While extreme obesity has been associated with heart failure, until now, data have been limited regarding the influence of overweight and lesser degrees of obesity on the risk of this disease. According to a new study supported by the National Heart, Lung, and Blood Institute (NHLBI), excess body weight is strongly and independently associated with an increased risk of heart failure. This risk, which increases continuously with increasing degrees of body weight, is 34 percent higher for overweight individuals and 104 percent higher for obese persons.
The large, community-based study investigated the relations between body mass index (BMI), a measure of excess weight for height, and the risk of heart failure in over 5,000 participants in the NHLBIs Framingham Heart Study, a landmark epidemiological study that began in 1948. Study findings will be published in the August 1, 2002 issue of The New England Journal of Medicine.
"Obesity has reached epidemic proportions in the United States and it is increasing," said NHLBI Director Dr. Claude Lenfant. "While the death rate from heart disease has decreased by 60 percent over the last 40 years, the death rate from heart failure has not declined. This study suggests that obesity is an important risk factor for heart failure in both women and men. Promoting optimal body weight may help reduce the burden of heart failure were seeing," he added.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
