A study of more than 14,000 men and women whose hearts stopped suddenly suggests that the chances of survival are very high if such cardiac arrests are witnessed in large public venues, including airports, sports arenas or malls. The reasons, researchers say, are that almost four out of five such cases appear to be due to a survivable type of heart rhythm disruption and that big places with lots of people are more likely to have an automated external defibrillator, or AED device, handy, along with those who can apply it as well as CPR.
Breakthrough discovery offers hope for new therapies for range of diseases.
Researchers at the University of Illinois at Chicago College of Medicine have found that particular strains of a food-borne bacteria are able to invade the heart, leading to serious and difficult to treat heart infections. Their study is available online in the Journal of Medical Microbiology.

If winter continues after Groundhog's Day, extra care is required for humans.
UCLA researchers have found that a protein that plays an important role in some antioxidant therapies may not be as effective due to additional mechanisms that cause it to promote atherosclerosis, or clogging of the arteries.
A study that included more than 100,000 patients who received implantable cardioverter-defibrillators (ICDs) found that about 20 percent did not meet evidence-based guidelines for receipt of an ICD, and that these patients had a significantly higher risk of in-hospital death than individuals who met criteria for receiving an ICD, according to a study in the January 5 issue of JAMA.
Patients with diabetes, kidney disease and anemia who don’t respond to treatment with an anti-anemia drug have a higher risk of cardiovascular disease or death, researchers at UT Southwestern Medical Center have found.

Leading soy experts agree that including soyfoods in a balanced diet will have beneficial effects and improve nutrient intake among the U.S. population.
FAU investigators are the first to show a new mechanism for beneficial effects of aspirin in cardiovascular disease. Data in humans shows that all doses of aspirin used in clinical practice increase nitric oxide, which is released from the blood vessel wall, and may decrease the development and progression of plaques leading to heart attacks and strokes.

A team of Mayo Clinic researchers has found that patients with broken heart syndrome, also known as apical ballooning syndrome (ABS), have blood vessels that don’t react normally to stress. These results offer clues to the cause of this rare syndrome and may help with efforts to identify patients who are more vulnerable to mental stress so that appropriate therapies can be developed.
A hormone made by the body may be a potential therapeutic tool for the treatment of two anemic blood disorders -- beta-thalassemia and hemochromatosis. The new research was led by scientists at Weill Cornell Medical College and published in the Journal of Clinical Investigation and the journal Blood.

Eduardo Marbán, M.D., one of the most prominent cardiac stem cell researchers, will describe the latest advances during the event that begins at 1 p.m. Tuesday, Nov. 16.
Heart imaging specialists at Johns Hopkins have shown that a combination of CT scans that measure how much blood is flowing through the heart and the amount of plaque in surrounding arteries are just as good as tests that are less safe, more complex and more time-consuming to detect coronary artery disease and its severity.
Researchers have solved the structure of cystathionine beta-synthase, a protein that is integral to processes responsible for maintaining a healthy heart and nervous system.
Plaque in a heart artery looks threatening, but cardiologists know that many of these buildups will not erupt, dislodge and block a vessel, causing a heart attack that can be fatal. Some will, however, and the challenge is to figure out atherosclerotic plaque that is dangerous and treat or remove it.
Results of a UTHealth trial in which heart attack patients are given a clot buster in the back of an ambulance reveal a decrease in treatment time and subsequent less heart muscle damage.
While automated external defibrillators improve survival for out-of-hospital cardiac arrest, an analysis of data indicates their use for cardiac arrest in a hospital does not result in an improved rate of survival, according to a study in the November 17 issue of JAMA. The study is being released early online because it will be presented at the American Heart Association’s annual meeting.
Multiple testing with the cardiac diagnostic imaging technique of myocardial perfusion imaging is common, and in many patients is associated with a high cumulative estimated radiation dose, according to a study in the November 17 issue of JAMA. The study is being released early online because it is being presented at the American Heart Association’s annual meeting.
