Stroke risk significant in month following heart attack
"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.

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
