After suffering heart attacks, patients often receive stents designed to hold their arteries open. Some of these stents release drugs that are meant to halt tissue growth in arteries, but can have life-threatening side effects such as increasing the likelihood of blood clots and heart attacks. http://www.physorg.com/news179406941.html Medicine & Health Mon, 07 Dec 2009 11:30:01 EST news179406941 Stents that keep weakened and flabby arteries from collapsing have been true life-savers. But after six months, those stents are no longer needed -- once the arteries are strengthened, they become unnecessary. Previously, doctors had no choice but to leave them in place. http://www.physorg.com/news178284711.html Biology Tue, 24 Nov 2009 11:48:28 EST news178284711 The first long-term study following a large number of chest pain patients who are screened with coronary computerized tomographic angiography (CTA) confirms that the test is a safe, effective way to rule out serious cardiovascular disease in patients who come to hospital emergency rooms with chest pain, according to new research from the University of Pennsylvania School of Medicine which will be presented Friday, May 15, 2009 at the Society for Academic Emergency Medicine's annual conference. http://www.physorg.com/news161614587.html Medicine & Health Fri, 15 May 2009 13:56:59 EST news161614587 A study published today in The New England Journal of Medicine (1), analysed the outcomes of 47,967 patients entered into the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) between 2003 and 2006. http://www.physorg.com/news160849737.html Medicine & Health Wed, 06 May 2009 17:29:31 EST news160849737 Drug-eluting stents were safe and superior to bare metal stents in preventing death and heart attacks among 262,700 "real-world" patients enrolled in a nationwide registry of cardiovascular disease, according to researchers from Duke University Medical Center. http://www.physorg.com/news157533919.html Medicine & Health Sun, 29 Mar 2009 08:26:06 EST news157533919 A study published today online in The Lancet (March 13, 2009) presented two year data for the bioabsorbable everolimus coronary stent. Commenting on the results, interventional cardiology specialist, Professor Franz Eberli from the University Hospital Zurich (Switzerland) and official spokesperson for the European Society of Cardiology, said: http://www.physorg.com/news156168819.html Medicine & Health Fri, 13 Mar 2009 13:14:30 EST news156168819 Two years ago, a major study found that many patients who receive delayed treatment for a heart attack do just as well with drugs alone as they do with drugs plus stents to prop open their blocked arteries. Now, further analysis shows that the drug option is cheaper and that there is no meaningful long-term difference in quality of life between the two options. http://www.physorg.com/news154201447.html Medicine & Health Wed, 18 Feb 2009 17:45:05 EST news154201447 Great advances have been made in treating blockages in the arteries of the brain using angioplasty to widen the narrowed artery and a stent to hold the artery open. However, in-stent stenosis, or a re-blockage of the artery within the stent due to scar tissue or blood clots, is estimated to occur in up to 30 percent of patients and can cause a stroke or death. http://www.physorg.com/news153579286.html Medicine & Health Wed, 11 Feb 2009 12:57:41 EST news153579286 Coronary bypass surgery may carry less risk of serious complications if stents coated with a drug that suppresses cell growth are used in the procedure rather than bare-metal stents, UT Southwestern Medical Center researchers and colleagues have found. http://www.physorg.com/news151829798.html Medicine & Health Thu, 22 Jan 2009 06:57:11 EST news151829798 Doctors may be implanting too many artery-opening stents and could improve patient outcomes - and ultimately save lives - if they did more in-depth measurements of blood flow in the vessels to the heart. That's the finding of a study, to be published Jan. 15 in the New England Journal of Medicine, that evaluated the benefits of a new diagnostic tool to measure blood flow and determine whether stenting was the best option. http://www.physorg.com/news151176330.html Medicine & Health Wed, 14 Jan 2009 17:25:30 EST news151176330
