Carvedilol shown to have unique characteristics among beta blockers
In a new study, researchers report that a class of heart medications called beta-blockers can have a helpful, or harmful, effect on the heart, depending on their molecular activity. view more (2009-11-23)
Effect of real-time CPR feedback reported at resuscitation science symposium
Emergency medical service (EMS) providers in the United States assess an estimated 350,000 cardiac arrests each year. Only 5 to 10 percent of people who have sudden cardiac arrest survive. Better quality cardiopulmonary resuscitation (CPR) provided by prehospital EMS providers may be associated with better patient outcome. view more (2009-11-23)
New understanding about mechanism for cell death after stroke leads to possible therapy
Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. view more (2009-11-23)
Drug for erectile dysfunction improves heart function in young heart-disease patients
Heart function significantly improved in children and young adults with single-ventricle congenital heart disease who have had the Fontan operation following treatment with sildenafil, a drug used to treat erectile dysfunction and pulmonary hypertension, say researchers from The Children's Hospital of Philadelphia. view more (2009-11-19)
Inhibition of GRK2 is protective against acute cardiac stress injuries
Inhibition of a protein known to contribute to heart failure also appears to be protective of the heart in more acute cardiac stress injury, namely ischemia reperfusion. view more (2009-11-18)
Fat collections linked to decreased heart function
Researchers from Boston University School of Medicine (BUSM) have shown that fat collection in different body locations, such as around the heart and the aorta and within the liver, are associated with certain decreased heart functions. view more (2009-11-16)
Young athletes need dual screening tests for heart defects, study suggests
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins. view more (2009-11-16)
Continuous chest compression-CPR improved cardiac arrest survival in Arizona
The chance of surviving a cardiac arrest outside a hospital was found to be twice as high when bystanders performed continuous chest compressions without mouth-to-mouth breathing than when bystanders performed standard CPR. view more (2009-11-16)
Cornell researchers identify a weak link in cancer cell armor
The seeming invincibility of cancerous tumors may be crumbling, thanks to a promising new gene therapy that eliminates the ability of certain cells to repair themselves. view more (2009-11-13)
Size matters: Obesity leading risk factor of left atrial enlargement during aging
Aside from aging itself, obesity appears to be the most powerful predictor of left atrial enlargement (LAE), upping one's risk of atrial fibrillation (the most common type of arrhythmia), stroke and death. view more (2009-11-10)
Less than 1 in 3 Toronto bystanders who witness a cardiac arrest try to help: Study
Researchers at St. Michael's Hospital working in conjunction with EMS services, paramedics and fire services across Ontario found that a bystander who attempts cardiopulmonary resuscitation (CPR) can quadruple the survival rate to over 50 per cent. view more (2009-11-09)
NHLBI stops enrollment in study on resuscitation methods for cardiac arrest
Enrollment has ended early in a large, multicenter clinical trial comparing two distinct resuscitation strategies delivered by emergency medical service (EMS) providers to increase blood flow during cardiac arrest. view more (2009-11-09)
New methods found useful for diagnosing myocarditis
Myocarditis is an important, and often unrecognized cause of dilated cardiomyopathy (DCM). Several new diagnostic methods, such as cardiac magnetic resonance imaging (MRI), are useful for diagnosing myocarditis, according to a study published in the November 2009 issue of Mayo Clinic Proceedings. view more (2009-11-04)
Pandemic flu vaccine campaigns may be undermined by coincidental medical events
The effectiveness of pandemic flu vaccination campaigns - like that now underway for H1N1 - could be undermined by the public incorrectly associating coincidental and unrelated health events with the vaccines. view more (2009-11-02)
Researchers develop innovative imaging system to study sudden cardiac arrest
A research team at Vanderbilt University has developed an innovative optical system to simultaneously image electrical activity and metabolic properties in the same region of a heart, to study the complex mechanisms that lead to sudden cardiac arrest. view more (2009-11-02)
For dialysis patients, skinny is dangerous
Dialysis patients with low body fat are at increased risk of death-even compared to patients at the highest level of body fat percentage, according to research being presented at the American Society of Nephrology's 42nd Annual Meeting and Scientific Exposition in San Diego. view more (2009-11-02)
Experts unveil new CVD guidelines and position papers
Several new guidelines and position papers offering the most up to date information to ensure that clinicians practice evidence-based medicine were released at the Canadian Cardiovascular Congress 2009 this week. view more (2009-10-28)
Mayo Clinic study shows people with heart devices can 'digest' advanced diagnostic technology safely
A new Mayo Clinic study suggests that video capsule endoscopy (CE), a procedure that uses wireless technology in diagnosing intestinal disease, is safe for patients with heart devices. view more (2009-10-27)
Barrett's esophagus patients have same survival rates as general population
New Mayo Clinic research has found that survival rates of patients with Barrett's esophagus, which can be a precursor for esophageal cancer, are no different than the survival rates for the general population. view more (2009-10-27)
Canadian scientists link fat hormone to death from potentially deadly blood infection
A new Canadian study has found that lower-than-normal levels of a naturally-occurring fat hormone may increase the risk of death from sepsis-an overwhelming infection of the blood which claims thousands of lives each year. view more (2009-10-26)
