Stroke risk significant in month following heart attack

06.12.2005


"While our research reaffirmed the risk of stroke among patients with heart disease, the surprise was that the risk was so high in the month after a heart attack," says Veronique Roger, M.D., M.P.H., the Mayo Clinic cardiologist who led the study.

"A lot of patients survive heart attacks today, which is why this study is so relevant," she says. "It emphasizes the importance of worrying about other things that can happen beyond heart attacks, stroke being one of them."

Researchers reviewed the medical records of 2,160 patients who received care for a heart attack at Mayo Clinic in Rochester, Minn., between 1979 and 1998 to see whether the patients had a stroke and/or died after the heart attack. Patients were followed for about six years.



In addition to the high risk in the first 30 days, the stroke risk remained two to three times higher than expected during the first three years following the heart attack. Older age, previous stroke and diabetes increased the risk for stroke, Dr. Roger says. Strokes were associated with a large increase in the risk for death after a heart attack, she says.

Researchers also discovered that the risk of stroke did not change over time. In the 20 years studied, the risk of stroke did not decrease over that period, Dr. Roger says.

The results can serve as a wake-up call to health care providers to know about this increased risk of stroke. Heart attack patients take certain medications, such as beta blockers, aspirin and those aimed at reducing cholesterol levels, which help with improving their long-term health, she says.

Smoking cessation, exercising regularly and eating healthy foods also are effective at preventing cardiovascular disease, she says.

Further studies will help define what can more specifically be done to prevent strokes after heart attacks, she says.

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,...
