Physicians should "throttle back" from routinely ordering stress tests and prescribing beta blockers to patients before non-cardiac surgeries, according to a report by the University of Michigan released online this week. http://www.physorg.com/news179002118.html Medicine & Health Wed, 02 Dec 2009 19:20:11 EST news179002118 Providing free medications to people after heart attack could add years to patients' lives at a relatively low cost for provincial governments, according to a new study by researchers at St. Michael's Hospital in Toronto. http://www.physorg.com/news178811123.html Medicine & Health Mon, 30 Nov 2009 14:10:02 EST news178811123 In a new study, researchers report that a class of heart medications called beta-blockers can have a helpful, or harmful, effect on the heart, depending on their molecular activity. http://www.physorg.com/news177941049.html Medicine & Health Fri, 20 Nov 2009 12:20:04 EST news177941049 Predicting the side-effects of a drug is not simple task. The human body has more than 1,500 molecules that are known to be involved in various diseases, and often a drug designed to hit one of these targets will also hit others that have similar structures, causing unintended consequences. http://www.physorg.com/news177183252.html Medicine & Health Wed, 11 Nov 2009 17:37:10 EST news177183252 Cardiac complications around the time of noncardiac surgery are relatively common and can be serious. The American College of Cardiology (ACC) and the American Heart Association (AHA) today release a Focused Update to the Practice Guidelines based on new clinical trial data that summarizes and sheds light on the risks and benefits of using beta blockers to reduce cardiac events during noncardiac surgeries, and provides specific recommendations about which patients will likely benefit and in which patients there is not enough evidence to recommend their use. http://www.physorg.com/news176395023.html Medicine & Health Mon, 02 Nov 2009 14:50:11 EST news176395023 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 Thinking "outside the medicine cabinet" is paying off in Australia, where a doctor-pharmacist partnership is reducing hospitalizations for heart failure - one of the most expensive conditions to treat - researchers report in Circulation: Heart Failure. http://www.physorg.com/news169832378.html Medicine & Health Tue, 18 Aug 2009 17:40:02 EST news169832378 Heart disease patients with previous atherosclerosis (fat deposits in the walls of the arteries) are more likely to die in the hospital and less likely to be treated with recommended therapies, researchers report in Circulation: Journal of the American Heart Association. http://www.physorg.com/news168540891.html Medicine & Health Mon, 03 Aug 2009 18:40:01 EST news168540891 Chronic kidney disease (CKD) can significantly lessen patients' quality of life, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). Certain types of patients -women, diabetics, and those with a history of heart complications -are most affected. These findings indicate that medical care for CKD patients should include strategies to lessen the negative impact of CKD on quality of life. http://www.physorg.com/news168198229.html Medicine & Health Thu, 30 Jul 2009 20:50:01 EST news168198229 When migraine strikes, because of severe pain, often accompanied by nausea and sensitivity to light and sound, sufferers are effectively disabled for up to 72 hours. Since they are forced to stop what they are doing until the pain and other symptoms subside, migraine causes a significant loss in productivity at work and the personal lives of those affected. Migraineurs - especially the 25% of migraineurs who experience more than three migraine attacks per month - are looking to drug developers to provide new drugs to prevent migraine attacks before they start. In the U.S. alone, approximately 30 million people suffer from migraines and the cost to employers has been estimated at $13 billion annually in lost productivity. Currently, several types of drugs, like generic beta blockers, calcium channel blockers, tricyclic antidepressants and anti-epileptic drugs, some of which are used off-label, are given to prevent migraines. However, many patients have only a partial response to these products, many of which have troubling side effects. Nevertheless, many migraine patients use existing drugs, illustrating how badly new drugs are needed. http://www.physorg.com/news160212951.html Medicine & Health Wed, 29 Apr 2009 08:36:22 EST news160212951 Just when the Food and Drug Administration is reconsidering the use of stimulants to treat asthma, a new research study offers further evidence to support a University of Houston professor's theory that an opposite approach to asthma treatment may be in order. http://www.physorg.com/news152213148.html Medicine & Health Mon, 26 Jan 2009 17:26:08 EST news152213148 A compound designed to prevent chest pains in heart patients has shown promising results in animal studies, say scientists. In the second issue of the British Journal of Pharmacology to be published by Wiley-Blackwell, researchers from the Centre de Recherche Pierre Fabre in France, show that the novel compound F15845 has anti-angina activity and can protect heart cells from damage without the unwanted side effects often experienced with other drugs. http://www.physorg.com/news150536526.html Medicine & Health Wed, 07 Jan 2009 07:42:06 EST news150536526 (PhysOrg.com) -- A newly discovered chemical pathway that helps protect heart tissue can be stimulated by two of 20 common beta-blockers, drugs that are prescribed to millions of patients who have experienced heart failure. http://www.physorg.com/news140694238.html Medicine & Health Mon, 15 Sep 2008 10:43:58 EST news140694238
