteries) are more likely to die in the hospital and less likely to be treated with recommended therapies, researchers report in Circulation: Journal of the American Heart Association. http://www.physorg.com/news168540891.html Medicine & Health Mon, 03 Aug 2009 18:40:01 EST news168540891 (AP) -- A common method used in heart bypass surgery spares patients pain and problems upfront but seems to raise their risk of dying or suffering a heart attack over the next three years, a worrisome new study finds. The results could have a big impact - about 450,000 bypass operations are done each year in the United States and 70 percent of them use the method at issue. http://www.physorg.com/news166898038.html Medicine & Health Wed, 15 Jul 2009 17:34:37 EST news166898038 (PhysOrg.com) -- A new technology involving the fusion of four different types of images into a 3-D map of a patient's brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from the brain of an Indiana woman. http://www.physorg.com/news166797844.html Medicine & Health Tue, 14 Jul 2009 14:00:04 EST news166797844 If your arteries are clogged and you're facing an angioplasty, your doctor may offer you an unusual choice: wrist or groin? http://www.physorg.com/news163426534.html Medicine & Health Fri, 05 Jun 2009 13:16:02 EST news163426534 People who take cholesterol-lowering drugs called statins after a stroke may be less likely to have another stroke later, according to research published in the May 26, 2009, print issue of Neurology. http://www.physorg.com/news162487678.html Medicine & Health Mon, 25 May 2009 16:28:27 EST news162487678 (PhysOrg.com) -- An international study led by University of Cincinnati (UC) researchers has detected two genetic variations that could provide insight into why intracranial aneurysms develop. http://www.physorg.com/news159803515.html Medicine & Health Fri, 24 Apr 2009 14:52:47 EST news159803515 New studies indicate the three drugs used to treat male impotence also appear to work in females, albeit a little differently, and should give the scientific community pause to take a second look at their potential in the 40 percent of women who report sexual dysfunction, researchers say. http://www.physorg.com/news159189323.html Medicine & Health Fri, 17 Apr 2009 12:16:38 EST news159189323 Researchers at UT Southwestern Medical Center have found that a protein responsible for regulating "bad" cholesterol in the blood works almost exclusively outside cells, providing clues for the development of therapies to block the protein's disruptive actions. http://www.physorg.com/news159170000.html Chemistry Fri, 17 Apr 2009 06:53:48 EST news159170000 Individuals diagnosed with a brain arteriovenous malformation (BAVM) -- an abnormal tangle of arteries and veins -- are at increased risk of vessel rupture and bleeding that can cause permanent brain damage.
