Researchers find drugs boost survival in those with congestive heart failure and mitral regurgitation with normal ejection fraction
Beta-blockers, medications that block the action of certain hormones on the heart, can benefit patients with certain serious heart problems such as diastolic heart failure, according to cardiologists at the Keck School of Medicine of the University of Southern California and Loma Linda University Medical Center.
Researchers presented two reports on the use of beta-blockers in patients with chronic severe mitral regurgitation, or MR, and congestive heart failure, CHF, at the American College of Cardiologys 54th Annual Scientific Session on March 7. These patients had a normal ejection fraction, a measure of how well the heart pumps out blood. "Our findings are encouraging because there are no data on the survival benefit of medical therapy in CHF or severe MR patients with normal ejection fraction. CHF with normal ejection fraction, popularly referred to as diastolic heart failure, makes up nearly 50 percent of all CHF patients-and these patients have very similar mortality and morbidity as those with reduced ejection fraction," says Padmini Varadarajan, M.D., advanced cardiac imaging fellow in the Department of Cardiovascular Medicine at the Keck School of Medicine and the studys lead author.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
