‘Polypill’ improves survival rates for heart disease sufferers
A ‘polypill’ made up of a combination of drugs could extend the lives of thousands of patients with coronary heart disease, say researchers at The University of Nottingham.
The study, published in the latest British Medical Journal, found that combinations of cholesterol lowering drugs (statins), aspirin and beta-blockers, which lower blood pressure, improve survival rates in high-risk patients with cardiovascular disease.
However, despite proposals in the past that these drugs, combined into a ‘polypill’ with folic acid, should be given to all patients over the age of 55, the researchers found no evidence that this would be beneficial.
This is the first large-scale, long-term trial to look at the effect of different combinations of drugs to prevent deaths of patients with heart disease.
The study, led by Professor Julia Hippisley-Cox in the University’s Centre for Population Sciences, involved more than 13,000 patients who were diagnosed with ischaemic heart disease between 1996 and 2003.
The combination of statins, aspirin and beta-blockers appeared to improve survival rates most effectively — by 83 per cent. Adding another type of blood pressure lowering drug (an angiotensin converting enzyme (ACE) inhibitor) offered no extra benefit. At 19 per cent, beta-blockers alone were the least successful. ACE inhibitors offered just a 20 per cent reduction in risk.
The data came from the QRESEARCH database, run by The University of Nottingham in collaboration with the IT software provider EMIS. QRESEARCH automatically collects real-time data from 500 GP practices (representing around eight million patients) throughout the UK. The system anonymises and uploads practices’ clinical data to a central database.

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...
