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: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
