Aging Population, Longer Survival with Disease Magnify Heart Failure “Epidemic”

22.07.2004


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.



“This study has important medical and public health implications,” says Dr. Roger. “First, although we have made some progress, we need to continue working to improve survival. Men remain at higher risk for heart failure at a younger age than women, and a five-year mortality of about 50 percent for either sex is a poor prognosis. We also need to improve our approach to treat these symptom flare-ups in the outpatient setting instead of repeatedly admitting these patients to the hospital. Otherwise, as the population ages, we will see hospitalizations for heart failure continue to increase, which is burdensome for our patients as well as for the health care system. Being able to remain at home instead of in the hospital would contribute to an improved quality of life for these patients.”

Co-authors of the paper, “Trends in Heart Failure Incidence and Survival in a Community-Based Population,” include Susan Weston; Margaret Redfield, M.D., Jens Hellermann-Homan, M.D.; Jill Killian; Barbara Yawn, M.D. and Steven Jacobsen, M.D., Ph.D.

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
