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.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
