Researchers at the University of Pennsylvania School of Medicine and the School of Arts and Sciences have shown that a well-known protein structure acts as a molecular spring, explaining one way that clots may stretch and bend under such physical stresses as blood flow. This knowledge will inform researchers about clot physiology in such conditions as wound healing, stroke and cardiovascular disease.
An inexpensive blood test may identify which heart disease patients are at the highest risk of a stroke or heart attack, allowing doctors to move more aggressively to help them. “We are very good in this country at diagnosing heart disease,” said Kirsten Bibbins-Domingo, of the University of California-San Francisco, lead author of the study.
A survey of hospital death rates for almost 47,000 people with heart attacks, stroke, pneumonia and blood poisoning has revealed that 30-day death rates varied from 10 percent to 28 percent across 75 hospitals. The researchers also surveyed some 4,000 nurses and came up with a list of key factors which accounted for the variance.
Cardiac surgeons in New York State who are less experienced with the recently introduced off-pump techniques in coronary bypass surgery are more likely to perform such operations on black patients, according to new research.
Anthony Koleske, associate professor of molecular biophysics and biochemistry and neurobiology at Yale School of Medicine, has been awarded the $500,000 Established Investigator Award from the American Heart Association (AHA).
A blood test for patients with coronary heart disease could help predict their risk for subsequent cardiovascular events or death, according to a study in the Jan_10 issue of JAMA.
A simple blood test for the protein NT-proBNP accurately predicts the risk of heart attack, heart failure, stroke and death in patients with known cardiovascular disease, according to a study led by a researcher at the San Francisco VA Medical Center.
A new study finds that obesity increases the risk of death from prostate cancer, even though it does not increase the overall risk a man will be diagnosed with the disease. The study reveals that higher body mass index (BMI) and weight gain in adulthood correlated strongly with increased risk of death from prostate cancer.
Scientists have discovered a new source of stems cells and have used them to create muscle, bone, fat, blood vessel, nerve and liver cells in the laboratory. The first report showing the isolation of broad potential stem cells from the amniotic fluid that surrounds developing embryos was published today in Nature Biotechnology.
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function.
