Stroke patients admitted to the hospital on the weekend appear more likely to receive the clot-dissolving medication tissue plasminogen activator than patients admitted during the week, according to a report in the January issue of Archives of Neurology. However, stroke death rates appear similar among weekend and weekday admissions. http://phys.org/news182452118.html Medicine & Health Mon, 11 Jan 2010 18:10:02 EST news182452118 (PhysOrg.com) -- The American Heart Association estimates 700,000 Americans will experience a myocardial infarction, or heart attack, each year. For the most severe cases, patient outcome often depends on the speed with which a patient is diagnosed and transported to a catheterization lab. http://phys.org/news182185446.html Medicine & Health Fri, 08 Jan 2010 15:20:01 EST news182185446 A new study conducted at Ben-Gurion University of the Negev (BGU) reveals that Celebrex and other anti-inflammatory coxib medications may counter the positive effects of aspirin in preventing blood clots. http://phys.org/news180806540.html Medicine & Health Wed, 23 Dec 2009 16:20:04 EST news180806540 The cellulose produced by bacteria could be used for artificial blood vessels in the future as it carries a lower risk of blood clots than the synthetic materials currently used for bypass operations, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden. http://phys.org/news180708595.html Medicine & Health Tue, 22 Dec 2009 13:00:06 EST news180708595 Computed tomography (CT), a highly accurate, readily available medical imaging technique, is the overwhelmingly preferred technique of emergency physicians and radiologists for the diagnosis of pulmonary embolism (PE), according to a study in the January issue of the American Journal of Roentgenology. http://phys.org/news180706569.html Medicine & Health Tue, 22 Dec 2009 12:30:01 EST news180706569 Bobbie Laird was suffering a life-threatening stroke triggered by a blood clot in her brain that was nearly half an inch long. http://phys.org/news180118964.html Medicine & Health Tue, 15 Dec 2009 17:20:15 EST news180118964 Millions of Americans take Celebrex for arthritis or other pain. Many, if they are middle-aged or older, also take a low-dose aspirin tablet daily to reduce the risk of heart attack and stroke. Yet they may be getting little protection, because Celebrex keeps the aspirin from doing its job effectively, a new study suggests. http://phys.org/news180040030.html Medicine & Health Mon, 14 Dec 2009 21:10:03 EST news180040030 Polyphosphate from blood platelets plays a key role in inflammation and the formation of blood clots, scientists from the Swedish medical university Karolinska Institutet have shown.

New research presented at the 75th annual international scientific assembly of the American College of Chest Physicians (ACCP), shows that patients with atherosclerosis receiving statin therapy had a significantly reduced risk of developing venous thromboembolism (VTE)—a collective term for DVT (blood clot) and pulmonary embolism (PE)—than patients not on statin therapy. Furthermore, patients on a higher dose of statins had the least likelihood of developing VTE. http://phys.org/news176478450.html Medicine & Health Tue, 03 Nov 2009 14:20:02 EST news176478450 William Kuo, MD, was the on-call interventional radiologist one Friday night three years ago when he received a call from the intensive care unit at Stanford Hospital & Clinics.

Scientists at Heidelberg University Hospital have explained the mechanism of this clinical paradox for the first time on an animal model. Mice with a greater tendency to form blood clots have larger plaques in their vessels, but they are more stable. Thus, there is less risk that these plaques will rupture and obstruct circulation. The results of the study have been published in the prestigious journal Circulation. http://phys.org/news170328047.html Medicine & Health Mon, 24 Aug 2009 10:21:46 EST news170328047 (AP) -- Abbott Laboratories Inc. is expanding a study of its top-selling heart stent by more than 2,000 patients, who may also be put in a second, landmark stent study meant to find the best way to prevent potentially fatal blood clots. http://phys.org/news169384157.html Medicine & Health Thu, 13 Aug 2009 12:09:44 EST news169384157 The dean of the University of Oklahoma College of Public Health and a team of scientists worldwide have found a better way to prevent deadly blood clots after joint replacement surgery - a major problem that results in thousands of unnecessary deaths each year.
