The use of antidepressants in patients who have suffered a heart attack appears to reduce the risk of recurrent events and cardiac death, according to a large, multi-center study conducted by the National Heart, Lung and Blood Institute. The findings suggest that post-heart attack patients who suffer from depression should talk with their physicians about taking the medication.
"Our study provides much stronger evidence than weve ever had before that antidepressants are safe and may benefit these patients," said C. Barr Taylor, MD, professor of psychiatry and behavioral sciences at the Stanford University School of Medicine and lead author of the paper published in the July issue of Archives of General Psychiatry.
Cardiovascular disease, the leading cause of death, major morbidity and disability in the United States, is often linked with depression: according to past studies, 20 percent of patients with coronary heart disease suffer from major depression and 20 percent from minor depression. Studies have also shown that depression among post-heart attack patients is associated with death and recurrent heart attacks.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
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....
