For embolism patients, clot-busting drug is worth risk

22.02.2013
When doctors encounter a patient with a massive pulmonary embolism, they face a difficult choice: Is it wise to administer a drug that could save the patient’s life, even though many people suffer life-threatening bleeding as a result?
Based on new findings published in the American Journal of Medicine, Michigan State University researchers are answering that question in no uncertain terms.

“The message to doctors is clear: Take the chance,” said Paul D. Stein, a professor in MSU’s Department of Osteopathic Medical Specialties. “It doesn’t matter how old the patient is or what other chronic diseases the patient has. Administering the drug saves lives.”

Pulmonary embolism is a potentially deadly blockage of arteries in the lungs caused by blood clots that travel from elsewhere in the body, usually the leg. Clot-dissolving drugs known as thrombolytic agents often can remove the blockage, but they also can cause brain hemorrhages and other major bleeding.

Stein found in an earlier study that only about a third of unstable pulmonary embolism patients – those who are in shock or require a ventilator – received thrombolytic therapy, even though the drugs decreased the risk of dying in the hospital from 50 percent to 15 percent.

“Doctors are smart,” Stein said, “so why are only a third of patients getting the drug?”

To find out, Stein and Fadi Matta, MSU associate professor of osteopathic medical specialties, reviewed a national database of records from more than 1,000 hospitals. Their findings suggest that concern over the bleeding associated with thrombolytic therapy may keep doctors from giving the drug to patients who could be at higher risk.

In the study, only 20 percent of unstable patients with associated chronic conditions received the drug, compared to 80 percent of those without such conditions. Patients older than 60 also were less likely to receive the treatment.

Yet, even if patients had associated chronic conditions in addition to pulmonary embolism, the in-hospital death rate was 20 percent among those who received thrombolytic therapy, compared to 47 percent of those who did not get the clot-dissolving drug. The death rate also was lower among elderly patients who got the drug.

“Physicians apparently are afraid to give thrombolytic drugs to pulmonary embolism patients if they are elderly or have associated illnesses, and for good reason,” Stein said. “Bleeding can be severe with such drugs, but the fact is, a lot more patients die if they don’t get the drug than if they do.”

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

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...

Im Focus: Visual intelligence is not the same as IQ

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...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

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....

Im Focus: Researchers Develop Data Bus for Quantum Computer

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,...
