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.

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...
