Heart failure is the leading cause of hospitalization among persons 65 and older, and admissions for its symptoms have increased by 155 percent over the last 20 years. This raises concerns about an epidemic that involves more new cases of heart failure. But improved survival with heart failure, not an increase in disease rates, is responsible for this epidemic of hospital admissions, according to findings of a Mayo Clinic study published this week in the Journal of the American Medical Association.
The study of Olmsted County, Minn., residents shows that an individual’s risk of developing heart failure has not increased during the last 20 years. “This was surprising, given the large increase in hospital admissions for heart failure,” says Veronique Roger, M.D., the Mayo Clinic cardiologist and epidemiologist who led the study. “We had expected to find that heart failure has become more common. It has not. But patients with heart failure are prone to symptom flare-ups such as breathing difficulty that require emergency room visits and hospital admissions. Because they are living longer, they are being admitted to the hospital many times during the course of their disease. That’s why the number of hospitalizations is increasing rapidly even though the percentage of the population developing heart failure has remained flat.”
Overall, five-year survival from the diagnosis of heart failure improved from 43 percent in the first five years of the study to 52 percent in 1996-2000. The gains were mainly among men and younger persons. At the beginning of the study only 35 percent of men diagnosed with heart failure would be alive in five years, compared with 49 percent of women. Twenty years later, that gap had narrowed significantly, as 50 percent of men and 54 percent of women survived five years.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
