Joanna Chikwe, MD, has been appointed as Chief of the Division of Cardiothoracic Surgery in the Department of Surgery at Stony Brook University School of Medicine. Henry J. Tannous, MD, has been named Clinical Associate Professor of Surgery in the Division of Cardiothoracic Surgery in the Department of Surgery.
New research from a fluid mechanics team in Greece reveals how blood flow dynamics within blood vessels may influence where plaques develop or rupture this week in Physics of Fluids. The findings could one day help doctors identify weak spots on a vessel wall that are likeliest to fail, and lead to early interventions in treating heart disease.
The Mount Sinai Hospital is the first site in the New York metropolitan area to pioneer a new approach for the treatment of cardiac arrhythmias using the EpiAccess® system.
Researchers at the Peter Munk Cardiac Centre, with expertise running large clinical trials, and at Mayo Clinic, are leading the Tailored Antiplatelet Therapy to Lessen Outcomes after Percutaneous Coronary Intervention (TAILOR-PCI) study. This study has received $7 million in additional funding from the National Heart, Lung and Blood Institute (NHLBI) of the National Institutes of Health (NIH).
A UCLA study is the first to show that Latinos age at a slower rate than other ethnic groups. The findings may one day help scientists understand how to slow the aging process for everyone.
Sedentary behavior — even among physically active people — may be associated with an increased risk of heart disease, diabetes and more.
Though mortality from heart disease is decreasing, some groups are at increased risk for developing heart disease, including African Americans in the southeastern U.S. Nearly 44 percent of all African American men, and 48 percent of African American women have some form of cardiovascular disease, including heart disease or stroke.
Commonly touted as “good cholesterol” for helping to reduce risk of stroke and heart attack, both high and low levels of high-density lipoprotein (HDL) cholesterol may increase a person’s risk of premature death, according to new research at Washington University School of Medicine in St. Louis and Veterans Affairs St. Louis Health Care System. Conversely, intermediate HDL cholesterol levels may increase longevity, according to the research.
A Cornell study recently published online in the peer-reviewed journal Molecular Nutrition and Food Research reports new results that raise questions about whether circulating TMAO causes heart disease or whether it is simply a biomarker, or a sign, of developing disease.
On top of offering sound advice, NYU Lutheran also provides pregnant women with important clinical information about their pregnancies — using the most advanced ultrasound technology to assess how their baby is developing inside the womb.
Mayo Clinic has launched a new type of blood test that will be used to predict adverse cardiovascular events in patients with progressing coronary artery disease (CAD). The test measures blood concentrations of plasma ceramides, a class of lipids that are highly linked to cardiovascular disease processes.
Previous research has shown that sitting for an extended period of time at a computer or during a long airline flight reduces blood flow to the legs, which may contribute to the development of cardiovascular disease. Now, researchers from the University of Missouri have found that fidgeting while sitting can protect the arteries in legs and potentially help prevent arterial disease.
Researchers at Wake Forest Baptist Medical Center have successfully tested a prototype conducted electrical weapon (CEW) capable of recording a subject’s heart rate and rhythm while still delivering incapacitating electrical charges.
Cardiovascular diseases are the leading cause of death in the U.S. With one in every four deaths occurring each year, the five-year survival rate after a heart attack is worse than most cancers. A big part of the problem is the inability of the human heart to effectively repair itself after injury. A team of University of Houston researchers is trying to change that.
Researchers have uncovered how genes identified from genome-wide association studies (GWAS) affect high-density lipoprotein cholesterol (HDL-C), a biomarker of cardiovascular disease, after comparing several animal models with human patient data. A large team from the Perelman School of Medicine at the University of Pennsylvania, the University of Copenhagen, Bristol-Myers Squibb and several others institutions detail their findings in a paper published today in Cell Metabolism.
Patients with sickle cell anemia (SCA) develop heart complications and nearly a quarter die a sudden death. Now, researchers have linked malfunctioning molecular pathways to specific heart anomalies in SCA that result from progressive fibrosis and result in sudden death. A study published online this week by PNAS (Proceedings of the National Academy of Sciences) reports the findings open a path to earlier non-invasive diagnosis and development of new targeted therapies to help SCA patients live longer with better quality of life.
Among patients with severe aortic stenosis (narrowing of the aortic valve) undergoing transcatheter aortic valve implantation, the use of a cerebral protection device (a filter that captures debris [tissue and plaque] dislodged during the procedure) reduced the number and volume of brain lesions, according to a study appearing in the August 9 issue of JAMA.
The new testing method is a significant improvement for patients because it utilizes a simple blood sample, eliminating the need for a much more invasive lung biopsy that was previously required to test for the genetic mutation.
Though the health systems in Brazil, Colombia, El Salvador, Jamaica, Mexico and Panama have considerable strengths, citizens still reported gaps in the way primary care is organized, financed and delivered in those countries. Those who had better experiences were less likely to say that their health system needed major reforms.
Scientists have shown that people who exercise for even a few hours each week can enlarge their hearts. This is a normal and beneficial response to exercise, but until now has only been recognised in athletes. The researchers say that doctors should now consider an individual’s activity level before diagnosing common heart conditions.
