The most emergent form of heart attacks is decreasing nationwide, but this declining incidence could affect emergency departments' quality and timeliness of care.

This is the key finding of a Vanderbilt University study released today in the American Journal of Cardiology and presented at the national American Heart Association meeting in Chicago this week.

NEW YORK (November 18, 2014) - The addition of mitral valve (MV) repair (a valve of the heart) to coronary artery bypass grafting (CABG), a type of open-heart surgery, did not result in significant benefit to the patient and was associated with increased risk of neurological events. Therefore, the routine addition of MV repair to CABG in patients with moderate IMR did not demonstrate a clinically meaningful advantage.

Motor vehicle crashes are the most common cause of unintentional life lost around the world, with about 30,000 deaths occurring annually in the U.S. due to motor-vehicle crashes.

A study by a doctoral student in epidemiology at the Indiana University Richard M. Fairbanks School of Public Health at Indiana University-Purdue University Indianapolis showed that vehicle inequities have a significant impact on survivability in head-on collisions.

WASHINGTON D.C., November 18, 2014 -- A research team from Germany developed an analytical model to describe the structural dynamics of photoexcited thin films and verified it by ultrafast X-ray diffraction.

Lattice dynamics, atomic movements in a crystal structure, can influence the physical and chemical properties of a material. The phenomenon can be directly studied using ultrafast X-ray diffraction, in which femtosecond X-ray pulses take snapshots of the atomic positions in a crystal by interacting with the structure at the core electronic level.

Researchers at the Bellvitge Biomedical Research Institute (IDIBELL) and doctors at University Hospital of Bellvitge, together with a team of researchers from the University of California, Cincinnati Children's Hospital, California Pacific Medical Center, University of Pittsburgh, University Emory and Stanford University (USA) and the Children's Hospital of Mexico Federico Gomez, have developed a genetic test that identifies patients at high risk of kidney transplant rejection.

Scientists in Australia have used historic media to measure the decline in Queensland's pink snapper fishery, highlighting a drop of almost 90 per cent in catch rates since the 19th Century.

Researchers from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at the University of Queensland and the Department of Agriculture Fisheries and Forestry examined thousands of newspaper articles dating back to1870 to reveal the historic catch rates for the iconic Queensland fishery.

Cocaine users complaining of chest pain may have abnormal blood flow in the heart's smallest blood vessels that may not be detected in regular testing, putting these patients at risk for heart complications or death, according to research presented at the American Heart Association's Scientific Sessions 2014.
