However, currently available immunosuppressant drugs can pose serious health risks, restricting their long-term use. Now, new research findings may lead to the development of immunosuppressant drugs that have fewer adverse side effects. The study, published by Cell Press in the March 13th issue of the journal Molecular Cell, reveals detailed information about how drugs commonly used to prevent transplant rejection interact with their target. http://www.physorg.com/news156084308.html Biology Thu, 12 Mar 2009 13:50:10 EST news156084308 A study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has demonstrated that a new immunohistochemical test is reliable in diagnosing a dangerous arrhythmic heart disease known as arrhythmogenic right ventricular cardiomyopathy (ARVC.) Reported in the March 12 issue of The New England Journal of Medicine (NEJM), the new findings offer the possibility of a highly sensitive and specific means of identifying this life- threatening condition at an early stage, when it can be treated with by implanting a cardiac defibrillator. http://www.physorg.com/news156013932.html Medicine & Health Wed, 11 Mar 2009 18:12:50 EST news156013932 New data published in the March 17, 2009, issue of the Journal of the American College of Cardiology suggest that relatively healthy women with severe depression are at increased risk of cardiac events, including sudden cardiac death (SCD) and fatal coronary heart disease (CHD). Researchers found that much of the relationship between depressive symptoms and cardiac events was mediated by cardiovascular disease risk factors, such as high blood pressure, high cholesterol and smoking. http://www.physorg.com/news155842498.html Medicine & Health Mon, 09 Mar 2009 18:35:38 EST news155842498 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 The new medical subspecialty of Advanced Heart Failure and Transplant Cardiology will lead the way in providing technically advanced yet cost-effective care for patients with heart failure, says a perspective article in the March issue of the Journal of Cardiac Failure, official publication of the Heart Failure Society of America (HFSA) and the Japanese Heart Failure Society, published by Elsevier. http://www.physorg.com/news155473096.html Medicine & Health Thu, 05 Mar 2009 10:59:36 EST news155473096 When young, apparently healthy athletes suddenly collapse, it can be due to hereditary cardiac disease. Researchers at the Heidelberg University Hospital have now discovered a genetic modification that leads to cardiac weakness in an animal model. Just one "false" amino acid can give zebrafish a heart condition. Since the fish have a genetic makeup similar to that of humans, these defects could be critical for humans as well. http://www.physorg.com/news155471734.html Medicine & Health Thu, 05 Mar 2009 10:35:58 EST news155471734 Before flying off the handle the next time someone cuts you off in traffic, consider the latest research from Yale School of Medicine researchers that links changes brought on by anger or other strong emotions to future arrhythmias and sudden cardiac arrests, which are blamed for 400,000 deaths annually. http://www.physorg.com/news154721177.html Medicine & Health Tue, 24 Feb 2009 18:06:49 EST news154721177 New research published in the March 3, 2009, issue of the Journal of the American College of Cardiology finds that anger-induced electrical changes in the heart can predict future arrhythmias in patients with implantable cardioverter-defibrillators (ICDs). http://www.physorg.com/news154632326.html Medicine & Health Mon, 23 Feb 2009 17:26:07 EST news154632326 30 days after a transient ischemic attack, women are 30 percent less likely to have a stroke than men, according to researchers at the University of Alabama at Birmingham (UAB) and Yale University.

It has long been known that heart muscle cells (cardiomyocytes) actively divide and expand in the embryo, but after birth this proliferative capacity is permanently lost. http://www.physorg.com/news154097092.html Biology Tue, 17 Feb 2009 12:45:34 EST news154097092 An enzyme makes the mouse heart prone to chronic cardiac insufficiency - if it is suppressed, the heart remains strong despite increased stress. Cardiologists at the Internal Medicine Clinic at Heidelberg University Hospital in cooperation with scientists at the University of Texas Southwestern Medical Center at Dallas and Göttingen University Hospital have now explained this key mechanism in a mouse model and thus discovered a promising approach for the systematic prevention of chronic cardiac insufficiency. The study has now been published online before print in the prestigious journal Proceedings of the National Academy of Sciences. http://www.physorg.com/news154094280.html Medicine & Health Tue, 17 Feb 2009 11:58:23 EST news154094280 Based on a striking similarity between heart disease and Duchenne muscular dystrophy, researchers at Columbia University Medical Center have discovered that a new class of experimental drugs for heart failure may also help treat the fatal muscular disorder. http://www.physorg.com/news153324060.html Medicine & Health Sun, 08 Feb 2009 14:03:07 EST news153324060 Nearly half of patients with heart failure (HF) have problems with memory and other aspects of cognitive functioning, reports a new study published by Elsevier, in the February issue of Journal of Cardiac Failure . http://www.physorg.com/news153065042.html Medicine & Health Thu, 05 Feb 2009 14:05:44 EST news153065042 At the radiation dose levels used in cardiac imaging exams, such as cardiac CT or nuclear medicine scans, the risk of potentially harmful effects from ionizing radiation are low. However, since the exact level of risk is not known, people without symptoms of heart disease should think twice about seeking, or agreeing to, these types of cardiac studies. This is the conclusion of an advisory committee convened by the American Heart Association's Council on Clinical Cardiology and Council on Cardiovascular Radiology and Intervention. A Mayo Clinic cardiologist led the committee. http://www.physorg.com/news152819843.html Medicine & Health Mon, 02 Feb 2009 17:57:43 EST news152819843 Researchers conducting a large, ongoing study to improve detection and prevention of sudden cardiac death were surprised to discover that a specific heart rhythm abnormality - idiopathic QT interval prolongation - increased risk five-fold among patients with coronary artery disease. http://www.physorg.com/news152816807.html Medicine & Health Mon, 02 Feb 2009 17:07:46 EST news152816807
