The results of the study will be presented at the ATS 2010 International Conference in New Orleans.
"Previous clinical studies have indicated statins may play a role in lowering the risk of these conditions, but these studies have yielded variable estimates of the effect of statin therapy," said lead author Vanjul Agarwal, M.B.B.S. "In our study, we aimed to analyze and evaluate the effect of these drugs in patients with specific conditions related to vessel blockages."
While other studies have focused on the effects of specific statin drugs, Dr. Agarwal said the current analysis sought to evaluate the effect of statins as a whole. Researchers reviewed the results of 10 studies of more than 900,000 men and women evaluating the effect of statins in preventing venous thromboembolism (VTE), clots formed in the deep veins which pose a serious risk for heart attack and stroke. Dr. Agarwal noted that the current study included all types of VTE, with a focus on deep vein thrombosis (DVT), most commonly involving clots in the lower legs, and pulmonary embolism (PE), clots that form in the primary vessels of the lungs after migrating from other areas of the body, usually the legs, pelvis or, rarely, arms. According to study results, statin use benefited patients with all types of VTE, including DVT and PE.
Both PE and DVT can be asymptomatic and therefore difficult to detect, or easy to misdiagnose. According to the Centers for Disease Control, about 200,000 to 400,000 people in the U.S. have DVT and about 100,000 to 200,000 people have a PE. Nearly one-third of individuals with a PE die as a result of the condition.
Dr. Agarwal said statins are believed to decrease the risk of VTE by reducing inflammation, one of the factors involved in clot formation. "Statins have been found to have anti-inflammatory properties. Since thrombus formation involves inflammation, statins may reduce venous thrombus formation and thus, lower the odds of developing PE/DVT," she said.
Dr. Agarwal noted future randomized, controlled trials may help determine a course of statin therapy for patients most at risk for developing VTE.
"Patients at high risk for developing PE or DVT may be prescribed statins prophylactically," she said. "In these patients, regular use of statins could significantly reduce the incidence of PE and DVT."

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
