Since the heart is such a delicate and critical organ, clinicians usually opt not to intervene with the dead cells that remain after a heart attack or cardiac disease. "But we think that all heart attacks deserve some kind of treatment because it puts so much stress on the rest of the heart," said Thomas Webster, professor and chair of the Department of Chemical Engineering. Even a square centimeter of dead heart tissue can put significant strain on the rest of the heart, which has to pick up the slack, he said. http://phys.org/news287998232.html Nanotechnology Fri, 17 May 2013 08:50:05 EST news287998232 Despite what Hollywood would have you believe, not all epidemics involve people suffering from zombie-like symptoms--some can only be uncovered through door-to-door epidemiology and advanced mathematics. http://phys.org/news236347408.html Biology Tue, 27 Sep 2011 13:04:08 EST news236347408 Heart disease is a silent killer, but new microchip technology from Rice University is expected to advance the art of diagnosis. http://phys.org/news215676657.html Medicine & Health Mon, 31 Jan 2011 06:11:50 EST news215676657 Certain strains of the food pathogen Listeria are uniquely adapted to infect heart tissues and may put people at a higher risk from serious cardiac disease, according to a new study published in the Journal of Medical Microbiology. Developing new diagnostic tests to identify these potentially fatal strains could protect those most at risk, such as those with heart valve replacements. http://phys.org/news215239249.html Biology Wed, 26 Jan 2011 04:41:05 EST news215239249 Patients who need assistance to breathe through mechanical ventilation may benefit from listening to music, a new review published in The Cochrane Library shows. The researchers found that music listening may relax patients, potentially resulting in fewer complications. http://phys.org/news211002349.html Medicine & Health Wed, 08 Dec 2010 03:46:34 EST news211002349 In an effort to protect children from harmful tobacco smoke exposure, health and medical professionals are pushing for a ban on smoking in public housing in a report appearing in this week's New England Journal of Medicine. http://phys.org/news195996944.html Medicine & Health Thu, 17 Jun 2010 12:50:01 EST news195996944 Researchers at Mount Sinai School of Medicine have developed a new gene therapy that is safe and effective in reversing advanced heart failure. SERCA2a (produced as MYDICAR) is a gene therapy designed to stimulate production of an enzyme that enables the failing heart to pump more effectively. In a Phase II study, SERCA2a injection through a routine minimally invasive cardiac catheterization was safe and showed clinical benefit in treating this patient population and decreasing the severity of heart failure. The data were presented this week at the Heart Failure Congress of the European Society of Cardiology in Berlin. http://phys.org/news194805123.html Medicine & Health Thu, 03 Jun 2010 18:20:02 EST news194805123 Cardiac nuclear imaging and computed tomography angiography (CCTA) still have an important role to play in cardiac disease diagnosis, say experts from the European Society of Cardiology (ESC). http://phys.org/news188579699.html Medicine & Health Tue, 23 Mar 2010 16:15:23 EST news188579699 A new therapy that reduces the risk of mortality and heart failure in patients with mild cardiac disease received a thumb's up this week from an advisory panel to the U.S. Food and Drug Administration. The panel recommended that the cardiac resynchronization therapy defibrillator (CRT-D), tested extensively nationwide under the leadership of cardiologist Arthur Moss, M.D., professor of Medicine at the University of Rochester Medical Center, be approved for use in patients with mild heart failure in the United States. http://phys.org/news188225593.html Medicine & Health Fri, 19 Mar 2010 13:53:40 EST news188225593 Scientists are reporting the first-ever data to show that the enzyme calcineurin is critical in controlling normal development and function of heart cells, and that loss of the protein leads to heart problems and death in genetically modified mice. http://phys.org/news185798488.html Chemistry Fri, 19 Feb 2010 11:10:01 EST news185798488 Investigators in The Research Institute at Nationwide Children's Hospital have identified a link between specific modifications of the dystrophin gene and the age of cardiac disease onset in patients with Becker muscular dystrophy (BMD). This information could help clinicians provide early cardiac intervention for BMD patients based on genetic testing results performed on a blood sample. These findings are a result of analysis of the largest number of BMD patients to date and are published in the December issue of the journal Circulation: Cardiovascular Genetics. http://phys.org/news182621328.html Medicine & Health Wed, 13 Jan 2010 16:20:06 EST news182621328 Cardiac rhythm disorders can result from disturbances in cardiac metabolism. These metabolic changes are tightly linked with specific cardiac electrophysiology (CEP) abnormalities, such as depressed excitability, impaired intra- and extracellular conductivities, wave propagation block, and alteration of conduction velocity, action potential amplitude, and duration. The altered electrophysiology eventually can lead to arrhythmias, fibrillation, and cardiac death; therefore, understanding the spatiotemporal complexity of the relationship between metabolism and electrophysiology is the challenge in developing new approaches for treatment of cardiac diseases. http://phys.org/news175777096.html Medicine & Health Mon, 26 Oct 2009 12:03:07 EST news175777096 (PhysOrg.com) -- People with kidney disease undergo balloon dilation treatment after myocardial infarction less frequently, and therefore have a poorer prognosis.
