Researchers at Emory University and the Georgia Institute of Technology have developed microscopic polymer beads that can deliver an antioxidant enzyme made naturally by the body into the heart. http://www.physorg.com/news177581687.html Chemistry Mon, 16 Nov 2009 08:15:10 EST news177581687 (PhysOrg.com) -- Scientists prevented age-related changes in the hearts of mice and preserved heart function by suppressing a form of the PI3K gene, in a study reported in Circulation: Journal of the American Heart Association. http://www.physorg.com/news174584415.html Medicine & Health Mon, 12 Oct 2009 17:10:02 EST news174584415 Surgery performed in fetuses predicted to be born with a syndrome causing severely underdeveloped hearts helped some avoid developing the full-blown disorder and improved heart growth and function, researchers reported in Circulation: Journal of the American Heart Association. http://www.physorg.com/news173455732.html Medicine & Health Tue, 29 Sep 2009 15:30:02 EST news173455732 Cardiac experts at Rush University Medical Center are studying a new, minimally invasive procedure to treat leaky heart valves. Instead of open heart surgery, patients will undergo a less complex catheter-based procedure to treat mitral regurgitation, a serious heart disorder where blood leaks backwards toward the lungs with each heart beat. http://www.physorg.com/news173443735.html Medicine & Health Tue, 29 Sep 2009 11:49:47 EST news173443735 The appropriate placement of automated external defibrillators (AEDs) is critical to optimize their use in public places, according to two studies published in Circulation: Journal of the American Heart Association. http://www.physorg.com/news167936124.html Medicine & Health Tue, 28 Jul 2009 00:00:01 EST news167936124 A novel drug that targets a master disease-causing gene can dramatically reduce heart muscle damage after a heart attack and may lead to significantly improved patient outcomes, researchers at the University of New South Wales (UNSW) have shown. http://www.physorg.com/news167651223.html Medicine & Health Fri, 24 Jul 2009 11:30:03 EST news167651223 Researchers in the Heart Institute at Cincinnati Children's Hospital Medical Center have discovered a novel gene responsible for heart muscle disease and chronic heart failure in some children and adults with dilated cardiomyopathy (DCM). http://www.physorg.com/news166724468.html Medicine & Health Mon, 13 Jul 2009 23:30:01 EST news166724468 May 28, 2009 - A new study appearing in Congestive Heart Failure has found that the presence of anemia in patients with chronic heart failure is associated with a significantly increased risk of death. The findings also show that anemia is associated with a poorer degree of left ventricular function and a lower left ventricular ejection fraction, an objective measure of cardiac function. http://www.physorg.com/news162740319.html Medicine & Health Thu, 28 May 2009 14:39:15 EST news162740319 A group of endocrinologists in Sydney have observed that very sick patients tend to have very low levels of Vitamin D. The sicker they are, the lower the levels. http://www.physorg.com/news160305374.html Medicine & Health Thu, 30 Apr 2009 10:16:42 EST news160305374 Can a grape-enriched diet prevent the downhill sequence of heart failure after years of high blood pressure? http://www.physorg.com/news159644910.html Medicine & Health Wed, 22 Apr 2009 18:49:01 EST news159644910 A new study at Wake Forest University School of Medicine reveals that many N.C. high schools are not adequately prepared to handle the immediate medical needs of a student or employee who suffers a sudden cardiac arrest on campus. The findings were used to support a new statewide program to place automated external defibrillators (AEDs) in high schools. http://www.physorg.com/news155815091.html Medicine & Health Mon, 09 Mar 2009 10:58:43 EST news155815091 A heart damaged by heart attack is usually broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity. http://www.physorg.com/news148487985.html Medicine & Health Sun, 14 Dec 2008 14:39:45 EST news148487985 Researchers at the Burnham Institute for Medical Research (Burnham) have shown in both fruit flies and humans that genes involved in embryonic heart development are also integral to adult heart function. The study, led by Rolf Bodmer, Ph.D., was published in Proceedings of National Academy of Sciences. http://www.physorg.com/news147447947.html Medicine & Health Tue, 02 Dec 2008 13:45:47 EST news147447947
