In one of the few studies of the long-term effects of medication in the treatment of pulmonary arterial hypertension (PAH) disease, a team of researchers found the health and exercise capacity of PAH patients improved after two years of treatment with ambrisentan, according to a study published in the current edition of the Journal of the American College of Cardiology. http://www.physorg.com/news177693087.html Medicine & Health Tue, 17 Nov 2009 15:13:37 EST news177693087 (PhysOrg.com) -- A drug that raises levels of 'good' cholesterol, when taken in addition to standard statin therapy to lower 'bad' cholesterol, can reduce the furring up of arteries in patients with established heart disease, an Oxford University study has shown. http://www.physorg.com/news176575852.html Medicine & Health Wed, 04 Nov 2009 16:51:20 EST news176575852 (PhysOrg.com) -- Children born with certain heart defects have impaired blood flow from the right ventricle to the pulmonary artery leading to the lungs, requiring implanted devices (known as right-ventricular outflow tract conduits) to maintain the flow. However, these conduits fail over time, and children typically face multiple open-heart operations during their lives to reopen the passage. http://www.physorg.com/news176409450.html Medicine & Health Mon, 02 Nov 2009 19:10:01 EST news176409450 Researchers at St. Michael's Hospital have developed the first mathematical model in cardiology and emergency medicine to more quickly and reliably diagnose acute heart failure (AHF) in emergency room patients. Research findings published in the Journal of the American College of Cardiology, have been shown to help physicians diagnose AHF with greater accuracy. http://www.physorg.com/news174820143.html Medicine & Health Thu, 15 Oct 2009 10:20:01 EST news174820143 (PhysOrg.com) -- Common genetic mutations may help explain why some people develop side effects that lead to discontinuing the use of cholesterol-lowering statins. Duke University Medical Center researchers who identified the mutations say they might be used to help doctors match a medication with their patient's genetic makeup. http://www.physorg.com/news174649166.html Medicine & Health Tue, 13 Oct 2009 11:10:15 EST news174649166 Patients who received refurbished pacemakers donated from Detroit area funeral homes survived without complications from the devices, according to a case series reported by the University of Michigan Cardiovascular Center. http://www.physorg.com/news174285882.html Medicine & Health Fri, 09 Oct 2009 06:00:01 EST news174285882 A team of researchers led by Massachusetts General Hospital (MGH) radiologists has developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas of myocardial ischemia - restricted blood flow to heart muscle tissue - giving a better indication of clinically significant coronary artery disease. Their report appears in the September 15 issue of the Journal of the American College of Cardiology. http://www.physorg.com/news172230356.html Medicine & Health Tue, 15 Sep 2009 11:00:02 EST news172230356 A University of Leicester-led study may have uncovered the reason why Beta-blockers are less effective at preventing stroke in older people with high blood pressure, when compared to other drugs for high blood pressure. http://www.physorg.com/news170592408.html Medicine & Health Thu, 27 Aug 2009 11:47:43 EST news170592408 There is mounting evidence that omega-3 fatty acids from fish or fish oil supplements not only help prevent cardiovascular diseases in healthy individuals, but also reduce the incidence of cardiac events and mortality in patients with existing heart disease. A new study, published in the August 11, 2009, issue of the Journal of the American College of Cardiology, extensively reviews data from a broad range of studies in tens of thousands of patients and sets forth suggested daily targets for omega-3 consumption. http://www.physorg.com/news168539596.html Medicine & Health Mon, 03 Aug 2009 20:50:01 EST news168539596 Compared with patients with moderately controlled glucose levels, diabetic patients who have heart failure and either too high or too low glucose levels may be at increased risk of death, said researchers at Baylor College of Medicine in a report published in the current issue of Journal of the American College of Cardiology. http://www.physorg.com/news167330402.html Medicine & Health Mon, 20 Jul 2009 17:50:01 EST news167330402 Researchers in the Heart Institute at Cincinnati Children's Hospital Medical Center have discovered a novel gene responsible for heart muscle disease and chronic heart failure in some children and adults with dilated cardiomyopathy (DCM). http://www.physorg.com/news166724468.html Medicine & Health Mon, 13 Jul 2009 23:30:01 EST news166724468 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 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 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 Introduced in the 1960s, oral contraceptives have been used by about 80 percent of women in the United States at some point in their lives. For women without pre-existing risks for heart disease, the early formulations were generally safe, and the newer ones appear to be even safer, but all the risks and benefits are yet to be established, especially as women's lifestyles change and new forms of contraceptives become available, according to specialists in women's heart disease at Cedars-Sinai Medical Center. http://www.physorg.com/news151151902.html Medicine & Health Wed, 14 Jan 2009 10:38:22 EST news151151902
