Infants born with a severely underdeveloped heart are more likely to survive to their first birthday when treated with a new shunt procedure - yet it may not be the safest surgery long term, according to research presented at the American Heart Association's Scientific Sessions 2009. http://www.physorg.com/news177611670.html Medicine & Health Mon, 16 Nov 2009 17:40:02 EST news177611670 Inflammation still ravages the lungs of some smokers years after they quit the habit. What sparks that smoldering destruction remained a mystery until a consortium of researchers led by Baylor College of Medicine found that certain dendritic cells in the lung - the cells that "present" a foreign antigen or protein to the immune system - provoke production of destructive T-cells that attack a key protein called elastin, leading to death of lung tissue and emphysema. http://www.physorg.com/news175958093.html Medicine & Health Wed, 28 Oct 2009 14:16:16 EST news175958093 Research presented at the 21st annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF), demonstrated an "exceptionally low" rate of complications one year after implantation of transcatheter aortic valve prostheses. http://www.physorg.com/news172761836.html Medicine & Health Mon, 21 Sep 2009 14:40:14 EST news172761836 Patrick Lane, age 74, was plagued by recurring aortic aneurysms ten years ago that threatened his survival. His doctor at the time suggested he contact a leading vascular surgeon at UCLA who was pioneering a new treatment technique for high-risk patients who couldn't receive traditional surgery. http://www.physorg.com/news166884381.html Medicine & Health Wed, 15 Jul 2009 14:00:03 EST news166884381 A test that measures oxygen levels in newborns can detect "critical" congenital heart disease, but there are variables involved with the test that require more study before it is adopted for universal newborn screening, according to a new joint statement from the American Heart Association and the American Academy of Pediatrics. http://www.physorg.com/news166117528.html Medicine & Health Mon, 06 Jul 2009 16:45:53 EST news166117528 Pig heart valves used to replace defective aortic valves in human patients failed much earlier and more often than expected, says a report from cardiac surgeons at Washington University School of Medicine in St. Louis. This is the first report to demonstrate this potential problem, the researchers say. http://www.physorg.com/news165506043.html Medicine & Health Mon, 29 Jun 2009 14:54:26 EST news165506043 Removing a single protein prevents early damage in blood vessels from triggering a later-stage, frequently lethal complication of atherosclerosis, according to research published online today in the journal Nature Medicine. By eliminating the gene for a signaling protein called cyclophilin A (CypA) from a strain of mice, researchers were able to provide complete protection against abdominal aortic aneurysm (AAA). http://www.physorg.com/news161183060.html Medicine & Health Sun, 10 May 2009 14:04:59 EST news161183060 (PhysOrg.com) -- In 1973, Ralph M. Steinman launched a new scientific discipline when he published his discovery of the dendritic cell, an odd-shaped player in the immune system. Since then, dendritic cells have proved to be critical sentinels on the lookout for foreign invaders, involved in early immune responses such as graft rejection, resistance to tumors and autoimmune diseases. Now it appears they need to be considered in research on arterial and heart function, too, according to new experiments to be published February 16 in The Journal of Experimental Medicine. http://www.physorg.com/news154111447.html Medicine & Health Tue, 17 Feb 2009 16:44:42 EST news154111447
