Heart pumps save lives

15.06.2010
Heart failure is a very common condition: around 200,000 people in Sweden have been diagnosed with the disease. Some patients with life-threatening heart failure can be helped by mechanical heart pumps, reveals a thesis from the University of Gothenburg, Sweden.

Heart failure is a very common condition: around 200,000 people in Sweden have been diagnosed with the disease. Some patients with life-threatening heart failure can be helped by mechanical heart pumps, reveals a thesis from the University of Gothenburg, Sweden.

In the thesis, a total of 99 patients with life-threatening heart failure were treated with a heart pump for short- or long-term circulatory support.

“Two-thirds of these patients survived,” says Hans Lidén, a researcher at the Sahlgrenska Academy and consultant thoracic surgeon at Sahlgrenska University Hospital. “A total of around 300 patients have been treated with heart pumps at the hospital over the years – and with good results.”

Heart pumps for short-term support are used mainly for young and middle-aged patients with acute problems, such as heart attacks. Heart pumps for long-term support are normally used for patients with chronic heart failure who are so ill that they are not expected to survive the wait – or the operation – for a new heart.

“In the group given short-term support, around half the patients recovered sufficient heart function to be able to return home,” says Lidén.
Most patients given long-term support have gone on to have heart transplants.
The main finding of the thesis is that this treatment can improve survival among patients with life-threatening heart failure.
HEART FAILURE
Around 200,000 people in Sweden have been diagnosed with heart failure, and estimates suggest a similar number of undiagnosed cases. Impairment of the heart’s function means that it pumps out less blood than the body needs. The most common symptoms are tiredness, shortness of breath and swelling (oedema) in the lower leg. The severest forms of heart failure are as deadly as the most serious forms of cancer, and quality of life is substantially reduced.

Im Focus: Flexible proximity sensor creates smart surfaces

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...

Im Focus: Manipulating Electron Spins Without Loss of Information

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...

Im Focus: The proton precisely weighted

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...
