Hypertensive patients with coronary artery disease had similar outcomes when they took a beta-blocker therapy or a calcium antagonist-based therapy, according to a study in the December 3 issue of The Journal of the American Medical Association (JAMA).
According to background information in the article, despite conclusive evidence of the effectiveness of medications to treat high blood pressure in patients with hypertension in general, safety and efficacy of antihypertensive medications in patients with coronary artery disease (CAD) have been discerned only from the analyses of subgroups in large trials.
Carl J. Pepine, M.D., of the University of Florida College of Medicine, Gainesville, Fla., and colleagues designed a randomized trial, the International Verapamil-Trandolapril Study (INVEST), to compare outcomes in older hypertensive patients with CAD treated with a calcium antagonist strategy (CAS; verapamil sustained release [SR]) or a beta-blocker, non-calcium antagonist strategy (NCAS; atenolol). Because most hypertensive patients require more than 1 agent to adequately control blood pressure, INVEST was intended to compare multidrug strategies rather than individual agents. The study included 22,576 hypertensive CAD patients aged 50 years or older, and was conducted September 1997 to February 2003 at 862 sites in 14 countries.

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...
