Results of a randomised trial in this week’s issue of THE LANCET suggest that a more aggressive approach involving coronary angioplasty soon after anti-clotting medical therapy is safe and could offer a better prognosis than more conservative treatment for patients who have had heart attack.
Medical therapy to reduce blood clotting (fibrinolysis) is widely used to treat people after heart attack. Coronary angioplasty is also effective for patients with heart attack, although the time taken to transfer patients to cardiac centres limits its use. Current guidelines do not recommend angioplasty soon after medical therapy because of concerns about increased risk of bleeding and other cardiovascular problems.
Investigators in the GRACIA-1 trial assessed whether, in an era of more sophisticated angioplasty materials and newer anti-clotting agents, coronary angioplasty within 24 hours of medical therapy could improve the outcome for heart-attack patients compared with those treated conservatively (medical therapy and subsequent angioplasty if indicated by ischaemia). 500 patients from Spain and Portugal who had a heart attack accompanied by a change in ECG profile known as STEMI (ST segment elevation myocardial infharction) were randomly assigned to either type of treatment.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
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...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
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...
