The electrical measurements on the electrocardiogram can often mislead physicians in diagnosing the heart condition left ventricular hypertrophy, causing other screening tests to be ordered before a definitive conclusion can be made, according to a Henry Ford Hospital study. http://www.physorg.com/news177596514.html Medicine & Health Mon, 16 Nov 2009 12:25:29 EST news177596514 The use of cardiac CT for low-risk chest pain patients in the emergency department, instead of the traditional standard of care (SOC) workup, may reduce a patient`s length of stay and hospital charges, according to a study performed at the University of Washington School of Medicine, Seattle, WA. The SOC workup, which is timely and expensive, consists of a series of cardiac enzyme tests, ECGs and nuclear stress testing. http://www.physorg.com/news166357274.html Medicine & Health Thu, 09 Jul 2009 11:22:10 EST news166357274 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 Cardiac CT can effectively assess coronary artery stenosis, according to a large study performed at Leiden University Medical Center in Leiden, The Netherlands. http://www.physorg.com/news147358007.html Medicine & Health Mon, 01 Dec 2008 12:46:47 EST news147358007 Radiology and cardiovascular researchers from the Medical University of South Carolina in Charleston, S.C., today presented new data that shows the risk of cancer from exposure to radiation during computed tomography for cardiovascular disease has been overstated and that new estimates are several times lower than previously published conclusions. The MUSC researchers presented their findings at the American Heart Association's meeting in New Orleans. http://www.physorg.com/news145536165.html Medicine & Health Mon, 10 Nov 2008 10:42:45 EST news145536165
